Label rework, part 5 Implemented assembly source generation of non-unique local labels. The new 2023-non-unique-labels test exercises various edge cases (though we're still missing local variable interaction). The format of uniquified labels changed slightly, so the expected output of 2012-label-localizer needed to be updated. This changes the "no opcode mnemonics" and "mask leading underscores" functions into integrated parts of the label localization process.

Label rework, part 6 Correct handling of local variables. We now correctly uniquify them with regard to non-unique labels. Because local vars can effectively have global scope we mostly want to treat them as global, but they're uniquified relative to other globals very late in the process, so we can't just throw them in the symbol table and be done. Fortunately local variables exist in a separate namespace, so we just need to uniquify the variables relative to the post-localization symbol table. In other words, we take the symbol table, apply the label map, and rename any variable that clashes. This also fixes an older problem where we weren't masking the leading '_' on variable labels when generating 64tass output. The code list now makes non-unique labels obvious, but you can't tell the difference between unique global and unique local. What's more, the default type value in Edit Label is now adjusted to Global for unique locals that were auto-generated. To make it a bit easier to figure out what's what, the Info panel now has a "label type" line that reports the type. The 2023-non-unique-labels test had some additional tests added to exercise conflicts with local variables. The 2019-local-variables test output changed slightly because the de-duplicated variable naming convention was simplified.

Fix various local variable de-duplication bugs In 1.5.0-dev1, as part of changes to the way label localization works, the local variable de-duplicator started checking against a filtered copy of the symbol table. Unfortunately it never re-generated the table, so a long-lived LocalVariableLookup (like the one used by LineListGen) would set up the dup map wrong and be inconsistent with other parts of the program. We now regenerate the table on every Reset(). The de-duplication stuff also had problems when opcodes and operands were double-clicked on. When the opcode is clicked, the selection should jump to the appropriate variable declaration, but it wasn't being found because the label generated in the list was in its original form. Fixed. When an instruction operand is double-clicked, the instruction operand editor opens with an "edit variable" shortcut. This was showing the de-duplicated name, which isn't necessarily a bad thing, but it was passing that value on to the DefSymbol editor, which thought it was being asked to create a new entry. Fixed. (Entering the editor through the LvTable editor works correctly, with nary a de-duplicated name in sight. You'll be forced to rename it because it'll fail the uniqueness test.) References to de-duplicated local variables were getting lost when the symbol's label was replaced (due largely to a convenient but flawed shortcut: xrefs are attached to DefSymbol objects). Fixed by linking the XrefSets. Given the many issues and their relative subtlety, I decided to make the modified names more obvious, and went back to the "_DUPn" naming strategy. (I'm also considering just making it an error and discarding conflicting entries during analysis... this is much more complicated than I expected it to be.) Quick tests can be performed in 2019-local-variables: - go to +000026, double-click on the opcode, confirm sel change - go to +000026, double-click on the operand, confirm orig name shown in shortcut and that shortcut opens editor with orig name - go to +00001a, down a line, click on PROJ_ZERO_DUP1 and confirm that it has a single reference (from +000026) - double-click on var table and confirm editing entry
