[PATCH v2] gcc: xtensa: fix NAND code in xtensa_expand_atomic

2018-09-04 Thread Max Filippov
NAND is ~(a1 & a2), but xtensa_expand_atomic does ~a1 & a2. That fixes libatomic tests atomic-op-{1,2}. gcc/ 2018-09-04 Max Filippov * config/xtensa/xtensa.c (xtensa_expand_atomic): Reorder AND and XOR operations in NAND case. --- Changes v1->v2: - put final inversion result in
