--- Comment #8 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Peter Bergner <berg...@gcc.gnu.org>: https://gcc.gnu.org/g:2432c47970024db6410708b582a901259dabaae1 commit r11-7196-g2432c47970024db6410708b582a901259dabaae1 Author: Peter Bergner <berg...@linux.ibm.com> Date: Thu Feb 11 14:15:26 2021 -0600 rs6000: Fix invalid address used in MMA built-in function The mma_assemble_input_operand predicate is too lenient on the memory operands it will accept, leading to an ICE when illegitimate addresses are passed in. The solution is to only accept memory operands with addresses that are valid for quad word memory accesses. The test case is a minimized test case from the Eigen library. The creduced test case is very noisy with respect to warnings, so the test case has added -w to silence them. 2021-02-11 Peter Bergner <berg...@linux.ibm.com> gcc/ PR target/99041 * config/rs6000/predicates.md (mma_assemble_input_operand): Restrict memory addresses that are legal for quad word accesses. gcc/testsuite/ PR target/99041 * g++.target/powerpc/pr99041.C: New test.
