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
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>
2009-07-20add 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().

2009-07-20fix typo in frv endian commentMike Frysinger

2009-07-20relocate i386 string.h to i386-specific dirMike Frysinger
Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-07-20start ignoring include/ symlinksMike Frysinger
Signed-off-by: Mike Frysinger <vapier@gentoo.org>
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>
2009-07-20ppoll: switch to INLINE_SYSCALL() to match glibcMike Frysinger

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>

2009-07-09syscall(): create a common version based on INLINE_SYSCALL_NCS()Mike Frysinger
Signed-off-by: Mike Frysinger <vapier@gentoo.org>
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>
2009-07-09MAKEALL: expand cross-compiler arch searchMike Frysinger
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. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2009-07-05Avoid type-punned pointers that break strict-aliasingRon
Signed-off-by: Ron Lee <ron@debian.org> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
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>
2009-07-05Don't shadow the chroot globalRon

Signed-off-by: Ron Lee <ron@debian.org> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-07-05Don't shadow the err() function with a local varRon
gcc-4.4 barks about that. Signed-off-by: Ron Lee <ron@debian.org> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-07-05Add a few missing includesRon
elf.h needs __BYTE_ORDER, and s_scalbn.c needs {LONG,INT}_MAX. shm.c complains about no prototypes for shm_{open,unlink} without its header. 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>
2009-07-05Provide token prototypes for functions that are external but have no headerRon
This cuts down on a lot of noise from gcc-4.4 Signed-off-by: Ron Lee <ron@debian.org> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-07-05Make more utility functions staticRon
This keeps gcc-4.4 from nagging that they have no prototypes. Signed-off-by: Ron Lee <ron@debian.org> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-07-05Add noreturn attributes to some functions that won't ever do soRon
usage() is also made static in answer to warnings about no prototype. In __pthread_manager_event() we also have to drop the return statement, else gcc will in turn complain about a non-returning function having one. Signed-off-by: Ron Lee <ron@debian.org> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-07-05Move extern prototype out of function scopeRon
gcc-4.4 now barks about this, so appease it. Signed-off-by: Ron Lee <ron@debian.org> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-07-05Add some missing printf/scanf format attributesRon
The gcc-4.4 documentation still suggests that the compiler will automatically do format checking for the standard format function prototypes, but it is now also barking warnings suggesting that we add them for this lot too. So added. Signed-off-by: Ron Lee <ron@debian.org> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-07-05use -isystem with gcc pathsMike Frysinger
Use -isystem to include gcc header paths rather than -I as these are system paths, not uClibc specific paths. 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.
