\| \| \| \| \| \| \| \| \|	so that I can (someday) call SE->getSCEV without complaint. No semantic change intended. Patch from Preston Briggs <preston.briggs@gmail.com>. llvm-svn: 168391

*	DependenceAnalysis: Don't crash if there is no constant operand.	Benjamin Kramer	2012-10-31	1	-3/+4

*	dependence analysis	Sebastian Pop	2012-10-11	1	-0/+3781
	Patch from Preston Briggs <preston.briggs@gmail.com>. This is an updated version of the dependence-analysis patch, including an MIV test based on Banerjee's inequalities. It's a fairly complete implementation of the paper Practical Dependence Testing Gina Goff, Ken Kennedy, and Chau-Wen Tseng PLDI 1991 It cannot yet propagate constraints between coupled RDIV subscripts (discussed in Section 5.3.2 of the paper). It's organized as a FunctionPass with a single entry point that supports testing for dependence between two instructions in a function. If there's no dependence, it returns null. If there's a dependence, it returns a pointer to a Dependence which can be queried about details (what kind of dependence, is it loop independent, direction and distance vector entries, etc). I haven't included every imaginable feature, but there's a good selection that should be adequate for supporting many loop transformations. Of course, it can be extended as necessary. Included in the patch file are many test cases, commented with C code showing the loops and array references. llvm-svn: 165708
