Handle variable labels that are duplicates of non-variables After thrashing around a bit, I had to choose between making the uniquifier more complicated, or making de-duplication a separate step. Since I don't really expect duplicates to be a thing, I went with the latter. Updated the regression test.

;Edited to have duplicate labels (PROJ_ZERO, DPCODE).
Add 2019-local-variables test This hits most of the edge cases, but doesn't exercise the two duplicate name situations (var name same as user label, var name same as project/platform symbol). Also, fixed a bug in the EditDefSymbol uniqueness check where it was comparing a symbol to itself.

Operand for ".enc" should be in double quotes The 64tass assembler was generating a warning.

Work around two assembler issues Most assemblers end local label scope when a global label is encountered. cc65 takes this one step further by ending local label scope when constants or variables are defined. So, if we have a variable table with a nonzero number of entries, we want to create a fake global label at that point to end the scope. Merlin 32 won't let you write " LDA #',' ". For some reason the comma causes an error. IGenerator now has a "tweak operand format" interface that lets us fix that.

.cdef $20,$7e,$20
Change some EQU handling Changed the sort order on EQU lines so that constants come before address definitions. This caused trivial changes to three of the regression tests. Added the ability to jump directly to an EQU line when an opcode is double-clicked on.

CONST_ZERO = $f0 ;project const
Add a blank line between constants and addresses In the assembler output, add a blank line between the constants and addresses in the long list of equates. The earlier change that corrected the BIT instruction caused test 2009-branches-and-banks to fail, because it was relying on the idea that BIT made the carry flag indeterminate. Changing a BCC to a BVS restored the desired behavior.

Apply project/platform symbols to Numeric/Address data operands A ".dd2 <address>" item would get linked to an internal label, but references to external addresses weren't doing the appropriate search through the platform/project symbol list. This change altered the output of the 2019-local-variables test. The previous behavior was restored by disabling "nearby" symbol matching in the project properties. Updated the "lookup symbol by address" function to ignore local variables. Also, minor updates to Applesoft and F8-ROM symbol tables.

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

Expand 20152-local-variables test Added a compiled C implementation of strlen(). The most interesting part about this is that it references a 16-bit value via direct-page address $ff, which means you'd want a local variable with address=$ff and width=2. The current UI prevents this.
