+@chapter Libgloss
+Libgloss is a library for all the details that usually get glossed over.
+This library refers to things like startup code, and usually I/O support
+for @code{gcc} and @code{C library}. The C library used through out
+this manual is @code{newlib}. Newlib is a ANSI conforming C library
+developed by Cygnus Support. Libgloss could easily be made to
+support other C libraries, and it can be used standalone as well. The
+standalone configuration is typically used when bringing up new
+hardware, or on small systems.
+
+For a long time, these details were part of newlib. This approach worked
+well when a complete tool chain only had to support one system. A tool
+chain refers to the series of compiler passes required to produce a
+binary file that will run on an embedded system. For C, the passes are
+cpp, gcc, gas, ld. Cpp is the preprocessor, which process all the header
+files and macros. Gcc is the compiler, which produces assembler from the
+processed C files. Gas assembles the code into object files, and then ld
+combines the object files and binds the code to addresses and produces
+the final executable image.
+
+Most of the time a tool chain does only have to support one target
+execution environment. An example of this would be a tool chain for the
+AMD 29k processor family. All of the execution environments for this
+processor are have the same interface, the same memory map, and the same
+I/O code. In this case all of the support code is in newlib/sys/FIXME.
+Libgloss's creation was forced initially be the @code{cpu32} processor
+family. There are many different execution environments for this line,
+and they vary wildly. newlib itself has only has a few dependencies that
+it needs for each target. These are explained later in this doc. The
+hardware dependent part of newlib was reorganized into a separate
+directory structure within newlib called the stub dirs. It was initially
+called this because most of the routines newlib needs for a target were
+simple stubs that do nothing, but return a value to the application. They
+only exist so the linker can produce a final executable image. This work
+was done during the early part of 1993.
+
+After a while it became apparent that this approach of isolating the
+hardware and systems files together made sense. Around this same time
+the stub dirs were made to run standalone, mostly so it could also be
+used to support GDB's remote debugging needs. At this time it was
+decided to move the stub dirs out of newlib and into it's own separate
+library so it could be used standalone, and be included in various other
+GNU tools without having to bring in all of newlib, which is large. The
+new library is called Libgloss, for Gnu Low-level OS support.

+@node Sparclite, CPU32, , Supported targets
+@subsection Sparclite Targets Supported
+@c FIXME: put links to the docs in etc/targetdoc
+This is for the Fujitsu Sparclite family of processors. Currently this
+covers the ex930, ex931, ex932, ex933, and the ex934. In addition to the
+I/O code a startup file, this has a GDB debug-stub that gets linked into
+your application. This is an exception handler style debug stub. For
+more info, see the section on Porting GDB. @ref{GDB,,Porting GDB}.
+
+The Fujitsu eval boards use a host based terminal program to load and
+execute programs on the target. This program, @code{pciuh} is relatively
+new (in 1994) and it replaced the previous ROM monitor which had the
+shell in the ROM. GDB uses the the GDB remote protocol, the relevant
+source files from the gdb sources are remote-sparcl.c. The debug stub is
+part of libgloss and is called sparcl-stub.c.
+
+@node CPU32, Mips, Sparclite, Supported targets
+@subsection Motorola CPU32 Targets supported
+This refers to Motorola's m68k based CPU32 processor family. The crt0.S
+startup file should be usable with any target environment, and it's
+mostly just the I/O code and linker scripts that vary. Currently there
+is support for the Motorola MVME line of 6U VME boards and IDP
+line of eval boards. All of the
+Motorola VME boards run @code{Bug}, a ROM based debug monitor.
+This monitor has the feature of using user level traps to do I/O, so
+this code should be portable to other MVME boards with little if any
+change. The startup file also can remain unchanged. About the only thing
+that varies is the address for where the text section begins. This can
+be accomplished either in the linker script, or on the command line
+using the @samp{-Ttext [address]}.
+
+@c FIXME: Intermetrics or ISI wrote rom68k ?
+There is also support for the @code{rom68k} monitor as shipped on
+Motorola's IDP eval board line. This code should be portable across the
+range of CPU's the board supports. There is also GDB support for this
+target environment in the GDB source tree. The relevant files are
+gdb/monitor.c, monitor.h, and rom58k-rom.c. The usage of these files is
+discussed in the GDB section.
+
+@node Mips, PA-RISC, CPU32, Supported targets
+@subsection Mips core Targets Supported
+The Crt0 startup file should run on any mips target that doesn't require
+additional hardware initialization. The I/O code so far only supports a
+custom LSI33k based RAID disk controller board. It should easy to
+change to support the IDT line of eval boards. Currently the two
+debugging protocols supported by GDB for mips targets is IDT's mips
+debug protocol, and a customized hybrid of the standard GDB remote
+protocol and GDB's standard ROM monitor support. Included here is the
+debug stub for the hybrid monitor. This supports the LSI33k processor,
+and only has support for the GDB protocol commands @code{g}, @code{G},
+@code{m}, @code{M}, which basically only supports the register and
+memory reading and writing commands. This is part of libgloss and is
+called lsi33k-stub.c.
+
+The crt0.S should also work on the IDT line of eval boards, but has only
+been run on the LSI33k for now. There is no I/O support for the IDT eval
+board at this time. The current I/O code is for a customized version of
+LSI's @code{pmon} ROM monitor. This uses entry points into the monitor,
+and should easily port to other versions of the pmon monitor. Pmon is
+distributed in source by LSI.
+
+@node PA-RISC, , Mips, Supported targets
+@subsection PA-RISC Targets Supported
+This supports the various boards manufactured by the HP-PRO consortium.
+This is a group of companies all making variations on the PA-RISC
+processor. Currently supported are ports to the WinBond @samp{Cougar}
+board based around their w89k version of the PA. Also supported is the
+Oki op50n processor.
+
+There is also included, but never built an unfinished port to the HP 743
+board. This board is the main CPU board for the HP700 line of industrial
+computers. This target isn't exactly an embedded system, in fact it's
+really only designed to load and run HP-UX. Still, the crt0.S and I/O
+code are fully working. It is included mostly because their is a barely
+functioning exception handler GDB debug stub, and I hope somebody could
+use it. The other PRO targets all use GDB's ability to talk to ROM
+monitors directly, so it doesn't need a debug stub. There is also a
+utility that will produce a bootable file by HP's ROM monitor. This is
+all included in the hopes somebody else will finish it. :-)
+
+Both the WinBond board and the Oki board download srecords. The WinBond
+board also has support for loading the SOM files as produced by the
+native compiler on HP-UX. WinBond supplies a set of DOS programs that
+will allow the loading of files via a bidirectional parallel port. This
+has never been tested with the output of GNU SOM, as this manual is
+mostly for Unix based systems.
+
+@node Building libgloss, , Supported targets, Libgloss
+@subsection Configuring and building libgloss.
+
+Libgloss uses an autoconf based script to configure. Autoconf scripts
+are portable shell scripts that are generated from a configure.in file.
+Configure input scripts are based themselves on m4. Most configure
+scripts run a series of tests to determine features the various
+supported features of the target. For features that can't be determined
+by a feature test, a makefile fragment is merged in. The configure
+process leaves creates a Makefile in the build directory. For libgloss,
+there are only a few configure options of importance. These are --target
+and --srcdir.
+
+Typically libgloss is built in a separate tree just for objects. In this
+manner, it's possible to have a single source tree, and multiple object
+trees. If you only need to configure for a single target environment,
+then you can configure in the source tree. The argument for --target is
+a config string. It's usually safest to use the full canonical opposed
+to the target alias. So, to configure for a CPU32 (m68k) with a separate
+source tree, use:
+
+@smallexample
+../src/libgloss/configure --verbose --target m68k-coff
+@end smallexample
+
+The configure script is in the source tree. When configure is invoked
+it will determine it's own source tree, so the --srcdir is would be
+redundant here.
+
+Once libgloss is configured, @code{make} is sufficient to build it. The
+default values for @code{Makefiles} are typically correct for all
+supported systems. The test cases in the testsuite will also built
+automatically as opposed to a @code{make check}, where test binaries
+aren't built till test time. This is mostly cause the libgloss
+testsuites are the last thing built when building the entire GNU source
+tree, so it's a good test of all the other compilation passes.
+
+The default values for the Makefiles are set in the Makefile fragment
+merged in during configuration. This fragment typically has rules like
+
+@smallexample
+CC_FOR_TARGET = `if [ -f $$@{OBJROOT@}/gcc/xgcc ] ; \
+ then echo $@{OBJROOT@}/gcc/xgcc -B$@{OBJROOT@}/gcc/ ; \
+ else t='$@{program_transform_name@}'; echo gcc | sed -e '' $$t ; fi`
+@end smallexample
+
+Basically this is a runtime test to determine whether there are freshly
+built executables for the other main passes of the GNU tools. If there
+isn't an executable built in the same object tree, then
+@emph{transformed}the generic tool name (like gcc) is transformed to the
+name typically used in GNU cross compilers. The names are
+typically based on the target's canonical name, so if you've configured
+for @code{m68k-coff} the transformed name is @code{m68k-coff-gcc} in
+this case. If you install with aliases or rename the tools, this won't
+work, and it will always look for tools in the path. You can force the a
+different name to work by reconfiguring with the
+@code{--program-transform-name} option to configure. This option takes a
+sed script like this @code{-e s,^,m68k-coff-,} which produces tools
+using the standard names (at least here at Cygnus).
+
+The search for the other GNU development tools is exactly the same idea.
+This technique gets messier when build options like @code{-msoft-float}
+support are used. The Makefile fragments set the @code{MUTILIB}
+variable, and if it is set, the search path is modified. If the linking
+is done with an installed cross compiler, then none of this needs to be
+used. This is done so libgloss will build automatically with a fresh,
+and uninstalled object tree. It also makes it easier to debug the other
+tools using libgloss's test suites.
+
+@node GCC, Libraries, Libgloss, Top
+@chapter Porting GCC
+
+Porting GCC requires two things, neither of which has anything to do
+with GCC. If GCC already supports a processor type, then all the work in
+porting GCC is really a linker issue. All GCC has to do is produce

