2009-10-15sparc qops: unify & shrinkMike Frysinger
We don't really need to know the exact symbol that caused a failure as long as we know where to start looking. So unify the duplicate code between all funcs and between the sparc variants. This gives us a nice code shrink of ~95%. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-10-15i386: use common INTERNAL_SYSCALL_ERROR_PMike Frysinger

2009-10-14Fix SH bits/kernel_types.h for new kernel headers.Joseph Myers
Recent SH kernel headers merge 32-bit and 64-bit headers, changing the include guards on asm/posix_types.h in the process; update uClibc code depending on those include guards. Signed-off-by: Joseph Myers <joseph@codesourcery.com>

2009-10-08Fix building arm EABIBernhard Reutner-Fischer
The syscall() impl on aeabi comes from syscall-eabi.S thus we do not need the generic syscall() impl. Fixes: AS libc/sysdeps/linux/arm/syscall-eabi.os CC libc/sysdeps/linux/common/syscall.os libc/libc_so.a(syscall.os): In function `syscall': syscall.c:(.text+0x0): multiple definition of `syscall' libc/libc_so.a(syscall-eabi.os):(.text+0x0): first defined here Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>

2009-09-26mips: do not save variables in "hi" or "lo" across system callsDaniel Jacobowitz
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.

2009-09-15sh/user.h: clean up conflicts from kernel user.hAndrew Stubbs
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>

2009-09-06fstatat: fix up behavior on 32/64 bit hostsMike Frysinger
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.

2009-09-06xstatconv: drop useless hidden codeMike Frysinger
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>

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>

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>

2009-07-26enable nanosecond stat support for everyoneMike Frysinger
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>
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>

2009-07-23Blackfin: 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.

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>
