This is what I committed.
The patch introduced bootstrap failure on alpha-linux-gnu.
Non-bootstrapped build regresses:
FAIL: gcc.dg/torture/pr69542.c -O2 (test for excess errors)
FAIL: gcc.dg/torture/pr69542.c -O2 -flto -fno-use-linker-plugin
-flto-partition=none (test for excess errors)
FAIL: gcc.dg/torture/pr69542.c -Os (test for excess errors)
where all failures are -fcompare-debug failures.
Is the bootstrap failure also of this nature, or do you suspect
something else?
