RE: [arm-gnu] Which version of gdb supports ARMv7 architecture?

Daniel, Mark,

	Thanks for the prompt feedback. Do you know when we're likely to
add the display support?

Thanks.

I think it will disassemble NEON instructions, but it won't usefully
display values in NEON registers.  They overlap the VFPv3 registers; I
believe we only support the VFPv2 registers at the moment, so half of
them are missing.  And we only display those registers as single /
double floating point, not as vectors.

I think we'd need a bit more work to say we supported debugging; not
a huge amount, though.  Additional register names, types, and Mark S.
pointed out that it might be useful to add some custom code for
printing the polynomial data types.

Of course this work would need to go with particular debug sprites,
e.g. the RDI sprite.
