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

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

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? Thanks Timothy -- “One of the main causes of the fall of the Roman Empire was that–lacking zero–they had no way to indicate successful termination of their C programs.” (Robert Firth) -------------- next part -------------- An HTML attachment was scrubbed...

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, I am just starting a new project. I found that the above script rejects Autoconf versions later than 2.59, whereas it ought to accept them, imho. I had to edit the scrip to be able to use it with Autoconf 2.61. Also, aclocal gave the following warning: /usr/share/aclocal/oaf.m4:4: warning: underquoted definition of AM_PATH_OAF /usr/share/aclocal/oaf.m4:4: run info '(automake)Extending

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

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

I'm trying to follow docs/Projects.html to use llvm in a project of my own. If I just copy the sample directory, running configure in the new one works fine: ~/programming/llvm-1.9/projects $ cp -a sample/ zhe ~/programming/llvm-1.9/projects $ cd zhe/ ~/programming/llvm-1.9/projects/zhe $ ./configure configure: creating ./config.status config.status: creating Makefile.common config.status:

Reid, Thanks for the help. I am trying out the fixes you checked into CVS. I seem to be getting some errors running AutoRegen.sh. I am a bit inexperienced with autoconf and m4. The errors I'm getting are below. Do you know what the problem is? I am using machines running FC3. The autoconf version is 2.59, the aclocal version is 1.9.2, and the m4 version is 1.4.1.

Hi, I am attempting to set up a new frontend project based on the sample project (I'm following the instructions at http://llvm.org/docs/Projects.html). In doing so, I hit a problem with AutoRegen.sh which I worked around, and hit a problem with configure that I don't know how to work around. Below is what happens when I attempt to autoconf and configure the sample project that ships

Hello all, I am a beginner of LLVM and want to add a new Target for LLVM. I follow the document (http://llvm.org/docs/WritingAnLLVMBackend.html) to modify autotools/configure.ac. However when I type ./AutoRegen.sh There is an error that "Your autoconf was not detected as being 2.60" I download the source of autoconf 2.60 and install it. And there is the other error that "Your

Try using the --with-llvmsrc and --with-llvmobj options to explicitly set the locations of your LLVM source tree and object tree, respectively. I faintly recall seeing this error and seem to recall using these options to work around it. -- John T. ________________________________________ From: llvmdev-bounces at cs.uiuc.edu [llvmdev-bounces at cs.uiuc.edu] On Behalf Of Lane Schwartz [dowobeha at

Hi Ryan, The output from autoconf doesn't look familiar (but then, does it ever?). Note that it thinks that AC_CONFIG_MAKEFILE isn't defined which is likely if you didn't get the LLVM_SRC_ROOT correct. Here's the only things I can think of: 1. You also need to cvs update llvm/autoconf/m4 to get the new definition of LLVM_CONFIG_PROJECT. 2. You typed in the LLVM source root
