*	Restrict machine cse to really trivial coalescing. Leave the heavy lifting ↵	Evan Cheng	2010-03-08	1	-0/+3
\| \| \| \| \| \|	to a real coalescer. llvm-svn: 98007
*	Don't update physical register def.	Evan Cheng	2010-03-06	1	-2/+3
\| \| \| \|	llvm-svn: 97861
*	Avoid cse load instructions unless they are known to be invariant loads.	Evan Cheng	2010-03-04	1	-10/+36

*	Look ahead a bit to determine if a physical register def that is not marked ↵	Evan Cheng	2010-03-04	1	-6/+61
\| \| \| \| \| \|	dead is really alive. This is necessary to catch a lot of common cse opportunities for targets like x86. llvm-svn: 97706
*	Fix a logic error. An instruction that has a live physical register def ↵	Evan Cheng	2010-03-03	1	-2/+5
\| \| \| \| \| \|	cannot be CSE'ed, but it can be used to replace a common subexpression. llvm-svn: 97688
*	Re-apply r97667 but with a little bit of thought put into the patch. This ↵	Evan Cheng	2010-03-03	1	-65/+3
\| \| \| \| \| \|	implements a special DenseMapInfo trait for DenseMap<MachineInstr*> that compare the value of the MachineInstr rather than the pointer value. Since the hashing and equality test functions ignore defs it's useful for doing CSE kind optimization. llvm-svn: 97678
*	Revert 97667. It broke a bunch of tests.	Dan Gohman	2010-03-03	1	-0/+63
\| \| \| \|	llvm-svn: 97673
*	Move DenseMapInfo for MachineInstr* to MachineInstr.h	Evan Cheng	2010-03-03	1	-63/+0

*	Machine CSE work in progress. It's doing some CSE now. But implicit def of ↵	Evan Cheng	2010-03-03	1	-24/+61
