...control by LLVM. In the demo page, I got : declare i8* @llvm.eh.exception() nounwind But, when a try to emit the code by llvm engine, the name is generate with the sufix .132 ( llvm.eh.exception.132 ) and the Function::getIntrinsicID abort the program. It was so : Intrinsic::getDeclaration(llvm_module,Intrinsic::memset,&Tys,1); Now, it's running with this calling : return cast<Function> llvm_module->getOrInsertFunction(std::string("llvm.eh.exception"), Intrinsic::getType(Intrinsic::eh_exception, &Tys,1)) ); Is...

For LLDB I'm writing a dumb module pass that removes all global variables, by running the following code: bool erased = true; while (erased) { erased = false; for (Module::global_iterator gi = llvm_module.global_begin(), ge = llvm_module.global_end(); gi != ge; ++gi) { GlobalVariable *global_var = dyn_cast<GlobalVariable>(gi); if (global_var->use_empty()) { log->Printf("Did remove %s"...

Hi, When I try to use va_start(ptr), I got the following problem : Type *Tys = PointerType::get(IntegerType::get(8), 0); return Intrinsic::getDeclaration(llvm_module,Intrinsic::vastart,&Tys,1); ............... The Name generated is "llvm.va_start.p0i8", so, it's not found, abending the process. and Len = 18 In intrinsics.gen : if (Len == 13 && !memcmp(Name, "llvm.va_start", 13)) return Intrinsic::vastart; Thanks, Manoel...
