Subject: The constant folder's diagnosic mechanism is irrelevant for C; don't bother
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=485ea8e8ea6fd0ab406f10795e35087ee9a07689;p=clang

The constant folder's diagnosic mechanism is irrelevant for C; don't bother
producing a C-only diagnostic.
