Member Data Documentation

◆ EnableMinSize

bool llvm::CombinerInfo::EnableMinSize

Whether we're optimizing for minsize (-Oz).

Definition at line 51 of file CombinerInfo.h.

◆ EnableOpt

bool llvm::CombinerInfo::EnableOpt

Whether optimizations should be enabled.

This is to distinguish between uses of the combiner unconditionally and only when optimizations are specifically enabled/

Definition at line 47 of file CombinerInfo.h.

◆ EnableOptSize

bool llvm::CombinerInfo::EnableOptSize

Whether we're optimizing for size.

Definition at line 49 of file CombinerInfo.h.

◆ IllegalOpsAllowed

bool llvm::CombinerInfo::IllegalOpsAllowed

If IllegalOpsAllowed is false, the CombinerHelper will make use of the legalizerInfo to check for legality before each transformation.

Definition at line 37 of file CombinerInfo.h.

◆ LegalizeIllegalOps

bool llvm::CombinerInfo::LegalizeIllegalOps

If LegalizeIllegalOps is true, the Combiner will also legalize the illegal ops that are created.

◆ LInfo

const LegalizerInfo* llvm::CombinerInfo::LInfo

Definition at line 42 of file CombinerInfo.h.

◆ MaxIterations

unsigned llvm::CombinerInfo::MaxIterations = 0

The maximum number of times the Combiner will iterate over the MachineFunction.

Setting this to 0 enables fixed-point iteration.
