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>

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>
2009-07-21linuxthreads.old: fix crash in debug codeMike Frysinger
If pthread_join() is called and there is nothing to join, then the debug code will attempt to dereference a NULL pointer. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-07-21libpthread: add format attribute to __pthread_message()Mike Frysinger
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>
2009-07-20MAKEALL: find kernel headers betterMike Frysinger
Work with pre-sysroot compilers that have kernel headers available in the standard location, and let people force the location manually. 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>
2009-07-20linuxthreads.old: extend workaround for asm rename warningsMike Frysinger
The libc_pthread_init.c needs the include workaround like forward.c, and forward.c needs more includes now. 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>
2009-07-20sync a few headers with glibc (no functional changes)Mike Frysinger
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>
2009-07-20string: only include inline-asm if UCLIBC_HAS_STRING_ARCH_OPTMike Frysinger

Avoid gcc warnings about #if statements with defines that aren't defined. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-07-20add a wchar.h stubMike Frysinger
The basic C standard requires a few wchar types, so provide those even when wchar support is disabled. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-07-20mknod: convert to INLINE_SYSCALL() to sync with glibcMike Frysinger
Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-07-20note that we do not want hidden malloc aliasesMike Frysinger
We want to let malloc() and friends be overridable at runtime so that apps can insert their own implementation (think debugging, specialized setups, etc...). That means that C library functions that return allocated memory have to go through the normal malloc() symbol as well as the external code is the one who will be calling free().

2009-07-20unifdef: implement err.h funcs locallyMike Frysinger
Since the err.h functions are optional in uClibc, make sure we can rebuild ourselves if support is disabled. URL: https://bugs.busybox.net/show_bug.cgi?id=257 Reported-by: Michael Deutschmann <michael@talamasca.ocis.net> Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2009-07-15install_headers: convert header removal to Kbuild styleMike Frysinger
Convert the large if...$(RM)...endif style to standard Kbuild foo-$(...) += style to make the list much easier to review and update. This is largely a style change, but in the process, these two headers are added to the "always remove" list: tls.h and uClibc_errno.h Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-07-15use -EB/-EL for all targetsMike Frysinger
These are common linker options rather than target specific ones, so they should be safe to use for all targets. 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>

2009-07-08drop 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.
