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.

2009-12-09test_dlopen: Remove extra -lpthread from LD_FLAGS for dltest{2}Filippo Arcidiacono
dltest and dltest2 do not refer any symbols implemented in pthread library, so do not explicitly link them with pthread. It is required only for the shared objects that are loaded via dlopen by those tests.

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>
