Vikram, I have implemented a front-end for a new language that generates LLVM assembly language. I used that approach for three reasons: 1. The API learning curve looked steep. 2. It is easy to read the LLVM assembly source to see if things are correct. 3. But mainly, I wanted to implement my front-end in my new language, so the C/C++ bindings might not be applicable or easy to use. Each

Hello, If this is not the correct list to ask this question on I apologize. I am attempting to generate a llvm.memcpy instruction with an IRBuilder but I cannot find the appropriate way to do this.

Hi! In Line 230 of llvm\Support\TypeBuilder.h is support for void*: /// void* is disallowed in LLVM types, but it occurs often enough in C code that /// we special case it. template<> class TypeBuilder<void*, false> : public TypeBuilder<types::i<8>*, false> {}; If would be cool if the same thing can be added for const void*: template<> class

Hi, I am senior student at Tashkent University of Information Technologies and I am highly interested in programming language design. I want to develop Python front-end for HLVM as a part of LLVM participation in Google Summer of Code project. I am in long love with Python programming language for its simplicity and effectiveness. Last year I noticed ShedSkin Python to C++ translator among SoC

Hi all. I would like to declare a function that takes a function pointer as an argument. In C, it would be : void execute(char (*func)(void*), void *param) So, in my compiler, I have : std::vector<const Type *> cbFPtrArgs(1, Type::getInt8PtrTy(C)); FunctionType * cbFPtrTy = FunctionType::get(Type::getInt8Ty(C), cbFPtrArgs, false); Function * func =

You need a pointer-to-function type, but FunctionType just gives you a function type. Use PointerType::getUnqual(FunctionType::get(...)). Or TypeBuilder<char (*func)(void*), false>::get(context) from Support/TypeBuilder.h.

That and the possibility of differently sized pointers made me hesitate to dive into implementing this. I guess nailing it down to be the platform equivalent of size_t would be sensible here.

Here's how you can do a single file (i.e., an unlinked executable): llvmg++ -c infile.cpp -o - | llc -march=c -o infile.cbe.c Reid might be able to tell you how to do it with a single command using the llvmc tool.

Please create a similar branch for Klee; I've been working on porting that to 2.7 as well.<br /> <br /> Best, Erich Ocean<br /> <br /> On Fri, Mar 5, 2010 at 8:43 PM, John Criswell (criswell@uiuc.edu) wrote:<br /> > <br /> > Dear SAFECoders and LLVMers,<br /> > <br /> > There is some new work on moving DSA to the new LLVM 2.7 API.

Hi, I'm interested in using the "Data Structure Analysis" that is apparently in the "poolalloc" module according to the documentation on alias analysis in LLVM. I have downloaded and built LLVM 2.6 on MinGW but the sources do not seem to include anything related to pool allocation. I don't think MinGW includes svn. Is there an download location where I can get the

Hello. I would like to know if writing a new front-end for a widely-used programming language (in my case, Oberon) is a valid proposal for GSoC. By the way, I'm porting the original Wirth's Oberon compiler and I think that making available a translator for this language with an industrial-quality backend would make it a more interesting choice for many projects. Best regards. Walter

Hi, Slightly off-topic (as it's not directly about using or developing LLVM): http://code.google.com/p/unladen-swallow/wiki/ProjectPlan "Our long-term proposal is to replace CPython's custom virtual machine with a JIT built on top of LLVM, while leaving the rest of the Python runtime relatively intact." Just curious, has anyone here heard more about this project? Regards,

Howdy! I've noticed that requests for help by people like me who are developing front ends are often lost in the noise in the llvm-dev list. Although LLVM is a wonderful and very productive framework, I've found that getting help on my front end has been very difficult, and learning necessary detail about the APIs and the like is often very, very challenging. Perhaps it would be good to

I just checked in an important change to the LLVM Verifier pass, and have compiled a new version of the GCC front-end. The big change is that we now match the LangRef.html much more closely: many operations on pointer operands are illegal. Essentially, the GCC front-end should never generate adds, subtracts, multiplies, divides, rem, or shr/shl instructions that take pointer operands now. In

Hi, I'm having a play with LLVM to implement a custom language (for my intellectual curiosity only). I'm wondering how, when using IRBuilder, one can can it to emit a recursive type definition? The code for TypeBuilder explicitly states that it doesn't handle recursive types... I'm after being able to emit, programmatically, stuff like the Named Types example in the Language
