clang::CIRGen::CIRGenFunction::CapturedCleanups Class Reference

Captures cleanups for variables whose lifetime ends in a region owned by an enclosing op rather than at the end of a cir.cleanup.scope, so that they can be emitted into that region later. More...

Classes
class	CaptureScope
	An RAII class that suppresses cir.cleanup.scope creation for cleanups pushed onto the EH stack while such a variable is being emitted and instead captures these cleanups so that they can be emitted into the owning op's cleanup region later. More...

Public Member Functions
	CapturedCleanups (CIRGenFunction &cgf, bool active)
void	emitIntoCleanupRegion (mlir::Location loc)
	Emit the captured cleanups into the current insertion point, which must be inside the owning op's cleanup region.

Detailed Description

Captures cleanups for variables whose lifetime ends in a region owned by an enclosing op rather than at the end of a cir.cleanup.scope, so that they can be emitted into that region later.

Examples for uses are:

• A loop condition variable's cleanups in the loop op's per-iteration cleanup region.
• Coroutine parameters and promises, which are cleaned up in a separate destroy region
