◆ getAnalysisUsage()

void llvm::SPIRVMergeRegionExitTargets::getAnalysisUsage ( AnalysisUsage ) const
inlineoverridevirtual

getAnalysisUsage - This function should be overriden by passes that need analysis information to do their job.

If a pass specifies that it uses a particular analysis result to this function, it can then use the getAnalysis<AnalysisType>() function, below.

Reimplemented from llvm::Pass.

◆ runOnConvergenceRegion()

bool llvm::SPIRVMergeRegionExitTargets::runOnConvergenceRegion ( LoopInfo LI,
const SPIRV::ConvergenceRegion CR

inline

Run the pass on the given convergence region and sub-regions (DFS).

Returns true if a region/sub-region was modified, false otherwise. This returns as soon as one region/sub-region has been modified.
