33 A DLL contains an export table which contains the information
34 which the runtime loader needs to tie up references from a
37 The export table is generated by this program by reading
38 in a .DEF file or scanning the .a and .o files which will be in the
39 DLL. A .o file can contain information in special ".drectve" sections
40 with export information.
42 A DEF file contains any number of the following commands:
45 NAME <name> [ , <base> ]
46 The result is going to be <name>.EXE
48 LIBRARY <name> [ , <base> ]
49 The result is going to be <name>.DLL
51 EXPORTS ( ( ( <name1> [ = <name2> ] )
52 | ( <name1> = <module-name> . <external-name>))
53 [ @ <integer> ] [ NONAME ] [CONSTANT] [DATA] ) *
54 Declares name1 as an exported symbol from the
55 DLL, with optional ordinal number <integer>.
56 Or declares name1 as an alias (forward) of the function <external-name>
57 in the DLL <module-name>.
59 IMPORTS ( ( <internal-name> = <module-name> . <integer> )
60 | ( [ <internal-name> = ] <module-name> . <external-name> )) *
61 Declares that <external-name> or the exported function whoes ordinal number
62 is <integer> is to be imported from the file <module-name>. If
63 <internal-name> is specified then this is the name that the imported
64 function will be refered to in the body of the DLL.
67 Puts <string> into output .exp file in the .rdata section
69 [STACKSIZE|HEAPSIZE] <number-reserve> [ , <number-commit> ]
70 Generates --stack|--heap <number-reserve>,<number-commit>
71 in the output .drectve section. The linker will
72 see this and act upon it.
75 SECTIONS ( <sectionname> <attr>+ )*
76 <attr> = READ | WRITE | EXECUTE | SHARED
77 Generates --attr <sectionname> <attr> in the output
78 .drectve section. The linker will see this and act
82 A -export:<name> in a .drectve section in an input .o or .a
83 file to this program is equivalent to a EXPORTS <name>
88 The program generates output files with the prefix supplied
89 on the command line, or in the def file, or taken from the first
92 The .exp.s file contains the information necessary to export
93 the routines in the DLL. The .lib.s file contains the information
94 necessary to use the DLL's routines from a referencing program.

201 /* .idata section description
203 The .idata section is the import table. It is a collection of several
204 subsections used to keep the pieces for each dll together: .idata$[234567].
205 IE: Each dll's .idata$2's are catenated together, each .idata$3's, etc.
207 .idata$2 = Import Directory Table
208 = array of IMAGE_IMPORT_DESCRIPTOR's.
210 DWORD Import Lookup Table; - pointer to .idata$4
211 DWORD TimeDateStamp; - currently always 0
212 DWORD ForwarderChain; - currently always 0
213 DWORD Name; - pointer to dll's name
214 PIMAGE_THUNK_DATA FirstThunk; - pointer to .idata$5
216 .idata$3 = null terminating entry for .idata$2.
218 .idata$4 = Import Lookup Table
219 = array of array of pointers to hint name table.
220 There is one for each dll being imported from, and each dll's set is
221 terminated by a trailing NULL.
223 .idata$5 = Import Address Table
224 = array of array of pointers to hint name table.
225 There is one for each dll being imported from, and each dll's set is
226 terminated by a trailing NULL.
227 Initially, this table is identical to the Import Lookup Table. However,
228 at load time, the loader overwrites the entries with the address of the
231 .idata$6 = Hint Name Table
232 = Array of { short, asciz } entries, one for each imported function.
233 The `short' is the function's ordinal number.
235 .idata$7 = dll name (eg: "kernel32.dll"). (.idata$6 for ppc)

315 When IMPORT declarations are encountered in a .def file the
316 function import information is stored in a structure referenced by

318 containing the names of the dll files each function is imported
319 from and a linked list of functions being imported from that dll
320 file. This roughly parallels the structure of the .idata section
321 in the PE object file.

1045 MODULE - the name of the dll, possibly sans extension (ie, '.dll').
1046 DLLEXT - the extension of the dll, if present, NULL if not present.
1047 ENTRY - the name of the function in the dll, if present, or NULL.
1048 ORD_VAL - the numerical tag of the function in the dll, if present,

3456 deduce_name("as") uses the following search order:
3458 /usr/local/bin/i586-cygwin32-as
3462 If there's an EXECUTABLE_SUFFIX, it'll use that as well; for each
3463 name, it'll try without and then with EXECUTABLE_SUFFIX.
3465 Given, argv[0] = i586-cygwin32-dlltool, it will not even try "as"
3466 as the fallback, but rather return i586-cygwin32-as.
3468 Oh, and given, argv[0] = dlltool, it'll return "as".
