x86: Add TARGET_SSE_PARTIAL_REG_[FP_]CONVERTS_DEPENDENCY
1. Replace TARGET_SSE_PARTIAL_REG_DEPENDENCY with
TARGET_SSE_PARTIAL_REG_FP_CONVERTS_DEPENDENCY in SSE FP to FP splitters.
2. Replace TARGET_SSE_PARTIAL_REG_DEPENDENCY with
TARGET_SSE_PARTIAL_REG_CONVERTS_DEPENDENCY in SSE INT to FP splitters.
3. Also check TARGET_SSE_PARTIAL_REG_FP_CONVERTS_DEPENDENCY and
TARGET_SSE_PARTIAL_REG_DEPENDENCY when handling avx_partial_xmm_update
attribute. Don't convert AVX partial XMM register update if there is no
partial SSE register dependency for SSE conversion.
gcc/
* config/i386/i386-features.c (remove_partial_avx_dependency):
Also check TARGET_SSE_PARTIAL_REG_FP_CONVERTS_DEPENDENCY and
and TARGET_SSE_PARTIAL_REG_CONVERTS_DEPENDENCY before generating
vxorps.
* config/i386/i386.h (TARGET_SSE_PARTIAL_REG_FP_CONVERTS_DEPENDENCY):
New.
(TARGET_SSE_PARTIAL_REG_CONVERTS_DEPENDENCY): Likewise.
* config/i386/i386.md (SSE FP to FP splitters): Replace
TARGET_SSE_PARTIAL_REG_DEPENDENCY with
TARGET_SSE_PARTIAL_REG_FP_CONVERTS_DEPENDENCY.
(SSE INT to FP splitter): Replace TARGET_SSE_PARTIAL_REG_DEPENDENCY
with TARGET_SSE_PARTIAL_REG_CONVERTS_DEPENDENCY.
* config/i386/x86-tune.def
(X86_TUNE_SSE_PARTIAL_REG_FP_CONVERTS_DEPENDENCY): New.
(X86_TUNE_SSE_PARTIAL_REG_CONVERTS_DEPENDENCY): Likewise.
