From 2a17b2397059117b7334e2e569971a3bc5731abb Mon Sep 17 00:00:00 2001 From: Max Filippov Date: Tue, 4 Sep 2018 17:43:20 +0000 Subject: [PATCH] gcc: xtensa: fix NAND code in xtensa_expand_atomic 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.
