FIXME: cagney/2003-02-28:
|
|
|
|
|
|
|
|
Unfortunatly, thanks to some legacy architectures, this doesn't
|
|
|
|
hold. A register's cooked (nee virtual) and raw size can differ
|
|
|
|
(see MIPS). Such architectures should be using different register
|
|
|
|
numbers for the different sized views of identical registers.
|
|
|
|
|
|
|
|
Anyway, the up-shot is that, until that mess is fixed, core code
|
|
|
|
can end up being very confused - should the RAW or VIRTUAL size be
|
|
|
|
used? As a rule of thumb, use REGISTER_VIRTUAL_SIZE in cooked
|
|
|
|
code, but with the comment:
|
|
|
|
|
|
|
|
OK: REGISTER_VIRTUAL_SIZE
|
|
|
|
|
