* config/i386/i386.md (*movtf_internal): Avoid allocating general
registers. Penalize F*r->o alternative to prevent partial memory
stalls. Slightly penalize *roF->*r alternative. Generate SSE
CONST_DOUBLE immediates when optimizing function for size. Do not move
CONST_DOUBLEs directly to memory for !TARGET_MEMORY_MISMATCH_STALL.
(*movxf_internal): Slightly penalize Yx*roF->Yx*r alternative.
(*movdf_internal): Slightly penalize Yd*roF->Yd*r alternative.
(*movdf_internal_rex64): Slightly penalize rm->r, F->m and r->m
alternatives.
(*movsf_internal): Slightly penalize rmF->r and Fr->m alternatives.
(fp_register_operand splitters): Use fp_register_operand
constraint. Do not use FP_REG_P in insn condition.
(any_fp_register_operand splitters): Use any_fp_register_operand
constraint. Do not use ANY_FP_REG_P in insn condition.
* config/i386/i386.md (*pushxf_nointeger): Merge alternatives 1 and 2.
(FP push_operand splitters): Merge {TF,XF,DF}mode splitters.

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*.
