processor_costs has costs of RTL expressions with pseudo registers and and costs of hard register moves: 1. Costs of RTL expressions are used to generate the most efficient RTL operations with pseudo registers. 2. Costs of hard register moves are used by register allocator to decide how to allocate and move hard registers. Since relative costs of pseudo register load and store versus pseudo register moves in RTL expressions can be different from relative costs of hard registers, we should separate costs of RTL expressions with pseudo registers from costs of hard registers so that register allocator and RTL expressions can be improved independently. This patch moves costs of hard register moves to the new hard_register field and duplicates costs of moves which are also used for costs of RTL expressions. PR target/90878 * config/i386/i386.c (inline_memory_move_cost): Use hard_register for costs of hard register moves. (ix86_register_move_cost): Likewise. * config/i386/i386.h (processor_costs): Move costs of hard register moves to hard_register. Add int_load, int_store, xmm_move, ymm_move, zmm_move, sse_to_integer, integer_to_sse, sse_load, sse_store, sse_unaligned_load and sse_unaligned_store for costs of RTL expressions. * config/i386/x86-tune-costs.h: Move costs of hard register moves to hard_register. Duplicate int_load, int_store, xmm_move, ymm_move, zmm_move, sse_to_integer, integer_to_sse, sse_load, sse_store for costs of RTL expressions. From-SVN: r274543 |

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.
