2013-12-18Remove use of SSE4.2 functions for strstr on i686Andreas Schwab6-49/+2
The SSE4.2 have been removed from x86_64 by commit 584b18eb. This patch fixes the build on i686, which attempts to use the removed files.

2012-04-07memset: fix define usage for shared libsMike Frysinger1-1/+1
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>
2012-03-30optimize 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.

2011-12-23Fix wrong copying processing for last bytes in x86-32 wcscpyLiubov Dmitrieva1-41/+21
Wrong copy algorithm for last bytes, not thread safety. In some particular cases it uses the destination memory beyond the string end for 16-byte load, puts changes into that part that is relevant to destination string and writes whole 16-byte chunk into memory. I have a test case where the memory beyond the string end contains malloc/free data, that appear corrupted in case free() updates it in between the 16-byte read and 16-byte write.
