The uncategorized data scanner isn't supposed to create strings or
".fill" directives that straddle labels, long comments, notes,
visualizations, or ORG directives. The test for crossing an ORG
directive is incomplete, and doesn't correctly handle no-op ORGs
(where the new address is the same as the old address).
The code generator doesn't output ORGs that are hidden inside other
things, so we're not generating bad code, but it looks funny on
screen and may cause problems later on. The 2004-numeric-types test
has the basic .align/.fill/.bulk directive tests, and now has an
extended set of tests for uncategorized data region splitting.
Sometimes there's a bunch of junk in the binary that isn't used for
anything. Often it's there to make things line up at the start of
a page boundary.
This adds a ".junk" directive that tells the disassembler that it
can safely disregard the contents of a region. If the region ends
on a power-of-two boundary, an alignment value can be specified.
The assembly source generators will output an alignment directive
when possible, a .fill directive when appropriate, and a .dense
directive when all else fails. Because we're required to regenerate
the original data file, it's not always possible to avoid generating
a hex dump.
There's no easy way to make non-zero-bank 65816 code work, so I'm
punting and just generating a whole-file hex dump for those. This
renders tests 2007 and 2009 useless, so I'm hesitant to claim that
ACME support is fully functional.
