Hi Jakub,
You recently added gcc.c-torture/compile/pr35318.c to the gcc
testsuite. This has introduced a new group of failures for the m32c
port because of this error message:

This is the beta release of binutils 2.19.51.0.2 for Linux, which is

The issue is that GCC does not figure that global cannot point to
local so it does not optimize away
Thanks,
Sorry, but I don't understood - is it impossible to fix, so there are
no needs in bug report?
Or PR about this issue already exists?
Or it's not a bug?

NONLOCAL = NONLOCAL