+The options of interest to us are @code{CPP_SPEC} and

+@subsection Compilation passes
+
+GCC by itself only compiles the C or C++ code into assembler. Typically
+GCC invokes all the passes required for you. These passes are cpp, cc1,
+gas, ld. @code{cpp} is the C preprocessor. This will merge in the
+include files, expand all macros definitions, and process all the
+@code{#ifdef} sections. To see the output of ccp, invoke gcc with the
+@code{-E} option, and the preprocessed file will be printed on the
+stdout. cc1 is the actual compiler pass that produces the assembler for
+the processed file. GCC is actually only a driver program for all the
+compiler passes. It will format command line options for the other passes.
+The usual command line GCC uses for the final link phase will have LD
+link in the startup code and additional libraries by default.
+
+GNU AS started it's life to only function as a compiler pass, but
+these days it can also be used as a source level assembler. When used as
+a source level assembler, it has a companion assembler preprocessor
+called @code{gasp}. This has a syntax similar to most other assembler
+macros packages. GAS emits a relocatable object file from the assembler
+source. The object file contains the executable part of the application,
+and debug symbols.
+
+LD is responsible for resolving the addresses and symbols to something
+that will be fully self-contained. Some RTOS's use relocatable object
+file formats like @code{a.out}, but more commonly the final image will
+only use absolute addresses for symbols. This enables code to be burned
+into PROMS as well. Although LD can produce an executable image, there
+is usually a hidden object file called @code{crt0.o} that is required as
+startup code. With this startup code and a memory map, the executable
+image will actually run on the target environment. @ref{Crt0,,Startup
+Files}.
+
+The startup code usually defines a special symbol like @code{_start}
+that is the default base address for the application, and the first
+symbol in the executable image. If you plan to use any routines from the
+standard C library, you'll also need to implement the functions that
+this library is dependent on. @ref{Libraries,,Porting Newlib}.

