d0adc92230 i386/x86_64: Optimize feholdexcept. 2012-03-19 06:51:06 -07:00
Richard Henderson
0fe0f1f86f Create and use libc_feupdateenv_test. 
We can reduce the number of STMXCSR, and often we can avoid the
call to __feraiseexcept.

Richard Henderson
4851a949b4 Make inline __isnan, __isinf_ns, __finite generic. 
For code generation to stay identical on x86_64, this requires that
we define the fp word manipulation macros before including the
generic header.

08cf777f9e Really fix AVX tests 
There is no problem with strcmp, it doesn't use the YMM registers.
The math routines might since gcc perhaps generates such code.
Introduce bit_YMM_USBALE and use it in the math routines.

7e4ba49cd3 Enable SSE2 memset for AMD'supcoming Orochi processor. 
This patch enables SSE2 memset for AMD's upcoming Orochi processor.
This patch also fixes the following bug:
For misaligned blocks larger than > 144 Bytes, memset branches into
the integer code path depending on the value of misalignment even if
the startup code chooses the SSE2 code path upfront, when multiarch
is enabled.

c0dde15b5d 32bit memset-sse2.S fails with uneven cache size 
32bit memset-sse2.S assumes cache size is multiple of 128 bytes.  If
it isn't true, memset-sse2.S will fail.  For example, a processor can
have 24576 KB L3 cache and 20 cores. That is 2516582 byte per core. Half
of it is 1258291, which isn't helpful for vector instructions.  This
patch rounds cache sizes to multiple of 256 bytes and adds "raw" cache
sizes.
