All these bugs are for x86; I don't know about sparc/alpha.
--- argument marshalling for ccall is fundamentally flawed, since
- it moves the C stack pointer %esp as it pushes each argument.
- Alas, the register allocator spills relative to %esp and
- assumes that it doesn't move. Result: if the marshalling code
- for a ccall involves any spills, the resulting code will
- probably be wrong.
-
- The Right Way to fix this is to copy stuff onto the stack
- without moving %esp, then adjust it immediately prior to the
- call insn and un-adjust it immediately following it.

-- nofib/spectral/cvh_unboxing exposes some kind of spilling bug
(I think), since there are many references to registers %M229
