2010-01-14mips/nptl: Pass correct parameters to dl_find_hash when resolving TLS ↵Khem Raj
relocations. Make use of macros from sys/asm.h in crt1.S These two changes are needed for mips nptl to boot once again. Signed-off-by: Khem Raj <raj.khem@gmail.com>

2009-12-19malloc: fix race condition and other bugs in the no-mmu mallocFreeman Wang
Fixes multiple race conditions on mmb list. This was done by making the mmb_heap_lock into a recursive lock and making the regular heap_lock extend to cover the mmb heap handling. Also move the new_mmb allocation up to before the mmb list is iterated through to find the insertion point. When the mmb_heap also runs out and needs to be extended when the regular heap is just extended, the mmb list could be messed up.

2009-12-17check if USE_TLS is defined before useHans-Christian Egtvedt
This patch will convert all the #ifdef USE_TLS and #if USE_TLS to #if defined(USE_TLS) && USE_TLS. By checking if the USE_TLS is defined before checking its value will result in correct behavior for architectures not defining this config symbol.

2009-12-16libc: Add missing header for memsetCarmelo Amoroso
Silence compiler warning by adding the missing string.h header to include memset prototype. Do some code tidy-up removing commented out libc_hidden_proto macros in the meanwhile. Signed-off-by: Carmelo Amoroso <carmelo.amoroso@st.com>
2009-12-16build: Get rids of PIC macro using compiler flag __PIC__ insteadCarmelo Amoroso

2009-12-14sh: fix endianess and optimise the SH4 memcpyGiuseppe Cavallaro
This patch fixes the big-endian code and adds a new optimization only for little endian mode. This optimization is based on prefetching and 64bit data transfer via FPU. Tests shows that ---------------------------------------- Memory bandwidth | Gain | sh4-300 | sh4-200 ---------------------------------------- 512 bytes to 16KiB | ~20% | ~25% from 32KiB to 16MiB | ~190% | ~5% ---------------------------------------- Signed-off-by: Giuseppe Cavallaro <peppe.cavallaro@st.com> Signed-off-by: Carmelo Amoroso <carmelo.amoroso@st.com>

2009-12-13syslog: fix openlog(xx, LOG_KERN) and optimize a bitDenys Vlasenko
The fix: logfac == 0 in openlog(xx, logfac) is allowed now. Corresponding internal openlog() call in vsyslog() uses explicit LOG_USER in order to set it as a default facility. Optimizations: mylock is not recursive now, since a single intenal call of openlog is converted to a call to openlog_internal which assumes that lock is already taken. No recursive locking is possible now. LogFacility is reduced to byte. cache static LogFile in auto variable fd (smaller code). vsyslog with bogus pri parameter wouldn't lock/unlock and mess with signals - it will just return at once. pass NULL as ident string in internal openlog call - same effect as passing LogTag but smaller code. comment out "if (LogTag)" checks - it is never NULL. use the same struct sigaction for setting new sigaction and for saving old one - saves ~32 bytes of stack.

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
Assign each field one by one rather than stack initialization as gcc will call memset() to zero out the rest of the structure -- which we don't care about as the field is unused and not seen outside of the libc. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-10-22inet_ntop4: avoid inline initializationMike Frysinger

2009-10-15malloc: handle size overflows in realloc()Mike Frysinger

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>
