Updated project file format to save the new map entries.
Tweaked appearance of .arend directives to show the .arstart address
in the operand field. This makes it easier to match them up on screen.
Also, add a synthetic comment on auto-generated .arstart entries.
Added .arstart/.arend to the things that respond to Jump to Operand
(Ctrl+J). Selecting one jumps to the other end. (Well, it jumps
to the code nearest the other, which will do for now.)
Added a menu item to display a text rendering of the address map.
Helpful when things get complicated.
Modified the linear map iterator to return .arend items with the offset
of the last byte in the region, rather than the first byte of the
following region. While the "exclusive end" approach is pretty
common, it caused problems when updating the line list, because it
meant that the .arend directives were outside the range of offsets
being updated (and, for directives at the end of the file, outside
the file itself). This was painful to deal with for partial updates.
Changing this required some relatively subtle changes and annoyed some
of the debug assertions, such as the one where all Line items have
offsets that match the start of a line, but it's the cleaner approach.
Reimplemented "set address" dialog as the Address Region Editor. The
new dialog configures itself differently depending on whether the user
appears to be trying to create, edit, or resize a region. Each mode
has two options, to allow the user to choose between floating and fixed
end points.
The old dialog would allow you to delete an address override by erasing
the address field. Now there's an explicit "delete region" button.
Changed the SetAddress undoable change function to use AddressMapEntry
objects.
We now show detailed information on .arstart/.arend in the Info window
when the lines are selected.
PRG files are now created without specifying a region for the first
two bytes, so the load address exists in a NON_ADDR hole. Fixed a
couple of issues to make that look right.
Split ".org" into ".arstart" and ".arend" (address range start/end).
Address range ends are now shown in the code list view, and the
pseudo-op can be edited in app settings. Address range starts are
now shown after notes and long comments, rather than before, which
brings the on-screen display in sync with generated code.
Reworked the address range editor UI to include the new features.
The implementation is fully broken.
More changes to the AddressMap API, putting the resolved region length
into a separate ActualLength field. Added FindRegion(). Renamed
some things.
Code generation changed slightly: the blank line before a region-end
line now comes after it, and ACME's "} ;!pseudopc" is now just "}".
This required minor updates to some of the regression test results.
AddressMap API reshuffle. Added "pre-label" to class and API. Split
AddressMapEntry into two parts to make it clear when FLOATING_LEN
has been resolved.
Updated display line list generator to use in-line linear map
traversal. Previous approach was to walk through the list of regions
in a second pass, inserting .ORG directives, but that was awkward
and is no longer needed.
This is the first step toward changing the address region map from a
linear list to a hierarchy. See issue #107 for the plan.
The AddressMap class has been rewritten to support the new approach.
The rest of the project has been updated to conform to the new API,
but feature-wise is unchanged. While the map class supports
nested regions with explicit lengths, the rest of the application
still assumes a series of non-overlapping regions with "floating"
lengths.
The Set Address dialog is currently non-functional.
All of the output for cc65 changed because generation of segment
comments has been removed. Some of the output for ACME changed as
well, because we no longer follow "* = addr" with a redundant
pseudopc statement. ACME and 65tass have similar approaches to
placing things in memory, and so now have similar implementations.
These were being overlooked because they didn't actually cause
anything to happen (a no-op .ORG sets the address to what it would
already have been). The assembly source generator works in a way
that causes them to be skipped, so everybody was happy.
This seemed like the sort of thing that was likely to cause problems
down the road, however, so we now split regions correctly when a
no-op .ORG is encountered. This affects the uncategorized data
analyzer and selection grouping.
This changed the behavior of the 2004-numeric-types test, which was
visibly weird in the UI but generated correct output.
Added the 2024-ui-edge-cases test to provide a place to exercise
edge cases when testing the UI by hand. It has some value for the
automated regression test, so it's included there.
Also, changed the AddressMapEntry objects to be immutable. This
is handy when passing lists of them around.
If you have a single line selected, Set Address adds a .ORG directive
that changes the addresses of all following data, until the next .ORG
directive is reached. Sometimes code will relocate part of itself,
and it's useful to be able to set the address at the end of the block
to what it would have been before the .ORG change.
If you have multiple lines selected, we now add the second .ORG to
the offset that follows the last selected line.
Also, fixed a bug in the Symbol value updater that wasn't handling
non-unique labels correctly.
The current AddressMap is now passed into the plugin manager, which
wraps it in an AddressTranslate object and passes that to the
plugins at Prepare() time. This allows plugins to convert addresses
to offsets, making it possible to format complex structures.
This breaks existing plugins.
