--- Comment #14 from Andrew Pinski <pinskia at gcc dot gnu.org> ---

One more testcase:
void foo (void);
void bar (void);
int g(int, int);
int
test (int a)
{
int r;
if (r = -a)
foo ();
else
bar ();
return g(a,r);
}
---- CUT ----
LLVM is able to move the -a past the if statement still.
So it is not as simple as a single usage either for LLVM.
