The patch below detects when we're doing a little-endian memory access and stores to the correct memory locations. 2020-07-22 Peter Bergner <berg...@linux.ibm.com> gcc/ PR target/96236 * config/rs6000/rs6000-call.c (rs6000_gimple_fold_mma_builtin): Handle little-endian memory ordering. gcc/testsuite/ PR target/96236 * gcc.target/powerpc/mma-double-test.c: Update storing results for correct little-endian ordering. * gcc.target/powerpc/mma-single-test.c: Likewise.
