similar to: [LLVMdev] llvm interpreter for embedded system

Hi chris, I am a novice in compilers and stuff.I want to write an interpreter for AST but I haven't found any links to how to begin :( .Can u give a few pointers to where I can get some material on interpreter basics etc? TIA. Darthrader -- View this message in context: http://www.nabble.com/llvm-interpreter-for-embedded-system-t308478.html#a2737316 Sent from the LLVM - Dev forum at

Hi, what would be needed to make a C/C++ interpreter using the LLVM libraries. We have in our project (http://root.cern.ch) a C/C++ interpreter (http://root.cern.ch/twiki/bin/view/ROOT/CINT), but it has some limitations (the biggest being maintenance). I see there is a libLLVMInterpreter that can interpret the LLVM IR. Could this be used to interpret, or a starting point, to an real

Hello everyone, I'm trying to run a LLVM-Bytecode-file in the interpreter (lli --force-interpreter), but i'm getting the following error-message: LLVM ERROR: Tried to execute an unknown external function: i8* (i32)* malloc My program is calling malloc. If I omit --force-interpreter everything runs as expected. Compiling to Assembler also works without problems. I have compiled LLVM with

It may yet be too early to get a definite answer about this, but I'm wondering what the status of the formerly patented bytecode interpreter in freetype will be in RHEL/Centos 6 and possibly future updates to RHEL/Centos 5. The patent on the technology has apparently now expired. http://freetype.sourceforge.net/patents.html and

To ease portability headaches, I'd like to support several virtual "components" in llvm-config. Possibilities include: all: Include all LLVM libraries. backend: Include either a working native backend or cbackend. engine: Include a working subclass of ExecutionEngine, either the JIT or interpreter. You could, for example, get a typical set of JIT-related libs using:

I am asking this question to see if it is possible or desirable to build a compilation/runtime system for C/C++ that can support the following: 1. allow bc to call native (in dynamically loaded *.so) 2. allow native to call bc (through JIT or interpreter) 3. can compile/interpret C/C++ sources _BASED_ on type info in precompiled bc Motivation: The class files produced by the java compiler

I'm facing a situation where I have generated IR that only needs to be executed once. I've noticed for simple IR it's faster to run the interpreter on it, but for complex IR it's much better to JIT compile and execute it. I'm seeking suggestions for a good heuristic to decide which approach to take for any given IR. I'm leaning in favor of deciding based on the

Hello everyone, I am a novice with KLEE under LLVM. I am trying to build a KLEE project (on a new LLVM environment) and I have the following problem: echo Testing... Testing... echo There should be no assertion fails! There should be no assertion fails! klee -taint=direct taint_direct.o KLEE: output directory = "klee-out-8" klee: error: Cannot find linker input

The only thing that comes to me off the top of my head is to look at the various LLVM tools and applications and see if there are common sets of libraries used by the tools. Ideally we'd want to "llvm-config --libs {toolname}" for each tool where {toolname} is replaced by the virtual component corresponding to the tool. That might be overkill, but if there are multiple tools that

Folks, Having problems getting started with SJava and request help. I get this error when running .JavaInit() (within RGui 1.5.1, on Windows 2000): Error in .JavaInit() : Couldn't start Java Virtual Machine: Cannot find the Omegahat interface manager class. Check you classpath! (Before you right back saying read the emails, please read further - in short, been there, done that)

Dear All (and happy new 2007 year) As a toy hobby project of mine (unrelated to my work [on GCC]), -I'm dreaming of building an open-source Web CGI application capable of generating other CGIs- I would like to (portably) store an LLVM module in bytecode format inside a MySQL table row (probably inside a BLOB = mysql binary large object = big array of bytes). AFAIK, this could easiy be done

So I thought I'd write this down, in case anyone has useful input to it or wants to read up on the decisions later. Currnetly swfdec compiles actions from a flash file into JSScript objects and executes them using the standard Spidermonkey API. While this allows all the niceties that are available with SpiderMonkey (most important: a whole debugging framework with stack inspection etc - see

Hi, I am lead developer of a project that is using LLVM to implement an ahead-of-time compiled functional language. We use llc -tailcallopt to ensure that functions that end in a tail call are compiled to a tail call at the machine level, because we have a number of cases in our interpreter where functions with different function signatures call one another in deeply nested recursive calls. We

Hi, The klee library directory is determined at compile time and cannot be changed afterwards. Have a look at tools/klee/main.cpp to see how it is computed. I usually use Klee without any install step, right from the build directory. This has never given me the error you see.

I am a novice user of "R" and I'm learning with R version 2.8.1, using WinEdt_1.8.1, under Widows Vista Home Version. ## The test function below, from a vector input, returns vector values: # and it contains an "ifelse"statement TEST<- function(x) { low<- -x^2 up<- x^4 ifelse(x>=0,up,low ) } u<- seq(-1,1,0.5) TEST(u)

It seems that there are a few camps here: * The scp power users - this camp believes that scp supporting backtick notation is fine and that running arbitrary commands is a perfectly fine thing to do. * The restricted shell users - this camp believes that scp supporting backtick may not be the best, and there are various restricted shells which can prevent this. Power users may belong to this

It seems llvm interpreter only supports a limited number of external functions. fmod, in particular is not supported. any reason why it is not supported ?
