Before:
Hint As Code Entry Point
Hint As Data Start
Hint As Inline Data
Remove Hints
After:
Tag Address As Code Start Point
Tag Address As Code Stop Point
Tag Bytes As Inline Data
Remove Analyzer Tags
The goal is to reduce confusion. The old nomenclature was causing
problems because it's inaccurate -- they're directives, not hints --
and made it look like you need to mark data items explicitly. The
new action names emphasize the idea that you should be tagging a
single address for start/stop, not blanketing a region.
This change updates the user interface, manual, and tutorials, but
does not change how the items are referred to in code, and does not
change how the program works.
(issue #89)
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.
Sometimes you just want to turn cycle counts on for a bit, and going
through app settings is tiresome. Now there's a toolbar checkbox
for it. The icon isn't ideal, but it'll do.
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.
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.
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.
Implemented "smart" PLB handling. If we see PHK/PLB, or 8-bit
LDA imm/PHA/PLB, we create a data bank change item. The feature
can be disabled with a project property.
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.
Updated documentation for non-unique label changes. Added a new
section to tutorial #1.
Updated examples to use non-unique labels and variable tables.
Tweaked the EditLabel radio button names.
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 last two tabs in the Edit App Settings dialog have "quick set"
buttons configure all fields for a particular assembler, or reset
them to default values. The previous UI was a little annoying,
because you had to pick something from the combo box and then hit
"set" to push the change. It was also confusing, because if you
came back later the combo box was just set to the first entry, not
the thing you picked last.
Now, picking an entry from the combo box immediately updates all
fields. The combo box selection is set to reflect the actual
contents (so if you set everything just right, the combo box will
change to a specific assembler). If nothing matches, a special
entry labeled "Custom" is selected.
Also, rearranged the tutorial sections in the manual so the
address table formatting comes last, and appears in the local TOC.
The Find box now has forward/backward radio buttons. Find Next
searches forward, and Find Previous searches backward, regardless
of the direction of the initial search.
The standard key sequence for "find previous" is Shift+F3. The WPF
ListView has some weird logic that does something like: if you hit
a key, and the selection changes, and the shift key was held down,
then you must have meant to select a range. So Shift+F3 often (but
not always) selects a range. I think this might be fixable if I can
figure out how ListView keeps track of the current keyboard
navigation position (which is not the same as the selection). For
now I'm working around the problem by using Ctrl+F3 to search.
Yay WPF.
The "add platform symbol file" and "add extension script" buttons
create a file dialog with the initial directory set to the
RuntimeData directory inside the SourceGen installation directory.
This is great if you're trying to add a file from the platform
definitions, but annoying if you're trying to add it from the
project directory.
It's really convenient to not have to hunt around though, so now
there are two buttons: one for platform, one for project. The
latter is disabled if the project is new and hasn't been saved yet.
Handle situation where a symbol wraps around a bank. Updated
2021-external-symbols for that, and to test the behavior when file
data and an external symbol overlap.
The bank-wrap test turned up a bug in Merlin 32. A workaround has
been added.
Updated documentation to explain widths.
HTML output should have had double quotes around internal anchors.
(Chrome and Edge didn't complain, but the w3c validator wasn't
happy.)
Made the text areas in the load-time problem report dialogs
scrollable.
Updated the manual.
Also, removed "include symbol table" from export dialog. You can
exclude the table by removing it from the template, which right
now you'd need to do anyway to get rid of the H2 header and other
framing. To make this work correctly as an option we'd need to
parse the "div" in the template file and strip the whole section,
or split the template into multiple parts that get included as
needed. Not worth doing the work until we're sure it matters.
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).
Before you could choose between Merlin-style and generic. Now
there's a combo box that lets you choose Merlin, cc65, or
"common", the latter being used for 64tass.
Once upon a time, symbol files and extension scripts could only be
defined in the RuntimeData directory, so having the documentation
there made sense. Since both of these things can now be defined in
project directories, the documentation belongs in the manual.
