The target hook aarch64_class_max_nregs returns the incorrect result for 64-bit structure modes like V31DImode or V41DFmode etc. The calculation of the nregs is based on the size of AdvSIMD vector register for 64-bit modes which ought to be UNITS_PER_VREG / 2. This patch fixes the register size. gcc/ChangeLog: PR target/112577 * config/aarch64/aarch64.cc (aarch64_class_max_nregs): Handle 64-bit vector structure modes correctly.
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.
