[hatari-devel] Small patch to support debugging Line-F exceptions

[Thorsten Otto <admin@xxxxxxxxxxx>]

Hi,

Attached is a small patch to enable hatari to also enter debugger on Line-F exceptions.

There is also a small bug in disassembling the instructions (using the UAE disassembler):

0102F3DC F23C 5623 4058 0000 0000 0000 fmul.d ##9.600000e+01,fp4

(note the duplicate '##' for the constant)
