LLVM does not have explicit methods to build the CFG because it is

Hi, Is there any API within llvm that provides methods to access the CFG and do some manipulations on the CFG. Thanks, Rohith. -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.llvm.org/pipermail/llvm-dev/attachments/20100317/5536c443/attachment.html>

Hi, I've written a pass that basically does some code transformations to enable parallel execution. After the transformation llvm runs BitCode Writer pass , which is aborting with Unreachable Executed error. What does this error generally mean?. Any pointers on how to go about debugging this. Thanks, Rohith. -------------- next part -------------- An HTML attachment was scrubbed...

Run the verifier pass after your pass. The bitcode readers and writers assume that the IR is well-formed, which yours may not be.

Hi, I'm trying to create a GEP (inbounds) instruction . I was looking at the createinboundsGEP method . I didnt get the inputiterator part. My question how do i create a GEP instruction and what do i pass for the input iterator arguments. Thanks, Rohith. -------------- next part -------------- An HTML attachment was scrubbed... URL:

Thanks. The problem i'm facing is i want to get the address of the first element of an array and i have also tried using the createInBoundsGEP which takes the base pointer and the index value and a name. When i try passing '0' as the index im running into problems. Thanks, Rohith. On Sun, Apr 25, 2010 at 10:27 PM, Eli Friedman <eli.friedman at gmail.com>wrote: > On Sun, Apr

Hi all, I have to create a return instruction in a function. The function is of type -- void * func (void *) . So i have to create a return instruction for the function that should return a void pointer. But actually the function will not return anything useful . it will be something like -- return void * null. The problem i am facing is to create a return instruction the Create function

Hi, Is there a way in which i can move an instruction from one basicblock to another?.(without giving the instruction a new name). I'm actually trying to move the body of a given loop into a new function. If i would be able to move basicblocks's that would be ideal. So is there a way to move a basicblock into a function?. Thanks, Rohith. -------------- next part -------------- An HTML

Hi , I'm working on a project in which i need to find out all free variables in a loop. I need to find all variables used inside a loop and that are not declared(allocated) in the loop. I'm confused about what symbol tables to use to get hold of such variables. Thanks, Rohith. -------------- next part -------------- An HTML attachment was scrubbed... URL:

When you say "variables," are you talking about LLVM virtual

Hi All, I'm trying to use the inbuilt AliasAnalysis function for one of my projects. Im trying to find out if a pair of load and store alias each other. It would be helpful if somebody could point out the right way to do this. Example : %13 = load i32* %12, align 4 store i32 30, i32* %4, align 4 So in the above example i'm trying to find out if

John, Thanks, this would work. But we are interested in obtaining the instruction that defines/allocates the value of interest. Once we obtain that we can use LoopInfo pass to check whether the basic block containing that definition instruction belongs to the loop in question. Is there a method that returns the defining instruction? Thanks, Adarsh On Mon, Apr 19, 2010 at 10:05 AM, John Criswell

Hi, I have the value of a getelementptr instruction. How can i find how many bytes it is accessing from the base address. I need this to call the alias method.

Hi, My pass compiles fine with Gmake,but when i run it with 'opt' it was initially breaking with the following error message : "Error opening '../../../Release/lib/ReusePass.so': ../../../Release/lib/ReusePass.so: undefined symbol: _ZNK4llvm4Pass5printERSoPKNS_6ModuleE -load request ignored. opt: Unknown command line argument '-ReusePass'." Then i

Dear R users, I would like to employ count data as covariates while fitting a logistic regression model. My question is: do I violate any assumption of the logistic (and, more in general, of the generalized linear) models by employing count, non-negative integer variables as independent variables? I found a lot of references in the literature regarding hot to use count data as outcome,

I''m developing an rails app. The SVN repository resides on a (Win 2k) server on my company''s local intranet. The repository is accessed via http (Apache + mod_dav_svn). From this machine, it is not a problem to get out onto the Internet. However, coming in from the Internet is not possible (at least, not without a VPN connection). Given this, is it possible to use

Hello all, Forgive me if this is a really stupid question. How do you render partials in a layout? It''s probably way easier than i believe it to be. thanks! -- Posted via http://www.ruby-forum.com/.

In looking over the bugs list, it seems to me that most of them are things we can no longer do anything about, because they are on old versions or broken systems or were features or .... There are now so many they obscure the bugs needing attention. I am about the remove the following. If anyone thinks they are still relevant, could you please send a follow-up to R-bugs with details under 1.2.0
