Kristof Beyls 789efbad2a Fix constant folding through bitcasts by no longer relying on undefined behaviour (converting NaN values between float and double). 
SelectionDAG::getConstantFP(double Val, EVT VT, bool isTarget);
should not be used when Val is not a simple constant (as the comment in
SelectionDAG.h indicates). This patch avoids using this function
when folding an unknown constant through a bitcast, where it cannot be
guaranteed that Val will be a simple constant.

include Add a function computeRegisterLiveness() to MachineBasicBlock. This uses analyzePhysReg() from r163694 to heuristically try and determine the liveness state of a physical register upon arrival at a particular instruction in a block. 2012-09-12 10:18:23 +00:00
