Support multiarch for i686. This patch adds multiarch support when configured for i686. I modified some x86-64 functions to support 32bit. I will contribute 32bit SSE string and memory functions later. 2009-07-31 18:53:35 +00:00			`ifeq ($(subdir),csu)`

Add x86 32-bit SSE4.2 string functions. This patch adds 32bit SSE4.2 string functions. It uses -16L instead of 0xfffffffffffffff0L, which works for both 32bit and 64bit long. Tested on 32bit Core i7 and Core 2. 2009-08-04 19:13:43 +00:00
