34ba47e71d Add W65C02S support, part 3
Modified the asm source generators and on-screen display to show the
DP arg for BBR/BBS as hex.  The instructions are otherwise treated
as relative branches, e.g. the DP arg doesn't get factored into the
cross-reference table.

ACME/cc65 put the bit number in the mnemonic, 64tass wants it to be
in the first argument, and Merlin32 wants nothing to do with any of
this because it's incompatible with the 65816.

Added an "all ops" test for W65C02.

b60dc4fee4 Add W65C02S support, part 1
We were claiming W65C02S, but it turns out that CPU has the Rockwell
extensions and the STP/WAI instructions.  We need to change existing
references to be "WDC 65C02", and add a new CPU definition for the
actual W65C02S chip.

This adds the new CPU definition, the instruction definitions for
the Rockwell extensions, and updates the selectors in project properties
and the instruction chart tool.

This change shouldn't affect any existing projects.  Still more to do
before W65C02 works though, mostly because the Rockwell instructions
introduced a new two-argument address mode that has to be handled in
various places.

f30780a9de Fix Message update when broken symbolic ref is fixed
Renaming a user label doesn't cause a re-analysis, just a display
update, because nothing structural is changing.  However, that's not
quite true when you have a reference to a non-existent label (e.g.
"LDA hoser"), and you rename a label to match (e.g. change "blah"
to "hoser").  The most obvious consequence was that the Message list,
which enumerates the broken symbolic references, was not being
updated.

We now identify broken references during the refactoring rename, and
change the reanalysis mode accordingly.

There is a deeper problem, where undoing the label rename does the
wrong thing with the previously-broken symbolic references (in the
earlier example, it "undoes" them to "blah" rather than back to
"hoser").  I added some notes about that, but it's harder to fix.

Also, clean up some code that was still treating ReanalysisScope as
if it were bit flags.

bd5b556a7f Show "ptr" for pointer use in cross-reference list
Consider:
 LDA $00 loads a value from address $00
 LDA $00,X might load from $00, or might not
 LDA ($00),Y dereferences $00 as a 16-bit pointer
 LDA ($00,X) dereferences a pointer, not necessarily from $00

When perusing the cross-reference list, it's useful to be able to
tell whether an instruction is accessing the location, using it as a
base address, or deferencing it as a pointer.  We now show "ptr" in
the list for pointer dereferences.  (We already showed "idx" for
indexed accesses.)

7c506dceb6 Add Ctrl+Enter as a way to close the LVTable edit dialog
When editing local variables, the data grid generally has the input
focus, so hitting Enter doesn't close the dialog.  Rather than play
games with the focus, just take Ctrl+Enter as a shortcut to close
the dialog (same as notes and long comments).

(I found myself hitting Ctrl+Enter automatically, and being annoyed
when it didn't work, so I figured I'd make it official.)

69a9e98a43 Split "show cycle counts" in two
The "show cycle counts in comments" setting is the only one that
affects both the on-screen display and generated source code.  This
felt a little weird, so it's now two independent settings.  This
also provided an opportunity to move it to the initial tab, so it's
easier to toggle on and off.  Overall it feels less confusing to have
two settings for essentially the same thing, because code generation
is distinct from everything else.

The "spaces between bytes" setting was moved to the Display Format
tab, which seems a better fit.

Documentation and tutorial have been updated.

Also did a little bit of cleanup in EditAppSettings.

2ec2917da5 Fix inline BRK no-no-continue flag
Inline BRK instructions have a problem similar to the one fixed
for JSR/JSL back in 63d7a487, but the same fix won't work because
JSR/JSL are assumed "continue", while BRK is assumed "no-continue",
and must therefore set a no-no-continue flag.  For now, we just
re-evaluate the BRK on every visit to the code.

A review of the previous fix revealed an opportunity to use the
NoContinueScript flag on subsequent visits to improve consistency.

ba35f88d02 Mark flags as indeterminate for inline BRK
We weren't altering the status flags after a BRK because of the
assumption that a BRK was a crash.  For an inline BRK, such as a SOS
call, execution continues.  We need to mark NVZC indeterminate or
we may incorrectly handle conditional branches that follow.

