...To JIT compile C++ code, we do basically as follows: 1. call Driver::BuildCompilation(), which returns a clang Command to execute 2. create a CompilerInvocation using the arguments from the Command 3. create a CompilerInstance around the CompilerInvocation 4. use the CompilerInstance to execute an EmitLLVMOnlyAction 5. retrieve the resulting Module from the action and add it to the JIT But to compile C++ requires only a single clang command. When you add CUDA to the equation, you add several other steps. If you use the clang front end to compile, clang does the following: 1. compiles the driver source cod...

Hi, I'm writing to both lists as I'm not sure what the cause of this issue is. I use code like this to compile C source into LLVM IR as suggested on the Clang mailing list previously. class CompileBitcodeAction : public clang::EmitLLVMOnlyAction { protected: Module*& dstModule; public: inline CompileBitcodeAction(Module*& dstModule, LLVMContext* const context = NULL) : clang::EmitLLVMOnlyAction(context), dstModule(dstModule) {} protected: virtual inline void EndSourceFileAction() { clang::Em...

...developers to adhere strictly to coding guidelines, I wrote the attached program called "alias-detector". The program's intent is to utilize the BasicAliasAnalysis to get a list of aliases for each pointer in a certain program code. First it initializes clang as frontend, executes the EmitLLVMOnlyAction, and then processes the produced Module with the following three passes: 1. BasicAliasAnalysis -- The basic alias analysis 2. AliasTrackerPass -- BasicBlockPass that creates an AliasSet for each pointer in the analyzed code (line 261 and line 94 respectively) 3. AliasDetectorPass -- BasicBlockPa...

I have made a bit of progress... When compiling CUDA source code in memory, the Compilation instance returned by Driver::BuildCompilation() contains two clang Commands: one for the host and one for the CUDA device. I can execute both commands using EmitLLVMOnlyActions. I add the Module from the host compilation to my JIT as usual, but... what to do with the Module from the device compilation? If I just add it to the JIT, I get an error message like this: Added modules have incompatible data layouts: e-i64:64-i128:128-v16:16-v32:32-n16:32:64 (module) vs...

I tried what you said, now I get: LLVM ERROR: Program used external function 'yipee' which could not be resolved! Stack dump: 0. Running pass 'X86 Machine Code Emitter' on function '@main' did not even get as far as a breakpoint. Óscar Fuentes wrote: > > gafferuk <gafferuk at gmail.com> writes: > >> Im confused.

Declare the function: int yipee(int); int main() { int dd = yipee(1); return 0; } If that still crashes, put a breakpoint on `yipee' and see if the execution gets there, if the argument is
