Jakob Stoklund Olesen 0613516b16 Implement the first half of LiveDebugVariables. ... Scan the MachineFunction for DBG_VALUE instructions, and replace them with a data structure similar to LiveIntervals. The live range of a DBG_VALUE is determined by propagating it down the dominator tree until a new DBG_VALUE is found. When a DBG_VALUE lives in a register, its live range is confined to the live range of the register's value. LiveDebugVariables runs before coalescing, so DBG_VALUEs are not artificially extended when registers are joined. The missing half will recreate DBG_VALUE instructions from the intervals when register allocation is complete. The pass is disabled by default. It can be enabled with the temporary command line option -live-debug-variables. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@120636 91177308-0d34-0410-b5e6-96231b3b80d8		2010-12-02 00:37:37 +00:00
