I'm writing a JIT for my toy language, and I'm confused by one thing. How do I, with IR Builder, Insert a pointer constant? For the first version of my jit, I really only need LLVM to pass around opaque types and then pass those variables to C functions that return other opaque types. So for instance, I have a Int object that wraps the GNU GMP routines. A want to be able to tell IRBuilder

I'd like to do some simple C# -> LLVM C API bindings for windows. Is there a place I can get pre-built LLVM .dlls for windows?

I'm working on implementing a simple functional language in LLVM. It's statically typed, but I'd like to a have some simple multimethods involved. Does LLVM have some intrinsics for handling something like C++ vtables? Or do I need to implement my own way of handling single-dispatch functions? Thanks, Timothy -- “One of the main causes of the fall of the Roman Empire was

...the generated X86 code doesn't treat the resulting pointer as a constant... for instance, if you use it as a function pointer, the X86 code ends up being an indirect call through a function pointer in a register, rather than a direct call.

I can't seem to get LLVMCreateTargetMachine to work on my box (MBP i7 OS X 10.8). What should the values of triple, cpu and features be? I'm just looking for a way to get this up and going for now, I don't need specific optimizations. No matter what I send the function, I always get nil back. I'm giving it LLVMGetFirstTarget as the target value. Thanks for the help, Timothy

On OSX I thought I'd try to optimize my compiler a bit by switching some of the calling conventions from CCallingConv to FastCC. The compiler ran fine, but when I executed the code, I got "Bad Instruction 4". I'm seeing some other mentions on this mailing list of issues like this on OSX (I'm using 10.8). Is there anything I need to change to enable fastcc with my compiler? I

I'm writing a compiler using LLVM, and suddenly today I started to get this error, when emitting to a .s file. Assertion failed: (I != M+Size && I->FromReg == RegNum && "Invalid RegNum"), function getLLVMRegNum, file MCRegisterInfo.cpp, line 78. I'm emitting using x86_64-apple-darwin. Any thoughts about what could be causing this? LLVM validation does not

I'm in the process of writing a library and giving a talk about writing compilers using LLVM (llvm-c) and Clojure. As part of my talk I'd like to give an example of a program running on CUDA. Are there any papers, tutorials, examples, on writing a custom frontend for NVPTX? For instance, I'm trying to figure out how to get access to "global" variables like blockidx. I know

...Timothy, I'm not sure what you mean by this working for other intrinsics, but in this case, I think you want the intrinsic name llvm.nvvm.read.ptx.sreg.tid.x.

In the creation of dynamic languages we often have to box values together. For instance, take the following expression: IntObj c = sqrt((a*a)+(b*b)); Here, most likely, a bytecode interpreter would execute this as "mul_ints", "add_ints", "sqrt", etc. Inside these primitive functions we would have to unwrap our IntObj types, add the values, allocate a new object and

I'm building this with llvm-c, and accessing these intrinsics via calling the intrinsic as if it were a function. class F_SREG<string OpStr, NVPTXRegClass regclassOut, Intrinsic IntOp> : NVPTXInst<(outs regclassOut:$dst), (ins), OpStr, [(set regclassOut:$dst, (IntOp))]>; def INT_PTX_SREG_TID_X : F_SREG<"mov.u32 \t$dst, %tid.x;",

There seems to be some interest these days in OpenCL. However for some projects, a issue they face to adopting OpenCL is requirements of maintaining two source trees: one for normal C code (for use on systems without OpenCL support or poor OpenCL performance) and another for OpenCL. I am interested in using LLVM to create a OpenCL frontend for multicore CPUs. Now that the spec is out, we have a

Awesome, is the development of this being tracked somewhere? And is there a way I can get involved?

Greetings! As part of a compiler project I am working on, I am interested in porting LLVM to Irix/MIPS. I figure I could start by working with the bytecode to C translation part of LLVM. However, when I run configure, llvm is saying that it does not recognize the host I am working with. Are there any documents about how to port to a new OS/Instruction set? Thanks, Timothy -- "... one of

Maybe I'm not doing something right here, but there is a rather simple bug in the Autoconfig.sh script. It currently checks for the version numbers in aclocal and libtool. However it only accepts a certain value, instead of that version and all newer versions. Is there a reason for this? Or is this a bug?
