Date: Mon, 29 Dec 2008 20:22:00 -0000 [thread overview]
Message-ID: <20081229202047.17920.qmail@sourceware.org> (raw)
In-Reply-To: <bug-38385-14002@http.gcc.gnu.org/bugzilla/>
------- Comment #5 from reichelt at gcc dot gnu dot org 2008-12-29 20:20 -------
Confirmed. Shorter testcase (crashes with "-O -ftree-loop-distribution"):
=====================================
int foo();
void bar()
{
int i, j, x[2], y[2], z[2];
for (i = 0; i < 2; ++i)
if (foo())
{
for (j = 0; j < 2; ++j)
if (z[j])
z[j] = 0;
for (j = 0; j < 2; ++j)
{
x[j] = 0;
y[j] = 0;
}
}
if (x[0] && y[0])
foo();
}
=====================================
