Hi, I'm working on a very embedded project where we have no operating system, and there is no window overflow trap handler. I'm really stretched for memory and I'd like to reduce the stack size. I haven't not being able to find anyone else who is looking at reducing the stack usage by google searching, but it seems like there is room to be saved, and I need the extra space.
As I have no window overflow trap handler the space reserved on the stack for saving in and local registers is just wasted memory. Is there any way I can reclaim this space by forcing the compiler to not honour the standard SPARC ABI? Would it be possible to take this one step further and drop the stack space for arguments? We don't have functions with large numbers of arguments, so all arguments should be passed in registers. Although only a single word, the One-word hidden parameter, seems like a waste if none of our code ever uses it. David
