[LLVMdev] Modelling M68k registers?
...;word load and store in ARM? Or maybe I
should treat data and address registers differently since writing to
the 'subregs' of a data reg to not change the upper bits, whereas with
address registers all 32bits are signed extended, as in:
move.l #$12345678, d0
move.w #$fedc, d0 ; d0==$1234fedc
move.l #$12345678, a0
move.w #$fedc, a0 ; a0==$fffffedc
