i386.c (initial_ix86_tune_features): Add X86_TUNE_USE_VECTOR_FP_CONVERTS.
2008-10-08 H.J. Lu <hongjiu.lu@intel.com>
* config/i386/i386.c (initial_ix86_tune_features): Add
X86_TUNE_USE_VECTOR_FP_CONVERTS.
* config/i386/i386.h (ix86_tune_indices): Likewise.
(TARGET_USE_VECTOR_FP_CONVERTS): New.
* config/i386/i386.md: Check TARGET_USE_VECTOR_FP_CONVERTS
instead of (TARGET_USE_VECTOR_CONVERTS || TARGET_GENERIC)
for FP to FP splitters.
