2012-04-10Use __builtin_bswap32/64 in x86_64 <bits/byteswap.h>H.J. Lu
2012-04-11New ld.so argument --inhibit-ldcache to disable ld.so.cache lookupSiddhesh Poyarekar
It may sometimes be desirable to make the dynamic linker only pick up libraries from the library path and rpath and not look at the ld.so.cache that ldconfig generates. An example of such a use case is the glibc testsuite where the dynamic linker must not be influenced by any external paths or caches. This change adds a new option --inhibit-ldcache that when used, tells the dynamic linker to not use ld.so.cache even if it is available.

2012-04-07memset: fix define usage for shared libsMike Frysinger
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 Matz
[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 Jaeger
[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.

2012-03-30optimize the following memcpy: sysdeps/i386/i686/multiarch/memcpy-ssse3.SLiubov Dmitrieva
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.
