It is the same issue and the patch posted in
https://gcc.gnu.org/ml/gcc-patches/2015-09/msg00403.html fixes this test-case
too.

Thanks for reporting. This test case is valid for targets that has branch cost
greater than 1.
One way to handle this is by disabling this for convections involving bool that
are part of branch

forwprop propagates:

can_fix_p is returining CODE_FOR_nothing for converting from tomode=V4SImode to
