Bug ID: 70137
Summary: internal compiler error: in add_phi_arg_for_new_expr,
at graphite-isl-ast-to-gimple.c:2331
Product: gcc
Version: 6.0
Status: UNCONFIRMED
Keywords: ice-on-valid-code
Severity: normal
Priority: P3
Component: tree-optimization
Assignee: unassigned at gcc dot gnu.org
Reporter: ktkachov at gcc dot gnu.org
CC: spop at gcc dot gnu.org
Target Milestone: ---
The following testcase ICEs for my on aarch64 with ISL 0.15 with -Ofast
-floop-interchange:
int a, b, c, e, f, g;
int d[6];
void
fn1 ()
{
long h;
char i;
for (; g; g++)
{
c = 0;
for (; c <= 5; c++)
{
char *j = (char *)&e;
short *k = (short *)&f;
i = a + g;
h = i ?: b % i;
*j = h;
*k ^= d[c];
}
}
}
