GlobalVariable::copyAttributesFrom sets the target thread local mode to either general dynamic or not thread local rather than copying the thread local mode from the source. Is that intentional or an oversight? Thanks, Keno -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.llvm.org/pip...

Hi! I have a module containing a constant e.g. @input = global %0 zeroinitializer, align 16 when I copy the global into another module I use newGlobal->copyAttributesFrom(global); but the new module now has @input = external global %0, align 16 i.e. the zeroinitializer is missing. how do I set it or copy it from the other global? -Jochen

The initializer doesn't count as an attribute, I guess. if (global->hasInitializer()) newGloba...

Hi everybody, I am trying to clone a function body into an existing declaration. That declaration has the same number of parameters but they differ in type and alignment. Fortunately, it does not care about the type. Unfortunately, CloneFunctionInto() copies the attributes from the old function to the new one unconditionally, overwriting the alignment attribute. Also, the Attribute interface

Hi John, thanks for the pointer. However, I'd rather avoid rolling a custom implementation. After all, it's not like I want to do something drastically different... I had sorted out the problem for 3.2 as well as a previous version of 3.3 trunk, but the API changed about a hundred times. Now as it apparently has stabilized, I moved to a the 3.3 release branch just to find that even

I'm now writing a pass and I wanna ask a question about how to duplicate the function and add duplicated arguments in llvm, for example: func(int a, char *b) -> func(int a, char *b, int a1, char *b1) I'm now stuck at using "getOrInsertFunction" and how to handle "getArgumentList", please share your opinion, thanks a lot! James

Dear all, In the process of trying to add optimization for better layout of global variables, I have run up against a roadblock: I don`t seem to be able to sort the contents of a "SymbolTableListTraits<GlobalVariable>" -- or even swap two elements in that list -- without causing LLVM to crash. I have tried writing a comparator class and then using "llvm::iplist<
