Log message:
PR target/18668
* config/i386/i386.h (x86_fisttp): New.
(TARGET_FISTTP): New macro.
* config/i386/i386.c (x86_fisttp): Set for NOCONA.
(output_fix_trunc): Add fisttp parameter. Generate fisttp x87
instruction when fisttp flag is set.
* config/i386/i386-protos.h (output_fix_trunc): Change declaration.
* config/i386/i386.md (type attribute): Add fisttp.
(unit attribute): Set to i387 for fisttp type.
(X87MODEF, X87MODEI, SSEMODEF, SSEMODEI24): New mode macros.
(fix_truncxfdi2, fix_truncxfsi2): Generate fisttp patterns for
TARGET_FISTTP.
(fix_truncdfdi2, fix_truncsfdi2, fix_truncdfsi2, fix_truncsfsi2):
Generate fisttp patterns for TARGET_FISTTP. Implement using mode
macros.
(fix_truncxfhi2, fix_truncdfhi2, fix_truncsfhi2): Generate fisttp
patterns for TARGET_FISTTP. Enable patterns for
(TARGET_FISTTP && !TARGET_SSE_MATH). Implement using mode macros.
(fix_trunc<mode>_i387_fisttp_1, fix_trunc<mode>_i387_fisttp,
fix_trunc<mode>_i387_fisttp_with_temp): New instruction patterns to
implement fisttp x87 insn.
(fix_trunc*_i387_fisttp splitters): New patterns.
(*fix_truncdi_i387, *fix_truncsi_i387, *fix_trunchi_i387):
Rename to *fix_trunc<mode>_i387_1. Implement using mode macros.
Disable patterns for TARGET_FISTTP. Add comment about FLAGS_REG
clobber.
(fix_truncdi_memory, fix_truncdi_nomemory, fix_trunchi_nomemory):
Rename to fix_trunc<mode>_i387 and fix_trunc<mode>_i387_with_temp.
Implement using mode macros. Disable patterns for TARGET_FISTTP.
(fix_truncsi_memory, fix_truncsi_nomemory, fix_trunchi_memory,
fix_trunchi_nomemory): Rename to fix_trunc<mode>_i387 and
fix_trunc<mode>_i387_with_temp. Implement using mode macros.
Disable patterns for TARGET_FISTTP.
(fix_trunc*_i387 splitters): Implement usign mode macros.
(fix_truncdfdi_sse, fix_truncsfdi_sse, fix_truncdfsi_sse,
fix_truncsfsi_sse): Disable for (TARGET_FISTTP && !TARGET_SSE_MATH).
(fix_trunx*_sse peephole2s): Implement using mode macros.