+@section Crt0, the main startup file
+
+To make a program that has been compiled with GCC to run, you
+need to write some startup code. The initial piece of startup code is
+called a crt0. (C RunTime 0) This is usually written in assembler, and
+it's object gets linked in first, and bootstraps the rest of the
+application when executed. This file needs to do the following things.
+
+@enumerate
+@item
+Initialize anything that needs it. This init section varies. If you are
+developing an application that gets download to a ROM monitor, then
+there is usually no need for any special initialization. The ROM monitor
+handles it for you.
+
+If you plan to burn your code in a ROM, then the crt0 typically has to
+do all the hardware initialization that is required to run an
+application. This can include things like initializing serial ports or
+run a memory check. It all depends on the hardware.
+
+@item
+Zero the BSS section. This is for uninitialized data. All the addresses in
+this section need to be initialized to zero so that programs that forget
+to check new variables default value will get unpredictable results.
+
+@item
+Call main()
+This is what basically starts things running. If your ROM monitor
+supports it, then first setup argc and argv for command line arguments
+and an environment pointer. Then branch to main(). For G++ the the main
+routine gets a branch to __main inserted by the code generator at the
+very top. __main() is used by G++ to initialize it's internal tables.
+__main() then returns back to your original main() and your code gets
+executed.
+
+@item
+Call exit()
+After main() has returned, you need to cleanup things and return control
+of the hardware from the application. On some hardware, there is nothing
+to return to, especially if your program is in ROM. Sometimes the best
+thing to do in this case is do a hardware reset, or branch back to the
+start address all over again.
+
+When there is a ROM monitor present, usually a user trap can be called
+and then the ROM takes over. Pick a safe vector with no side
+effects. Some ROMs have a builtin trap handler just for this case.

+@node Linker Scripts, What to do now, Crt0, Libraries
+@section Linker scripts for memory management
+
+The linker script sets up the memory map of an application. It also
+sets up default values for variables used elsewhere by sbrk() and the
+crt0. These default variables are typically called @code{_bss_start} and
+@code{_end}.
+
+For G++, the constructor and destructor tables must also be setup here.
+The actual section names vary depending on the object file format. For
+@code{a.out} and @code{coff}, the three main sections are @code{.text},
+@code{.data}, and @code{.bss}.
+
+Now that you have an image, you can test to make sure it got the
+memory map right. You can do this by having the linker create a memory
+map (by using the @code{-Map} option), or afterwards by using @code{nm} to
+check a few critical addresses like @code{start}, @code{bss_end}, and
+@code{_etext}.
+
+Here's a breakdown of a linker script for a m68k based target board.
+See the file @code{libgloss/m68k/idp.ld}, or go to the appendixes in
+the end of the manual. @ref{idp.ld,,Example Linker Script}.
+
+@smallexample
+STARTUP(crt0.o)
+OUTPUT_ARCH(m68k)
+INPUT(idp.o)
+SEARCH_DIR(.)
+__DYNAMIC = 0;
+@end smallexample
+
+The @code{STARTUP} command loads the file specified so that it's
+first. In this case it also doubles to load the file as well, because
+the m68k-coff configuration defaults to not linking in the crt0.o by
+default. It assumes that the developer probably has their own crt0.o.
+This behavior is controlled in the config file for each architecture.
+It's a macro called @code{STARTFILE_SPEC}, and if it's set to
+@code{null}, then when @code{gcc} formats it's command line, it doesn't
+add @code{crto.o}. Any file name can be specified here, but the default
+is always @code{crt0.o}.
+
+Course if you only use @code{ld} to link, then the control of whether or
+not to link in @code{crt0.o} is done on the command line. If you have
+multiple crto files, then you can leave this out all together, and link
+in the @code{crt0.o} in the makefile, or by having different linker
+scripts. Sometimes this is done for initializing floating point
+optionally, or to add device support.
+
+The @code{OUTPUT_ARCH} sets architecture the output file is for.
+
+@code{INPUT} loads in the file specified. In this case, it's a relocated
+library that contains the definitions for the low-level functions need
+by libc.a. This could have also been specified on the command line, but
+as it's always needed, it might as well be here as a default.
+@code{SEARCH_DIR} specifies the path to look for files, and
+@code{_DYNAMIC} means in this case there are no shared libraries.
+
+@c FIXME: Check the linker manual to make sure this is accurate.

+@node What to do now, Libc, Linker Scripts, Libraries
+@section What to do when you have a binary image
+
+A few ROM monitors load binary images, typically @code{a.out}, but most all
+will load an @code{srecord}. An srecord is an ASCII representation of a binary
+image. At it's simplest, an srecord is an address, followed by a byte
+count, followed by the bytes, and a 2's compliment checksum. A whole
+srecord file has an optional @emph{start} record, and a required @emph{end}
+record. To make an srecord from a binary image, the GNU @code{objcopy} program
+is used. This will read the image and make an srecord from it. To do
+this, invoke objcopy like this: @code{objcopy -O srec infile outfile}. Most
+PROM burners also read srecords or a similar format. Use @code{objdump -i} to
+get a list of support object files types for your architecture.
+
+@node Libc, , What to do now, Libraries
+@section Libraries
+
+This describes @code{newlib}, a freely available libc replacement. Most
+applications use calls in the standard C library. When initially linking
+in libc.a, several I/O functions are undefined. If you don't plan on
+doing any I/O, then you're OK, otherwise they need to be created. These
+routines are read, write, open, close. sbrk, and kill. Open & close
+don't need to be fully supported unless you have a filesystems, so
+typically they are stubbed out. Kill is also a stub, since you can't do
+process control on an embedded system.
+
+Sbrk() is only needed by applications that do dynamic memory
+allocation. It's uses the symbol @code{_end} that is setup in the linker
+script. It also requires a compile time option to set the upper size
+limit on the heap space. This leaves us with read and write, which are
+required for serial I/O. Usually these two routines are written in C,
+and call a lower level function for the actual I/O operation. These two
+lowest level I/O primitives are inbyte() and outbyte(), and are also
+used by GDB back ends if you've written an exception handler. Some
+systems also implement a havebyte() for input as well.
+
+Other commonly included functions are routines for manipulating
+LED's on the target (if they exist) or low level debug help. Typically a
+putnum() for printing words and bytes as a hex number is helpful, as
+well as a low-level print() to output simple strings.
+
+As libg++ uses the I/O routines in libc.a, if read and write work,
+then libg++ will also work with no additional changes.

