Hi yes, I'm asking for any advice, I want to implement multithreaded code generator in LLVM. tnx --- On Tue, 10/5/10, Duncan Sands <baldrick at free.fr> wrote: From: Duncan Sands <baldrick at free.fr> Subject: Re: [LLVMdev] Multithreaded code generation To: llvmdev at cs.uiuc.edu Date: Tuesday, October 5, 2010, 10:50 AM Hi Hamed, > I want to use LLVM to automatically

Hi I want to use LLVM to automatically generate multithreaded code for execution on multicore processors. My problem is  code generation for multicores and concurrency primitives. Is there any facilities for code generation? How should I start?  Best Regards. -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hello I want to write a pass which insert a new call to a library function but I don't know how to create a CallInst that calls a function like "pthread_create", can anyone help me with this problem? -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hello, I want to use some code written for program dependence graph iteration, but this code uses hash_map (#include "llvm/ADT/hash_map") which i think remove from llvm, does anyone know how can i use hsah_map or simply replace that?

Hi, In fact I have some theory on instruction level parallelism( i have a partitioning algorithm), then first of all, i want to generate a multithreaded code from LLVM IR (in assembly level) with a given partitioning. My problem is how can i use a thread library(like Pthread) or OS system calls in LLVM IR to create and manage threads? --- On Tue, 10/5/10, Tobias Grosser <grosser at

However, if you limit yourself for the moment to loops that fit into the polyhedral model, you can take

I have a new plan for handling 'unwinds to' in the control flow graph and dominance. Just as a quick recap the problem I encountered is how to deal instructions in a block being used as operands in the unwind dest. Such as this: bb1: unwinds to %cleanup call void @foo() ; might throw, might not %x = add i32 %y, %z call void @foo() ; might throw, might not ret void cleanup:

Hi, As part of an ongoing work to extend the GraphDiff (this models a CFG view), I came across the need to have a common interface for accessing successors/predecessors in various IR units, such that a type such as `typename NodeT::succ_iterator` could be used in templated code. In particular, the need arose for BasicBlocks, MachineBasicBlocks, VPBlockBase and clang::CFGBlock. The least invasive

Hi Dave, It may be possible to do this with the current API, but what I was looking for is a common API for existing block types. For example there is no succ_begin for Machine BasicBlock. I'm looking to make the CFGSuccessors and CFGPredecessors classes in CFGDiff.h templated, and this needs a common API for all types instantiations. Does this clarify your question or did I misunderstand

Hi, this is a bit of a newbie question: I am trying to discover, given a block with a conditional and its successors, which condition (T/F) each successor applies to. There's almost identical code in CFGPrinter.cpp, but where it gets called in GraphWriter.h, the child_iterator type is a pretty hairy thing, so I still don't quite understand how to get one from a BasicBlock in my own

Hi list, I'm trying to create an asterisk 1.8 rpm with SRTP. I found mention of a libsrtp rpm, <http://qutecom.ipex.cz/RPMS/srtp-1.4.4-1.i386.rpm > in these instructions, <http://www.voip-info.org/wiki/view/Asterisk+SRTP> but it is unreachable (by me, anyway). The libSRTP source is here, <http://srtp.sourceforge.net/download.html>. Has this already been packaged for

Hi, all : I have a thought of writing the script to implement the LDAP mail notice recently. That's to say , after creating the new account and his passwd , then how to send an E-mail to notice him? By the way , I used the LDAP tool called 389 LDAP or openldap recently . Could someone give me some suggestions ? Thanks in advance..... -------------- next part -------------- An

Newbie Question .. (sorry if its redundant/silly) .. As I've started to develop Stacker, I had assumed that simply adding BasicBlocks to a function in sequence would imply that there is an implicit unconditional branch from the end of one basic block to the start of the next block. Based on the assertion checks that I get when I tried this, I assume that it is required to place a terminating

Hi Scott, Sorry for the late reply, I was out of office during the holidays. 1. A def node can reach either a use node, or another def node. In the highlighted phi node (p3224), the def (d3225) reaches another def (1598) in statement (s1597), that’s why it’s needed. 2. The reason why the def of R11 in s1578 is not connected directly to the use in s1725 is that there may be an intervening

Hi all, LLVM optimization pass gives an error "Terminator found in the middle of a basic block!" since basic block IR may have multiple "ret" instructions. It seems LLVM does not accept multiple return in a basic block by default. Is there a specific optimization or pass that I can enable to remove unreachable codes in basic blocks?
