For my introductory Compiler Construction class, I have been giving the students a project to write a simple compiler for a toy, single- inheritance object-oriented language. We give them a set of classes implementing an AST for the language and a type checker as well. The students write (1) a scanner and parser to build the AST; (2) a translator from AST to LLVM; and (3) a couple of

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,

In Unladen Swallow we (intend to) compile each function as we determine it's hot. To "compile" a function means to translate it from CPython bytecode to LLVM IR, optimize the IR using a FunctionPassManager, and JIT the IR to machine code. We'd like to include inlining among our optimizations. Currently the Inliner is a CallGraphSCCPass, which can only be run by the

Not sure, but it seems the page contains a number of out-of-date entries: Pypy => pypy.org (link stale) plus: there is no llvm backend for pypy at the moment (although LLVM backends have been attempted a number of times, all seem to have failed) Unladen Swallow => not being developed since 2011 (http://qinsb.blogspot.com/2011/03/unladen-swallow-retrospective.html) TIA, Andreas The

I want to connect each llvm ir for example: 1. Turn C/C++ language into C_llvmIR assembly language using Clang 2. Turn Fortran language into Fortran_llvmIR assembly language using Dragonegg 3. Turn Python language into Python_llvmIR assembly language using Unladen-Swallow 4. Connect each llvm IR Is this possible? Wonjun, Choi -------------- next part -------------- An HTML attachment was

Hello Duncan, > thanks for your interesting email. Do you understand why PyPy is no longer > using LLVM, and why Unladen Swallow died? Does LLVM need to be improved in > some way? The answers to all these questions are linked: LLVM is not fast enough (for a JIT). Of course this is not the whole story, but it is the LLVM-relevant part. Let's have a look at some random performance

Can someone tell me if syslinux will work on a harddisk ? I have a 4mb flash device that plugs into the IDE connector on the motherboard, and i'm trying to get syslinux to work with it, so I can load a Linux kernel and an initrd. I'm not having any luck with it. Then it dawned on me that the boot loader in syslinux might be expecting a floppy drive rather than an atapi hard disk. Any

Hi, Has anyone had any success with running different PassManagers on llvm::Modules they've already JITed and are executing? In detail: 1) getting the IR, in form of an llvm::Module 2) calling PassManager->run() on the module 3) calling getFunction() and getPointerToFunction() to JIT the module 4) executing the JITed code using the function pointer received in step 3 and then what I

For LLVM users like me,

The only VHDL to LLVM project that I know of is nvc. [0] I haven't tried it personally and from a cursory look through the source it seems like there is a LLVM backend and a "native" backend (not sure what that means). If you're really crazy you might want to see if you could massage GHDL [1] (VHDL GCC frontend) + DragonEgg [2] (LLVM backend for GCC) to get you LLVM IR. I'm

Hi all, First, I just want to say thank you for the excellent LLVM project. I have been playing with LLVM for the first part of this year and have been quite impressed with what I've seen and what is possible. I've been coding for a long time, but haven't had this much fun since I first learned Python. The work you have done has opened the door for a tremendous amount of

Hi, I found the following wiki page in the Unladen Swallow project: http://code.google.com/p/unladen-swallow/wiki/CodeLifecycle This would appear to answer my question. Could someone confirm for me if it's definitely unsafe to attempt to optimise/JIT any Modules while a different thread is currently executing a JITed function which has been generated from them? Or am I just missing

Thanks for the report. The attached patch removes them from the page. OK?

Right now, on X86, creating multiple ExecutionEngines in the same process causes an assertion. If it's supposed to always be a singleton, should there be a way to get the process's ExecutionEngine instance? This would, among other things, allow "lli" to execute bitcode that itself uses the ExecutionEngine.