+If there are LEDs on the board, they can also be put to use for

+than one) in sequence, creating a rotating effect. This is convenient
+between I/O to see if the target is still alive. Another useful LED
+function is @code{led_putnum()}, which takes a digit and displays it as
+a bit pattern or number. These usually have to be written in assembler
+for each target board. Here are a number of C based routines that may be
+useful.
+
+@code{led_putnum()} puts a number on a single digit segmented
+LED display. This LED is set by setting a bit mask to an address, where
+1 turns the segment off, and 0 turns it on. There is also a little

+@chapter Writing a new GDB backend
+
+Typically, either the low-level I/O routines are used for debugging, or
+LEDs, if present. It is much easier to use GDb for debugging an
+application. There are several different techniques used to have GDB work
+remotely. Commonly more than one kind of GDB interface is used to cober
+a wide variety of development needs.
+
+The most common style of GDB backend is an exception handler for
+breakpoints. This is also called a @emph{gdb stub}, and is requires the
+two additional lines of init code in your @code{main()} routine. The GDB
+stubs all use the GDB @emph{remote protocol}. When the application gets a
+breakpoint exception, it communicates to GDB on the host.
+
+Another common style of interfacing GDB to a target is by using an
+existing ROM monitor. These break down into two main kinds, a similar
+protocol to the GDB remote protocol, and an interface that uses the ROM
+monitor directly. This kind has GDB simulating a human operator, and all
+GDB does is work as a command formatter and parser.

+@end menu
+
+@node GNU remote protocol, Exception handler, ,GDB
+@section The standard remote protocol
+
+The standard remote protocol is a simple, packet based scheme. A debug
+packet whose contents are @emph{<data>} is encapsulated for transmission
+in the form:
+
+@smallexample
+ $ <data> # CSUM1 CSUM2
+@end smallexample
+
+@emph{<data>} must be ASCII alphanumeric and cannot include characters
+@code{$} or @code{#}. If @emph{<data>} starts with two characters
+followed by @code{:}, then the existing stubs interpret this as a
+sequence number. For example, the command @code{g} is used to read the
+values of the registers. So, a packet to do this would look like
+
+@smallexample
+ $g#67
+@end smallexample
+
+@emph{CSUM1} and @emph{CSUM2} are an ascii representation in hex of an
+8-bit checksum of @emph{<data>}, the most significant nibble is sent first.
+the hex digits 0-9,a-f are used.
+
+A simple protocol is used when communicating with the target. This is
+mainly to give a degree of error handling over the serial cable. For
+each packet transmitted successfully, the target responds with a
+@code{+} (@code{ACK}). If there was a transmission error, then the target
+responds with a @code{-} (@code{NAK}). An error is determined when the
+checksum doesn't match the calculated checksum for that data record.
+Upon reciept of the @code{ACK}, @code{GDB} can then transmit the next
+packet.
+
+Here is a list of the main functions that need to be supported. Each data
+packet is a command with a set number of bytes in the command packet.
+Most commands either return data, or respond with a @code{NAK}. Commands
+that don't return data respond with an @code{ACK}. All data values are
+ascii hex digits. Every byte needs two hex digits to represent t. This
+means that a byte with the value @samp{7} becomes @samp{07}. On a 32 bit
+machine this works out to 8 characters per word. All of the bytes in a
+word are stored in the target byte order. When writing the host side of
+the GDB protocol, be careful of byte order, and make sure that the code
+will run on both big and little endian hosts and produce the same answers.
+
+These functions are the minimum required to make a GDB backend work. All
+other commands are optional, and not supported by all GDB backends.
+
+@table @samp
+@item read registers @code{g}
+
+returns @code{XXXXXXXX...}
+
+Registers are in the internal order for GDB, and the bytes in a register
+are in the same order the machine uses. All values are in sequence
+starting with register 0. All registers are listed in the same packet. A
+sample packet would look like @code{$g#}.
+
+@item write registers @code{GXXXXXXXX...}
+@code{XXXXXXXX} is the value to set the register to. Registers are in
+the internal order for GDB, and the bytes in a register are in the same
+order the machine uses. All values are in sequence starting with
+register 0. All registers values are listed in the same packet. A sample
+packet would look like @code{$G000000001111111122222222...#}
+
+returns @code{ACK} or @code{NAK}
+
+@item read memory @code{mAAAAAAAA,LLLL}
+@code{AAAAAAAA} is address, @code{LLLL} is length. A sample packet would
+look like @code{$m00005556,0024#}. This would request 24 bytes starting
+at address @emph{00005556}
+
+returns @code{XXXXXXXX...}
+@code{XXXXXXXX} is the memory contents. Fewer bytes than requested will
+be returned if only part of the data can be read. This can be determined
+by counting the values till the end of packet @code{#} is seen and
+comparing that with the total count of bytes that was requested.
+
+@item write memory @code{MAAAAAAAA,LLLL:XXXXXXXX}
+@code{AAAAAAAA} is the starting address, @code{LLLL} is the number of
+bytes to be written, and @code{XXXXXXXX} is value to be written. A
+sample packet would look like
+@code{$M00005556,0024:101010101111111100000000...#}
+
+returns @code{ACK} or @code{NAK} for an error. @code{NAK} is also
+returned when only part of the data is written.
+
+@item continue @code{cAAAAAAAAA}
+@code{AAAAAAAA} is address to resume execution at. If @code{AAAAAAAA} is
+omitted, resume at the curent address of the @code{pc} register.
+
+returns the same replay as @code{last signal}. There is no immediate
+replay to @code{cont} until the next breakpoint is reached, and the
+program stops executing.
+
+@item step sAA..AA
+@code{AA..AA} is address to resume
+If @code{AA..AA} is omitted, resume at same address.
+
+returns the same replay as @code{last signal}. There is no immediate
+replay to @code{step} until the next breakpoint is reached, and the
+program stops executing.
+
+@item last signal @code{?}
+
+This returns one of the following:
+
+@itemize @bullet
+@item @code{SAA}
+Where @code{AA} is the number of the last signal.
+Exceptions on the target are converted to the most similar Unix style
+signal number, like @code{SIGSEGV}. A sample response of this type would
+look like @code{$S05#}.
+
+@item TAAnn:XXXXXXXX;nn:XXXXXXXX;nn:XXXXXXXX;
+@code{AA} is the signal number.
+@code{nn} is the register number.
+@code{XXXXXXXX} is the register value.
+
+@item WAA
+The process exited, and @code{AA} is the exit status. This is only
+applicable for certains sorts of targets.
+
+@end itemize
+
+These are used in some GDB backends, but not all.
+
+@item write reg @code{Pnn=XXXXXXXX}
+Write register @code{nn} with value @code{XXXXXXXX}.
+
+returns @code{ACK} or @code{NAK}
+
+@item kill request k
+
+@item toggle debug d
+toggle debug flag (see 386 & 68k stubs)
+
+@item reset r
+reset -- see sparc stub.
+
+@item reserved @code{other}
+On other requests, the stub should ignore the request and send an empty
+response @code{$#<checksum>}. This way we can extend the protocol and GDB
+can tell whether the stub it is talking to uses the old or the new.
+
+@item search @code{tAA:PP,MM}
+Search backwards starting at address @code{AA} for a match with pattern
+PP and mask @code{MM}. @code{PP} and @code{MM} are 4 bytes.
+
+@item general query @code{qXXXX}
+Request info about XXXX.
+
+@item general set @code{QXXXX=yyyy}
+Set value of @code{XXXX} to @code{yyyy}.
+
+@item query sect offs @code{qOffsets}
+Get section offsets. Reply is @code{Text=xxx;Data=yyy;Bss=zzz}
+
+@item console output Otext
+Send text to stdout. The text gets display from the target side of the
+serial connection.
+
+@end table
+
+Responses can be run-length encoded to save space. A @code{*}means that
+the next character is an ASCII encoding giving a repeat count which
+stands for that many repetitions of the character preceding the @code{*}.
+The encoding is n+29, yielding a printable character where n >=3
+(which is where run length encoding starts to win). You can't use a
+value of where n >126 because it's only a two byte value. An example
+would be a @code{0*03} means the same thing as @code{0000}.
+
+@node Exception handler, ROM monitors, GNU remote protocol, GDB
+@section A linked in exception handler
+
+A @emph{GDB stub} consists of two parts, support for the exception
+handler, and the exception handler itself. The exception handler needs
+to communicate to GDB on the host whenever there is a breakpoint
+exception. When GDB starts a program running on the target, it's polling
+the serial port during execution looking for any debug packets. So when
+a breakpoint occurs, the exception handler needs to save state, and send
+a GDB remote protocol packet to GDB on the host. GDB takes any output
+that isn't a debug command packet and displays it in the command window.
+
+Support for the exception handler varies between processors, but the
+minimum supported functions are those needed by GDB. These are functions
+to support the reading and writing of registers, the reading and writing
+of memory, start execution at an address, single step, and last signal.
+Sometimes other functions for adjusting the baud rate, or resetting the
+hardware are implemented.
+
+Once GDB gets the command packet from the breakpoint, it will read a few
+registers and memory locations an then wait for the user. When the user
+types @code{run} or @code{continue} a @code{continue} command is issued
+to the backend, and control returns from the breakpoint routine to the
+application.
+
+@node ROM monitors, Other remote protocols, Exception handler, GDB
+@section Using a ROM monitor as a backend
+GDB also can mimic a human user and use a ROM monitors normal debug
+commands as a backend. This consists mostly of sending and parsing
+@code{ASCII} strings. All the ROM monitor interfaces share a common set
+of routines in @code{gdb/monitor.c}. This supports adding new ROM
+monitor interfaces by filling in a structure with the common commands
+GDB needs. GDb already supports several command ROM monitors, including
+Motorola's @code{Bug} monitor for their VME boards, and the Rom68k
+monitor by Integrated Systems, Inc. for various m68k based boards. GDB
+also supports the custom ROM monitors on the WinBond and Oki PA based
+targets. There is builtin support for loading files to ROM monitors
+specifically. GDB can convert a binary into an srecord and then load it
+as an ascii file, or using @code{xmodem}.

