Member Data Documentation

◆ CarriedHeaderPHI

PHINode* llvm::LoopSplitUtils::SplitState::EscapingValue::CarriedHeaderPHI = nullptr

The carried header PHI in partition 0, or null if Def needs no per-partition start value seeded.

Definition at line 103 of file LoopSplitUtils.cpp.

◆ Def

Value* llvm::LoopSplitUtils::SplitState::EscapingValue::Def = nullptr

The value as it exists in partition 0 (the original).

◆ EscapesOutside

bool llvm::LoopSplitUtils::SplitState::EscapingValue::EscapesOutside = false

True if Def is used outside the loop and must be merged at the final exit.
