Detailed Description

Generic LiveDebugValues pass.

Calls through to VarLocBasedLDV or InstrRefBasedLDV to perform location propagation, via the LDVImpl base class.

Member Typedef Documentation

◆ FragmentOfVar

Types for recording sets of variable fragments that overlap.

For a given local variable, we record all other fragments of that variable that could overlap it, to reduce search time.

Definition at line 617 of file InstrRefBasedImpl.h.

◆ OverlapMap

Definition at line 619 of file InstrRefBasedImpl.h.

Member Function Documentation

◆ getAnalysisUsage()

void LiveDebugValues::getAnalysisUsage ( AnalysisUsage AU) const
inlineoverridevirtual

getAnalysisUsage - Subclasses that override getAnalysisUsage must call this.

For MachineFunctionPasses, calling AU.preservesCFG() indicates that the pass does not modify the MachineBasicBlock CFG.

Reimplemented from llvm::MachineFunctionPass.

Definition at line 73 of file LiveDebugValues.cpp.
