Hint, Nudge, Wink: the last patch I sent that hits on the assembler
should make it very easy to add better assembly checking
For example, register checking could be done like this:
if($rtype eq "I" || $rtype eq "N" || $rtype eq "P" || $rtype eq "S") {
# its a register argument
if($args[$_]=~m/^[INPS](\d+)$/) {
my($arg_num)=$1;
if($arg_num > 32) {
# bad register number
} else {
$args[$_]=$arg_num;
}
} else {
# non-register being used!
}
} ...
