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'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

1. Create an extern global variable of the type being pointed to. Use ExecutionEngine::addGlobalMapping to map that extern global variable to the pointer. Then your IR code can refer to the extern global variable and get the pointer. 2. Convert the pointer to an int. Create an int constant in IR. Then add an inttoptr instruction, and your IR has the pointer constant. Last I checked, though,

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

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

Hi 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. For me, this looks like: %x = call i32 @llvm.nvvm.read.ptx.sreg.tid.x() Pete On Fri, Mar 1, 2013 at 11:51 AM, Timothy Baldridge <tbaldridge at gmail.com> wrote: > I'm building this with llvm-c, and accessing these

The identifier INT_PTX_SREG_TID_X is the name of an instruction as the back-end sees it, and has very little to do with the name you should use in your IR. Your best bet is to look at the include/llvm/IR/IntrinsicsNVVM.td file and see the definitions for each intrinsic. Then, the name mapping is just: int_foo_bar -> llvm.foo.bar() int_ prefix becomes llvm., and all underscores turn into

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

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?

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

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

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;",

I have a C# program that requires the run of a logistic regression.
