Subject: Remove a FIXME, allowing ++/-- on Complex types (a GCC extension).
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=dd10e02a414c04bff431ba5e749385a91b5480a3;p=clang

Remove a FIXME, allowing ++/-- on Complex types (a GCC extension).

Now, the following test case succeeds...

_Complex double x, y;
void test2(int c) {
  ++x;
}
