; This test verifies that no optimizations are performed on the @f function
; when the -opt-bisect-limit=0 option is used. In particular, the X86
; instruction selector will optimize the cmp instruction to a sub instruction
; if it is not run in -O0 mode.
; RUN: llc -O3 -opt-bisect-limit=0 -o - %s | FileCheck %s
