[LLVMdev] [Pass] How to gather data dependencies
Hello,
I'm currently trying to develop new LLVM Pass that will generate simple
data dependencies graph. For now I'm trying to get familiar with
DependenceAnalysis.
My general idea is to traverse each function (runOnFunction) top to
bottom Instruction by Instruction, using DA.depends( I, I2, ...) on
every Instructions combination in function to check if they are
dependent on any

[LLVMdev] How to gather data dependences
Hello, thanks to your advices now my pass is on good way (i hope), but i've
faced one problem that i cannot solve by myself:
Running 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
