The solution is to use create_tmp_reg_or_ssa_name(), which knows when to create either an SSA or register temporary. 2021-06-14 Peter Bergner <berg...@linux.ibm.com> gcc/ PR target/100777 * config/rs6000/rs6000-call.c (rs6000_gimple_fold_mma_builtin): Use create_tmp_reg_or_ssa_name(). gcc/testsuite/ PR target/100777 * gcc.target/powerpc/pr100777.c: New test.
