This patch adds extended costing to cost the creation of constants and the manipulation of constants. The default values provided are based on architectural expectations and each cost models can be individually tweaked as needed. The changes in this patch covers: * Construction of PARALLEL or CONST_VECTOR: Adds better costing for vector of constants which is based on the constant being created and the instruction that can be used to create it. i.e. a movi is cheaper than a literal load etc. * Construction of a vector through a vec_dup. gcc/ChangeLog: * config/arm/aarch-common-protos.h (struct vector_cost_table): Add movi, dup and extract costing fields. * config/aarch64/aarch64-cost-tables.h (qdf24xx_extra_costs, thunderx_extra_costs, thunderx2t99_extra_costs, thunderx3t110_extra_costs, tsv110_extra_costs, a64fx_extra_costs): Use them. * config/arm/aarch-cost-tables.h (generic_extra_costs, cortexa53_extra_costs, cortexa57_extra_costs, cortexa76_extra_costs, exynosm1_extra_costs, xgene1_extra_costs): Likewise * config/aarch64/aarch64-simd.md (aarch64_simd_dup<mode>): Add r->w dup. * config/aarch64/aarch64.c (aarch64_rtx_costs): Add extra costs. gcc/testsuite/ChangeLog: * gcc.target/aarch64/vect-cse-codegen.c: New test. |

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.
