2010-02-10libc_sh: Add a sysdep header for shCarmelo Amoroso
A new sysdep header for sh (ported from NPTL branch) to provide some useful macros in asm code: ENTRY: an entry point visible from C PSEUDO: a wrapper for syscall with proper errno checking SYSCALL_ERROR_HANDLER: errno check (suitable for TLS) This will help in NPTL integration. Signed-off-by: Carmelo Amoroso <carmelo.amoroso@st.com>
2010-02-10libc: Add a common sysdep headerCarmelo Amoroso
Add a common header file to provide macros useful in asm code: C_LABEL to construct the asm name for a C symbol cfi_xxx to generate eh_frame unwind information. Ported from NPTL branch. Signed-off-by: Carmelo Amoroso <carmelo.amoroso@st.com>

Thanks, indeed. If we came into "#elif WORDSIZE == 32" block, above condition never be true. So we can just move this statement out of "#if...#elif...#elif...#endif" block. Here is a revised patch. ------------------------------------------------------ From: Atsushi Nemoto <anemo@mba.ocn.ne.jp> Subject: [PATCH] getdents: Fix mips64 build Some archs (such as mips64) do not have getdents64 syscall but have getdents syscall. Define alias for it. This fixes regression from 0.9.30.1. Backgrounds: This is once done by commit e8b1c674. But after the commit 33bcf733 ("Use getdents syscall if kernel provide supports for this instead of relying upon getdents64."), if __ASSUME_GETDENTS32_D_TYPE was defined the alias for getdents64 is not defined. The macro __ASSUME_GETDENTS32_D_TYPE had been effectively ignored until 0.9.30.1 but the commit 0f0f20ab ("Move kernel-features.h header from the linuxthread directory to a common one...") really enables it.

2010-01-21avr32: add varargs handling of prctl syscallHans-Christian Egtvedt
prctl is defined to use varargs in the header file, hence it needs varargs specific handling in the source. This patch properly handles the variodic argument before the syscall is passed to the kernel for the AVR32 architecture. Signed-off-by: Hans-Christian Egtvedt <hans-christian.egtvedt@atmel.com>

2009-12-03sh: Add a prototype for the gcc __set_fpscr internal functionCarmelo Amoroso
The sh port uses the gcc __set_fpscr internal function, but neither gcc nor glibc creates a prototype for it. This leads to a bunch of random warnings about implicit decls during the build. Signed-off-by: Mike Frysinger <vapier@gentoo.org> Signed-off-by: Carmelo Amoroso <carmelo.amoroso@st.com>

2009-11-23nommu: use MAP_UNINITIALIZE for mallocsMike Frysinger
Now that the kernel supports MAP_UNINITIALIZE, have the malloc places use it to get real uninitialized memory on no-mmu systems. This avoids a lot of normally useless overhead involved in zeroing out all of the memory (sometimes multiple times). Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-11-23bits/mmap.h: unify ala linux asm-generic effortsMike Frysinger
Most ports have the same exact mman bit defines, so let's unify things like the linux kernel has with the asm-generic efforts. A few ports are left behind as they are non-trivial to merge -- the arch maintainers can tackle it if they care. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2009-10-22sysctl: avoid inline initializationMike Frysinger
