similar to: [LLVMdev] Early inlining in LLVM?

Duncan: I am only superficially familiar with LLVM structure. What I am trying to find out is if functions that have a single invocation are still found in the code during the compilation. In Open64 and other compilers, there is an early inlining pass that inlines all procedures that have a single invocation site. The reasoning is that if there is a single call to a procedure, then there is not

Summary: We need to find a reviewer for our implementation of Ball-Laurus path profiling. It is well known that path profiling generates more precise information about a program's behaviour than edge profiling. We are conducting a research project with the goal of developing a methodology to make feedback-directed optimization (FDO) more sound. We are developing combined profiles that enable

Problem solved. I was building llvm in a separate llvm-build directory. I built it within the llvm-src directory (which kept all the llvm .so and my pass' .so in the llvm-src/Release+Asserts/lib directory) to solve the problem. Can anyone tell me what's the difference between writing a pass as a "struct" (as in the tutorial) and as a "class" (as most developers do)?

Thanks for the reply. For the source code: int main() { int a = 0; int *p; p = &a; call_arnamoy(p); int *p1; p1 = p; return 1; } The bit code: %retval = alloca i32, align 4 %a = alloca i32, align 4 %p = alloca i32*, align 8 %p1 = alloca i32*, align 8 store i32 0, i32* %retval store i32 0, i32* %a, align 4 store i32* %a, i32** %p, align 8 %0 = load i32** %p, align 8 %call = call i32

Hey, folk. I am trying to get many figures by using the function "xyplot" in the library "lattice". I tried to using the loop to finish it quickly. But I cannot open the saved file after I run the program. But if I use the function "plot" to get other simply figures, it can work. So I want to ask how I can get the saved figures by using "xyplot". The

Hello; I wanted to insert two new terminator instructions in LLVM IR. I modified the necessary files (as mentioned in the tutorial in LLVM site and some more to meet the new structure of LLVM, (e.g no Lexer.l now, we have LLLexer.cpp. Again in the tutorial, files like LLVMBitCodes.h, include/llvm-c/core.h that need to be modified are not mentioned) But I am getting the error while building

Hello; I was planning to add a new instruction to the LLVM IR (and later to MIPS backend) for TLS(Thread level speculation) support. For this I tried to follow the steps described in http://llvm.org/docs/ExtendingLLVM dot html#instruction. But I could not find any llvm/lib/AsmParser/Lexer.l and llvm/lib/AsmParser/llvmAsmParser.y file in both the svn repository and the source code downloaded

I think I understood the problem you're trying to solve. I didn't, however, understand the problems you are having (maybe you're not running mem2reg?). I do have a little piece of code that I think does (more or less) what you want. Take a look at it, try understanding it, and see if it helps you out. You might have to change it a bit since you're replacing uses after an

Hi all; I have been trying to use the llvm::ConstantArray::get(llvm::LLVMContext&, llvm::StringRef, bool) function but seems it has been deprecated. ProfileDependence.cpp:68:73: error: no matching function for call to ‘llvm::ConstantArray::get(llvm::LLVMContext&, llvm::StringRef, bool)’ ProfileDependence.cpp:68:73: note: candidate is:

We are running multiple SAMBA servers but they all access the same printers, so I would like to copy the config files (as there are about 100 printers) from the main server to the others so that al the attached drivers and comments and such are intact. Any ideas on this one? BTW Our servers are running Solaris8, Linux (red hat 7.2), etc... -- -Broderick Wood- Analyst, Systems Support Group

Hello; I wrote this simple loop pass to collect the number of instructions in each loop of the program. The code is as follows- #define DEBUG_TYPE "loopinst" #include "llvm/Pass.h" #include "llvm/Analysis/LoopPass.h" #include "llvm/Support/raw_ostream.h" #include "llvm/ADT/Statistic.h" #include "llvm/Instructions.h" #include

Hi; I wrote an LLVM transformation pass and I put my code inside the llvm-src/lib/Transforms/my-pass directory. I want to know what is the correct method for compiling it and building my plugin for the pass. After reading the http://llvm.org/docs/WritingAnLLVMPass.html page, I felt that I have to keep my pass inside the above said directory. But when I run make from inside my-pass directory

Hello all; So here is my goal: *** If there is a Call instruction to myFunction(int * val), I need to identify all the instructions that uses val in the IR and replace the uses with a newly created pointer. I will also be changing the argument of myFunction to the new pointer. int * val = malloc/calloc; ... myFunction(val); .... *val = 45; becomes== int * val = malloc/calloc; int * val1 =

Dear R Community, I am happy to introduce the next release of the *dclone* package (see R Journal, 2(2): 29-37, 2010) which now includes a suite of functions for parallel computations: - see functions parJagsModel, parUpdate, parCodaSamples using 'snow' type clusters; and the - jags.parfit function that can be used with 'snow' type clusters or multiple cores. - iterative model

Dear R Community, I am happy to introduce the latest version 1.3-0 of the 'dclone' R package. The package provides low level functions for implementing maximum likelihood estimating procedures for complex models using data cloning and Bayesian Markov chain Monte Carlo methods with support for JAGS, WinBUGS and OpenBUGS. Data cloning is a global optimization approach and a variant of

Hi; I was wondering how can I get the name of the bitcode file on which I am running the pass. I am making my pass as a loadable module. And if I run my pass like this - opt -S -loops -load /home/arnie/llvm-clang/llvm/Release+Asserts/lib/XYZ.so -xyz <b.bc> b1.bc I want to get b.bc in the pass.
