verifyBlocksInRegion()

static void verifyBlocksInRegion ( const VPRegionBlock *  Region )

static

Helper function that verifies the CFG invariants of the VPBlockBases within Region.

Checks in this function are generic for VPBlockBases. They are not specific for VPBasicBlocks or VPRegionBlocks.

verifyRegion()

static void verifyRegion ( const VPRegionBlock *  Region )

static

Verify the CFG invariants of VPRegionBlock Region and its nested VPBlockBases.

Do not recurse inside nested VPRegionBlocks.

verifyRegionRec()

static void verifyRegionRec ( const VPRegionBlock *  Region )

static

Verify the CFG invariants of VPRegionBlock Region and its nested VPBlockBases.

Recurse inside nested VPRegionBlocks.
