Subject: c-family: Use -Wdiscarded-qualifiers for ignored qualifiers in __atomic_*
X-Git-Tag: basepoints/gcc-15~3388
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=a48dd581bf917fcd52fb9eab60943825ed96b6d4;p=thirdparty%2Fgcc.git

c-family: Use -Wdiscarded-qualifiers for ignored qualifiers in __atomic_*

This matches other compiler diagnostics.  No test updates are needed
because c-c++-common/pr95378.c does not match a specific -W option.

Fixes commit d2384b7b24f8557b66f6958a05ea99ff4307e75c ("c-family:
check qualifiers of arguments to __atomic built-ins (PR 95378)").

gcc/c-family/

	PR c/113050
	* c-common.cc (get_atomic_generic_size): Use
	OPT_Wdiscarded_qualifiers instead of
	OPT_Wincompatible_pointer_types.
