2016-03-28	Introduce MachineFunctionProperties and the AllVRegsAllocated property	Derek Schuff	1	-0/+5
	MachineFunctionProperties represents a set of properties that a MachineFunction can have at particular points in time. Existing examples of this idea are MachineRegisterInfo::isSSA() and MachineRegisterInfo::tracksLiveness() which will eventually be switched to use this mechanism. This change introduces the AllVRegsAllocated property; i.e. the property that all virtual registers have been allocated and there are no VReg operands left. With this mechanism, passes can declare that they require a particular property to be set, or that they set or clear properties by implementing e.g. MachineFunctionPass::getRequiredProperties(). The MachineFunctionPass base class verifies that the requirements are met, and handles the setting and clearing based on the delcarations. Passes can also directly query and update the current properties of the MF if they want to have conditional behavior. This change annotates the target-independent post-regalloc passes; future changes will also annotate target-specific ones.

2016-03-25	Consider regmasks when computing register-based DBG_VALUE live ranges	Reid Kleckner	1	-7/+23
	Now register parameters that aren't saved to the stack or CSRs are considered dead after the first call. Previously the debugger would show whatever was in the register. Fixes PR26589 Reviewers: aprantl Differential Revision: http://reviews.llvm.org/D17211 llvm-svn: 264429
2016-01-10	Speed up LiveDebugValues	Daniel Berlin	1	-28/+52
	Summary: Use proper dataflow ordering to speed convergence. This will converge the testcase on bug 26055 in 2 iterations. (data structures speedups to come to make even that faster) Reviewers: kcc, samsonov, echristo, dblaikie, tvvikram Subscribers: llvm-commits Differential Revision: http://reviews.llvm.org/D16039 llvm-svn: 257292
