I have my own llvm pass which requires mem2reg. It worked fine with opt. However, I was trying to make it work with clang as I needed it to run some spec cpu benchmarks. Is there any way that I can mention mem2reg (PromotePass) pass as a pre-requisite in my own pass's implementation?

I have used the following command for my pass (without -mem2reg): clang -Xclang -load -Xclang MYPASS.so -c ../../tests/test1.c For mem2reg, I tried the following: clang -mllvm -mem2reg -Xclang -load -Xclang MYPASS.so -c ../../tests/test1.c On Mon, Mar 21, 2016 at 9:26 PM, Mehdi Amini <mehdi.amini at apple.com> wrote: > >> On Mar 21, 2016, at 6:23 PM, Syed Rafiul Hussain

Hi, I was trying to pass llvm option -mem2reg to clang using -mllvm and I found the following error: clang (LLVM option parsing): Unknown command line argument '-mem2reg'. Try: 'clang (LLVM option parsing) -help' clang (LLVM option parsing): Did you mean '-debug'? I would appreciate if anyone could help me. -- Syed Rafiul Hussain

I have added -debug-pass=Structure, and found the following: ModulePass Manager X Analysis Unnamed pass: implement Pass::getPassName() FunctionPass Manager Module Verifier Bitcode Writer Pass Arguments: -x -y -z FunctionPass Manager X Analysis Y Construction Z Construction Even for getAnalysis<Y>(*F) and getAnalysis<Z>(&F), all the passes X,

Hi, I am using llvm-3.8 for my project. Following is my getAnalysisUsage() method: virtual void getAnalysisUsage(AnalysisUsage &AU) const override { AU.setPreservesAll(); AU.addRequired<X>(); AU.addRequired<Y>(); AU.addRequired<Z>(); } Now, if I call getAnalysis<X>(*F), instead of invoking just the X pass, all the passes, i.e., X, Y and Z are being

Unless mem2reg does something other than my understanding of it, I can't see why any pass would "require" that... It is not guaranteed to do anything to any particular piece of code, so relying on it seems very unreliable, I would think. -- Mats On 22 March 2016 at 04:32, Kevin Hu via llvm-dev <llvm-dev at lists.llvm.org> wrote: > Hi, > > > Is there any way that

Thank you all for your reply. if(a>10) b=10; else if (a<10) b = 5; Here is the IR of the if-elseif: 56 %0 = load i32, i32* %a, align 4 57 %cmp = icmp sgt i32 %0, 10 58 br i1 %cmp, label %if.then, label %if.else 60 if.then: ; preds = %entry 61 store i32 10, i32* %b, align 4 62 br label %if.end.4 63 64 if.else:

Sorry, I should ask the following: finds all the instructions of a function where a particular variable is defined? Lets consider the following code snippet: 1. void foo(){ 2. int a, b; 3. if(a > 10) 4. b = 10; 5. if(a<10) 6. b = 5; 7. cout << b; 8. } I would like to know the instructions where variable b can be be defined, i.e, in this case, the instructions 4 and 6. On Wed,

Thanks for the fast response John.

Hi, I am wondering if there is anything like def-use chain which finds all the instructions of a function where a particular value is defined? Thanks. -- Rafi

Hi, I'm trying to get the pool allocator and safe code building against llvm trunk. I've run into a build error, and I see that in the past another user was told just not to build the pool allocator for use with safecode [1]. However, I really want the pool allocator transforms, so I just wanted to check why the suggestion was not to use it. Has it been superseded in some way by something

Hello, I am Abhinav Tripathi, B.Tech 3rd Year student from IIT Indore, India. I was looking on the projects ideas page of llvm and saw that I could also propose to work on the SAFECode Open projects. As I found no mailing list on their site, I am sending this message here. Please redirect me to some other list, if required. . I found most of the projects quite alluring as I have been working on a

I’ve been debugging SAFECode source code files, and line 170 in ArrayBoundCheckLocal.cpp has been causing the following compilation error: In file included from /Users/peterfinn/Desktop/llvm_trunk_2/projects/safecode/lib/ArrayBoundChecks/ArrayBoundCheckLocal.cpp:18: In file included from

Dear Community, The ponyc<https://github.com/CausalityLtd/ponyc/tree/llvm37> (llvm37 branch) project is facing an issue on Windows: When optimizations are turned on (llvm 3.7.0-final and more specifically<https://github.com/CausalityLtd/ponyc/blob/llvm37/src/libponyc/codegen/genopt.cc>, opt-level 3, BBVectorize, LoopVectorize, SLPVectorize, RerollLoops, LoadCombine + a custom heap

Since we are only a week away from branching for 3.7.0, this new breakage in the stage2 bootstrap of llvm/clang/compiler-rt/clang-tools-extra should get triaged. At r241513, a three stage bootstrap with comparision of stage2/stage3 files completed fine. However at r241594 we now have the new regression reported in https://llvm.org/bugs/show_bug.cgi?id=24054... Assertion failed: (Val &&

I hope this is the correct avenue to contact the poolalloc developers. I'm trying to use an alias analysis from the poolalloc repository and can't get it to compile with the latest LLVM. CMake is now required for LLVM, I'm pretty sure at least, but poolalloc does not seem to use it correctly. The README in the project refers to the old Makefiles. I corrected a minor CMake error and a

Hi all, Can anyone give me advice about an appropriate way for extracting number of functions from module recursively (starting from entry point). Actually it may be more than one entry point so all dependent functions and global values must be extracted. I've tried llvm-extract tool but it can't do work recursively. Maybe it would be good to write some Call Graph pass or something. Any

This got me into thinking. Indeed the problem is related to Windows exceptions, so I am not sure whether the bug reported<https://llvm.org/bugs/show_bug.cgi?id=24374> is actually fixed. Compiling Pony code (helloworld) that includes no exceptions does work fine (with optimizations). As soon as exceptions on windows come into play, writing the object file dies with the mentioned error in

Dear All, I'm having some problems using a function pass from a Module pass. My code is as follows: DominatorTree & domTree; ... Function &F = *I; // I is an interator from using Module::begin() ... domTree = getAnalysis<DominatorTree>(F); When I compile this code, I get the following error: /home/vadve/criswell/src/llvm22/include/llvm/Pass.h: In member function
