@vfdff I have uploaded your patch and ran the LIT test on windows. It's failing
mostly because the //CHECK lines you have in your LIT test are Linux's output.
What you are interested by is the tbaa metada at the call of `expf` right? So
it's enough to just put that check line.
This test is passing for me on Windows (**I didn't test it on Linu**x. Can you
do that?):
