2008-11-18	Fix a bug introduced by my previous patch. With this change, SPEC is now ↵	Owen Anderson
	clean with prealloc splitting enabled. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@59544 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-13	Don't allow the restore point to be placed after terminators. With this change,	Owen Anderson
	MultiSource/Applications is clean with the prealloc splitter. Some failures remain in SPEC. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@59267 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-11	Don't walk into predecessors in which the vreg is not live when doing ↵	Owen Anderson
	shrinkwrapping. This lets several failing tests get farther along, but doesn't completely fix any of them. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@59086 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-05	Use the new predicate to control when we do prealloc splitting. Fix a small ↵	Owen Anderson
	bug. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@58738 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-04	First pass at checking for the creation of a new join point when doing ↵	Owen Anderson
	pre-alloc splitting. This is not turned on yet. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@58726 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-03	Revert my last patch until I consult with Evan about it.	Owen Anderson
	git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@58591 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-02	Don't do pre-splitting if doing so would create a value join that did not	Owen Anderson
	exist before. Updating the live intervals in that care is tricky in the general case. Evan, if you see a tighter guard condition for this, let me know. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@58560 91177308-0d34-0410-b5e6-96231b3b80d8
2008-10-31	Add a fixme.	Evan Cheng
	git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@58514 91177308-0d34-0410-b5e6-96231b3b80d8
2008-10-29	- More pre-split fixes: spill slot live interval computation bug; restore ↵	Evan Cheng
	point bug. - If a def is spilt, remember its spill index to allow its reuse. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@58375 91177308-0d34-0410-b5e6-96231b3b80d8
2008-10-29	- Rewrite code that update register live interval that's split.	Evan Cheng
	- Create and update spill slot live intervals. - Lots of bug fixes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@58367 91177308-0d34-0410-b5e6-96231b3b80d8
2008-10-28	If def is in the same mbb as the barrier, spilt the value after the last use ↵	Evan Cheng
	before the barrier. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@58314 91177308-0d34-0410-b5e6-96231b3b80d8
2008-10-28	Add command line option to limit the number splits to help debugging.	Evan Cheng
	git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@58312 91177308-0d34-0410-b5e6-96231b3b80d8
2008-10-28	Avoid putting a split past the end of the live range; always shrink wrap ↵	Evan Cheng
	live interval in the barrier mbb. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@58309 91177308-0d34-0410-b5e6-96231b3b80d8
2008-10-27	Silence a bogus compile time warning.	Evan Cheng
	git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@58297 91177308-0d34-0410-b5e6-96231b3b80d8
2008-10-27	Remove val# defined by a remat'ed def that is now dead.	Evan Cheng
	git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@58294 91177308-0d34-0410-b5e6-96231b3b80d8
2008-10-27	For now, don't split live intervals around x87 stack register barriers. ↵	Evan Cheng
	FpGET_ST0_80 must be right after a call instruction (and ADJCALLSTACKUP) so we need to find a way to prevent reload of x87 registers between them. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@58230 91177308-0d34-0410-b5e6-96231b3b80d8
2008-10-26	Do not shrink wrap live interval in a mbb if it's livein any of its ↵	Evan Cheng
	successor blocks. The mbb can be revisited again after all of the successors are processed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@58184 91177308-0d34-0410-b5e6-96231b3b80d8
2008-10-25	Handle cases where there aren't uses in the barrier mbb.	Evan Cheng
	git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@58174 91177308-0d34-0410-b5e6-96231b3b80d8
2008-10-25	If val# def is ~0U, meaning it's defined by a PHI, and it's previously ↵	Evan Cheng
	split, spill before the barrier because it's impossible to determine if all the defs are spilled in the same spill slot. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@58129 91177308-0d34-0410-b5e6-96231b3b80d8
2008-10-24	Fix a pasto.	Evan Cheng
	git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@58102 91177308-0d34-0410-b5e6-96231b3b80d8
2008-10-24	Fix a end() dereference; remove an abort() that wasn't meant to be left in.	Evan Cheng
	git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@58072 91177308-0d34-0410-b5e6-96231b3b80d8
2008-10-24	Avoid splitting an interval multiple times; avoid splitting ↵	Evan Cheng
	re-materializable val# (for now). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@58068 91177308-0d34-0410-b5e6-96231b3b80d8
2008-10-23	Committing a good chunk of the pre-register allocation live interval ↵	Evan Cheng
	splitting pass. It's handling simple cases and appear to do good things. Next: avoid splitting an interval multiple times; renumber registers when possible; record stack slot live intervals for coloring; rematerialize defs when possible. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@58044 91177308-0d34-0410-b5e6-96231b3b80d8
2008-10-20	Add skeleton for the pre-register allocation live interval splitting pass.	Evan Cheng
	git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@57847 91177308-0d34-0410-b5e6-96231b3b80d8
