; 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.
