This is still an "experimental" feature, but it's getting expanded
a bit. The implementation now lives in its own class. An "export"
feature that generates SGEC data has been added. The file extension
has been changed from ".sgec" to ".txt" to make it simpler to edit
under Windows.
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.
Added generation of the relocation dictionary and constant body for
segments in Load files.
Also, don't reject files with v1 segments (whose length is specified
as a block count) just because the EOF isn't a multiple of 512 bytes.
Some executables don't pad out the last block.
Various tweaks to output formatting.
Added generation of info/error messages to segment parser, which
are displayed in the main OMF viewer window.
Added segment viewer window, which opens when a segment entry in the
viewer list is double-clicked. Currently shows the "raw" header
fields, with place-holder UI for additional stuff.
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.
Moved X/Y/Z rotation out of the plugin, since it has nothing to do
with the plugin at all. (Backface removal and perspective projection
are somewhat based on the data contents, as is the choice for
whether or not they should be options.)
Added sliders for X/Y/Z rotation. Much more fun that way.
Renamed VisualizationAnimation to VisBitmapAnimation, as we're not
going to use it for wireframe animation. Created a new class to
hold wireframe animation data, which is really just a reference to
the IVisualizationWireframe so we can generate an animated GIF
without having to pry open the plugin again.
Renamed the "frame-delay-msec" parameter, which should start with
an underscore to ensure it doesn't clash with plugin parameters.
If we don't find it with an underscore we check again without for
backward compatibility.
We extract the data from the wireframe visualization, perform a
trivial transform, and display it. The perspective vs.
orthographic flag in the parameters is respected. (No rotation or
backface removal yet.)
Also, increased the thumbnail sizes in the visualization set editor
list from 48x48 to 64x64, because the nearest-pixel-scaled 48x48
looks nasty when used for wireframes.
The tool allows you to cut a piece out of a file by specifying an
offset and a length. A pair of hex dumps helps you verify that the
positions are correct.
Also, minor cleanups elsewhere.
Bitmap animations are composed of a sequence of other visualizations.
This is all well and good until a visualization is deleted, at which
point all animations in all sets in the entire project have to be
checked and potentially changed, and perhaps even removed (if all of
the animation's members have been removed). This turns out to be
kind of annoying to deal with, but it's better to deal with it in
code than force the user to manually update broken animations.
This change adds thumbnails for the animations, currently generated
by offscreen composition. This approach doesn't work quite right.
This adds a new class and a rough GUI for the editor. Animated
visualizations take a collection of bitmaps and display them in
sequence. (This will eventually become an animated GIF.)
Fixed the issue where changes to tags in the set currently being
edited weren't visible to the tag uniqueness check when editing other
items in the same set.
The Visualization and Visualization Set editors are now fully
functional. You can create, edit, and rearrange sets, and they're
now stored in the project file.
Basic infrastructure for taking a list of parameters from a plugin
and turning it into a collection of UI controls, merging in values
from a Visualization object. Doesn't yet do anything useful.
WPF makes the hard things easy and the easy things hard. This was
a hard thing, so it was easy to do (with some helpful sample code).
Yay WPF?
This adds a window that displays all of the instructions for a
given CPU in a summary grid. Undocumented instructions are
included, but shown in grey italics.
Also, tweaked AppSettings to not mark itself as dirty if a "set"
operation doesn't actually change anything.
This converts the "problem list viewer" tool to a grid that appears
below the code list view when non-empty. Not all messages are
problems, so it's being renamed to "message list".
Most of SourceGen uses standard WPF controls, which get their default
style from the system theme. The main disassembly list uses a
custom style, and always looks like the Windows default theme.
Some people greatly prefer white text on a black background, so we
now provide a way to get that. This also requires muting the colors
used for Notes, since those were chosen to contrast with black text.
This does not affect anything other than the ListView used for
code, because everything else can be set through the Windows
"personalization" interface. We might want to change the way the
Notes window looks though, to avoid having glowing bookmarks on
the side.
