```
; RUN: llc -mtriple=amdgcn-amd-amdhsa -global-isel < %s
; LLVM ERROR: cannot select: G_UBSANTRAP 0 (in function: ubsan_trap)
define void @ubsan_trap() {
call void @llvm.ubsantrap(i8 0)
ret void
}
```
We already handle G_TRAP and G_DEBUGTRAP. ubsan isn't particularly special and should be able to follow
![]()
