Subject: c-typeck.c (composite_type, [...]): Abort if we have type qualifiers at all.
X-Git-Tag: releases/gcc-4.0.0~7421
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=de46b2fe0dc554f71b61f0bcc8d6afdde2292a6c;p=thirdparty%2Fgcc.git

c-typeck.c (composite_type, [...]): Abort if we have type qualifiers at all.

2004-06-23  Andrew Pinski  <apinski@apple.com>

        * c-typeck.c (composite_type, <case ARRAY_TYPE>): Abort if we have
        type qualifiers at all.
        If both of the type domains are null and the new element type is
        the same as one of the, return the one which the element type.
        matches.
        Do not call qualify_type on the new type.

        * gcc.dg/c90-array-quals-2.c: New test.
