a quick look in .../gnu/usr.bin/gas/opcode/m68k.h reveals that in the
instruction descriptions:
[descriptions deleted...]
then replace your assembler with the hacked on, and viola, you've got
FP instructions for which you don't have a cprocessor...
Thank you for answering my question before I ask it ;-) (I submitted Q
about changing CpID after you submitted this but before I received, I
suppose)
It shouldn't be that hard to get the emulator do a quick check of
#define'd number against the CpID field of the CP instructions --
in fact, you need to do it anyway, so you don't try to interpret
'random' coprocessor instructions as FP ones...
Yes, I'll disable CpID check only for debugging purpose.
I wish only if CpID were dynamically changeable in gas, though.
