2011-07-15	Fix pointer heuristic. Check whether predicator is ICMP_NE instead of if it is	Jakub Staszak	1	-2/+2

2011-06-23	Calculate backedge probability correctly.	Jakub Staszak	1	-24/+0

2011-06-23	Introduce BlockFrequency analysis for BasicBlocks.	Jakub Staszak	1	-0/+24
	llvm-svn: 133766
2011-06-16	Introduce MachineBranchProbabilityInfo class, which has similar API to	Jakub Staszak	1	-1/+1
	BranchProbabilityInfo (expect setEdgeWeight which is not available here). Branch Weights are kept in MachineBasicBlocks. To turn off this analysis set -use-mbpi=false. llvm-svn: 133184
2011-06-13	Move class into an anonymous namespace.	Benjamin Kramer	1	-1/+2
	llvm-svn: 132925
2011-06-11	Branch profiling: floating-point avoidance.	Andrew Trick	1	-54/+63
	Patch by: Jakub Staszak! Introduces BranchProbability. Changes unsigned to uint32_t all over and uint64_t only when overflow is expected. llvm-svn: 132867
2011-06-04	Fold assert-only-used variable into the assert.	Nick Lewycky	1	-2/+1
	llvm-svn: 132620
2011-06-04	Missing include of climits in the new BranchProbability pass.	Andrew Trick	1	-0/+1
	llvm-svn: 132616
2011-06-04	New BranchProbabilityInfo analysis. Patch by Jakub Staszak!	Andrew Trick	1	-0/+348
	BranchProbabilityInfo provides an interface for IR passes to query the likelihood that control follows a CFG edge. This patch provides an initial implementation of static branch predication that will populate BranchProbabilityInfo for branches with no external profile information using very simple heuristics. It currently isn't hooked up to any external profile data, so static prediction does all the work. llvm-svn: 132613
