[LLVMdev] How to gather data dependences
...ning all these passes (-basicaa -mem2reg -simplifycfg -loop-simplify -loop-rotate -simplifycfg -instcombine -indvars -da) helped a lot, but now i'm unable to find dependencies that are outside of the loop. f.eg. code like this returns no dependencies (and no store/load instruction at all). int nonLoopDep( int A, int B, int C ) { A = B + C; B = A / C; return B; } I've figured out that removing -mem2reg and -instcombine helps a little but it reports more dependencies than it should and also it messes up looking for dependencies inside loops completly. -------------- next part -------...

DA exists to support building a dependence graph. It checks to see if two instructions
