Questions about jump threading optimization and what we can do
Since the bug report here: https://bugs.llvm.org/show_bug.cgi?id=44679 I've
been thinking about cases like it, such as: https://godbolt.org/z/Fwq8mn
I wonder what we can do about this in a general sense. As far as I can
tell, the jump threading algorithm is *really* conservative, which is one
reason this isn't working as well as I'd hope; however, we don't want to
produce irreducible control flow that the other passes would work le...
