Created the "all ops" tests for W65C02. Filled in enough of the
necessary infrastructure to be able to create the project and
disassemble the file, though we're not yet handling the instructions
correctly.
Long operands, such as strings and bulk data, can span multiple lines.
SourceGen wraps them at 64 characters, which is fine for assembly
output but occasionally annoying on screen: if the operand column is
wide enough to show the entire value, the comment column is pushed
pretty far to the right.
This change makes the width configurable, as 32/48/64 characters,
with a pop-up in app settings.
The assemblers are all wired to 64 characters, though we could make
this configurable as well with an assembler-specific setting.
Some things have moved around a bit in app settings. The Asm Config
tab now comes last. Having it sandwiched in the middle of tabs that
altered the on-screen display didn't make much sense. The Display
Format is now explicitly for opcodes and operands, and is split into
two columns. The left column is managed by the "quick set" feature,
the right column is independent.
If you double-click on the opcode of an instruction whose operand is
an address or equate, the selection jumps to that address. This
feature is now available in the Navigate menu, with the keyboard
shortcut Ctrl+J.
While testing the feature I noticed that the keyboard focus wasn't
following the selection, so if you jumped to an address and then
used the up/down arrows, you jumped back to the previous location.
(This was true when double-clicking an opcode to jump; it was just
less noticeable since the next action was likely mouse-based.) This
has been fixed by updating the ListView item focus when we jump to a
new location.

The regression tests were written with the assumption that all cross
assemblers would support 6502, 65C02, and 65816 code. There are a
few that support 65816 partially (e.g. ACME) or not at all. To best
support these, we need to split some of the tests into pieces, so
that important 6502 tests aren't skipped simply because parts of the
test also exercise 65816 code.
The first step is to change the regression test naming scheme. The
old system used 1xxx for tests without project files, and 2xxx for
tests with project files. The new system uses 1xxxN / 2xxxN, where
N indicates the CPU type: 0 for 6502, 1 for 65C02, and 2 for 65816.
For the 1xxxN tests the new value determines which CPU is used,
which allows us to move the "allops" 6502/65C02 tests into the
no-project category. For 2xxxN it just allows the 6502 and 65816
versions to have the same base name and number.
This change updates the first batch of tests. It involves minor
changes to the test harness and a whole bunch of renaming.
Correct handling of local variables. We now correctly uniquify them
with regard to non-unique labels. Because local vars can effectively
have global scope we mostly want to treat them as global, but they're
uniquified relative to other globals very late in the process, so we
can't just throw them in the symbol table and be done. Fortunately
local variables exist in a separate namespace, so we just need to
uniquify the variables relative to the post-localization symbol table.
In other words, we take the symbol table, apply the label map, and
rename any variable that clashes.
This also fixes an older problem where we weren't masking the
leading '_' on variable labels when generating 64tass output.
The code list now makes non-unique labels obvious, but you can't tell
the difference between unique global and unique local. What's more,
the default type value in Edit Label is now adjusted to Global for
unique locals that were auto-generated. To make it a bit easier to
figure out what's what, the Info panel now has a "label type" line
that reports the type.
The 2023-non-unique-labels test had some additional tests added to
exercise conflicts with local variables. The 2019-local-variables
test output changed slightly because the de-duplicated variable
naming convention was simplified.
The label localizer is now always on. The regression tests turned
it off by default, but that's no longer allowed, so the generated
output has changed for many of them. The tests themselves were not
altered.
The PseudoOpNames class is increasingly being used in situations
where mutability is undesirable. This change makes instances
immutable, eliminating the Copy() method and adding a constructor
that takes a Dictionary. The serialization code now operates on a
Dictionary instead of the class properties, but the JSON encoding is
identical, so this doesn't invalidate app settings file data.
Added an equality test to PseudoOpNames. In LineListGen, don't
reset the line list if the names haven't actually changed.
Use a table lookup for C64 character conversions. I figure that
should be faster than multiple conditionals on a modern x64 system.
Fixed a 64tass generator issue where we tried to query project
properties in a call that might not have a project available
(specifically, getting FormatConfig values out of the generator for
use in the "quick set" buttons for Display Format).
Fixed a regression test harness issue where, if the assembler reported
success but didn't actually generate output, an exception would be
thrown that halted the tests.
Increased the width of text entry fields on the Pseudo-Op tab of app
settings. The previous 8-character limit wasn't wide enough to hold
ACME's "!pseudopc". Also, use TrimEnd() to remove trailing spaces
(leading spaces are still allowed).
In the last couple of months, Win10 started stalling for a fraction
of a second when executing assemblers. It doesn't do this every
time; mostly it happens if it has been a while since the assembler
was run. My guess is this has to do with changes to the built-in
malware scanner. Whatever the case, we now change the mouse pointer
to a wait cursor while updating the assembler version cache.
We've been treating ASCII strings and instruction/data operands as
ambiguous, resolving low vs. high when generating output for the
display or assembler. This change splits it into two separate
formats, simplifying output generation.
The UI will continue to treat low/high ASCII as as single thing,
selecting the format appropriately based on the data. There's no
reason to have two radio buttons that are never both enabled.
The data operand string functions need some additional work, but
that overlaps substantially with the upcoming PETSCII changes, so
for now all strings set by the data operand editor are low ASCII.
The file format has changed again, but since there hasn't been a
release since the previous change, I'm leaving the file format
at v2. Code has been added to resolve the ASCII mode when loading
a v1 project file.
This removes some complexity from the assembly code generators.
