[PATCH] Make SSE Run Time option.
...g the non-FP version, however the run time flags
need to be settable with a non FP SSE mode so that exceptions are avoided.
I thus propose a set of defines like this instead of the ones in our
initial patch:
#define CPU_MODE_NONE 0
#define CPU_MODE_MMX 1 // Base Intel MMX x86
#define CPU_MODE_3DNOW 2 // Base AMD 3Dnow extensions
#define CPU_MODE_SSE 4 // Intel Integer SSE instructions
#define CPU_MODE_3DNOWEXT 8 // AMD 3Dnow extended instructions
#define CPU_MODE_SSEFP 16 // SSE FP modes, mainly support for xmm registers
#define CPU_MODE_SSE2 32 // Intel SSE2 instructions
#define...

[PATCH] Make SSE Run Time option. Add Win32 SSE code

In the Atholon XP 2400+ that we have in our QA lab (Win2000 ) if you run
that code it generates an Illegal Instruction Error. In addition,