The BRK instruction now uses the same flag updater as JSR, since it's
effectively a subroutine call to unknown code.  If execution doesn't
continue across the BRK then the flags don't matter.

Updated 20182-extension-scripts to exercise this.

a2e7c88fc9 Update Apple II definitions
Added explicit widths to the 6502 vectors.

Two changes to Apple II hi-res visualization:

(1) Allow the row stride to be any value >= 1.  This is useful
when data is stored in column-major order, i.e. it's a two-byte-wide
shape, with all of the data for the first column stored before the
data for the second column.  (Set the row stride to 1, and the
column stride to the bitmap height.)

(2) Modify the layout of grids (sprite sheets and fonts), so that
we're closer to square when the item counts is low.  Otherwise the
thumbnail just looks like a dashed line.  (This one is strictly
cosmetic.)

288a857e47 Change PLP handling
The "smart" PLP handler tries to recover the flags from an earlier
PHP.  The non-smart version just marks all the flags as indeterminate.
This doesn't work well on the 65816 in native mode, because having
the M/X flags in an indeterminate state is rarely what you want.

Code rarely uses PLP to reset the flags to a specific state, preferring
explicit SEP/REP.  The analyzer is more likely to get the correct
answer by simply leaving the flags in their prior state.

A test case has been added to 20052-branches-and-banks, which now has
"smart PLP" disabled.

cb6ceafd73 Make operand wrap length configurable
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.

195c93a94a Reboot sandbox when required
Another chapter in the never-ending AppDomain security saga.

If a computer goes to sleep while SourceGen is running with a project
open, life gets confusing when the system wakes up.  The keep-alive
timer fires and a ping is sent to the remote AppDomain, successfully.
At the same time, the lease expires on the remote side, and the objects
are discarded (apparently without bothering to query the ILease object).
This failure mode is 100% repeatable.

Since we can't prevent sandbox objects from disappearing, we have to
detect and recover from the problem.  Fortunately we don't keep any
necessary state on the plugin side, so we can just tear the whole
thing down and recreate it.

The various methods in ScriptManager now do a "health check" before
making calls into the plugin AppDomain.  If the ping attempt fails,
the AppDomain is "rebooted" by destroying it and creating a new one,
reloading all plugins that were in there before.  The plugin binaries
*should* still be in the PluginDllCache directory since the ping failure
was due to objects being discarded, not AppDomain shutdown, and Windows
doesn't let you mess with files that hold executable code.

A new "reboot security sandbox" option has been added to the DEBUG
menu to facilitate testing.

The PluginManager's Ping() method gets called more often, but not to
the extent that performance will be affected.

This change also adds a finalizer to DisasmProject, since we're relying
on it to shut down the ScriptManager, and it's relying on callers to
invoke its cleanup function.  The finalizer throws an assertion if the
cleanup function doesn't get called.

9aaa37a23c Add Cxxx I/O locations in bank $e0 for Apple IIgs
On an Apple IIgs, the memory-mapped I/O locations are actually in
bank $e0, shadow-copied to bank $00.  This adds a copy of the
relevant definitions from Cxxx-IO.sym65, with the addresses in bank
$e0 and "_GS" appended to the labels.

This is now included by default for the Apple IIgs system defintions.

(I thought about just adding them to Cxxx-IO.sym65, but then they
pollute the namespace for 8-bit systems.  Stripping them out at run
time got a little complicated because the platform symbols are only
loaded once, and we'd have to reload them every time the CPU definition
changed.  Further, there are a few aliases provided as constants, and
constants are allowed to be 32 bits on all systems, so those can't be
stripped.  Rather than defining a new definition I figured it was
just easier to have a second file.  Maintenance shouldn't be too taxing,
as definitions for 40-year-old machines don't change all that often.)

