similar to: [LLVMdev] objc runtime

Hi, sorry, if I post to the unrelated list. I wish to use code::blocks with the llvm compilers on Windows to use Objective-C 2.0. There are several runtimes with differences in API, how do clang-llvm, llvm-gcc know the type of runtime? I wish to use Apple objc4, is it possible? -- best regards Ariel -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hi again, I had tried to follow David's suggestion to take a step back and look into codegen instead of hacking on RuntimeDyld but then I quickly realized that I don't understand what exactly needs to be done to fully register Objective-C runtime. I decided to iterate on JIT code again and somehow I found that I can hook into SectionMemory by subclassing it and working with its

Hi Stanislav, Sorry -- I am not much help here. I would like to get ObjC runtime support for the JIT, but have not had time to look in to it closely. When I last tested the idea (a couple of years ago now) we used selector registration and objc_readClassPair to get basic test cases working as you have, but ran into (possibly similar) failures on non-trivial test cases. I think the interpretation

And also, the hook to load/unload image is installed in objc-os.m using dyld_register_image_state_change_handler() function.

Thanks for the info! Yes, the problem is certainly that the JITed code isn't registering its classes, but even after digging through all the runtime code I can't find anything that seems suitable for doing this.. The nearest function I could find was _objc_init_image, but that seems to be for win32! I assume that the way it works must be that clang creates some static data structures

Dear community, I'm using gnustep runtime -fobjc-runtime=gnustep with gnustep-libobjc2 (https://github.com/gnustep/libobjc2) and Cocotron/Chameleon. For following source file #import <Foundation/Foundation.h> #import <UIKit/UIKit.h> int main(void) {         NSString *str = [NSString stringWithCString:"TEST"];

Chris rewrote the original LLVM bytecode into it's present bitcode form. The newer code is much smaller than the previous form. That would be my guess for why he chose to call it bitcode. Of course, he can say for himself. :-) -bw On Sep 29, 2010, at 5:15 AM, Ariel Feinerman wrote: > Anyone, > > can you say what was the reason to rename bytecode? I am still interesting in >

Anyone, can you say what was the reason to rename bytecode?

The Objective-C runtime provides public APIs for doing all of this. They’re

Hi all, > I actually looked into this recently. It is possible, but takes some non-trivial effort right now: You have to hook into the JIT memory allocator, parse the objective C metadata sections in the object file, then call the objective C runtime to register any newly added classes, protocols and selectors. > I can't release my code as-is: I built it against a hacked up copy of the

Hi list, As long as I know English the word "bit" is a "small pice", . Why in set of documentation ir is "bytecode", in other set or llvm source is "bitecode"? What is the right? Different people call the same thing such differently. -- best regards Ariel -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hi Kevin I am just pointing out that is a good place to look at how metadata is parsed and it supports parsing metadata from pre-linked object file which is important to JIT. My code pretty much replicate most of the functions in MachODump in C++ and hope it can much more reusable than the c parser. The biggest missing part is the resilience to bad metadata due to the fact we currently don't

We have a similar problem in Mesa's radeonsi driver. It would be great if command-line options could somehow be tied to an llvm::Context, for example. There is an even worse problem when *different versions* of LLVM are loaded into the same process. This is basically guaranteed to lead to crashes because of symbol clashes. I wonder if C++11 inline namespaces could be used for proper
