--- Comment #7 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-11 branch has been updated by Peter Bergner <berg...@gcc.gnu.org>: https://gcc.gnu.org/g:585667735e9fb7a38357a84d4d25206a8ccec576 commit r11-8951-g585667735e9fb7a38357a84d4d25206a8ccec576 Author: Peter Bergner <berg...@linux.ibm.com> Date: Thu Aug 19 17:33:29 2021 -0500 rs6000: Fix ICE expanding lxvp and stxvp gimple built-ins [PR101849] PR101849 shows we ICE on a test case when we pass a non __vector_pair * pointer to the __builtin_vsx_lxvp and __builtin_vsx_stxvp built-ins that is cast to __vector_pair *. The problem is that when we expand the built-in, the cast has already been removed from gimple and we are only given the base pointer. The solution used here (which fixes the ICE) is to catch this case and convert the pointer to a __vector_pair * pointer when expanding the built-in. 2021-08-19 Peter Bergner <berg...@linux.ibm.com> gcc/ PR target/101849 * config/rs6000/rs6000-call.c (rs6000_gimple_fold_mma_builtin): Cast pointer to __vector_pair *. gcc/testsuite/ PR target/101849 * gcc.target/powerpc/pr101849.c: New test.
