*	Fix a bug introduced by my previous patch. With this change, SPEC is now ↵	Owen Anderson	2008-11-18	1	-1/+1
\| \| \| \| \| \|	clean with prealloc splitting enabled. llvm-svn: 59544
*	Don't allow the restore point to be placed after terminators. With this change,	Owen Anderson	2008-11-13	1	-2/+2
\| \| \| \| \| \| \|	MultiSource/Applications is clean with the prealloc splitter. Some failures remain in SPEC. llvm-svn: 59267
*	Don't walk into predecessors in which the vreg is not live when doing ↵	Owen Anderson	2008-11-11	1	-0/+2
\| \| \| \| \| \| \| \|	shrinkwrapping. This lets several failing tests get farther along, but doesn't completely fix any of them. llvm-svn: 59086
*	Use the new predicate to control when we do prealloc splitting. Fix a small ↵	Owen Anderson	2008-11-05	1	-1/+5
\| \| \| \| \| \|	bug. llvm-svn: 58738
*	First pass at checking for the creation of a new join point when doing ↵	Owen Anderson	2008-11-04	1	-0/+73
\| \| \| \| \| \|	pre-alloc splitting. This is not turned on yet. llvm-svn: 58726
*	Revert my last patch until I consult with Evan about it.	Owen Anderson	2008-11-03	1	-10/+0
\| \| \| \|	llvm-svn: 58591
*	Don't do pre-splitting if doing so would create a value join that did not	Owen Anderson	2008-11-02	1	-0/+10
\| \| \| \| \| \| \| \| \|	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. llvm-svn: 58560
*	Add a fixme.	Evan Cheng	2008-10-31	1	-0/+3
\| \| \| \|	llvm-svn: 58514
*	- More pre-split fixes: spill slot live interval computation bug; restore ↵	Evan Cheng	2008-10-29	1	-38/+93
\| \| \| \| \| \| \| \|	point bug. - If a def is spilt, remember its spill index to allow its reuse. llvm-svn: 58375
*	- Rewrite code that update register live interval that's split.	Evan Cheng	2008-10-29	1	-81/+152
\| \| \| \| \| \| \|	- Create and update spill slot live intervals. - Lots of bug fixes. llvm-svn: 58367
*	If def is in the same mbb as the barrier, spilt the value after the last use ↵	Evan Cheng	2008-10-28	1	-8/+18
\| \| \| \| \| \|	before the barrier. llvm-svn: 58314
*	Add command line option to limit the number splits to help debugging.	Evan Cheng	2008-10-28	1	-3/+7
\| \| \| \|	llvm-svn: 58312
*	Avoid putting a split past the end of the live range; always shrink wrap ↵	Evan Cheng	2008-10-28	1	-11/+20
\| \| \| \| \| \|	live interval in the barrier mbb. llvm-svn: 58309
*	Silence a bogus compile time warning.	Evan Cheng	2008-10-27	1	-1/+1
\| \| \| \|	llvm-svn: 58297
*	Remove val# defined by a remat'ed def that is now dead.	Evan Cheng	2008-10-27	1	-0/+3
\| \| \| \|	llvm-svn: 58294
*	For now, don't split live intervals around x87 stack register barriers. ↵	Evan Cheng	2008-10-27	1	-0/+2
\| \| \| \| \| \|	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. llvm-svn: 58230
*	Do not shrink wrap live interval in a mbb if it's livein any of its ↵	Evan Cheng	2008-10-26	1	-6/+21
\| \| \| \| \| \|	successor blocks. The mbb can be revisited again after all of the successors are processed. llvm-svn: 58184
*	Handle cases where there aren't uses in the barrier mbb.	Evan Cheng	2008-10-25	1	-1/+5
\| \| \| \|	llvm-svn: 58174
*	If val# def is ~0U, meaning it's defined by a PHI, and it's previously ↵	Evan Cheng	2008-10-25	1	-9/+11
\| \| \| \| \| \|	split, spill before the barrier because it's impossible to determine if all the defs are spilled in the same spill slot. llvm-svn: 58129
*	Fix a pasto.	Evan Cheng	2008-10-24	1	-1/+1
\| \| \| \|	llvm-svn: 58102
*	Fix a end() dereference; remove an abort() that wasn't meant to be left in.	Evan Cheng	2008-10-24	1	-5/+4
\| \| \| \|	llvm-svn: 58072
*	Avoid splitting an interval multiple times; avoid splitting ↵	Evan Cheng	2008-10-24	1	-51/+106
\| \| \| \| \| \|	re-materializable val# (for now). llvm-svn: 58068
*	Committing a good chunk of the pre-register allocation live interval ↵	Evan Cheng	2008-10-23	1	-12/+571
\| \| \| \| \| \|	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. llvm-svn: 58044
*	Add skeleton for the pre-register allocation live interval splitting pass.	Evan Cheng	2008-10-20	1	-0/+81
