In this PR we assigned a vector mask type to the result of a comparison and then tried to pass that mask type to a simd clone, which expected a normal (non-mask) type instead. This patch simply punts on call arguments that have a mask type. A better fix would be to pattern-match the comparison to a COND_EXPR, like we would if the comparison was stored to memory, but doing that isn't gcc 9 or 10 material. Note that this doesn't affect x86_64-linux-gnu because the ABI promotes bool arguments to ints. 2019-11-29 Richard Sandiford <richard.sandiford@arm.com> gcc/ PR tree-optimization/92710 * tree-vect-stmts.c (vectorizable_simd_clone_call): Reject vector mask arguments. gcc/testsuite/ PR tree-optimization/92710 * gcc.dg/vect/pr92710.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.
