--- Comment #5 from Patrick O'Neill <patrick at rivosinc dot com> --- I don't have a big-endian environment set up to validate the issue/test a fix and I likely won't be able to get to this for a while. The relevant code is here (untouched by the recent patches): Trunk https://gcc.gnu.org/git/?p=gcc.git;a=blob;f=gcc/config/riscv/sync.md;h=9fc626267de3840ce15d196bff72440a980fd234;hb=HEAD#l535 GCC 12 https://gcc.gnu.org/git/?p=gcc.git;a=blob;f=gcc/config/riscv/sync.md;h=86b41e6b00a9331ed4b46e73cc66c102c6d2d981;hb=2ee5e4300186a92ad73f1a1a64cb918dc76c8d67#l155 The main difference from 12->trunk in this testcase is that AMOOR now uses .aqrl instead of a fence. That does not affect this testcase, so a fix on trunk should be applicable to the 12 branch (and vice-versa). Thanks for the bug report!
