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.

Work around Merlin 32 instruction parsing bug

The 2014-label-dp test now passes.  Prior regression tests are
unaffected.

Also, renamed an IGenerator interface to more accurately reflect
its role.