+
+ -lnnn specifies the length in bytes of the ISL code in

+
+ -ennn set the ISL entry point to nnn bytes from the

+ (decimal) bytes from the beginning of the ISL
+ object module.
+
+ -Knnn forces the directory start location to be the

+ *
+ * Description: low level support for gdb debugger. $
+ *
+ * Considerations: only works on target hardware $
+ *
+ * NOTES: See Below $
+ *
+ * To enable debugger support, two things need to happen.
+ *
+ * One, a call to set_debug_traps() is necessary in order to allow
+ * any breakpoints or error conditions to be properly intercepted and
+ * reported to gdb.
+ *
+ * Two, a breakpoint needs to be generated to begin communication.
+ * This is most easily accomplished by a call to breakpoint().
+ * breakpoint() simulates a breakpoint
+
+
+ *************
+ *
+ * The following gdb commands are supported:
+ *
+ * command function Return value
+ *
+ * g return the value of the CPU registers hex data or ENN
+ * G set the value of the CPU registers OK or ENN
+ *
+ * mAA..AA,LLLL Read LLLL bytes at address AA..AA hex data or ENN
+ * MAA..AA,LLLL: Write LLLL bytes at address AA.AA OK or ENN
+ *
+ * c Resume at current address SNN ( signal NN)
+ * cAA..AA Continue at address AA..AA SNN
+ *
+ * s Step one instruction SNN
+ * sAA..AA Step one instruction from AA..AA SNN
+ *
+ * k kill
+ *
+ * ? What was the last sigval ? SNN (signal NN)
+ *
+ * bBB..BB Set baud rate to BB..BB OK or BNN, then sets
+ * baud rate
+ *
+
+ ************
+ * All commands and responses are sent with a packet which includes a
+ * checksum. A packet consists of :
+ *
+ * $<packet info>#<checksum>.
+ *
+ * where
+ * <packet info> :: <characters representing the command or response>
+ * <checksum> :: < two hex digits computed as modulo 256 sum of <packetinfo>>
+ *
+ * When a packet is received, it is first acknowledged with either '+' or '-'.
+ * '+' indicates a successful transfer. '-' indicates a failed transfer.
+ *
+ * Example:
+ *
+ * Host: Reply:
+ * $m0,10#2a +$00010203040506070809101112131415#42

