2014-09-19 Michael Meissner <meissner@linux.vnet.ibm.com> * config/rs6000/predicates.md (fusion_gpr_mem_load): Move testing for base_reg_operand to be common between LO_SUM and PLUS. (fusion_gpr_mem_combo): New predicate to match a fused address that combines the addis and memory offset address. * config/rs6000/rs6000-protos.h (fusion_gpr_load_p): Change calling signature. (emit_fusion_gpr_load): Likewise. * config/rs6000/rs6000.c (fusion_gpr_load_p): Change calling signature to pass each argument separately, rather than using an operands array. Rewrite the insns found by peephole2 to be a single insn, rather than hoping the insns will still be together when the peephole pass is done. Drop being called via a normal peephole. (emit_fusion_gpr_load): Change calling signature to be called from the fusion_gpr_load_<mode> insns with a combined memory address instead of the peephole pass passing the addis and offset separately. * config/rs6000/rs6000.md (UNSPEC_FUSION_GPR): New unspec for GPR fusion. (power8 fusion peephole): Drop support for doing power8 via a normal peephole that was created by the peephole2 pass. (power8 fusion peephole2): Create a new insn with the fused address, so that the fused operation is kept together after register allocation is done. (fusion_gpr_load_<mode>): Likewise.

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*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
