2009-07-26enable sbrk() for everyoneMike Frysinger
The sbrk() function can be used to merely query sizes and for that, no-mmu works the same as mmu. It can also sometimes increase data segments on no-mmu systems provided the trailing memory is free. So, there is no real reason to exclude this function for no-mmu ports. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-07-26add missing UTIME_* defines for *at funcsMike Frysinger

2009-07-23Blackfin: fix typo in byteswap.h commitMike Frysinger
The Blackfin port hasn't been compiling cleanly, so this typo was missed in the byteswap unification commit. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-07-23Blackfin: fix incorrect attribute orderMike Frysinger
The order of attributes in a function definition matters and in a few places in the Blackfin code, it was being applied to the return type instead of the function itself. In file included from ldso/ldso/ldso.c:43: ldso/ldso/bfin/elfinterp.c: At top level: ldso/ldso/bfin/elfinterp.c:42: warning: '__visibility__' attribute ignored on non-class types In file included from ldso/ldso/bfin/elfinterp.c:341, from ldso/ldso/ldso.c:43: libc/sysdeps/linux/bfin/crtreloc.c: At top level: libc/sysdeps/linux/bfin/crtreloc.c:91: warning: 'visibility' attribute ignored on non-class types Signed-off-by: Mike Frysinger <vapier@gentoo.org>
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>

2009-07-22add 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>

2009-07-20avr32/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>

2009-07-14Fix 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.

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>

2009-07-03i386: 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.

2009-06-30Fix 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.

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>
