Dominator‐tree type from the IR context.

FunctionT

Function type from the IR context.

InstructionT

Instruction type from the IR context.

TemporalDivergenceTuple

Description

GenericUniformityInfo [constructor]

Constructors

operator=

Move‐assign, taking ownership of the analysis implementation.

compute

Run the uniformity analysis, filling divergence results.

forgetValue

Call before erasing V, or a later instruction reusing its address may be misclassified as uniform.

getCycleInfo

The cycle info this analysis was computed with.

getFunction

The GPU kernel this analysis result is for

getTemporalDivergenceList

Return the list of temporally divergent (value, use, cycle) tuples.

hasDivergentTerminator

Return true if block B's terminator is divergent.

isDivergentAtDef

Whether V is divergent at its definition.

isDivergentAtUse

Whether U is divergent at its use. Uses of a uniform value can be divergent.

isDivergentTerminator

Return true if terminator I has a divergent controlling condition.

isUniformAtDef

Whether V is uniform/non‐divergent at its definition.

isUniformAtUse

Whether U is uniform/non‐divergent at its use.

isUniformTerminator

Return true if terminator I has a uniform controlling condition.

print

T helper function for printing.
