Member Function Documentation

◆ collectPotentiallyDeadInstrs()

void llvm::sandboxir::VecUtils::DeadInstructionMorgue::collectPotentiallyDeadInstrs ( ArrayRef< Value * > Bndl )

Record instructions in Bndl that may be dead after vectorization.

For load/store bundles, also record non-first-lane pointer operands; the first lane's pointer is skipped because the vector load/store reuses it. Erased later by tryEraseDeadInstrs().

◆ tryEraseDeadInstrs()

void llvm::sandboxir::VecUtils::DeadInstructionMorgue::tryEraseDeadInstrs ( )
