2012-04-07memset: fix define usage for shared libsMike Frysinger2-2/+2
The proper define to check "am I in a shared lib" is "SHARED", not "PIC". The two new memset_chk functions incorrectly depend on "PIC". Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2012-04-05Fix size parameter comparisions.Michael Matz1-6/+6
[BZ #13592] There are several signed compares of the size argument, whereas it really is unsigned. Depending on situations e.g. a "memset(ptr, 0, -1)" segfault (but for the wrong reasons, because jumping into nirvana) or succeeds even. In normal use this is harmless, as a size with signbit set indicates more than half the address space which on x86_64 is impossible to allocate, but as the size is used to index some jump tables this potentially could have other unwanted side effects.

2012-04-03Add __bswap_64 definition for non GCC compilers.Andreas Jaeger3-14/+44
[BZ#13926] Currently __bswap_64 is not defined at all for non-GCC compilers. Define it but guard it with __GLIBC_HAVE_LONG_LONG. endian.h uses __bswap_64, make the functions only available if __GLIBC_HAVE_LONG_LONG is defined.
2012-04-02Call __ctype_init in early glibc startup.Thomas Schwinge4-5/+20
This adds the bits missing from fd5bdc0924e0cfd1688b632068c1b26f3b0c88da.
2012-03-30optimize the following memcpy: sysdeps/i386/i686/multiarch/memcpy-ssse3.SLiubov Dmitrieva1-536/+1449
I've improved the following implementation of memcpy: "sysdeps/i386/i686/multiarch/memcpy-ssse3.S". The patch includes some minor style fixes, but the important part is just using prefetch loops for the case: DATA_CACHE_SIZE_HALF <= len < SHARED_CACHE_SIZE_HALF and src and dst pointers have unequal 16 byte alignments. This gives from 6% - 50% performance boost on the atom machine, about 24,73% in geometric mean.