(I also thought about trying to make the address mirroring stuff work
for me here, but that would result in accesses being made to the
canonical address with an offset of +$e00000, which looks awful.)

e82dc31da6 Move Disk ][ defs into separate platform symbol file
The Disk ][ I/O locations are generally accessed as an offset, using
something like "LDA $C08n,X".  However the range from $C080-C08F is
already used for language card in slot 0.  SourceGen doesn't have a
way to distinguish between indexed and direct accesses, and even if
it did there's no way to separate one peripheral card from another
without knowing the contents of the CPU register.

As a workaround, the Disk ][ definitions are now in a separate symbol
file.  When loaded, the definitions replace the base slot 0 equates.

I figure Disk ][ accesses are more common than language card
manipulation, so I'm making it a default for new projects.  Existing
projects that reference the Disk ][ symbols (which existed, but as
constants) will need to be updated to include the new .sym65.

cc6ebaffc5 Update relocation data handling
When we have relocation data available, the code currently skips the
process of matching an address with a label for a PEA instruction when
the instruction in question doesn't have reloc data.  This does a
great job of separating code that pushes parts of addresses from code
that pushes constants.

This change expands the behavior to exclude instructions with 16-bit
address operands that use the Data Bank Register, e.g. "LDA abs"
and "LDA abs,X".  This is particularly useful for code that accesses
structured data using the operand as the structure offset, e.g.
"LDX addr" / "LDA $0000,X"

The 20212-reloc-data test has been updated to check the behavior.

longer always the same as the PBR.  This just required adding "B=K"

6ce2cc0b58 Fix label-trampling bug in reloc data handler
If code accesses the high/low parts of a 32-bit address value with
no label, it auto-generates labels for addr+2 and addr.  The reloc
handler was replacing the unformatted bytes with a single multi-byte
format, hiding the label at addr+2.

The easy fix is to have the reloc data handler skip the entry.  This
is less useful than other approaches, but much simpler.

Added a test to 20212-reloc-data.

18e6951f17 Add Data Bank Register management, part 1
On the 65816, 16-bit data access instructions (e.g. LDA abs) are
expanded to 24 bits by merging in the Data Bank Register (B).  The
value of the register is difficult to determine via static analysis,
so we need a way to annotate the disassembly with the correct value.
Without this, the mapping of address to file offset will sometimes
be incorrect.

This change adds the basic data structures and "fixup" function, a
functional but incomplete editor, and source for a new test case.

44522dc2f2 Performance tweak
The Visual Studio performance profiler showed the FormatDescriptor
equality test being called quite a lot.  The test was vs. null, so
a simple change from "==" to "is" improved performance dramatically.

Fixing the underlying issue with a better data structure is still
important, but this provided a big boost with little effort.

f4fe3af050 Fix application of reloc info in data areas
The test wasn't correctly excluding instructions, so it was possible
to create a situation where a two-byte data item had an instruction
starting in the second byte.

We also weren't checking the length of the instruction to ensure that
it was wider than the reloc data.  This could get weird for an
immediate constant when the M/X flags are wrong.  When in doubt, don't
overwrite.

bc15178a8e Tweak M/X/E flag handling
The decision of how to handle indeterminate M/X flag values is made in
StatusFlags.  This provides consistent behavior throughout the app.
This was being done for M/X but not for E.

This change also renames the M/X tests, prefixing them with "Is" to
emphasize that they are boolean rather than tri-state.

There should be no change in behavior from this.

4e70edc90c Add 20212-reloc-data test
This test exercises the relocation data feature.  The test file is
generated from a multi-segment OMF file that was hex-edited to have
specific attributes (see 20212-reloc-data-lnk.S for instructions).
The test also serves as a way to exercise the OMF converter.

Also, implement the Bank Relative flag.

8d291ba21e Fix bank for AbsInd and AbsIndLong addressing
The Absolute Indirect and Absolute Indirect Long addressing modes
(e.g. "JMP (addr)" and "JMP [addr]") are 16-bit values in bank 0.
The code analyzer was placing them in the program bank, which
meant the wrong symbol was being used.

