; This file verifies the behavior of the OptBisect class, which is used to
; diagnose optimization related failures. The tests check various
; invocations that result in different sets of optimization passes that
; are run in different ways.
;
; Because the exact set of optimizations that will be run is expected to
; change over time, the checks for disabling passes are written in a
; conservative way that avoids assumptions about which specific passes
; will be disabled.
