This patch generalises the SVE BIC pattern so that it doesn't rely on REG_EQUAL notes. The danger with relying on the notes is that an optimisation could for example replace the original (not ...) note with an (unspec ... UNSPEC_MERGE_PTRUE) in which the predicate is a constant. That's a legitimate change and could even be useful in some situations. The patch also makes the operand order match the SVE operand order in both the vector and predicate BIC patterns, which makes things easier for the ACLE. 2019-08-14 Richard Sandiford <richard.sandiford@arm.com> Kugan Vivekanandarajah <kugan.vivekanandarajah@linaro.org> gcc/ * config/aarch64/aarch64-sve.md (bic<mode>3): Rename to... (*bic<SVE_I:mode>3): ...this. Match the form that an SVE inverse actually has, rather than relying on REG_EQUAL notes. Make the insn operand order match the SVE operand order. (*<nlogical><PRED_ALL:mode>3): Make the insn operand order match the SVE operand order. Co-Authored-By: Kugan Vivekanandarajah <kuganv@linaro.org> From-SVN: r274416 |

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.
