Note the PPC only happens on powerpc-elf and powerpc-eabi, it does not happen on powerpc-
darwin6.6 or powerpc-aix5.1.

Looks like this is an effect of the SYSV ABI.

This is because g1 is allocated space on the stack as a result of the following
code in expand_function_start. If a function has local variables (including
hidden ones like this one) then it needs a stack frame. Other ABIs can create
leaf functions having local vars without necessarily creating a stack frame.
/* If function gets a static chain arg, store it in the stack frame.
Do this first, so it gets the first stack slot offset. */
if (current_function_needs_context)
{
last_ptr = assign_stack_local (Pmode, GET_MODE_SIZE (Pmode), 0);
