which generates IR without a llvm.trap function All the normal CI generated this: ``` ret i32 %1 } ; Function Attrs: cold noreturn nounwind memory(inaccessiblemem: write) declare void @llvm.trap() #1 attributes #0 = { "frame-pointer"= ``` But the test-simulator CI doesn't for some reason, so just check for the closing brace instead.
