--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
Note gimplification fails because we are evaluating in an lvalue context but
got -_7 in the end. In the past we've hacked around Fortran oddities by
doing tem = -_7 and returning tem here, simply using a temporary as lvalue
which means the value assigned is lost (IIRC for things like assinging to
a literal constant which could happen in parameter context).
Full statement:
-_7 = MEM[(real(kind=4)[3] *)_4][_5]
and .original has
D.3938 = -1;
S.3 = 1;
while (1)
{
if (S.3 > 3) goto L.2;
-z[S.3 + -1] = (*(real(kind=4)[3] * restrict) atmp.0.data)[S.3 +
D.3938];
S.3 = S.3 + 1;
}
L.2:;
