Detailed Description

Diagnostic information for missed-optimization remarks.

Constructor & Destructor Documentation

◆ OptimizationRemarkMissed() [1/3]

OptimizationRemarkMissed::OptimizationRemarkMissed	(	const char *	PassName,
		StringRef	RemarkName,
		const DiagnosticLocation &	Loc,
		const Value *	CodeRegion
	)

PassName is the name of the pass emitting this diagnostic.

If this name matches the regular expression given in -Rpass-missed=, then the diagnostic will be emitted. RemarkName is a textual identifier for the remark (single-word, camel-case). Loc is the debug location and CodeRegion is the region that the optimization operates on (currently only block is supported).

Definition at line 316 of file DiagnosticInfo.cpp.

◆ OptimizationRemarkMissed() [2/3]

OptimizationRemarkMissed::OptimizationRemarkMissed	(	const char *	PassName,
		StringRef	RemarkName,
		const Instruction *	Inst
	)

Same as above but Inst is used to derive code region and debug location.

Definition at line 323 of file DiagnosticInfo.cpp.

◆ OptimizationRemarkMissed() [3/3]

OptimizationRemarkMissed::OptimizationRemarkMissed	(	const char *	PassName,
		StringRef	RemarkName,
		const Function *	F
	)

Same as above but F is used to derive code region and debug location.
