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.
