static bool BBHasFallthrough ( MachineBasicBlock *  MBB )

static

Return true if the specified basic block can fallthrough into the block immediately after it.

static unsigned UnknownPadding ( unsigned  LogAlign, unsigned  KnownBits  )

inlinestatic

Return the worst case padding that could result from unknown offset bits. This does not include alignment padding caused by known offset bits.

Parameters

LogAlign	log2(alignment)
KnownBits	Number of known low offset bits.
