2009-07-23create real common vfork() functionMike Frysinger
Rather than force people to always implement their own vfork(), have the default implementation be sane. For now, only the Blackfin port uses the new code. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-07-22Blackfin: no need to load P5 for shared FLATJie Zhang
The register is already loaded for us upon entry by the kernel. Signed-off-by: Jie Zhang <jie.zhang@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>

Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-07-22add hidden aliases for openat funcsMike Frysinger
openat64() uses openat(), so we need hidden aliases for it. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-07-22add hidden aliases for ntoh/hton functionsMike Frysinger
Sometimes references for these functions show up (like when debugging is enabled), so add hidden aliases for them if needed. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-07-21byteswap: unify common definitionsMike Frysinger
The majority of the byteswap functions are the same across all arches, so setup a common header to provide definitions if they don't exist. This allows arches to override only the ones they actually want to implement with inline assembly. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-07-21s/UCLIBC_INTERNAL/_LIBC/gDenys Vlasenko
Undo my old mistake. I added UCLIBC_INTERNAL define, but later I realized _LIBC is doing exactly the same thing. This change converts all usages of UCLIBC_INTERNAL to _LIBC, removing all instances of UCLIBC_INTERNAL. Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2009-07-20avr32/microblaze/vax: punt local byteswap.hMike Frysinger
These arches are generic C implementations of the byteswap functions, so rather than keep a useless local copy, use the common C one. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-07-20syscall: convert cris/hppa to common syscallsMike Frysinger
The cris/hppa code appears to be easy to convert, so go ahead and do it for them. Build tested only. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-07-20some ports define ENOTSUPMike Frysinger
A port or two (like hppa) does define ENOTSUP, so don't assume that everyone needs this fallback define. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-07-20INLINE_SYSCALL_NCS: scope out local vars to avoid conflictsMike Frysinger
The INLINE_SYSCALL_NCS() macro was using "res" and "err" as local variable names, but this caused conflicts with some code (like clock_getres) whose arguments were named the same. libc/sysdeps/linux/common/clock_getres.c: In function 'clock_getres': libc/sysdeps/linux/common/clock_getres.c:15: warning: 'res' is used uninitialized in this function Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-07-20fix building for systems w/out ldso supportMike Frysinger
If an arch (like alpha and others) have no ldso support at all, then there is no point in attempting to walk loaded modules in the dl-* helper funcs. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-07-20alpha: fix building with no asm/elf.hMike Frysinger
The latest sanitized linux kernel headers no longer export asm/elf.h, so do not rely on it anymore. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-07-20fdatasync: handle latest alpha syscallsMike Frysinger
The latest alpha Linux kernel defines __NR_fdatasync like everyone else and deprecates the older __NR_osf_fdatasync, so support that setup. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-07-20alpha/sigprocmask: fix implicit memset() prototypeMike Frysinger
Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-07-20first pass at implementing *at funcsMike Frysinger
Tested basic functionality with coreutils and things seem to work. At least gives us a basis to jump from. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-07-20dirent: push dirent type to prototypesMike Frysinger
This syncs the dirent related functions with the glibc behavior -- rather than take void pointers everywhere, make the struct dirent pointers explicit in the API. After all, the functions themselves will cast the pointers to a dirent structure, so if it isn't as expected, people will crash. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-07-20regex: convert #if to #ifdefMike Frysinger
Avoid gcc warnings about #if statements with defines that aren't defined. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2009-07-14Fix ARM syscall argument loading.Joseph Myers
This patch is a uClibc equivalent of <http://sourceware.org/ml/libc-ports/2008-11/msg00006.html>, to compute all syscall arguments on ARM in temporary variables before loading them into register variables. The principle is as for that glibc patch; the problem I actually observed was a GCC internal compiler error building ld.so for Thumb-2. Signed-off-by: Joseph Myers <joseph@codesourcery.com>

