--- Comment #21 from Richard Biener <rguenth at gcc dot gnu.org> ---
Btw, the code for the global variable case is now exactly the same as for
int foo(int a) {
if(++a) ++a;
return a;
}
besides the load/store instead of the argument/return, so the bug isn't
about global variables anymore but about optimization obfuscating the
if (++a) ++a; sequence in a way that results in worse code than when
literally translating stmt-at-a-time.
