early-remat.c:process_block wasn't handling insns that set multiple candidate registers, which led to an assertion failure at the end of the main loop. Instructions that set two pseudos aren't rematerialisation candidates in themselves, but we still need to track them if another instruction that sets the same register is a rematerialisation candidate. 2020-04-16 Richard Sandiford <richard.sandiford@arm.com> gcc/ PR rtl-optimization/94605 * early-remat.c (early_remat::process_block): Handle insns that set multiple candidate registers. gcc/testsuite/ PR rtl-optimization/94605 * gcc.target/aarch64/sve/pr94605.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.
