Hey all, I'm attempting to rewrite something that the AVR backend used to support (through an extremely dirty hack that was reverted before the upstreaming of the target). The removal of the hack can be seen on GitHub https://github.com/avr-llvm/llvm/pull/226/files On the AVR architecture, the stack pointer is not in a standard register, but rather it is a special register which can only

*** Problem The documentation for function "getSize" in both MCRegisterClass and TargetRegisterClass states: /// getSize - Return the size of the register in bytes, which is also the size /// of a stack slot allocated to hold a spilled copy of this register. The problem is that these two values are not always the same. For example, Hexagon has predicate registers that are 8

>It should be possible to get llvm to produce very good code for the Z80... Yes, I was thinking that too. These techniques didn't exist back then, so I'm really looking forward to the point where the first regular C sources can be compiled and see the magic happening in action live :) ------------------------------------------------------------------------ *From:* Bruce Hoult
