Not even by selectively applying __attribute__((target ("optimize-swaps")))
or __attribute__((target ("no-optimize-swaps"))) (if that is supported in
target directives) to bisect where it matters?

Problem is an invalid swap removal in:
bool boost::test_tools::tt_detail::report_assertion(const
boost::test_tools::as\
sertion_result&, const boost::unit_test::lazy_ostream&,
boost::unit_test::const\
_string, std::size_t, boost::test_tools::tt_detail::tool_level,
boost::test_too\
ls::tt_detail::check_type, std::size_t, ...)
Something going on with subreg handling.

The logic to avoid subregs of TImode wasn't getting executed. I have a patch
that fixes this; doing regression testing and then will get it submitted to the
list. Still working in the background on reducing the test case. :/

BTW I get:

--- Comment #7 from Bill Schmidt <wschmidt at gcc dot gnu.org> ---
Yes, this is unrelated and not really a problem. Something has caused us to
recently start spilling a couple of nonvolatile vector registers to the stack
for this test case, resulting in the failure. I'm going to look into why this
occurred (introduced on 2/13).