+ * Header: remcom.c,v 1.34 91/03/09 12:29:49 glenne Exp $
+ *
+ * Module name: remcom.c $
+ * Revision: 1.34 $
+ * Date: 91/03/09 12:29:49 $
+ * Contributor: Lake Stevens Instrument Division$
+ *
+ * Description: low level support for gdb debugger. $
+ *
+ * Considerations: only works on target hardware $
+ *
+ * Written by: Glenn Engel $
+ * ModuleState: Experimental $
+ *
+ * NOTES: See Below $
+ *
+ * To enable debugger support, two things need to happen. One, a
+ * call to set_debug_traps() is necessary in order to allow any breakpoints
+ * or error conditions to be properly intercepted and reported to gdb.
+ * Two, a breakpoint needs to be generated to begin communication. This
+ * is most easily accomplished by a call to breakpoint(). Breakpoint()
+ * simulates a breakpoint by executing a trap #1.
+ *
+ * Some explanation is probably necessary to explain how exceptions are
+ * handled. When an exception is encountered the 68000 pushes the current
+ * program counter and status register onto the supervisor stack and then
+ * transfers execution to a location specified in it's vector table.
+ * The handlers for the exception vectors are hardwired to jmp to an address
+ * given by the relation: (exception - 256) * 6. These are decending
+ * addresses starting from -6, -12, -18, ... By allowing 6 bytes for
+ * each entry, a jsr, jmp, bsr, ... can be used to enter the exception
+ * handler. Using a jsr to handle an exception has an added benefit of
+ * allowing a single handler to service several exceptions and use the
+ * return address as the key differentiation. The vector number can be
+ * computed from the return address by [ exception = (addr + 1530) / 6 ].
+ * The sole purpose of the routine _catchException is to compute the
+ * exception number and push it on the stack in place of the return address.
+ * The external function exceptionHandler() is
+ * used to attach a specific handler to a specific 68k exception.
+ * For 68020 machines, the ability to have a return address around just
+ * so the vector can be determined is not necessary because the '020 pushes an
+ * extra word onto the stack containing the vector offset
+ *
+ * Because gdb will sometimes write to the stack area to execute function
+ * calls, this program cannot rely on using the supervisor stack so it
+ * uses it's own stack area reserved in the int array remcomStack.
+ *
+ *************
+ *
+ * The following gdb commands are supported:
+ *
+ * command function Return value
+ *
+ * g return the value of the CPU registers hex data or ENN
+ * G set the value of the CPU registers OK or ENN
+ *
+ * mAA..AA,LLLL Read LLLL bytes at address AA..AA hex data or ENN
+ * MAA..AA,LLLL: Write LLLL bytes at address AA.AA OK or ENN
+ *
+ * c Resume at current address SNN ( signal NN)
+ * cAA..AA Continue at address AA..AA SNN
+ *
+ * s Step one instruction SNN
+ * sAA..AA Step one instruction from AA..AA SNN
+ *
+ * k kill
+ *
+ * ? What was the last sigval ? SNN (signal NN)
+ *
+ * All commands and responses are sent with a packet which includes a
+ * checksum. A packet consists of
+ *
+ * $<packet info>#<checksum>.
+ *
+ * where
+ * <packet info> :: <characters representing the command or response>
+ * <checksum> :: < two hex digits computed as modulo 256 sum of <packetinfo>>
+ *
+ * When a packet is received, it is first acknowledged with either '+' or '-'.
+ * '+' indicates a successful transfer. '-' indicates a failed transfer.
+ *
+ * Example:
+ *
+ * Host: Reply:
+ * $m0,10#2a +$00010203040506070809101112131415#42

+ *
+ * Module name: remcom.c $
+ * Revision: 1.34 $
+ * Date: 91/03/09 12:29:49 $
+ * Contributor: Lake Stevens Instrument Division$
+ *
+ * Description: low level support for gdb debugger. $
+ *
+ * Considerations: only works on target hardware $
+ *
+ * Written by: Glenn Engel $
+ * ModuleState: Experimental $
+ *
+ * NOTES: See Below $
+ *
+ * Modified for SPARC by Stu Grossman, Cygnus Support.
+ *
+ * This code has been extensively tested on the Fujitsu SPARClite demo board.
+ *
+ * To enable debugger support, two things need to happen. One, a
+ * call to set_debug_traps() is necessary in order to allow any breakpoints
+ * or error conditions to be properly intercepted and reported to gdb.
+ * Two, a breakpoint needs to be generated to begin communication. This
+ * is most easily accomplished by a call to breakpoint(). Breakpoint()
+ * simulates a breakpoint by executing a trap #1.
+ *
+ *************
+ *
+ * The following gdb commands are supported:
+ *
+ * command function Return value
+ *
+ * g return the value of the CPU registers hex data or ENN
+ * G set the value of the CPU registers OK or ENN
+ *
+ * mAA..AA,LLLL Read LLLL bytes at address AA..AA hex data or ENN
+ * MAA..AA,LLLL: Write LLLL bytes at address AA.AA OK or ENN
+ *
+ * c Resume at current address SNN ( signal NN)
+ * cAA..AA Continue at address AA..AA SNN
+ *
+ * s Step one instruction SNN
+ * sAA..AA Step one instruction from AA..AA SNN
+ *
+ * k kill
+ *
+ * ? What was the last sigval ? SNN (signal NN)
+ *
+ * bBB..BB Set baud rate to BB..BB OK or BNN, then sets
+ * baud rate
+ *
+ * All commands and responses are sent with a packet which includes a
+ * checksum. A packet consists of
+ *
+ * $<packet info>#<checksum>.
+ *
+ * where
+ * <packet info> :: <characters representing the command or response>
+ * <checksum> :: < two hex digits computed as modulo 256 sum of <packetinfo>>
+ *
+ * When a packet is received, it is first acknowledged with either '+' or '-'.
+ * '+' indicates a successful transfer. '-' indicates a failed transfer.
+ *
+ * Example:
+ *
+ * Host: Reply:
+ * $m0,10#2a +$00010203040506070809101112131415#42

