* sh/user.h: clean up conflicts from kernel user.hAndrew Stubbs2009-09-181-0/+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.

* fstatat: fix up behavior on 32/64 bit hostsMike Frysinger2009-09-184-2/+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 Frysinger2009-09-181-4/+2

| | | | | | | | | 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> Signed-off-by: Austin Foxley <austinf@cetoncorp.com>

* enable nanosecond stat support for everyoneMike Frysinger2009-08-1935-409/+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.

* enable sbrk() for everyoneMike Frysinger2009-08-191-4/+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 incorrect attribute orderMike Frysinger2009-08-191-1/+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.

* byteswap: unify common definitionsMike Frysinger2009-08-1910-632/+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.

| | | | | | | | | | | Undo my old mistake. I added UCLIBC_INTERNAL define, but later I realized _LIBC is doing exactly the same thing.

* INLINE_SYSCALL_NCS: scope out local vars to avoid conflictsMike Frysinger2009-08-191-6/+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> Signed-off-by: Austin Foxley <austinf@cetoncorp.com>

* Fix ARM syscall argument loading.Joseph Myers2009-08-191-14/+21
| | | | | | | | | | | | 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.
