struct DivRemPairWorklistEntry

Declaration

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

Description

A thin wrapper to store two values that we matched as div-rem pair. We want this extra indirection to avoid dealing with RAUW'ing the map keys.

Declared at: llvm/lib/Transforms/Scalar/DivRemPairs.cpp:76

Member Variables

public AssertingVH<llvm::Instruction> DivInst

The actual udiv/sdiv instruction. Source of truth.

public AssertingVH<llvm::Instruction> RemInst

The instruction that we have matched as a remainder instruction. Should only be used as Value, don't introspect it.