Also, tweak some docs.

0fa77cba75 Apply relocation data to unformatted data
Works well for things like jump tables.  Seeing a bunch of these
scattered in a chunk of data is a decent signal that it's actually
code.

In a bold move, we now exclude PEA operands from auto-label gen when
they don't have relocation data.  This is very useful for things
like Int2Hex for which constants are typically pushed with PEA.

Reworked the "use reloc data" setting so it defaults to false and is
explicitly set to true when converting OMF.  This provides a minor
optimization since we now check the boolean and skip doing a lookup
in an empty table.

d58b747571 Use relocation data to format instruction operands
This was a relatively lightweight change to confirm the usefulness
of relocation data.  The results were very positive.

The relatively superficial integration of the data into the data
analysis process causes some problems, e.g. the cross-reference table
entries show an offset because the code analyzer's computed operand
offset doesn't match the value of the label.  The feature should be
considered experimental

The feature can be enabled or disabled with a project property.  The
results were sufficiently useful and non-annoying to make the setting
enabled by default.

190f68d1f8 Add code hints to OMF jump tables
We now put a code hint on the JML instruction in each jump table

recognized as code, since a dynamic segment won't otherwise be
referenced.

Also, fiddle with the note/comment formatting some more.

fdd2bcf847 Fix some 65816 code generation issues
Two basic problems:

(1) cc65, being a one-pass assembler, can't tell if a forward-referenced
label is 16-bit or 24-bit.  If the operand is potentially ambiguous,
such as "LDA label", we need to add an operand width disambiguator.
(The existing tests managed to only do backward references.)

(2) 64tass wants the labels on JMP/JSR absolute operands to have 24-bit
values that match the current program bank.  This is the opposite of
cc65, which requires 16-bit values.  We need to distinguish PBR vs.
DBR instructions (i.e. "LDA abs" vs. "JMP abs") and handle them
differently when formatting for "Common".

Merlin32 doesn't care, and ACME doesn't work at all, so neither of
those needed updating.

The 20052-branches-and-banks test was expanded to cover the problematic
cases.

86be31a02f Rewrite OMF jump table segments
The GS/OS loader initializes the calls with JSLs to a loader entry
point, and replaces them with JMLs to code in dynamic segments when
the segments are loaded.  Since we have all the segments loaded at
once, we can just rewrite them to be JMLs immediately.

58a415bd93 Finish initial work on OMF file handling
Generate multiple .ORG directives for segments that span multiple
banks.  Some assemblers don't like it when things cross.  This is
pretty rare (Cryllan Mission is an example).

Conversion of OMF Load files to a data/project pair is generally
working.  The 65816 source code generators need some work though.

c47beffcee Add Export feature to visualization editor
It's nice to be able to save images from the visualization editor
for display elsewhere.  This can be done during HTML export, but
that's inconvenient when you just want one image, and doesn't allow
the output size to be specified.

This change adds an Export button to the Edit Visualization dialog.
The current bitmap, wireframe, or wireframe animation can be saved
to a GIF image.  A handful of sizes can be selected from a pop-up
menu.

b43fd07688 Split 2002x-operand-formats test
My original goal was to add a sign-extended decimal format, but that
turned out to be awkward.  It works for data items and instructions
with immediate operands (e.g. "LDA #-1"), but is either wrong or
useless for address operands, since most assemblers treat integers
as 32-bit values.  (LDA -1 is not LDA $FFFF, it's LDA $FFFFFFFF,
which is not useful unless your asm is doing an implicit mod.)

There's also a bit of variability in how assemblers treat negative
values, so I'm shelving the idea for now.  I'm keeping the updated
tests, which are now split into 6502 / 65816 parts.

Also, updated the formatter to output all decimal values as unsigned.
Most assemblers were fine with negative values, but 64tass .dword
insists on positive.  Rather than make the opcode conditional on the
value's range, we now just always output unsigned decimal, which
all current assemblers accept.

bb830a29db Add Navigate > Jump to Operand
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.
