For memory loads/stores (that contain a MEM rtx) sh_rtx_costs would wrongly report a cost lower than 1 insn which is not accurate as it makes loads/stores appear cheaper than simple arithmetic insns. The cost of a load/store insn is at least 1 insn plus the cost of the address expression (some addressing modes can be considered more expensive than others due to additional constraints). gcc/ChangeLog: PR target/113533 * config/sh/sh.cc (sh_rtx_costs): Adjust cost estimation of MEM rtx to be always at least COST_N_INSNS (1). Forward speed argument to sh_address_cost. Co-authored-by: Roger Sayle <roger@nextmovesoftware.com> |

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.
