Summary: _MM_HINT_T0,1,2 defined incorrectly (xmmintrin.h)
Product: clang
Version: 2.7
Platform: PC
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P
Component: Headers
AssignedTo: [email protected]

_mm_prefetch(0,_MM_HINT_T0) compiles to prefetcht2. Since _mm_prefetch() is
implemented in terms of __builtin_prefetch, the hints should be defined the
same way as GCC:
_MM_HINT_T0 3
_MM_HINT_T1 2
_MM_HINT_T2 1
_MM_HINT_NTA 0
This is a 2-line fix in the xmmintrin.h header.
