Removes the _gfortran_size0 calls from the loop but I have not yet located the
doubling up of calls here:

D.1552 = a;
D.1553
static double inv_J(double a[][2])
{
int i, j;
double det = 0.0;
for (j=0; j2; ++j)
det += a[j][0] + a[j][1];
return det;
}
double foo()
{
double mat[2][2];
mat[0][0] = 0.0;
mat[0][1] = 1.0;
mat[1][0] = 2.0;
mat[1][1] = 3.0;
return inv_J(mat);

Any recommendation on how to work around it with GCC 4.3.2? Seemingly
unrelated code changes make it go away. Thanks - Chris.
Add -fno-if-conversion should work.

{
return a != b;
}
int bar(int a, unsigned b)
{
return (unsigned)a != b;

int foobar(int a, unsigned b)

This is because the enum gets a different alias set than unsigned int. We can
do two things:
- reject the vectype. This is difficult because we see different vectypes
for both stores.
- massage the access
