2009-05-07	Just turn aggressive stack coloring off at -O3.	Bill Wendling
	git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@71140 91177308-0d34-0410-b5e6-96231b3b80d8

2009-05-05	Do not substitute if the new register isn't in the register class of the ↵	Evan Cheng
	operand being updated. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@70953 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-04	Do forward and backward substitution to eliminate loads and stores when ↵	Evan Cheng
	possible. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@70937 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-04	Restore minor deletion.	Mike Stump
	git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@70892 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-03	Typo.	Evan Cheng
	git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@70792 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-03	In some rare cases, the register allocator can spill registers but end up ↵	Evan Cheng
	not utilizing registers at all. The fundamental problem is linearscan's backtracking can end up freeing more than one allocated registers. However, reloads and restores might be folded into uses / defs and freed registers might not be used at all. VirtRegMap keeps track of allocations so it knows what's not used. As a horrible hack, the stack coloring can color spill slots with free registers. That is, it replace reload and spills with copies from and to the free register. It unfold instructions that load and store the spill slot and replace them with register using variants. Not yet enabled. This is part 1. More coming. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@70787 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-26	Enable stack slot coloring DCE. Evan's spiller fixes were needed before ↵	Owen Anderson
	this could happen. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@65501 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-24	Add a debugging option for SSC DCE.	Owen Anderson
	git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@65375 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-20	Add a quick pass to the stack slot colorer to eliminate some trivially ↵	Owen Anderson
	redundant spills after coloring. Ideally these would never get created in the first place, but until we enhance the spiller to have a more global picture of what's happening, this is necessary for code quality in some circumstances. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@65120 91177308-0d34-0410-b5e6-96231b3b80d8
2008-12-05	Teach StackSlotColoring to update MachineMemOperands when	Dan Gohman
	changing the stack slots on an instruction, to keep them consistent with the actual memory addresses. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@60584 91177308-0d34-0410-b5e6-96231b3b80d8
2008-10-15	Adjust whitespace in debug messages to be more consistent	Dan Gohman
	with other debug messages. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@57543 91177308-0d34-0410-b5e6-96231b3b80d8
2008-10-03	Switch the MachineOperand accessors back to the short names like	Dan Gohman
	isReg, etc., from isRegister, etc. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@57006 91177308-0d34-0410-b5e6-96231b3b80d8
2008-09-22	Instead of setPreservesAll, just mark them preseving machine loop info and ↵	Evan Cheng
	machine dominators. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@56475 91177308-0d34-0410-b5e6-96231b3b80d8
2008-09-22	Mark several codegen passes as preserving all analysis.	Evan Cheng
	git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@56469 91177308-0d34-0410-b5e6-96231b3b80d8
2008-09-04	Tidy up several unbeseeming casts from pointer to intptr_t.	Dan Gohman
	git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@55779 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-10	Make stack slot coloring's debug output more consistent with	Dan Gohman
	other passes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53415 91177308-0d34-0410-b5e6-96231b3b80d8
2008-06-23	Remove option used to debug stack coloring bugs. It's no longer needed since ↵	Evan Cheng
	stack coloring is now bug free. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52644 91177308-0d34-0410-b5e6-96231b3b80d8
2008-06-23	Instead of adding an isSS field to LiveInterval to denote stack slot. Use ↵	Evan Cheng
	top bit of 'reg' instead. If the top bit is set, than the LiveInterval represents a stack slot live interval. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52639 91177308-0d34-0410-b5e6-96231b3b80d8
2008-06-04	Add a stack slot coloring pass. Not yet enabled.	Evan Cheng
