* mips: do not save variables in "hi" or "lo" across system callsDaniel Jacobowitz2009-09-261-2/+2
| | | | | | | | | The kernel does not save these registers across system calls. GCC 4.4 has gotten more aggressive about using them for temporary variables, so this shows up as intermittent crashes if you use a recent compiler.

* sh/user.h: clean up conflicts from kernel user.hAndrew Stubbs2009-09-151-0/+11
| | | | | | | | | | | | This patch makes sufficient modifications to the SH sys/user.h to be able to build and run gdbserver with Linux kernel 2.6.30. The problem is that both the kernel and library headers define the same symbols, thus making it impossible in include both headers. The patch undefines the kernel symbols in favour of the library symbols. Signed-off-by: Andrew Stubbs <ams@codesourcery.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>

* fstatat: fix up behavior on 32/64 bit hostsMike Frysinger2009-09-064-2/+32
| | | | | | | | | | | | The fstatat() syscall is a little funky in that it sometimes changes name between 32 and 64 bit hosts, but it should always operate on a 64bit stat structure. So for the fstatat() function, make sure we convert it from a 64bit kstat to a 32bit stat. Along these lines, we need to restore the __xstat32_conv() function.

* xstatconv: drop useless hidden codeMike Frysinger2009-09-061-4/+2
| | | | | | | The xstatconv.h header already sets up hidden prototypes for us, so no need to duplicate the code. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Revert "syscall.c: Use common syscall.c for ARM"Khem Raj2009-09-063-0/+129
| | | | | | | | This reverts commit b1913a876059949e6c309bafade55e9425ef33fb. OABI is still a requirement. So we override the common syscall implementation specifically for arm port. Signed-off-by: Khem Raj <raj.khem@gmail.com>
* drop last _syscall6 checksMike Frysinger2009-08-312-2/+2

* honour NO_LONG_DOUBLE_MATHBernhard Reutner-Fischer2009-08-3018-19/+81

* Build posix_fadvice{64} only when UCLIBC_HAS_ADVANCED_REALTIME is set.Khem Raj2009-08-305-9/+22
| | | | | | | | | Right now for ARM, MIPS, Xtensa and powerpc posix_fadvise routines are included conditionally. They should only be enabled when UCLIBC_HAS_ADVANCED_REALTIME is set. Also fix code style in powerpc/posix_fadvise64.c Signed-off-by: Khem Raj <raj.khem@gmail.com>

* Add posix_fadvise and posix_fadvise64 for powerpcKhem Raj2009-08-302-0/+106
| | | | | | | | | The syscall is having different number of params and in one case the parameters are passed in differently. This patch add powerpc specific versions of these functions. Signed-off-by: Khem Raj <raj.khem@gmail.com>

* force arches to provide sys/user.hMike Frysinger2009-07-261-1/+1
| | | | | | | Now that Linux is no longer installing linux/user.h, arches will have to provide their own. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* add missing UTIME_* defines for *at funcsMike Frysinger2009-07-2611-10/+64

* enable nanosecond stat support for everyoneMike Frysinger2009-07-2635-409/+292
| | | | | | | | | | | | | Fill out the stat structure so that the nanosecond resolution support is always available. There is a small code size increase for a few ports (three additional assignments in xstatconv), but otherwise everything should remain the same. While we're here, punt __old_kernel_stat from the few headers that still define it as it is unused in uClibc and causes compile errors after these nanosecond changes. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* enable sbrk() for everyoneMike Frysinger2009-07-261-4/+0
| | | | | | | | | 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.

* Blackfin: fix typo in byteswap.h commitMike Frysinger2009-07-231-1/+1

* Blackfin: fix incorrect attribute orderMike Frysinger2009-07-231-1/+1
| | | | | | | | | | | | | | | | | 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.

* create real common vfork() functionMike Frysinger2009-07-233-28/+14
| | | | | | | | | 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>

* byteswap: unify common definitionsMike Frysinger2009-07-2110-632/+242
| | | | | | | | | 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>
* s/UCLIBC_INTERNAL/_LIBC/gDenys Vlasenko2009-07-212-3/+3
| | | | | | | | | | 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>

* avr32/microblaze/vax: punt local byteswap.hMike Frysinger2009-07-203-175/+0
| | | | | | | 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>

* INLINE_SYSCALL_NCS: scope out local vars to avoid conflictsMike Frysinger2009-07-201-6/+6
| | | | | | | | | | | 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>
