Member Function Documentation

getPriority()

virtual unsigned llvm::RegAllocPriorityAdvisor::getPriority ( const LiveInterval & LI ) const

pure virtual

Find the priority value for a live range.

A float value is used since ML prefers it.

Implemented in llvm::MLPriorityAdvisor.

References Indexes, and RA.
