Hi all, I downloaded LLVM to play with today and found that the BrainF example compiler fails with an assertion error like so: examples$ ./BrainF -jit /tmp/test.bf BrainF: Instructions.cpp:242: void llvm::CallInst::init(llvm::Value*, llvm::Value* const*, unsigned int): Assertion `(NumParams == FTy->getNumParams() || (FTy->isVarArg() && NumParams > FT...

...use llvm as a backend for compiling executable programs; here's my understanding of the state of affairs so far: Kaleidoscope demonstrates how to generate code in memory, and run it in memory using JIT for interactive use (which will be handy in due course for providing an interactive option); BrainF demonstrates how to output intermediate code; but it is preferable to take it all the way to CPU specific assembly. CPU specific assembly is as far as llvm goes, at that point one hands over to the GNU assembler and linker to generate an executable program. Generating assembly output is demonstrate...

...i, i already successfully compiled & installled LLVM 3.1 on Windows (with CMake & Visual Studio 2008). next, i am trying to understand how to create a standalone LLVM project, and compile that on Windows (also using CMake & Visual Studio 2008). to start, i picked up the "examples\BrainF" project, renamed it to "examples\BrainF2" (and i still put BrainF2 under the same examples\ directory) next, inside BrainF2, i run on Windows console: c:\llvm-3.1\examples\BrainF2\> cmake -G "Visual Studio 9 2008" but then cmake complains error like "unknown CMa...

I don't think so about arm-wince. What's wrong with running LLVM on ARM? It's supposed to support ARM as a target, and since it's written in C it should theoretically compile for ARM. CMake

The only changes that I'm not 100% happy with are the ShadowStackCollector changes. The code will currently assert if the BasePtr passed in to the ShadowStackCollector is a constant as the GEP will be a constant. If we want to make th...

...say "compiler_rt now supports ARM targets". What else is needed? Keep in mind that I do not need (or want) Clang or any of the optimizers: I just want to generate small sequences of machine code in-memory (on the heap, I assume) and execute them. By the way, LLVM comes with 66 projects (BrainF, bugpoint, Kaleidoscope, llc, etc.) and it's not obvious which one(s) I actually need to accomplish this "simple" use of LLVM.
