Hello, I’m trying to port a project up to 4.0 and I’m seeing the following error: In file included from /Users/jaredcarlson/Projects/llvm-4.0.0.src/include/llvm/ADT/StringRef.h:13: /Users/jaredcarlson/Projects/llvm-4.0.0.src/include/llvm/ADT/STLExtras.h:139:13: error: no type named 'type' in 'std::__1::result_of<std::__1::pointer_to_unary_function<llvm::DSNode *, llvm::DSNode

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 LLVM folks, As the sequel of my blog posts shared previously: Writing LLVM Pass in 2018 - [Part I](https://medium.com/@mshockwave/writing-llvm-pass-in-2018-part-i-531c700e85eb <https://medium.com/@mshockwave/writing-llvm-pass-in-2018-part-i-531c700e85eb> ) and [Part II](https://medium.com/@mshockwave/writing-llvm-pass-in-2018-part-ii-640f680978ec

Hi list, I am making a simple custom pass that inserts print function calls for each instruction, so that compiled programs print out all llvm instructions on the dynamic path. For example, (conceptually) printf(“%s”, “x = x + 1”); // inserted code x = y + 1; // original code But it seems that there are some conflicts with existing optimization paths. When I compile a program with the custom

You are right. Thanks! I fixed that one as well as some other issues. I built LLVM-8 with Debug + no-rtti. But it now has the following error: Stack dump: 0. Program arguments: clang-8 -cc1 -triple x86_64-unknown-linux-gnu -emit-llvm -disable-free -main-file-name time-1.7.c -mrelocation-model static -mthread-model posix -mdisable-fp-elim -fmath-errno -masm-verbose -mconstructor-aliases

Hi Tim, Thanks for your suggestion! I built LLVM with Debug and tried this with my custom pass. But it has the following error error: unable to load plugin '../../trace-extractor/build/TracePass.so': '../../trace-extractor/build/TracePass.so: undefined symbol: _ZTIN4llvm10ModulePassE’ Originally I used a builtin Clang in the system and it does not produce this issue. When I search

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

Hi, thanks for the answer. Am Sonntag, 11. Juni 2017, 02:16:36 CEST schrieben Sie: > Have you tried building LLVM with assertions enabled?

The problem seems to be the argument iterator. Do you know some way to

Hi, Though there exists lots of researches on parallelizing or scheduling optimization passes, If you open up the time matrices of codegen(llc -time-passes), you'll find that the most time consuming task is actually instruction selection(40~50% of time) instead of optimization passes(10~0%). That's why we're trying to parallelize the (target-independent) instruction selection process

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

Dear developers: When I am doing basicblock pass, I meet a bug: there is an iterator "I" in a basicblock, and it is not pointing to the first instruction in this basicblock. However, "I--;" will fail by an assertion. The basic block ("I" is pointing to the second instruction) in test.ll: bb: ; preds = %bb1 %1 = call i32 (i8*, ...)* @printf(i8* noalias

Hi, I was trying to create a new *Store* instruction and inserting it to LLVM IR (.ll) file. I found the following constructor in LLVM Manual: StoreInst::StoreInst <http://llvm.org/docs/doxygen/html/classllvm_1_1StoreInst.html#aa2a72f9a51b317f5b4ab8695adf59025> (Value <http://llvm.org/docs/doxygen/html/classllvm_1_1Value.html> * Val, Value

The various intrinsic assert/crashes should all be fixed on mainline CVS (they are PR733, which I just fixed). The only ones that I'm wary of are: XPASS: /proj/llvm/build/../llvm/test/Regression/CFrontend/2004-02-20- StaticRedeclare.c.tr FAIL: /proj/llvm/build/../llvm/test/Regression/CFrontend/2005-12-04- DeclarationLineNumbers.c: In the former case, I would guess that the test isn't

Branches have been created. You are free to checkin to cvs head again. I'll send mail once I have the prerelease tar balls up. Please continue to review and revise the documentation. I can fold this into the release later. Thanks, Tanya On Thu, 13 Apr 2006, Tanya Lattner wrote: > > I will be creating the release branch at 1:00pm PDT. Please refrain from > checking in from
