e5ac21f0f9 Second attempt at implementation of the BBXn instructions for Rockwell 65c02 chips. 
Reliable technical documentation for how these instructions are decoded is a
little thin on the ground online, so some of this implementation is still
speculative.

7f650e787d Fix the bugs the test suite found 
- .require now tracks absolute paths of loaded files
 - stricter checking of .incbin arguments
 - fix charmap reset directive

 - Allow opcode names as labels, with warning

cc9acf3ce4 Bugfix: Let Collapse Pass reverse collapses

label past the zero-page boundary.

23700276a6 Introduce wide-mode override opcodes. 
This solves the --no-collapse problem by letting you force
Absolute mode on an instruction by instruction bases, which is
usually going to be what you want anyway.

4891849e4a Pass control command line options. 
It turns out that --enable-collapse is fundamentally misguided. We'll
need a better solution for that. --no-branch-extension looks pretty good.

7e503df96f Bugfix: .include wasn't blocking later .requires 
When crossing directories, this will still be wrong, but that's a
larger fix for later.

9323067e91 Improve .incbin to let its arguments be arbitrary expressions 
This introduces a new IR node for mutable-during-assembly ranges.
In the common case, where offset and range are hardcoded or missing,
it continues with the older, more efficient behavior.

86e58efce8 Merge catseye's incbin-range enhancement. 
Needed a little work to merge cleanly, but no real surprises.

This isn't a complete solution yet, but it will work for the
basic case. It should allow expressions and gracefully handle
non-hardcoded cases (while still efficiently handling hardcoded
ones).

cf0df92fb1 Wrap up the new file/dir handling. 
An .outfile directive lets sources suggest default filenames.

Also, .include, .require, .incbin, and .charmapbin are relative
to their _source file_ as opposed the _directory you called Ophis
from_, like it really should have always been.

17f68399ef Allow support for multiple input files. 
To account for this change, output files are now prefixed with the
-o option, and if none is specified, it defaults to 'ophis.bin'.

14a37ca879 Massive code modernization spree. 
Full PEP8 compliance. Also, booleans have been inserted where
they make sense (introduced in 2.3!) and I haven't knowingly
added anything that will break 2.3 compatibility.

At this point the code really doesn't look like it was written
ten years ago. Hooray!
 2012-06-02 00:04:15 -07:00
Michael Martin
f83379287f Don't destroy the OptParser. 
As long as we're not gratuitously breaking compatibility, this
cleanup isn't available in 2.3 and it's not like ophis runs long
enough for this to be an issue anyway.

d955fe00a1 Switch to "new-style" classes, because come on. 
Ophis was originally written for Python 2.1, and it kind of shows.
Python 2.3 introduced booleans and optparse, so there's no reason
to not use new-style classes.
