Unless I'm missing something, indeed addGlobalMapping should not work with MCJIT. MCJIT does not consult EEState.getGlobalAddressMap when resolving symbols. Instead it uses RTDyldMemoryManager::getSymbolAddress which checks with DynamicLibrary::SearchForAddressOfSymbol, so Andy's suggestion of DynamicLibrary::addSymbol is better as it should work with both JIT and MCJIT. Another options

Hello, I am using updateGlobalMapping to inform the JIT engine the address of some C helpers. Due to the nature of the analysis pass, there can be several calls to updateGlobalMapping with the same GlobalValue key and the same (or sometimes different) address. My problem is when the reverse mapping is enabled, the following fragment: // If we are using the reverse mapping, add it too. if

This is what I was trying to do when I ran into the HowToUseJIT problem. I've made a first attempt at adding locking to the JIT. Unfortunately, since I do not really understand the structure of LLVM, I could have very easily screwed something up. I touched two classes, the JIT and the ExecutionEngine. I need some help from someone who is more familiar with the code to make sure that I

I'm working on building a target for llvm that's the intermediate language of another compiler, so that the other compiler can benifit from llvm's optimization passes. I essentially made a copy of the mips backend, and then started changing the output to match the intermediate language of the compiler. Most of the output can be overriden, but I haven't figured out how to change

Hi, Is it possible to run Objective-C code in lli? lli does not seem to want to load Foundation.framework. Please see below. Thanks, Eric Brunstad #import <Foundation/Foundation.h> int main(int argc, char *argv[]) { NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init]; NSLog(@"test!"); [pool drain]; return EXIT_SUCCESS; } cmu-351714:llvm-2.5 ericbrunstad$

Thanks for your quick response Joerg. We have a very small test case where there is global array and its address space attribute specified like in the following code const int __attribute__((address_space(256))) fangle[13] = {2341, 4681, 7022, 9362, 11703, 1403,16384, 18725, 21065, 23406, 25746, 28087, 30427}; I need to put its initializer in another memory because it has a different

It is definitely possible, but we're not there yet. LLI would have to know about objective-c metadata to register it properly with the runtime. This is important for things like classes etc. This isn't

Hi, What would be an estimate for the amount of work required to implement this? Where would I get started if I were to implement it? My goal is to run Objective-C programs in the interpreter so I can provide an application-sandbox by disallowing the invocation of certain C-functions and also by disallowing the invocation of certain Objective-C methods.

On OS X (10.6.2) running on an Intel Core 2 duo with LLVM 2.7 pulled about a month ago from CVS and built in debug mode: Using the JIT system with exception handling, I am having issues with type infos. "Finally" code (llvm.eh.selector intrinsic call with 0) works fine (correct landing pads found), as does this call with one type info. My type infos are each 64 bit array GlobalVariables

Hi Allan, Thanks for the fix! So is this a bug in LLVM? Can you reduce that to a small test case and file a bug?

Well, I think there is a bug in vmkit for always trying to do pointer arithmetic using i32 instead of the target's pointer size, which is what my patch addressed. As for whether there is a bug in LLVM, I'm not sure. I've played around with it some more, and it looks like zext expressions get constant folded before reaching LowerConstant. The only way I've triggered the
