Hi Jean-Daniel, My fault, I'm sure, but I don't see the problem yet. Is it possible your version of llvm/Config/AsmPrinters.def has X86 listed twice? - Daniel On Mon, Aug 2, 2010 at 12:43 AM, Jean-Daniel Dupas <devlists at shadowlab.org> wrote: > Hello, > > After I try making a clean build and got the following error: > > llvm[3]: Compiling EDDisassembler.cpp for

Hello, After I try making a clean build and got the following error: llvm[3]: Compiling EDDisassembler.cpp for Release build In file included from /llvm/include/llvm/Target/TargetSelect.h:38, from /llvm/lib/MC/MCDisassembler/EDDisassembler.cpp:37: /llvm/stage1/include/llvm/Config/AsmPrinters.def: In function ‘void LLVMInitializeX86TargetAsmPrinter()’:

Hi, I wrote a compiler that generate IR code and run it on the JIT, and there randomly crashed due to "corrupted size vs. prev_size" depends on the IR code generated from the source code.

IIRC, this error might be due to not linking against the MCJIT library component. Add the appropriate flags to your build config, and also ensure that you call InitializeNativeTargetAsmPrinter() and InitializeNativeTargetAsmParser(). > Also, what's the code quality of MCJIT compared to the old JIT?

Following along from lli code, if you add a call to InitializeNativeTargetAsmPrinter() during setup, it gets a bit farther and crashes rather than issuing that error.

With the following call: llvm::ExecutionEngine* engine; llvm::EngineBuilder builder( module ); builder.setEngineKind( llvm::EngineKind::Either ); // it will use JIT if available builder.setUseMCJIT ( true ); engine = builder.create(); These calls are successful in windows. But when I try in Linux (Ubuntu), the create() function fails with the error message: Target does not support MC emission

Ah, now that makes sense. Guess I was a little over-eager with my bugreport. Thanks! :) However, I am now running into the same Problem as Matt ("Target does not support MC emission!").

Hi Ralf, FYI, old JIT doesn't support AVX at all, no encoding info, etc... The only way to use AVX+JIT is using MCJIT, which contains the correct encoding, but unfortunately the framework isn't good yet as the old one is.
