struct AvailableValueInBlock

Declaration

struct AvailableValueInBlock { /* full declaration omitted */ };

Description

Represents an AvailableValue which can be rematerialized at the end of the associated BasicBlock.

Declared at: llvm/lib/Transforms/Scalar/GVN.cpp:270

Member Variables

public llvm::BasicBlock* BB = nullptr

BB - The basic block in question.

public llvm::gvn::AvailableValue AV

AV - The actual available value

Methods

¶llvm::Value* MaterializeAdjustedValue(
    llvm::LoadInst* Load,
    llvm::GVNPass& gvn) const

Description

Emit code at the end of this block to adjust the value defined here to the specified type. This handles various coercion cases.
