Member Function Documentation

getInstructions()

virtual ArrayRef< UniqueInst > llvm::mca::SourceMgr::getInstructions ( ) const

pure virtual

Provides a fixed range of UniqueInst to iterate.

Implemented in llvm::mca::IncrementalSourceMgr, and llvm::mca::CircularSourceMgr.

Referenced by size().

hasNext()

virtual bool llvm::mca::SourceMgr::hasNext ( ) const

pure virtual

Whether there is any SourceRef to inspect / peek next.

Note that returning false from this doesn't mean the instruction stream has ended.

Implemented in llvm::mca::IncrementalSourceMgr, and llvm::mca::CircularSourceMgr.

isEnd()

virtual bool llvm::mca::SourceMgr::isEnd ( ) const

pure virtual

Whether the instruction stream has eneded.

Implemented in llvm::mca::IncrementalSourceMgr, and llvm::mca::CircularSourceMgr.

Referenced by llvm::mca::EntryStage::hasWorkToComplete().

peekNext()

virtual SourceRef llvm::mca::SourceMgr::peekNext ( ) const

pure virtual

The next SourceRef.

Implemented in llvm::mca::IncrementalSourceMgr, and llvm::mca::CircularSourceMgr.

size()

virtual size_t llvm::mca::SourceMgr::size ( ) const

inlinevirtual

(Fixed) Number of UniqueInst.

Returns the size of getInstructions by default.

Definition at line 37 of file SourceMgr.h.

References getInstructions(), and llvm::ArrayRef< T >::size().

updateNext()

virtual void llvm::mca::SourceMgr::updateNext ( )

pure virtual

Advance to the next SourceRef.

Implemented in llvm::mca::IncrementalSourceMgr, and llvm::mca::CircularSourceMgr.
