LiveRange::Segment LiveIntervals::addSegmentToEndOfBlock ( unsigned  reg,

bool LiveIntervals::checkRegMaskInterference ( LiveInterval LI,
BitVector UsableRegs

checkRegMaskInterference - Test if LI is live across any register mask instructions, and compute a bit mask of physical registers that are not clobbered by any of them.

Returns false if LI doesn't cross any register mask instructions. In that case, the bit vector is not filled in.

void LiveIntervals::extendToIndices ( LiveRange LR,

extendToIndices - Extend the live range of LI to reach all points in Indices. The points in the Indices array must be jointly dominated by existing defs in LI. PHI-defs are added as needed to maintain SSA form.

If a SlotIndex in Indices is the end index of a basic block, LI will be extended to be live out of the basic block.

pruneValue - If an LI value is live at Kill, prune its live range by removing any liveness reachable from Kill. Add live range end points to EndPoints such that extendToIndices(LI, EndPoints) will reconstruct the value's live range.

Calling pruneValue() and extendToIndices() can be used to reconstruct SSA form after adding defs to a virtual register.

void LiveIntervals::releaseMemory ( )
virtual

releaseMemory() - This member can be implemented by a pass if it wants to be able to release its memory when it is no longer needed. The default behavior of passes is to hold onto memory for the entire duration of their lifetime (which is the entire compile time). For pipelined passes, this is not a big deal because that memory gets recycled every time the pass is invoked on another program unit. For IP passes, it is more important to free memory when it is unused.

Optionally implement this function to release pass memory when it is no longer used.

void LiveIntervals::repairIntervalsInRange ( MachineBasicBlock MBB,

repairIntervalsInRange - Update live intervals for instructions in a range of iterators. It is intended for use after target hooks that may insert or remove instructions, and is only efficient for a small number of instructions.

OrigRegs is a vector of registers that were originally used by the instructions in the range between the two iterators.

Currently, the only only changes that are supported are simple removal and addition of uses.

shrinkToUses - After removing some uses of a register, shrink its live range to just the remaining uses. This method does not compute reaching defs for new uses, and it doesn't remove dead defs. Dead PHIDef values are marked as unused. New dead machine instructions are added to the dead vector. Return true if the interval may have been separated into multiple connected components.
