This patch adds support for unpacked SVE SABD and UABD. It also rewrites the patterns so that they match as combine patterns without the need for REG_EQUAL notes. Finally, there was no pattern for merging with the second input, which can be handled by reversing the operands. The type suffix needs to be taken from the element size rather than the container size. gcc/ * config/aarch64/aarch64-sve.md (<su>abd<mode>_3): Extend from SVE_FULL_I to SVE_I. (*aarch64_cond_<su>abd<mode>_2): Likewise. (*aarch64_cond_<su>abd<mode>_any): Likewise. (@aarch64_pred_<su>abd<mode>): Likewise. Use UNSPEC_PRED_X for the max and min but not for the minus. (*aarch64_cond_<su>abd<mode>_3): New pattern. gcc/testsuite/ * g++.target/aarch64/sve/abd_1.C: New test. * g++.target/aarch64/sve/cond_abd_1.C: Likewise. * g++.target/aarch64/sve/cond_abd_2.C: Likewise. * g++.target/aarch64/sve/cond_abd_3.C: Likewise. * g++.target/aarch64/sve/cond_abd_4.C: Likewise.
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.
