Hi Carlo, rather than declaring individual stack variables int x; int y; int z; and so on, which requires you to pass each one, or a pointer to each one, to your function, declare one stack variable of struct type that holds them all: struct StackObjects { int x; int y; int z; ... }; ... struct StackObjects stack; then pass the address of stack to your

I'm trying to figure out how to feed a blockaddress to a switch condition AND destination (basically emulating an indirectbr via a switch; I know it's not a good approach, I'm just experimenting). Suppose I have the following: SwitchInst *s = SwitchInst::Create(...); BasicBlock *bb = ...; PtrToIntInst k = new PtrToIntInst(BlockAddress::get(bb), <TYPE>, "", s);

I need some advice on "forwarding" arguments to a callee. Suppose I have a function F that is called at the beginning of all other functions in the module. From F I need to access (read) the arguments passed to its immediate caller. Right now I do something like boxing all arguments in the caller inside a struct and passing a pointer to the struct to F, alongside an identifier

...h equivalent to an anonymous struct / const struct reference. (Why not? Because calling conventions differ from platform to platform; often the first few arguments of a function are passed in registers, not on the stack.)

Hi all, I want to run a legacy function-level pass on only parts of the functions of a module (for example, only those functions named with "_built_in_" prefix). How can i do it? I don't want to rewrite the pass itself. best regards, Yabin -------------- next part -------------- An HTML attachment was scrubbed... URL:

I consider my patch not mature enough to be committed. I just wanted to hear what others are saying. I'm not quite sure how to exactly deal with these cascades of selects which induce a cycle via a Phi; I'd like to implement that as well. Also, I'm not sure whether InstructionSimplify.cpp is the proper place for this optimization. -- Roland ----- Original Message ----- > From:
