+/* This header defines three types of macros:
+
+ - atomic arithmetic and logic operation on memory. They all
+ have the prefix "atomic_".
+
+ - conditionally atomic operations of the same kinds. These
+ always behave identical but can be faster when atomicity
+ is not really needed since only one thread has access to
+ the memory location. In that case the code is slower in
+ the multi-thread case. The interfaces have the prefix
+ "catomic_".
+
+ - support functions like barriers. They also have the preifx
+ "atomic_".
+
+ Architectures must provide a few lowlevel macros (the compare
+ and exchange definitions). All others are optional. They
+ should only be provided if the architecture has specific
+ support for the operation.
+
+ As <atomic.h> macros are usually heavily nested and often use local
+ variables to make sure side-effects are evaluated properly, use for
+ macro local variables a per-macro unique prefix. This file uses
+ __atgN_ prefix where N is different in each macro. */

+
+ 2 * xchg is more expensive than pushl + movl + popl
+
+ Beside this a neat trick is used. The calling conventions for Linux
+ tell that among the registers used for parameters %ecx and %edx need
+ not be saved. Beside this we may clobber this registers even when
+ they are not used for parameter passing.
+
+ As a result one can see below that we save the content of the %ebx
+ register in the %edx register when we have less than 3 arguments
+ (2 * movl is less expensive than pushl + popl).
+
+ Second unlike for the other registers we don't save the content of
+ %ecx and %edx when we have more than 1 and 2 registers resp.
+
+ The code below might look a bit long but we have to take care for
+ the pipelined processors (i586). Here the `pushl' and `popl'
+ instructions are marked as NP (not pairable) but the exception is
+ two consecutive of these instruction. This gives no penalty on

+The base NPTL code for uClibc is from the glibc project located at
+<http://sourceware.org/glibc/>. The starting version was the HEAD of
+the glibc CVS repository dated 2005-05-06. Important changes from
+glibc will continue to be brought in as necessary until the version
+for uClibc is standing on its own. All of the files were originally
+brought over verbatim with no modifications. Obviously, these will
+undergo any necessary changes needed for integration into uClibc.
+Additionally (or subtractingly), the files and directories below
+were removed and not imported.

--- /dev/null
+- we should probably extend pthread_mutexattr_t with a field to create a
+ single linked list of all instances. This requires changing the
+ pthread_mutexattr_* functions.
+
+
+- a new attribute for mutexes: number of times we spin before calling
+sys_futex
+
+- for adaptive mutexes: when releasing, determine whether somebody spins.
+If yes, for a short time release lock. If someone else locks no wakeup
+syscall needed.
+
+
+
+- test with threaded process terminating and semadj (?) being applied
+ only after all threads are gone
+
+
+
+- semaphore changes:
+
+ - sem_post should only wake one thread and only when the state of
+ the semaphore changed from 0 to 1
+
+ this also requires that sem_wait and sem_timedwait don't drop the
+ post if they get canceled.
+
+ - possibly add counter field. This requires reviving the
+ differences between old and new semaphose funtions. The old ones
+ stay as they are now. The new once can use an additional field
+ wich is the counter for the number of waiters
--- /dev/null
+- setuid/setgid must effect process
+ + test syscalls (getuid) afterwards
+ + test core file content
+
+ + use UID/GID in access(2), chmod(2), chown(2), link(2)
+
+- nice level is process property
+
+- rlimit should be process-wide and SIGXCPU should be sent if all threads
+ together exceed the limit
+
+- getrusage() must return resource utilization for the process
+
+
+
+The following are possible optimizations and in no way required:
+
+
+- the scheduler should be thread group-aware, i.e., it has to give time to
+ the thread group not proportional to the number of threads.

+ requirements for the data at the positions *in the file*, though.
+ I.e, it is not simply possible to allocate a block with the size
+ of the TLS program header entry. The data is layed out assuming
+ that the first byte of the TLS block fulfills
+
+ p_vaddr mod p_align == &TLS_BLOCK mod p_align
+
+ This means we have to add artificial padding at the beginning of
+ the TLS block. These bytes are never used for the TLS data in
+ this module but the first byte allocated must be aligned
+ according to mod p_align == 0 so that the first byte of the TLS
+ block is aligned according to p_vaddr mod p_align. This is ugly
+ and the linker can help by computing the offsets in the TLS block
+ assuming the first byte of the TLS block is aligned according to
+ p_align.
+
+ The extra space which might be allocated before the first byte of
+ the TLS block need not go unused. The code below tries to use
+ that memory for the next TLS block. This can work if the total
+ memory requirement for the next TLS block is smaller than the

+These tests were imported from 'glibc/elf' and are responsible for testing
+the TLS functionality of the dynamic loader. The file 'tls-macros-mips.h'
+is a copy of 'glibc/sysdeps/mips/tls-macros.h'. Dependency and link orders
+are critical and should NOT be changed. Even if you think you know what
+you are doing, do not touch the Makefile without posting to the uClibc
