X-Git-Tag: basepoints/gcc-13~2036
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=1935db296892bbd9fc597889237528bd7e080ab1;p=thirdparty%2Fgcc.git

Avoid more -Wformat-diag warnings [PR103758]

Let's use "%<x>, %<y>, or %<z>" rather than "[x|y|z]" as in the rest of
our codebase.

	PR c++/103758

gcc/c-family/ChangeLog:

	* c-pragma.c (handle_pragma_scalar_storage_order): Use %< %> in
	diagnostic messages.
	(handle_pragma_diagnostic): Likewise.

gcc/testsuite/ChangeLog:

	* gcc.dg/sso-6.c: Update dg-warning.
