When I registered for dev conference, there was a field asking what I was particularly interested in learning. I didn't fill it out then , but it occurs to me now that I'd really enjoy a tutorial on how to develop a new back end. I spent some time recently reviewing existing material (documentation and code) and not making a lot of progress. Indeed, under some time pressure, I'm

hello, i want to rewrite clang using c instead of c++,what's your advice and what should i do first,and i want to know where's the source codes of the files which will be read into the buffer to compiler? thank you! -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hi Eli, Thanks for the link! I'm able to compile a standalone pass outside of the source tree, and I'm obviously ably to compile analysis groups inside the source tree. However, the problem comes when I try to do what the tutorial suggests to create an analysis group outside of the source tree. My understanding is that building out of tree requires different methods to register the

Hi! I'm trying to learn LLVM and I want to compile the Kaleidoscope compiler. according to: http://llvm.org/docs/tutorial/LangImpl3.html I'm compiling it with: clang++ -g -O3 test.cpp `llvm-config --cppflags --ldflags --libs core` -o toy and it indeed works. The problem is that when using eclipse it forces me to divide the compilation into two steps: g++ -O0 -g3 -Wall -c

I have been toying around with the LLVM tutorial code and I am trying to deduce what I can from it as a basis for a compiler frontend for a simple language of my own devising (once I understand what I am doing I will probably attempt mapping a more complex language target). I am having some difficulties however understanding how certain things work and I was hoping perhaps someone could help me

i don't understand the source code : static StringMapEntryBase *getTombstoneVal() { return (StringMapEntryBase*)-1; } at "include\llvm\adt\stingmaph" at line 116. "(StringMapEntryBase*)-1" is it the cast or something other? why there is a * after class StringMapEntryBase? thank you ~~ -------------- next part -------------- An HTML attachment was scrubbed...

Hi, I am quite new to LLVM. I just compiled LLVM and clang on Ubuntu11.10 then followed the tutorial http://llvm.org/docs/DebuggingJITedCode.html clang -cc1 -O0 -g -emit-llvm showdebug.c where showdebug.c contains: #include<stdio.h> int main() { printf("hello\n"); return 0; } But I got Fatal error: 'stdio.h' file not found. However, clang showdebug.c has no

Dear Zhang, Compiler ends up invoking cc1 (the backend) anyways. So if you would like to invoke it by hand, the only thing to know is the right combination of options. Try to use the compiler verbose option "-v". It will show you how exactly clang invokes the backend: > clang -v -c showdebug.c clang version 3.2 (trunk 156703) Target: x86_64-unknown-linux-gnu Thread model: posix

Hello all, I'm trying to follow the guide http://llvm.org/docs/WritingAnLLVMPass.html to build an some passes and analysis groups out of tree. However, I'm having some trouble with crashes when I try to follow the guide. The first section provides a very useful example of what the whole .cpp file should look like for the HelloWorld pass. Obviously it's a bit more complex to write the

Hi there, I've been working through the tutorial on using LLVM to implement a small language (http://llvm.org/docs/tutorial/index.html), and I noticed that the code in the tutorial is a bit out of sync with LLVM 3.5. I managed to get the code working, and it appears to even be working correctly. I'd like to help correct the tutorial so that other people can also benefit from the pain

Hi, I'm a grad student working on a C++11 project and I have no compiler background. I apologize for asking basic questions here. Currently I'm looking for ways to optimize my code and as a starting point I wanted to experiment with loop unrolling and further I might consider function in-lining . I have been introduced to JIT compiler of LLVM and the possible application of it in my

Hi all, I am new to LLVM and have been working through the Kaleidoscope tutorial. Everything is working fine so far except for local externs (as opposed to things like the math functions, which are working). Note that I have seen this bug with the reference code listing, as well as my own code. link to code: https://llvm.org/docs/tutorial/LangImpl05.html#full-code-listing [c34n10 kaleidoscope]

Is it possible to write LLVM IR but not using C++? I'm exceedingly terrible at C++. I was thinking, isn't it possible to write the IR using Java? I effectively have emit some sort of binary op codes to be passed into llvm right? The same thing for if I wanted to integrate a GC? Could the interfacing be done in any other language? -------------- next part -------------- An HTML

Hi, I am a complete newbie to LLVM. I have an ANTLR parser, that outputs an AST. I want to comvert this AST to a LLVM IR, Can someone point me some relevant documentation/examples/ etc. on how to go about doing this?

I don't think it's the same problem as you described. By printing I meant calling printf function and passing my global variable as one of the arguments. My code: Instruction* InstructionVisitor::incrementGlobalKey(Instruction* I) { IRBuilder<> Builder(I->getContext()); Builder.SetInsertPoint(I->getNextNode()); GlobalVariable* key =

I don't know if the toy program in chapter 4 of the tutorial implementing Kaleidoscope in llvm with C++ is part of your regression suite, but with the version of llvm I installed last weekend, it does not compile: hendrik at lovesong:~/dv/llvm/tut$ g++ -g toy.cpp `llvm-config --cppflags --ldflags --libs core jit native` -O3 -o toy toy.cpp: In member function ‘virtual llvm::Value*

Hi Everyone, I'm quite new to LLVM and I want to update value of global variable in LLVM IR. I created new global variable in ModulePass: bool runOnModule(llvm::Module &M) { IRBuilder<> Builder(M.getContext()); Instruction *I = &*inst_begin(M.getFunction("main")); Builder.SetInsertPoint(I); M.getOrInsertGlobal("globalKey",

Hello there! I'm an absolute newb at LLVM,and I was hoping someone could answer a few of my questions. I'm currently working on a game engine. As part of it's design, I need a virtual machine for scripts. Is LLVM suited for this at all? Such as registering external functions that can be called from the scripts? And if this did work, it wouldn't really matter what language the