+ # NOTE: The Vr4300 and Vr5432 *CANNOT* have any secondary cache.
+ # On those, SC (bit 17 of CONFIG register) is hard-wired to 1,
+ # except that email from Dennis_Han@el.nec.com says that old
+ # versions of the Vr5432 incorrectly hard-wired this bit to 0.
+ # The Vr5000 has an optional direct-mapped secondary cache,
+ # and the SC bit correctly indicates this.
+
+ # So, for the 4300 and 5432 we want to just
+ # flush the primary Data and Instruction caches.
+ # For the 5000 it is desired to flush the secondary cache too.
+ # There is an operation difference worth noting.
+ # The 4300 and 5000 primary caches use VA bit 14 to choose cache set,
+ # whereas 5432 primary caches use VA bit 0.
+
+ # This code interprets the relevant Config register bits as
+ # much as possible, except for the 5432.
+ # The code therefore has some portability.
+ # However, the associativity issues mean you should not just assume
+ # that this code works anywhere. Also, the secondary cache set
+ # size is hardwired, since the 5000 series does not define codes
+ # for variant sizes.
+

+
+Naming Conventions
+------------------
+ The basic naming convention for Unix machines is that
+ hppa1.1-hp-proelf- is prepended to the front of each tool
+ name. For DOS machines, the names are truncated to just the base
+ tool name, like GCC.
+
+Installation
+------------
+ For this beta release, there are three tar files on the tape. A
+ simple "tar xvf [device name]" will work. One of the tarfiles is
+ all the sources, the others are binaries. One set is for a HP-UX
+ host, and the other set is for a sun4 host.
+
+ First, make a directory called /usr/cygnus/beta-941019. Cd into
+ this directory and type the tar command to extract the three tar
+ files. Once the tar files are off the tape, you can uncompress
+ and extract them. Typically, once they are installed, it's common
+ practice to make a symbolic link so the path
+ /usr/cygnus/beta-941019 works regardless which host. The actual
+ binaries are in /usr/cygnus/beta-941019/$host/bin, where host is
+ the configuration string for this machine.
+
+
+ WinBond W89k board
+ ..................
+Downloading
+-----------
+ To download type the "U" command to the ROM monitor. This will
+ load to the address as specified in the srecord. This address is
+ 0x100000.
+
+To compile
+----------
+ Use these arguments on the command line for either the linker or
+ the compiler:
+
+ -Tw89k.ld -Ttext 100000
+
+To execute
+----------
+ Type a "g = 100000" at thr ROM monitor after downloading to the
+ target. After downloading, PC will be set to the correct address,
+ but this command will *always* restart the execution from the
+ beginning.
+
+To debug
+--------
+ To connect GDB to the target, use the "target w89k [devicename]".
+
+ Oki OP50N board
+ ...............
+
+Downloading
+-----------
+ To download, type "r 0" to the ROM monitor. The 0 is cause the
+ monitor wants to offset the address in the srecord to 0x40000. The
+ problem is that it doesn't relocate data right. So, we set the
+ address for .text and .data to 0x40000, and we don't want any
+ offset.
+
+To compile
+----------
+ Use these arguments on the command line for either the linker or
+ the compiler:
+
+ -Top50n.ld -Ttext 40000
+
+ To execute
+----------
+ Type a "g 40000" at thr ROM monitor after downloading to the
+ target. After downloading, PC will be set to the correct address,
+ but this command will *always* restart the execution from the
+ beginning
+
+To debug
+--------
+ To connect GDB to the target, use the "target op50n [devicename]".

+! This file supports:
+!
+! - both 32bit pointer and 64bit pointer environments (at compile time)
+! - an imposed stack bias (of 2047) (at run time)
+! - medium/low and medium/anywhere code models (at run time)
+
+! Initial stack setup:
+!
+! bottom of stack (higher memory address)
+! ...
+! text of environment strings
+! text of argument strings
+! envp[envc] = 0 (4/8 bytes)
+! ...
+! env[0] (4/8 bytes)
+! argv[argc] = 0 (4/8 bytes)
+! ...
+! argv[0] (4/8 bytes)
+! argc (4/8 bytes)
+! register save area (64 bits by 16 registers = 128 bytes)
+! top of stack (%sp)
+
+! Stack Bias:
+!
+! It is the responsibility of the o/s to set this up.
+! We handle both a 0 and 2047 value for the stack bias.
+
+! Medium/Anywhere code model support:
+!
+! In this model %g4 points to the start of the data segment.
+! The text segment can go anywhere, but %g4 points to the *data* segment.
+! It is up to the compiler/linker to get this right.
+!
+! Since this model is statically linked the start of the data segment
+! is known at link time. Eg:
+!
+! sethi %hh(data_start), %g1
+! sethi %lm(data_start), %g4
+! or %g1, %hm(data_start), %g1
+! or %g4, %lo(data_start), %g4
+! sllx %g1, 32, %g1
+! or %g4, %g1, %g4

+ * Header: remcom.c,v 1.34 91/03/09 12:29:49 glenne Exp $
+ *
+ * Module name: remcom.c $
+ * Revision: 1.34 $
+ * Date: 91/03/09 12:29:49 $
+ * Contributor: Lake Stevens Instrument Division$
+ *
+ * Description: low level support for gdb debugger. $
+ *
+ * Considerations: only works on target hardware $
+ *
+ * Written by: Glenn Engel $
+ * ModuleState: Experimental $
+ *
+ * NOTES: See Below $
+ *
+ * Modified for SPARC by Stu Grossman, Cygnus Support.
+ *
+ * This code has been extensively tested on the Fujitsu SPARClite demo board.
+ *
+ * To enable debugger support, two things need to happen. One, a
+ * call to set_debug_traps() is necessary in order to allow any breakpoints
+ * or error conditions to be properly intercepted and reported to gdb.
+ * Two, a breakpoint needs to be generated to begin communication. This
+ * is most easily accomplished by a call to breakpoint(). Breakpoint()
+ * simulates a breakpoint by executing a trap #1.
+ *
+ *************
+ *
+ * The following gdb commands are supported:
+ *
+ * command function Return value
+ *
+ * g return the value of the CPU registers hex data or ENN
+ * G set the value of the CPU registers OK or ENN
+ *
+ * mAA..AA,LLLL Read LLLL bytes at address AA..AA hex data or ENN
+ * MAA..AA,LLLL: Write LLLL bytes at address AA.AA OK or ENN
+ *
+ * c Resume at current address SNN ( signal NN)
+ * cAA..AA Continue at address AA..AA SNN
+ *
+ * s Step one instruction SNN
+ * sAA..AA Step one instruction from AA..AA SNN
+ *
+ * k kill
+ *
+ * ? What was the last sigval ? SNN (signal NN)
+ *
+ * bBB..BB Set baud rate to BB..BB OK or BNN, then sets
+ * baud rate
+ *
+ * All commands and responses are sent with a packet which includes a
+ * checksum. A packet consists of
+ *
+ * $<packet info>#<checksum>.
+ *
+ * where
+ * <packet info> :: <characters representing the command or response>
+ * <checksum> :: < two hex digits computed as modulo 256 sum of <packetinfo>>
+ *
+ * When a packet is received, it is first acknowledged with either '+' or '-'.
+ * '+' indicates a successful transfer. '-' indicates a failed transfer.
+ *
+ * Example:
+ *
+ * Host: Reply:
+ * $m0,10#2a +$00010203040506070809101112131415#42

