; RUN: opt -simplifycfg -S -o - < %s | FileCheck %s
; This test case was written to trigger an incorrect assert statement in
; -simplifycfg. Thus we don't actually want to check the output, just that
; -simplifycfg ran successfully. Thus we only check that the function still
; exists, and that it still calls foo().
; NOTE: There are some obviously dead blocks and missing branch weight
; metadata. Both of these features were key to triggering the assert.
; Additionally, the not-taken weight of the branch with a weight had to
; be 0 to trigger the assert.
