Hi, I am running Asterisk on Fedora Core 3. I am trying to use DDD to debug Asterisk. However, when I attach the debugger to the Asterisk Process, the Asterisk CLI promt hangs. Does not give any output, and Asterisk stops processing calls... What could be wrong and what is the best way to debug Asterisk...? Appreciate pointers.. Thx a lot, J --------------------------------- Do you

I have completed work merging PARSEC into the LLVM test suite infrastructure? The patch is available at [http://zion.cs.uiuc.edu/~simmon12/parsec.patch]. If there are no objections, would someone please commit this patch to test-suite? Best regards, --Patrick

I figure (hopefully correctly) that I can iterate over all pool descriptors in a program by iterating over all users of poolinit and looking at the first argument. However, once I have a pool descriptor, I need to get its corresponding DSNode in the function in which it is complete (or in the global graph if it is a global). How do I do this? Thanks, --Patrick

I read this before posting; however, that article says that the first operand to this instruction must be a pointer type. The type I have is [16 x i8*], not [16 x i8*]*. --Patrick Óscar Fuentes wrote: > The following message is a courtesy copy of an article > that has been posted to gmane.comp.compilers.llvm.devel as well. > > Patrick Simmons <simmon12 at illinois.edu>

Okay, are C standard library functions typically external in a fully linked LLVM bytecode file? --Patrick Andrew Lenharth wrote: > If the function is external, then DSA won't create a graph for it. > > Andrew > > On Mon, Jul 13, 2009 at 4:54 PM, Patrick Alexander > Simmons<simmon12 at cs.uiuc.edu> wrote: > >> I'm noticing that DSA graphs are not

I'm noticing that DSA graphs are not created for library functions like "puts". The bytecode file runs with lli, so I think I did my linking okay. Is this normal, or does it mean I'm somehow not giving the algorithm the complete program information it needs? Thanks, --Patrick

I'm iterating over all LoadInst and StoreInst-type Instructions in a Function, and getNodeForValue() is sometimes returning NULL. Why is this happening? Shouldn't every load from or store to memory correspond to some DSNode? --Patrick

Would someone please merge this for me? --Patrick On 08/05/10 13:43, Patrick Alexander Simmons wrote: > I have completed work merging PARSEC into the LLVM test suite > infrastructure?

I've been attempting to write my pass (which depends on DSA and pool allocation) against the SVN trunk of LLVM and the llvm-poolalloc project. However, I was thinking it might be better to use the latest stable releases of these codebases. I know that this is the 2.5 branch for LLVM, but are there any stable releases of pool allocation? If so, would there be any disadvantage to my

Has anyone tried using the Eclipse CDT plugin (or another C++ IDE) to develop code in LLVM? I'm specifically interested in getting code completion to work. --Patrick

Hi, I'm trying to run the tests in llvm-suite, but I've run into trouble. First, I had the llvm-suite checkout in a directory alongside the llvm compiler checkout, but, when I ran "make" from llvm-suite, it complained about there not being a Makefile two levels above it, so I moved llvm-suite into the "test" subdirectory inside the llvm compiler checkout. I ran

If the function is external, then DSA won't create a graph for it.

Thanks for all your help so far. My problem is that what I have are the pool descriptors, which I by traversing the uses of poolinit and accessing the first argument of each call. I need to find the DSNode (in the original function) to which this pool descriptor corresponds. The rub is that this pool descriptor of course does not exist except in the clone. If I call getFuncInfo(), I get a

When I run this code from an R-script: ddd = 360 + round ( atan2(-u,-v) / d2r ) print(class(ddd)) print(ddd) ifelse ( ddd>360, ddd-360, ddd ) print(ddd) I get this output: [1] "numeric" [1] 461 213 238 249 251 [1] 461 213 238 249 251 Why does ifelse not change the 461 to 101? I recreated the vector ddd and ran the same ifelse code

Not if the pointer is null or the pointer

Depending on the value of dsa_pass_to_use, either EquivBUDataStructures or EQTDDataStructures is used. In the case that the top-down DSA is used, information is pushed down to nodes in callees. However, if bottom-up DSA is used, information has only been merged upwards and the nodes are not necessarily equivalent. Harmen Andrew Lenharth wrote: > On Tue, Mar 16, 2010 at 3:46 PM, Patrick

Hello all, Summary & Context: ------------------------------- I am starting to write a front-end for some domain specific programming languages. Code generation seems to be working fine. However, I am having trouble generating debug info, to be used by gdb. The problem: -------------------- I generate a foo.ll file, that is later compiled into an executable foo. The foo.ll file I

I am using gdb to debug a c++ library I made for R using Rcpp. However, when I step through the code it seems to go all over the place, and some of the variables have been optimized out so I can't see their values. How can I compile without optimization? Also, is there any neat way to run R with gdb through emacs? Thanks.
