Hello, I'm having a little problem with passes that use LoopInfo. Their statistics aren't the same when I execute the same pass multiple times in the same program. After some investigation, I've found out that LoopInfo is the root of the problem. I wrote a little pass that counts the loop headers (number of basic blocks for which LoopInfo.isLoopHeader(BB) is true). I've picked

Check out the bug report at http://llvm.org/bugs/show_bug.cgi?id=13144 and try adding KEEP_SYMBOLS := 1 to tools/opt/Makefile like the OP suggests.

Dear LLVMers, My name is Raphael Ernani, and I am doing my MsC at the Federal University of Minas Gerais, Brazil. I have been using LLVM for a while, and I would like to participate in this year's Summer of Code. One particular idea, in your "open projects" page caught my eye, and I decided to write a proposal about it. The line that I liked in the page was "Create an LLVM

Hi, The LLVM has a good test suite. I recommend it. You can test your pass with single-source programs and multi-source programs. You can also configure the test-suite to run your test with external benchmarks within the LLVM test suite. You can also run some programs after you use your pass, to verify if your pass don't affect the behavior of the compiled program. You can do it with the

Dear LLVMers, we have released a tool that uses LLVM to insert OpenACC or OpenMP 4.0 directives in programs. You can use the tool online here: http://cuda.dcc.ufmg.br/dawn/. Our tool, dawn-cc, analyzes the LLVM IR to infer the sizes of memory chunks, and to find dependences within loops. After that, we use debug information to translate the low-level information back into annotations that we

Dear LLVMers, we, at UFMG, have been building a large collection of compilable benchmarks. Today, we have one million C files, mined from open-source repositories, that compile into LLVM bytecodes (and from there to object files). To ensure compilation, we perform type inference on the C programs. Type inference lets us replace missing dependencies. The benchmarks are available at:

Yes, we have a very extensive report about it. Take a look

Hi Florian, we though about using UIUC, like in LLVM. Do you guys know if that could be a problem, given that we are mining the functions from github? > Have you thought about integrating the benchmarks as external tests into LLVM’s test-suite? That would make it very easy to play around with. We did not think about it actually. But we would be happy to do it, if the community accepts

Dear LLVMers, concerning a few points of the discussion about code-size reduction (Minutes available at https://docs.google.com/document/d/1kDsbFDtkWLceR-Y63ez04CBfvhbDN8RxWV3xXwaNUC0/edit?usp=sharing): > Do we need different levels like -Os1, -Os2, -Os3? Together with a colleague, Anderson Faustino, we spend some time finding optimization sequences that are good for code-size reduction.

Dear LLVMers, I wrote a new proposal, to improve the static array bounds checking in SAFEcode, as follows: Improving static array bounds checking in SAFEcode ================================================== Objective --------- the main objective of this project is to improve the static array bounds checking engine used in SAFECode. It was written after the open project at

Dear LLVMers, I have a class X that represents a set of Value* in a specific way. That class is stored in two files: X.cpp and X.h The class X works perfectly in a pass that I already have. However, I need to use that class in some other passes, but I don't want to have a copy of X.cpp and X.h in every pass folder. I've tried to do the following: - put X.h in the folder

Greetings LLVMers, I would like to add the licensed part of AnghaBench (http://cuda.dcc.ufmg.br/angha/) as an External Test in the LLVM test-suite. We have 128,411 files with their original licenses. (http://www.dcc.ufmg.br/~fernando/coisas/c_files_with_licenses.tar.gz) Each file is a single function, that compiles as is---no dependencies are needed. For instance, the commands below work for each

Dear Mehdi, I've changed your example a little bit: float saxpy(float a, float *x, float *y, int n) { int j = 0; for (int i = 0; i < n; ++i) { y[j] = a*x[i] + y[I]; // Change 'I' into 'j'? ++j; } } I get this code below, once I replace 'I' with 'j'. We are copying n positions of both arrays, 'x' and 'y': float saxpy(float a,

Dear llvmers, I decided to write my own scripts to compile the SPEC programs, and they work fine, except with 403.gcc. Basically, I take the file 403.gcc.linked.rbc from the ...\Output folder that the LLVM test suite produces. Then I use this linked.rbc file to generate an executable file via the following commands: llc 403.gcc.linked.rbc -o 403.gcc.linked.s clang 403.gcc.linked.s -o
