2009-11-26sync confname, environments with glibcBernhard Reutner-Fischer
Plus related synch. Add a testcase for the sysconf variables based on the one from glibc Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>
2009-11-25in6_{pktinfo,mtuinfo}: provide type if IPV6 is onBernhard Reutner-Fischer
Disable some IPv6 header defines if IPv6 is off. Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.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>
2009-11-23futimens: Ducument why we need manual hidden_protoBernhard Reutner-Fischer
Also, remove unneeded __need_timespec (It cuts off a tiny bit of work for CPP but is of course not strictly needed). Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>
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>

sem_open(3) needs to create a temporary file in a way which can't be efficiently implemented in terms of POSIX API.

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).
