Hi! In Line 230 of llvm\Support\TypeBuilder.h is support for void*: /// void* is disallowed in LLVM types, but it occurs often enough in C code that /// we special case it. template<> class TypeBuilder<void*, false> : public TypeBuilder<types::i<8>*, false> {}; If would be cool if the same thing can be added fo...

Are you using TypeBuilder (http://llvm.org/viewvc/llvm-project/llvm/branches/release_26/include/llvm/Support/TypeBuilder.h?view=markup, new in 2.6) and IRBuilder, or trying to use the individual type and value classes directly? I recommend the builders when they support what you need. I don't think they'll ever comp...

You need a pointer-to-function type, but FunctionType just gives you a function type. Use PointerType::getUnqual(FunctionType::get(...)). Or TypeBuilder<char (*func)(void*), false>::get(context) from Support/TypeBuilder.h.

Hi all. I would like to declare a function that takes a function pointer as an argument. In C, it would be : void execute(char (*func)(void*), void *param) So, in my compiler, I have : std::vector<const Type *> cbFPtrArgs(1, Type::getInt8PtrTy(C)); FunctionType * cbFPtrTy = FunctionType::get(Type::getInt8Ty(C), cbFPtrArgs, false); Function * func =

For my introductory Compiler Construction class, I have been giving the students a project to write a simple compiler for a toy, single- inheritance object-oriented language. We give them a set of classes implementing an AST for the language and a type checker as well. The students write (1) a scanner and parser to build the AST; (2) a translator from AST to LLVM; and (3) a couple of

Hi, I'm having a play with LLVM to implement a custom language (for my intellectual curiosity only). I'm wondering how, when using IRBuilder, one can can it to emit a recursive type definition? The code for TypeBuilder explicitly states that it doesn't handle recursive types... I'm after being able to emit, programmatically, stuff like the Named Types example in the Language Reference: %mytype = type { %mytype*, i32 } I'd welcome any advice! Yours, James Jackson. -------------- next part ----------...

That and the possibility of differently sized pointers made me hesitate to dive into implementing this. I guess nailing it down to be the platform equivalent of size_t would be sensible here.

Hi, I'm trying to replace function call with call to wrapper(function_name, num_args, ...), where varargs hold args of original call.

I looked through the "intp" thread. I don't really want to start that argument up again, but my immediate thought would be to create a new class of "picked-by-the-target" integer types (equivelents of size_t, intptr_t, etc...), and two new instructions, zcast and scast, which are only valid in the context of casting to / from integer types of unknown sizes. To begin with,

Hello, If this is not the correct list to ask this question on I apologize. I am attempting to generate a llvm.memcpy instruction with an IRBuilder but I cannot find the appropriate way to do this.

Dear all, I am wondering if there is some API to add extern function declaration to bc file. For example, as given below, I want to add the line "extern void foo();" to my bc file with some llvm methods, how can I do this, please? extern void foo(); // the llvm bc code is: declare void @_Z3foov(). How can I add this line to llvm bc using some llvm methods?

I'm looking for an example of how to insert a new function into a module. I have a module pass that needs to create some new functions. Tia. Reed

I tried what you said, now I get: LLVM ERROR: Program used external function 'yipee' which could not be resolved! Stack dump: 0.

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
