2009-07-22Blackfin: fix generation of Scrt1.o for FDPICJie Zhang
Signed-off-by: Jie Zhang <jie.zhang@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-07-22Blackfin: unify FDPIC/FLAT versions of cloneMike Frysinger
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>
2009-07-21byteswap: 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>
2009-07-20It fixes the following warnings seen on mips build.Khem Raj
libc/sysdeps/linux/mips/clone.S: Assembler messages: libc/sysdeps/linux/mips/clone.S:122: Warning: No .frame pseudo-op used in PIC code libc/sysdeps/linux/mips/clone.S:75: Warning: Pretending global symbol used as branch target is local. libc/sysdeps/linux/mips/crt1.S: Assembler messages: libc/sysdeps/linux/mips/crt1.S:134: Warning: No .cprestore pseudo-op used in PIC code Signed-off-by: Khem Raj <raj.khem@gmail.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>
2009-07-20alpha: 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>
2009-07-20mknod: convert to INLINE_SYSCALL() to sync with glibcMike Frysinger

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>
2009-07-09sh: 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>
2009-07-06sparc: Update syscalls.h to define INTERNAL_SYSCALLAustin Foxley
Signed-off-by: Austin Foxley <austinf@cetoncorp.com>
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>
2009-07-05Provide 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>
2009-07-03i386: 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.

2009-07-03uClibc_arch_features: sync defines between portsMike Frysinger

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>
2009-06-28Add 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>
2009-05-27waitid: 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>

2009-05-05Add position independent code for crt1.S.Carmelo Amoroso
This will generate a Scrt1.o that is linked to executabled when compiled as PIE code (position independent executable) without requiring relocation in .text section (not allowed on uclibc/sh4).