+ *
+ * Module name: remcom.c $
+ * Revision: 1.34 $
+ * Date: 91/03/09 12:29:49 $
+ * Contributor: Lake Stevens Instrument Division$
+ *
+ * Description: low level support for gdb debugger. $
+ *
+ * Considerations: only works on target hardware $
+ *
+ * Written by: Glenn Engel $
+ * ModuleState: Experimental $
+ *
+ * NOTES: See Below $
+ *
+ * Modified for SPARC by Stu Grossman, Cygnus Support.
+ * Based on sparc-stub.c, it's modified for SPARClite Debug Unit hardware
+ * breakpoint support to create sparclite-stub.c, by Kung Hsu, Cygnus Support.
+ *
+ * This code has been extensively tested on the Fujitsu SPARClite demo board.
+ *
+ * To enable debugger support, two things need to happen. One, a
+ * call to set_debug_traps() is necessary in order to allow any breakpoints
+ * or error conditions to be properly intercepted and reported to gdb.
+ * Two, a breakpoint needs to be generated to begin communication. This
+ * is most easily accomplished by a call to breakpoint(). Breakpoint()
+ * simulates a breakpoint by executing a trap #1.
+ *
+ *************
+ *
+ * The following gdb commands are supported:
+ *
+ * command function Return value
+ *
+ * g return the value of the CPU registers hex data or ENN
+ * G set the value of the CPU registers OK or ENN
+ *
+ * mAA..AA,LLLL Read LLLL bytes at address AA..AA hex data or ENN
+ * MAA..AA,LLLL: Write LLLL bytes at address AA.AA OK or ENN
+ *
+ * c Resume at current address SNN ( signal NN)
+ * cAA..AA Continue at address AA..AA SNN
+ *
+ * s Step one instruction SNN
+ * sAA..AA Step one instruction from AA..AA SNN
+ *
+ * k kill
+ *
+ * ? What was the last sigval ? SNN (signal NN)
+ *
+ * bBB..BB Set baud rate to BB..BB OK or BNN, then sets
+ * baud rate
+ *
+ * All commands and responses are sent with a packet which includes a
+ * checksum. A packet consists of
+ *
+ * $<packet info>#<checksum>.
+ *
+ * where
+ * <packet info> :: <characters representing the command or response>
+ * <checksum> :: < two hex digits computed as modulo 256 sum of <packetinfo>>
+ *
+ * When a packet is received, it is first acknowledged with either '+' or '-'.
+ * '+' indicates a successful transfer. '-' indicates a failed transfer.
+ *
+ * Example:
+ *
+ * Host: Reply:
+ * $m0,10#2a +$00010203040506070809101112131415#42

+ *
+ * Module name: remcom.c $
+ * Revision: 1.34 $
+ * Date: 91/03/09 12:29:49 $
+ * Contributor: Lake Stevens Instrument Division$
+ *
+ * Description: low level support for gdb debugger. $
+ *
+ * Considerations: only works on target hardware $
+ *
+ * Written by: Glenn Engel $
+ * ModuleState: Experimental $
+ *
+ * NOTES: See Below $
+ *
+ * Modified for SPARC by Stu Grossman, Cygnus Support.
+ * Based on sparc-stub.c, it's modified for SPARClite Debug Unit hardware
+ * breakpoint support to create sparclite-stub.c, by Kung Hsu, Cygnus Support.
+ *
+ * This code has been extensively tested on the Fujitsu SPARClite demo board.
+ *
+ * To enable debugger support, two things need to happen. One, a
+ * call to set_debug_traps() is necessary in order to allow any breakpoints
+ * or error conditions to be properly intercepted and reported to gdb.
+ * Two, a breakpoint needs to be generated to begin communication. This
+ * is most easily accomplished by a call to breakpoint(). Breakpoint()
+ * simulates a breakpoint by executing a trap #1.
+ *
+ *************
+ *
+ * The following gdb commands are supported:
+ *
+ * command function Return value
+ *
+ * g return the value of the CPU registers hex data or ENN
+ * G set the value of the CPU registers OK or ENN
+ * P set the value of a single CPU register OK or P01 (???)
+ *
+ * mAA..AA,LLLL Read LLLL bytes at address AA..AA hex data or ENN
+ * MAA..AA,LLLL: Write LLLL bytes at address AA.AA OK or ENN
+ *
+ * c Resume at current address SNN ( signal NN)
+ * cAA..AA Continue at address AA..AA SNN
+ *
+ * s Step one instruction SNN
+ * sAA..AA Step one instruction from AA..AA SNN
+ *
+ * k kill
+ *
+ * ? What was the last sigval ? SNN (signal NN)
+ *
+ * bBB..BB Set baud rate to BB..BB OK or BNN, then sets
+ * baud rate
+ *
+ * All commands and responses are sent with a packet which includes a
+ * checksum. A packet consists of
+ *
+ * $<packet info>#<checksum>.
+ *
+ * where
+ * <packet info> :: <characters representing the command or response>
+ * <checksum> :: <two hex digits computed as modulo 256 sum of <packetinfo>>
+ *
+ * When a packet is received, it is first acknowledged with either '+' or '-'.
+ * '+' indicates a successful transfer. '-' indicates a failed transfer.
+ *
+ * Example:
+ *
+ * Host: Reply:
+ * $m0,10#2a +$00010203040506070809101112131415#42
