* Improve 64bit memcpy/memmove for Atom, Core 2 and Core i7H.J. Lu2010-06-301-1/+4
| | | | | | | This patch includes optimized 64bit memcpy/memmove for Atom, Core 2 and Core i7. It improves memcpy by up to 3X on Atom, up to 4X on Core 2 and up to 1X on Core i7. It also improves memmove by up to 3X on Atom, up to 4X on Core 2 and up to 2X on Core i7.
* Fix bugs in x86-32 strcmp-sse4.S and strcmp-ssse3.SH.J. Lu2010-04-151-4/+35

* Cleanup strings.h.Ulrich Drepper2010-01-101-14/+19
| | | | Cleanup the strings.h header for XPG7 and update the tests.
* Add support for XPG7 testing.Ulrich Drepper2010-01-093-8/+9
| | | | | The header conformance testing code needed extending for XPG7. This exposed a few bugs in the headers. There are more changes to come.

* SSE4.2 strstr/strcasestr for x86-64.H.J. Lu2009-07-202-4/+15
| | | | | This patch implements SSE4.2 strstr/strcasestr, using Knuth-Morris-Pratt string searching algorithm.
* SSSE3 strcpy/stpcpy for x86-64H.J. Lu2009-07-022-11/+13
| | | | | | This patch adds SSSE3 strcpy/stpcpy. I got up to 4X speed up on Core 2 and Core i7. I disabled it on Atom since SSSE3 version is slower for shorter (<64byte) data.
