--- Comment #2 from rsandifo at gcc dot gnu.org <rsandifo at gcc dot gnu.org> --- Author: rsandifo Date: Fri Nov 29 13:04:56 2019 New Revision: 278839 URL: https://gcc.gnu.org/viewcvs?rev=278839&root=gcc&view=rev Log: Don't pass booleans as mask types to simd clones (PR 92710) 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.sandif...@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.
