Bootstrapped and regtested on loongarch64-linux-gnu. Ok for trunk?
LGTM!
Thanks!
Changes from v2 to v3:
- Reorder the ICE fix before the semantic fix
- Fix incorrect RTL for the fcc output
Changes from v1 to v2:
- Use { xfail } in { dg-final } instead of { dg-xfail-if }, because it's
the thread simulation test that we know to fail with current GDB, not
the compile test.