2009-07-09syscall: unify part 2: NCS varietyMike Frysinger
Declare common NCS (non-constant syscall) variants and convert the existing ports over to this. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-07-09sh: Change __HAVE_SHARED__ to __PIC__Peter Griffin
Generate PIC relocations when __PIC__ is defined rather than __HAVE_SHARED__ (like other architectures). Signed-off-by: Peter Griffin <pgriffin@mpc-data.co.uk> Signed-off-by: Carmelo Amoroso <carmelo.amoroso@st.com>
2009-07-08drop missing {INLINE,INTERNAL}_SYSCALL fallback logicMike Frysinger
Ports missing INLINE_SYSCALL() support need to get fixed, so drop the cruft keeping them alive since it no longer works with the unification. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-07-08syscall: unify common syscall definesMike Frysinger
Unify all the common syscall defines in syscalls-common.h and scrub all the duplicated code from relevant ports. This should also make converting existing ports to INLINE_SYSCALL() much easier as they don't have to get lost in all the unrelated noise, as well as creating new ports.

2009-07-05Avoid warnings about shifting more bits than we haveRon
The test here is a constant expression and will compile out. For platforms that don't need the shift the code gets slightly smaller and simpler, for those that do the result is unchanged. Signed-off-by: Ron Lee <ron@debian.org> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-07-05Check #if feature test macros are defined where they may not beRon
Once again all of these reduce the noise from gcc-4.4. Replaces a few more (USE_TLS && HAVE___THREAD) with USE___THREAD while we need to mess with them for this anyhow. Signed-off-by: Ron Lee <ron@debian.org> Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2009-07-03i386: store errno value before using __set_errno()Ingo van Lil
The __syscall_error() function stores the errno value in the edx register before invoking the __set_errno() macro. When using the pthread library this macro calls thread_self() to determine the errno location, which might clobber the edx register. The errno value must be stored in a "real" variable so the compiler can take care of saving/restoring it if necessary.

2009-07-01Correct ARM memcpy comments.Joseph Myers
The comments on register usage in ARM memcpy had dest and src the wrong way round; this patch (originally from Mark Shinwell) corrects this and adds a note on the return value. Signed-off-by: Joseph Myers <joseph@codesourcery.com>
2009-06-30Fix Thumb-2 setjmp.Joseph Myers
Many Thumb-2 instructions cannot use sp or pc as operands, and the assembler now diagnoses these. setjmp had one such instruction, movs; this patch changes it to mov. Signed-off-by: Joseph Myers <joseph@codesourcery.com>
2009-06-30Fix Thumb-2 memcpy.Joseph Myers
When an IT block was changed from having two instructions to having one, the IT instruction at the start of the block was not updated, causing memcpy to fail to assemble for Thumb-2; this patch makes the obvious fix. Signed-off-by: Joseph Myers <joseph@codesourcery.com>
2009-06-28Add missing CLIBABI variables __aeabi_stdin, __aeabi_stdout, __aeabi_stderr.Joseph Myers
The ARM EABI has a document CLIBABI specifying various __aeabi_* functions and variables to be provided for the use of portable objects that can be linked with different EABI-conforming C libraries. __aeabi_stdin, __aeabi_stdout and __aeabi_stderr were missing in uClibc; this patch (originally from Nathan Froyd and for glibc) adds them. Signed-off-by: Joseph Myers <joseph@codesourcery.com>
2009-06-28wchar: fix inverted parameters in error messageAndré Goddard Rosa
The error message should output "fromcode -> tocode" rather than "tocode -> fromcode". Seems to be a typo due to the order of the func called: iconv_t iconv_open(const char *tocode, const char *fromcode); Signed-off-by: André Goddard Rosa <andre.goddard@gmail.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-06-28libc.so: include all output formats in linker scriptSteve Bennett
Rather than ripping out the default output format from the linker, include the big/little endian alternatives for the people who link with bi-endian toolchains.

2009-05-27waitid: linux ABI takes 5 args, not 4Mike Frysinger
The POSIX waitid() takes 4 args, but the Linux one takes 5 args, so make sure we stuff the 5th arg with a NULL. Otherwise garbage gets randomly passed up and considering this is a pointer, that's baaaad. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
