noticed the new added "Wno-frame-address.c" fail on arm-none-linux-gnueabihf
native test.
from the comments in the testcase:
+/* Verify that -Wframe-address is not enabled by default by enabling
+ -Werror and verifying the test still compiles. */
seems you want to make sure -Wframe-address work correctly with -Werror, while
for arm,
return_address hook is defined to only support level 0, NULL_RTX returned for
all other levels,
so this caused Wno-frame-address.c failed in those tem != NULL check for
builtin_return_address.
