Bcc:

Happy days.. That wasn't obvious to me. I'll check out the details later.

Thanks.

The PowerPC (look in config/rs6000) has no stack.

All GCC needs is that you define a register to be the stack pointer
(STACK_POINTER_REGNUM) and this register doesn't have to be a base register
(see "Addressing modes" in the GCC Internals manual). Even a pushm1 pattern
(see "Standard Pattern Names for Generation") is not necessary if you are
happy with the code that GCC itself comes up with.
