> It is a bit confusing. Was coldfire the only target supporting Floating Point registers at the time?
Nope! I don't really know the history here. Internally we discussed
maybe supporting an "m68k.fp" feature, but in the end decided it wasn't
worth the effort, since older versions of gdb would not support this anyway.
> I happened to noticed that we only have coldfire.core in the XML description. Are we lacking a coldfire.fp XML in GDB? Is it only provided by non-GDB stubs?
Yeah, I don't know why gdb doesn't have other XML descriptions for m68k.
In this case the "coldfire.fp" feature is coming from an XML description
that qemu supplies.
