I'm porting a modula-2 compiler to the sparc and I'm having some
difficulties with the Stack pointer, seems that the second I touch it
(let's say sub %sp,4,%sp) to enlarge my frame, every register is shifted
%i0 -> %i1 etc..., looks like I went through a window trap with a restore
but without save (get this results from adb while stepping over sub).
Does anyone have any idea ? By the way, how's adb handling instruction
pipelining ? And can I assume that save %sp,XX,%sp saves locals and ins
into %sp..%sp on a window overflow ?
Thank's a lot.
