...ase, like: ParentRegion, SubRegions, Blocks, getRegionDepth(), getExitBlock(), getExitingBlock() ...... so, could us just treat "Loop" as some kind of general "Region" of BasicBlocks, and make Loop and Region inherit from "RegionBase"?

...odebase. Quite true. Note that, in general, there are reasonable comments and descriptions of each interface at the top of each header file. I don't think that doxygen picks these descriptions up, so it might be good to look there. For example, contrast this: http://llvm.cs.uiuc.edu/doxygen/LoopInfo_8h-source.html to this: http://llvm.cs.uiuc.edu/doxygen/classllvm_1_1Loop.html > As an example, consider this code: > > %tmp.1 = setgt int %i, 0 > br bool %tmp.1, label %then.0, label %else.0 > > It appears that Value* that corresponds to the %tmp.1 operand of the second...

Hello, is there any documentation for LLVM codebase other than produced by doxygen? The reason I'm asking is that doxygen docs are (1) not very complete at the moment, as lot of classes don't even have a description (2) is generally not the best way to get high-level view of a big codebase. As an example, consider this code: %tmp.1 = setgt int %i, 0 br bool %tmp.1, label

...ts me from using this method for changing the loop. I suggest creating another method for returning the 'cmp' instruction. The new getTripCount implementation will use the new method. Do y'all think that it's a good idea and accept a patch ?

I appreciate your suggestions, some follow-up questions though.... >1) LLVM has the capabilities to do everything that you are trying to >re-implement. >2) Have you looked at the C backend? It recreates loops. It may not >create "for" loops but you can hack on it to do that. I wonder if you mean "goto elimination technique" by Ana Maria Erosa (
