------- Comment #3 from jakub at gcc dot gnu dot org 2009-04-23 08:45 -------
Simplified testcase (ICEs with both C and C++ FEs):
extern double pow (double, double);
extern double fabs (double);
void foo (double *);
void bar (double *);
static double
baz (double x, double e)
{
if ((int) e == 1)
return x;
return pow (x, e);
}
void
test (double *x, double *y)
{
double P[3], r;
bar (P);
if (P[2] != 0)
baz (fabs (P[2]), y[2]);
if (fabs (P[0]) > fabs (P[1]))
r = baz (fabs (P[1] / P[0]), y[0]);
if (P[2])
P[2] *= (1 + r);
foo (x);
}
