applyDisable()

static IdentifyingPassPtr applyDisable ( IdentifyingPassPtr  PassID, bool  Override  )

static

Allow standard passes to be disabled by command line options.

This supports simple binary flags that either suppress the pass or do nothing. i.e. -disable-mypass=false has no effect. These should be converted to boolOrDefault in order to use applyOverride.

overridePass()

static IdentifyingPassPtr overridePass ( AnalysisID  StandardID, IdentifyingPassPtr  TargetID  )

static

Allow standard passes to be disabled by the command line, regardless of who is adding the pass.

StandardID is the pass identified in the standard pass pipeline and provided to addPass(). It may be a target-specific ID in the case that the target directly adds its own pass, but in that case we harmlessly fall through.

TargetID is the pass that the target has configured to override StandardID.

StandardID may be a pseudo ID. In that case TargetID is the name of the real pass to run. This allows multiple options to control a single pass depending on where in the pipeline that pass is added.
