2009-11-22sh: Add new optimisation to the SH4 memcpyAustin Foxley
This optimization is based on prefetching and 64bit data transfer via FPU (only for the little endianess) 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: Austin Foxley <austinf@cetoncorp.com> Signed-off-by: Giuseppe Cavallaro <peppe.cavallaro@st.com> Signed-off-by: Carmelo Amoroso <carmelo.amoroso@st.com>

2009-11-09disable _POSIX_SPAWN defineMike Frysinger
We don't provide spawn.h let alone any other spawn funcs/types, so don't set up the _POSIX_SPAWN define that some packages (like vlc) check. Signed-off-by: Mike Frysinger <vapier@gentoo.org> Signed-off-by: Austin Foxley <austinf@cetoncorp.com>
2009-11-09regex: call memcpy() ourselvesMike Frysinger
Call the hidden memcpy() ourselves otherwise gcc will emit a call to the public memcpy() which goes through the PLT. Signed-off-by: Mike Frysinger <vapier@gentoo.org> Signed-off-by: Austin Foxley <austinf@cetoncorp.com>
2009-11-09sysctl: 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.

2009-11-09inet_ntop4: avoid inline initializationMike Frysinger
We only need to set the first byte to 0, but gcc likes to zero out the rest of the string with memset() when using this initialization style. Signed-off-by: Mike Frysinger <vapier@gentoo.org> Signed-off-by: Austin Foxley <austinf@cetoncorp.com>

2009-11-09Extend __gen_tempname with mode argumentMikhail Gusarov
sem_open(3) needs to create a temporary file in a way which can't be efficiently implemented in terms of POSIX API. Extend __gen_tempname with mode_t mode argument in order to ease sem_open implementation. Signed-off-by: Mikhail Gusarov <dottedmag@dottedmag.net> Signed-off-by: Austin Foxley <austinf@cetoncorp.com>

2009-10-15malloc: handle size overflows in realloc()Mike Frysinger
The malloc() code checks the incoming size to make sure the header adjustment doesn't cause overflow in the size storage. Add the same check to realloc() to catch stupid stuff like realloc(..., -1).

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>
