28% This must be the last file on the link-line, allocating global registers
29% from the top.

31% Register $254 is the stack-pointer.
32sp GREG
33
34% Register $253 is frame-pointer.  It's not supposed to be used in most
35% functions.
36fp GREG
37
38% $252 is the static chain register; nested functions receive the
39% context of the surrounding function through a pointer passed in this
40% register.
41static_chain GREG
42struct_value_reg GREG
43
44% These registers are used to pass state at an exceptional return (C++).

72% Provide last part of _init and _fini.

74% The return address is stored in the topmost stored register in the
75% register-stack.  We ignore the current value in rJ.  It is probably
76% garbage because each fragment of _init and _fini may have their own idea
77% of the current stack frame, if they're cut out from a "real" function
78% like in gcc/crtstuff.c.
