--- Comment #10 from Chen Gang <gang.chen.5i5j at gmail dot com> ---
Need use gimple_location(stmt) for it. The stmt is the variable in
gcc/tree-ssa-sccvn.c before call fold_binary(). But unlucky, it is not passed
into fold_binary(), we can not get it directly.
After try a temporary fix, the related output is:
[root@localhost build-gcc-x86_64]# gcc -O2 -Wall -Wextra -c /tmp/i387-tdep.c
when assuming that (X + c) >= X is always true
/tmp/i387-tdep.c: In function âi387_supply_fsaveâ:
/tmp/i387-tdep.c:6:3: warning: assuming signed overflow does not occur when
assuming that (X + c) >= X is always true [-Wstrict-overflow]
for (i = st0_regnum; i < st0_regnum + 16;)
^
I shall try to give a normal fix for it, next.

Better than preliminary
This patch returns the correct code from raw_read and we get the "Is a
directory"
error message as we should. I think this is it. I will regression test and
work up a test case.
