getInstructions()

ArrayRef< UniqueInst > llvm::mca::CircularSourceMgr::getInstructions ( ) const

inlineoverridevirtual

Provides a fixed range of UniqueInst to iterate.

Implements llvm::mca::SourceMgr.

Definition at line 69 of file SourceMgr.h.

getNumIterations()

unsigned llvm::mca::CircularSourceMgr::getNumIterations ( ) const

Definition at line 71 of file SourceMgr.h.

hasNext()

bool llvm::mca::CircularSourceMgr::hasNext ( ) const

inlineoverridevirtual

Whether there is any SourceRef to inspect / peek next.

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

isEnd()

bool llvm::mca::CircularSourceMgr::isEnd ( ) const

inlineoverridevirtual

Whether the instruction stream has eneded.

Implements llvm::mca::SourceMgr.

References hasNext().

peekNext()

SourceRef llvm::mca::CircularSourceMgr::peekNext ( ) const

inlineoverridevirtual

The next SourceRef.

Implements llvm::mca::SourceMgr.
