I agree with the gcc folks: it's really important to get frame pointer
emission etc aligned across the various compilers. ICC defaulting to
frame pointers off and GCC/llvm defaulting to them on will seriously
warp the numbers. Also, while I agree that compilers should all
optimize undefined behavior away as aggressively as possible, I also
think it's not a very "interesting" test in the grand scheme of
Very interesting work though, I hope to have some time to dive in more
