The reverse postorder iterator does what you want. It's defined in ADT/PostOrderIterator.h, and is used like this: ReversePostOrderTraversal<Function*> RPOT(&F); for (ReversePostOrderTraversal<Function*>::rpo_iterator RI = RPOT.begin(), RE = RPOT.end(); RI != RE; ++RI) <work here> Creating a ReversePostOrderTraversal is not cheap, because it first has to do a postorder walk of the entire graph.

I'm looking for a way to traverse machine basic blocks in a specific order. Basically I want all blocks that are predecessors to the current block to be traversed before the current block. I've looked at MachineDominatorTree but this doesn't traverse them in quite the way I want them to. Anyone know of a way to do this? Thanks, Micah -------------- next part -------------- An HTML

Hi, Example on how to iterate over CFG, take a look at DominanceFrontier.cpp. You can further implement easily a traverse graph algorithm.

As far as I know, there is none. Pretty much every analysis or transform on EBBs can be extended to work on the dominator tree, which is what LLVM prefers.

Hi LLVM Delveloper, i've been working on LLVM and Clang to get basic block information. The CFG supports Visitors (CFG.h) but i might want to ask that is there any code sample available so that i can get the things easily.. Regards, Kulkarni Ashish A.

Hi all, I am trying to find a sample pass that works on extended basic blocks. Any suggestion or help is very much appreciated. Thanks in advance.

Hi Ankur, > The flags "-view-sched-dags".. described in the doc doesn't seem to work. ( > "llc -help" doesn't list it ). as far as I remember, displaying DAGs during compilation is only enabled in "debug builds" [1] of LLVM. You probably have to re-configure and re-compile LLVM to enable this feature. Best regards, Christoph [1]

I am trying to understand the SelectionDAG construction from LLVM IR. I have gone through the doc "The LLVM Target-Independent Code Generator" on LLVM site. This gives a great initial overview. However I am unable to catch the actual control flow for the llvm->selectionDag conversion. The flags "-view-sched-dags".. described in the doc doesn't seem to work. ( "llc

Hello, I was wondering whether or not some behaviour that I am seeing is expected behaviour and that it has been designed like this, or not. A dominator relation is given by "if A dominates B", then all paths to B go through A. For example, take the CFG below (which is a directed graph (couldn’t make the arrow heads but ok.): A / \ B C \ / D | E We can construct
