[hatari-devel] FPU disassembly fault

[Douglas Little <doug694@xxxxxxxxxxxxxx>]

I noticed a fault in disassembly today.

Here's the assembly input code I was testing:

fmove.l fp7,d0

fsub.l d0,fp7

And here is what is actually disassembling (and executing!). Note the fmove operand order...

$0354a6 : f200 6380                            fmove.l   d0,fp7

$0354aa : f200 43a8                            fsub.l    d0,fp7

At first I thought it was the assembler, but the opcode encoding is correct, and disassembly is incorrect. It does seem to execute the correct instruction though.
