Split "edit local variable table" into "create" and "edit prior".
The motivation is to allow the user to make changes to the most
recently defined table without having to go search for it. Having
table creation be an explicit action, rather than something that
just happens if you edit a table that isn't there, feels reasonable.
Show table offset in LV table edit dialog, so if you really want
to go find it there's a (clumsy) way to do so.
Increased the maximum width of a variable from 4 to 8. (This is
entirely arbitrary.)
Implemented local variable editing. Operands that have a local
variable reference, or are eligible to have one, can now be edited
directly from the instruction operand edit dialog.
Also, updated the code list double-click handler so that, if you
double-click on the opcode of an instruction that uses a local
variable reference, the selection and view will jump to the place
where that variable was defined.
Also, tweaked the way the References window refers to references
to an address that didn't use a symbol at that address. Updated
the explanation in the manual, which was a bit confusing.
Also, fixed some odds and ends in the manual.
Also, fixed a nasty infinite recursion bug (issue #47).
We now generate FormatDescriptors with WeakSymbolRefs for direct
page references that match variable table entries.
LocalVariableTable got a rewrite. We need to be unique in both
name and address, but for the address we have to take the width into
account as well. We also want to sort the display by address
rather than name. (Some people might want it sorted by name, but
we can worry about that some other time.)
Updated the DefSymbol editor to require value uniqueness. Note
addresses and constants exist in separate namespaces.
The various symbols are added to the SymbolTable so that uniqueness
checks work correctly. This also allows the operand generation to
appear to work, but it doesn't yet handle redefinition of symbols.
This involved adding a list to the DisasmProject, creating a new
UndoableChange type, and writing the project file serialization
code. While doing the latter I realized that the new Width field
was redundant with the FormatDescriptor Length field, and removed it.
I added a placeholder line type, but we're not yet showing the
table in the display list. (To edit the tables you just have to
know where they are.)
The table editor is now editing the table, and the DefSymbol editor
now asks for the Width data when editing a local var.
This also moves EditDefSymbol closer to proper WPF style, with
bound properties for the input fields.
No changes yet to serialization or analysis.