The analyzer sometimes runs into things that don't seem right, like
hidden labels or references to non-existent symbols, but has no way
to report them. This adds a problem viewer.
I'm not quite ready to turn this into a real feature, so for now it's
a free-floating window accessed from the debug menu.
Also, updated some documentation.
Ported the column width stuff from EditAppSettings, which it turns
out can be simplified slightly.
Moved the clipboard copy code out into its own class.
Disabled "File > Print", which has never done anything and isn't
likely to do anything in the near future.
Also, added a note to 2019-local-variables about a test case it
should probably have.
Rearrange the UI elements, and convert the code-behind to a more
XAML-style form. The basic stuff works, but the old "shortcut"
system is still in the process of being replaced.
The code that checked to see if a data target was inside a data
operand wasn't going all the way back to the start of the file.
It was also failing to stop when it should, wasting time.
The anattrib validation method has code that avoids a false-positive
on certain complex embedded instruction arrangements. This was also
preventing it from seeing a transition from a data area to the
middle of an instruction (caused by issue #45).
Variables are now handled properly end-to-end, except for label
uniquification. So cc65 and ACME can't yet handle a file that
redefines a local variable.
This required a bunch of plumbing, but I think it came out okay.
String operands used to be simple -- each line had 62 characters
plus two hard-coded non-ASCII delimiters -- but now we're mixing
character and hex data, so we can't use simple math to tell where
the lines will break. We want to render them and keep the result
around until some dependency changes, e.g. different delimiters
or a change to the pseudo-op table.
Also, cleaned up LineListGen a little. It had some methods that
were declared static because they were expected to be shared, but
that never happened.
Also, fixed a bug in GatherEntityCounts where multi-line items were
being scanned multiple times.
Remove left/right arrow PNGs. Remove duplicate copies of icon.
Tweak some comments. Set application icon. Adjust padding on
group boxes in first tab of app settings.
This generalizes the string pseudo-operand formatter, moving it into
the Asm65 library. The assembly source generators have been updated
to use it. This makes the individual generators simpler, and by
virtue of avoiding "test runs" should make them slightly faster.
This also introduces byte-to-character converters, though we're
currently still only supporting low/high ASCII.
Regression test output is unchanged.
SourceGen creates "auto" labels when it finds a reference to an
address that doesn't have a label associated with it. The label for
address $1234 would be "L1234". This change allows the project to
specify alternative label naming conventions, annotating them with
information from the cross-reference data. For example, a subroutine
entry point (i.e. the target of a JSR) would be "S_1234". (The
underscore was added to avoid confusion when an annotation letter
is the same as a hex digit.)
Also, tweaked the way the preferred clipboard line format is stored
in the settings file (was an integer, now an enumeration string).
Most tests pass, but 2007-labels-and-symbols fails because the
expressions recognized by 64tass don't match up with either of the
other assemblers.
This is currently using a workaround for the local label syntax.
64tass uses '_' as the prefix, which is unfortunate since SourceGen
explicitly allowed underscores in labels. (So does 64tass for that
matter, but it treats labels specially when the '_' comes first.)
We will need to rename any non-local user labels that start with '_'.
(issue #16)
Rather than have each assembler get its own app config string for
the cross-assembler executable, we now have a collection of per-
assembler config items, of which the executable path name is one
member. The Asm Config tab has an auto-generated pop-up to select
the assembler.
The per-assembler settings block is serialized with the rather
unpleasant JSON-in-JSON approach, but nobody should have to look
at it.
This also adds assembler-specific column widths to the settings
dialog, though they aren't actually used yet.
Each supported assembler has an IGenerator interface and an
IAssembler interface. They're still two separate classes, but now
both are implemented in the same source file. (They'll probably
stay separate classes, since the two have little interaction.)
I'm keeping the "Asm*" filename. Seems the more natural fit.
Also, changed AssemblerInfo to try to get all assembler-specific
stuff into a single table.
