Ohhhhh, this is an object size regression?  This test seems very fragile.  Jump
threading will alter code size, so any change in the threading rules will
likely have an effect on code size.  I suggest you add -fno-thread-jumps to the
test and adjust the object-size test accordingly.

This is a testsuite regression that must be fixed by the target maintainers,
not a middle-end or tree-optimization regression.  I've marked it as so.

That's why it's better to include actual command lines, and not web pages that
may change after the PR has been created.
