*	Change LBH_TAKEN_WEIGHT to 124 (from 128). Right now, sum of	Jakub Staszak	2011-07-28	1	-4/+4
\| \| \| \| \| \| \|	LBH_TAKEN_WEIGHT + LBH_NONTAKEN_WEIGHT = 128 which in _most_ cases reduce number of rounding errors. llvm-svn: 136428
*	Heuristics are in descending priority now. If we use one of them, skip the rest.	Jakub Staszak	2011-07-28	1	-13/+23
\| \| \| \|	llvm-svn: 136402
*	Add InEdges (edges from header to the loop) in Loop Branch Heuristics, so	Jakub Staszak	2011-07-28	1	-0/+17
\| \| \| \| \| \| \|	there is no frequency difference whether condition is in the header or in the latch. llvm-svn: 136398
*	Remove "LoopInfo.h" include from BranchProbabilityInfo.h.	Jakub Staszak	2011-07-16	1	-0/+5
\| \| \| \|	llvm-svn: 135353
*	Fix pointer heuristic. Check whether predicator is ICMP_NE instead of if it is	Jakub Staszak	2011-07-15	1	-2/+2
\| \| \| \| \| \|	not isEquality(). llvm-svn: 135296
*	Calculate backedge probability correctly.	Jakub Staszak	2011-06-23	1	-24/+0
\| \| \| \|	llvm-svn: 133776
*	Introduce BlockFrequency analysis for BasicBlocks.	Jakub Staszak	2011-06-23	1	-0/+24
\| \| \| \|	llvm-svn: 133766
*	Introduce MachineBranchProbabilityInfo class, which has similar API to	Jakub Staszak	2011-06-16	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
*	Move class into an anonymous namespace.	Benjamin Kramer	2011-06-13	1	-1/+2
\| \| \| \|	llvm-svn: 132925
*	Branch profiling: floating-point avoidance.	Andrew Trick	2011-06-11	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
*	Fold assert-only-used variable into the assert.	Nick Lewycky	2011-06-04	1	-2/+1
\| \| \| \|	llvm-svn: 132620
*	Missing include of climits in the new BranchProbability pass.	Andrew Trick	2011-06-04	1	-0/+1
\| \| \| \|	llvm-svn: 132616
*	New BranchProbabilityInfo analysis. Patch by Jakub Staszak!	Andrew Trick	2011-06-04	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
