Functions

static void stripValuesNotDefiningMask (unsigned Reg, LiveInterval::SubRange &SR, LaneBitmask LaneMask, const SlotIndexes &Indexes, const TargetRegisterInfo &TRI, unsigned ComposeSubRegIdx)
 For each VNI in SR, check whether or not that value defines part of the mask describe by LaneMask and if not, remove that value from SR.
