The patch below basically hammers out some ideas as to where I'd like to take the passmanager in LLVM. I've tried thinking things through, but I'm still a n00b, so some criticism would be more than welcome. =) Starting from line 191 down. If you're wondering why I created a patch, well that's because I found thinking in passmanagert.h the most productive. -- Regards.

...problem as I see it. We want to be able to manage the way passes traverse things, in particular a module's worth of functions. As was in your example, we want inliner and mem2reg calls interleaved, as we traverse functions in callgraphscc order. More generally, we want the ability to specify traversals. And specify passes that should use these traversals. Currently, when you tell a function pass to go to work on a module, it iterates through the module, as it pleases. Now, this behaviour is fine, but insufficient. What we want is the ability to say, function pass, "run on traversal"...

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

How can one measure the effect of NAT traversal packet loss? We currently have no solution for NAT traversal for our SIP clients. There is no doubt that packets are getting lost. What is not clear is how much damage this does. On the face of it, everything seems fine. Could this be so? Perhaps we're suffering a degradation in quality or our call setup times could be improved. How can we

Hi, I am trying to sum column information in a list with 3 instances. For example: ID Traversed ID Traversed ID Traversed 1 5 1 7 1 8 2 8 2 11 2 7 3 11 3 22 3 16 What I want to do is sum the

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

Hi, I am some difficulty in traversing and quering about selectionDAG. One great way of doing it is through Dot as described in the docs. However, in my case the llvm source code is installed on a remote linux machine and I am accessing it through a Windows PC. So the "popping out" of graphs is not possible. Is there a way that I can dump the output of viewGraph() in a file and run dot

Dear everyone, I want to traverse call graph, but I have some trouble . In my pass MyPass which need to traverse call graph, I firstly added the CallGraph analysis to the pass requirements by *AU.addRequired<CallGraph>();* My pass MyPass then will be added to a pass manager by *manager.add(new MyPass());* and then I want to traverse the call graph such as: CallGraph CG =

This patch allows one to repeat the '-x' option a third time to stop rsync from traversing potentially cyclic bind mounts that are on the same filesystem. For example, the following scenario would cyclically traverse the bind mounts until the OS (Linux in this case) hits a maximum traversal count, thank goodness. Other OSes may traverse the bind mount indefinitely... su cd mkdir

Hey all, I'm working on adding function attribute propagation to function summaries in the ThinLTO index, and have run into some trouble with ensuring bottom-up traversal when finding the SCCs in the call graph. I'm basing my implementation for the GraphTraits for the ModuleSummaryIndex off the GraphTraits<CallGraph *> implementation (

I recall having a similar problem while coding my own special-purpose "opt". My guess: try adding the following lines before your pass is inserted into the PassManager: PassRegistry &Registry = *PassRegistry::getPassRegistry(); initializeIPA(Registry); You might require other library initializations. Have a look at the "opt" source code. On 02/12/13 10:36,

I am using ruby *1.8.4* (2005-12-24). I added this code: #define RARRAY_LEN(a) \ ((RBASIC(a)->flags & RARRAY_EMBED_FLAG) ? \ (long)((RBASIC(a)->flags >> RARRAY_EMBED_LEN_SHIFT) & \ (RARRAY_EMBED_LEN_MASK >> RARRAY_EMBED_LEN_SHIFT)) : \ RARRAY(a)->as.heap.len) #define RARRAY_PTR(a) \ ((RBASIC(a)->flags & RARRAY_EMBED_FLAG) ? \

Hello All, I would like your help to learn how to traverse an LLVM DAG and perform some analysis. I know that llc can be used to view a DAG, but I would like to manipulate them. In particular I'm interested in the instruction selection and the scheduling DAGs. I have read the documentation about writing an analysis pass and I know how to traverse a basic block on a LLVM IR assembly file, but

I am finding some weird behavior in the CallGraph, and am not sure what am I doing wrong. When trying to traverse nodes in the CallGraph I get stuck in nodes representing external functions. Take the following code: ----- #include <stdio.h> int main() { printf( "Hello World!\n" ); } ----- If I try to traverse the CallGraph using the following code: ----- CallGraph CG

I have been running Samba 4 as an AD/DC for a couple of years now with few problems. I provisioned the domain using --dns-backend=BIND9_FLATFILE and the /etc/named.conf includes the samba-tool provision created file /var/lib/samba/private/named.conf, with zone files in /var/lib/samba/private/dns. All that has been working just fine for for 2 or 3 years. Lately, I added a VirtualBox XP guest

Hi all, This question was probably asked million times before, but I wasted few hours and didn't find the solution.. What is the best way to traverse a large array (say size of million) with GetElementPtr The problem with the following code, is that it forces you to create million constant index values: intVars = new AllocaInst(Type::getInt32Ty(ctx), allocaSize, "intVars",

Hi, Can anyone tell me how to traverse Dominator tree in pre-order manner? Regards, Chayan
