Hi list, I have several questions about LLVM pass. 1) Is building a custom LLVM pass out-of-source not recommended? The official document only contains instructions about in-source build (http://llvm.org/docs/WritingAnLLVMPass.html <http://llvm.org/docs/WritingAnLLVMPass.html>). 2) opt (ver >= 4) with custom pass libraries does not work as before. When I have a simple custom LLVM pass

Hi, don't know if this is the right list. Please post a better place, otherwise. I'm currently writing a LLVM ModulePass and ran into strange segfaults or endless loops within LLVM. My main question is, if this is a programming error or API misuse from me or a LLVM bug? Here is some minimal code, that triggers the bug: ---------------- class DebugPass : public ModulePass { public:

Hi all, I was able to create a pass following [1]. Now goal is amend the pass and try to dump the call graph. I think I have properly amended the source extending my pass from CallGraphSCCPass but unfortunately every time I run it, it crashes. I tried with llvm-6 and llvm-7. I notice that if I change EP_EarlyAsPossible to anything else it does not crash but I don't see the expected string

Hello everyone, I have written simple LLVM passes, but I cannot able to write a MachineFunctionPass pass. I am following the steps form the following link but it is not working: http://www.gabriel.urdhr.fr/2014/09/26/adding-a-llvm-pass/ Please share the sample MachineFunctionPass code or steps to follow to write MachineFunctionPass. Thanks, Bala -- Thanks, Bala IIITA Allahabad --------------

Hello, I have written a pass that works nicely if I use it with the opt tool, as proposed by the "Writing an LLVM Pass" tutorial. Now I want to execute this pass directly when clang is executed. I use the technique described here: http://homes.cs.washington.edu/~asampson/blog/clangpass.html. The pass is loaded and executed, when I run clang with the right command line. But clang

Hello, I have created a ModulePass, that now needs LoopInfo information. The ModulePass registration is taken from [1]. I use clang to directly invoke it (This is also a hard requirement, because I need the fancy output of clang warnings/remarks). The problem is, that the dependency to the LoopInfoWrapperPass does not seem to work. The error is: --- snip --- clang-4.0:

Hi all, I’m currently writing an LLVM function pass and I want to know how can I test it? Currently, I try to compile some crypto library and check if the test suite are working but I don’t think this is very efficient. Does anyone has a leads?

Hi all, *TL;DR:* I have a target TMS9900CodeGen but cmake is looking for LLVMTMS9900 or LLVMTMS9900CodeGen which I don't have, and cmake dies. But the MSP430 target doesn't have that either, and cmake is happy with it. What am I missing? *The premise:* I may be making a huge mistake, but I'm trying to develop an LLVM backend. I'm writing up some notes while I do so, and I hope

First you should learn how to write a pass and then a MachineFunctionPass. >From LLVM website, you can refer to http://llvm.org/docs/WritingAnLLVMPass.html And for outside pass, you can refer to http://adriansampson.net/blog/llvm.html It's a great article. And the author put the source code on Github <https://github.com/sampsyo/llvm-pass-skeleton>. 2016-03-01 14:36 GMT+08:00

I was suprised to find that some bitcode I'm generating isn't getting optimized. Here, I'm doing the equivalent of "myarray[5]++" (on an "extern int *myarray"), repeated three times: @myarray = external global i32* define void @update_array() #0 { %1 = load i32** @myarray, align 8 %2 = getelementptr inbounds i32* %1, i64 5 %3 = load

Hi, Is it possible to generate pass (shared object) from Cmake? I tried to use add_llvm_library() however it produces only static libs. Thanks, Mariusz.

Hi- Danny Burkes here from Lingr (http://www.lingr.com). We''re evaluating bdrb and so far, so good. It''s deployed in staging now and seems to be working fine. I have a couple of questions that I couldn''t find references to in the archive, so here it goes- 1. Is there any way to do a "graceful" stop of bdrb? What I mean is, I want to stop bdrb,
