Clang trunk ICE (Assertion `Removed && "Register is not used by this instruction!) #28675
Comments
assigned to @MatzeB |
This seems to be a regression from 3.8. +matze because the assert says "register" ;-) |
I cannot reproduce. This could have to do with the contents of valarray or the target triple used. Could you run
and attach the resulting crash.ll to the bugreport? |
IR repro

It still does not reproduce on ToT for me. I will try the 3.9 branch. |
Ups, the crash.ll I used was the one I previously created myself, my browser safed the actual reproducer from this ticket as crash-2.ll and that one reproduces even on ToT. |
Fixed in r278086. I am pretty sure the problem existed since 2013. Probably triggered by an unrelated change if this specific example only crashed in 3.9. |
mentioned in issue #28974 |
