* optimize contended normal mutex case; add int compare-and-swap atomicRich Felker2011-03-171-0/+7
|
* match dimensions so we can use all slots without invoking OOB-array-accessRich Felker2011-03-111-5/+5
|
* fix missing ENOTSUP error codeRich Felker2011-03-111-0/+1
|
* make sigaltstack work (missing macros in signal.h, error conditions)Rich Felker2011-03-101-0/+2
|
* resolve some header namespace non-issuesRich Felker2011-02-201-1/+0
| | | | | after re-reading 2.2.2 of POSIX 2008, all of these are in the correct reserved namespaces and do not need protection.
* fill in some missing siginfo stuff in signal.hRich Felker2011-02-201-5/+56
|
* add missing WIFCONTINUED macro and improve WIFSIGNALEDRich Felker2011-02-191-1/+2
|
* support the ugly and deprecated ucontext and sigcontext header stuff...Rich Felker2011-02-181-0/+34
| | | | | | | | | | | | | | only the structures, not the functions from ucontext.h, are supported at this point. the main goal of this commit is to make modern gcc with dwarf2 unwinding build without errors. honestly, it probably doesn't matter how we define these as long as they have members with the right names to prevent errors while compiling libgcc. the only time they will be used is for propagating exceptions across signal-handler boundaries, which invokes undefined behavior anyway. but as-is, they're probably correct and may be useful to various low-level applications dealing with virtualization, jit code generation, and so on...
* reorganize pthread data structures and move the definitions to alltypes.hRich Felker2011-02-171-0/+15
| | | | | | | | this allows sys/types.h to provide the pthread types, as required by POSIX. this design also facilitates forcing ABI-compatible sizes in the arch-specific alltypes.h, while eliminating the need for developers changing the internals of the pthread types to poke around with arch-specific headers they may not be able to test.
* move stdio stuff that's not arch-specific out of bitsRich Felker2011-02-151-17/+0
|
* fix the types of some integer constant limits in headersRich Felker2011-02-151-2/+2
|
* remove standalone syscall cruftRich Felker2011-02-151-11/+1
| | | | | | | | | | | this was originally written for an early draft of the library where non-standard functions would reside in a static library separate from the shared libc.so, which would implement a pure standard. the idea was not to depend on an implementation-dependent __syscall_ret function in the main libc. but it turned out to be better to put everything in a single library for both static and dynamic linking uses, and thus the (incomplete) remnants of this feature were just enlarging the source and binary.
* fix some type leakage (timer_t) from x86_64 commitRich Felker2011-02-151-1/+1
|
* yet another ugly legacy syscall rename...Rich Felker2011-02-151-0/+5
|
* fix getrlimit handling on 32-bit systems, and ease porting to 64-bitRich Felker2011-02-151-0/+2
|
* split off arch-specific stdarg.h stuffRich Felker2011-02-151-0/+9
|
* cleanup socketcall syscall interface to ease porting to sane(r) archsRich Felker2011-02-152-0/+28
|
* finish moving 32-bit-specific junk out of source files.Rich Felker2011-02-151-0/+23
|
* move arch-specific internal headers into placeRich Felker2011-02-152-0/+610
|
* finish unifying thread register handling in preparation for portingRich Felker2011-02-151-0/+6
|
* preparing build system to handle ports - step 1Rich Felker2011-02-1528-0/+1497
