◆ DEBUG_TYPE

#define DEBUG_TYPE "regalloc"

◆ getSubRangeForMask()

Find a subrange corresponding to the lane mask LM, or a superset of it, in the live interval LI.

The interval LI is assumed to contain such a subrange. This function is used to find corresponding subranges between the original interval and the new intervals.
