Andy McFadden	98914e9f80	Treat BRK as a 1-byte instruction The 65816 definition makes it a two-byte instruction, like COP. On the 6502 it acted like a two-byte instruction, but in practice very few assemblers treat it that way. Very few humans, for that matter. So it's now treated as a single byte instruction, with the following byte encoded as a data value.	2019-08-02 17:21:50 -07:00

Treat BRK as a 1-byte instruction

The 65816 definition makes it a two-byte instruction, like COP.  On
the 6502 it acted like a two-byte instruction, but in practice very
few assemblers treat it that way.  Very few humans, for that matter.
So it's now treated as a single byte instruction, with the following
byte encoded as a data value.

Add 2014-label-dp

This is primarily to exercise a Merlin 32 failure (issue #37).
However, it also exercises a problem with cc65 (issue #40).
Currently, only 64tass can assemble this project.
