Progress toward 64tass support Most tests pass, but 2007-labels-and-symbols fails because the expressions recognized by 64tass don't match up with either of the other assemblers. This is currently using a workaround for the local label syntax. 64tass uses '_' as the prefix, which is unfortunate since SourceGen explicitly allowed underscores in labels. (So does 64tass for that matter, but it treats labels specially when the '_' comes first.) We will need to rename any non-local user labels that start with '_'. (issue #16)

.cpu "65816"
Fix 64tass output for non-loadable files 64tass wants to place its output into a 64KB region of memory, starting at the address "*" is set to, and continuing without wrapping around the end of the bank. Some files aren't meant to be handled that way, so we need to generate the output differently. If the file's output fits nicely, it's considered "loadable", and is generated in the usual way. If it doesn't, it's treated as "streamable", and the initial "* = addr" directive is omitted (leaving "*" at zero), and we go straight to ".logical" directives. 65816 code with an initial address outside bank 0 is treated as "streamable" whether or not the contents fit nicely in the designated 64K area. This caused a minor change to a few of the 65816 tests. A new test, 20240-large-overlay, exercises "streamable" by creating a file with eight overlapping 8KB segments that load at $8000. While the file as a whole fits in 64KB, it wouldn't if loaded at the desired start address. Also, updated the regression test harness to report assembler failure independently of overall test failure. This makes it easier to confirm that (say) ACME v0.96.4 still works with the code we generate, even though it doesn't match the expected output (which was generated for v0.97). (problem was raised in issue #98)

Improve handling of C64 PRG header C64 PRG files are pretty common. Their salient feature is that they start with a 16-bit value that is used as the load address. The value is commonly generated by the assembler itself, rather than explicitly added to the source file. Not all assemblers know what a PRG file is, and some of them handle it in ways that are difficult to guarantee in SourceGen. ACME adds the 16-bit header when the output file name ends in ".prg", cc65 uses a modified config file, 64tass uses a different command-line option, and Merlin 32 has no idea what they are. This change adds PRG file detection and handling to the 64tass code generator. Doing so required making a few changes to the gen/asm interfaces, because we now need to have the generator pass additional flags to the assembler, and sometimes we need code generation to start somewhere other than offset zero. Overall the changes were pretty minor. The 20042-address-changes test needed a 6502-only variant. A new test (20040-address-changes) has been added and given a PRG header. As part of this change the 65816 variant was changed to use addresses in bank 2, which uncovered a code generation bug that this change also fixes. The 64tass --long-address flag doesn't appear to be necessary for files <= 65536 bytes long, so we no longer emit it for those. (issue #90)

Allow explicit widths in project/platform symbols, part 3 Implement multi-byte project/platform symbols by filling out a table of addresses. Each symbol is "painted" into the table, replacing an existing entry if the new entry has higher priority. This allows us to handle overlapping entries, giving boosted priority to platform symbols that are defined in .sym65 files loaded later. The bounds on project/platform symbols are now rigidly defined. If the "nearby" feature is enabled, references to SYM-1 will be picked up, but we won't go hunting for SYM+1 unless the symbol is at least two bytes wide. The cost of adding a symbol to the symbol table is about the same, but we don't have a quick way to remove a symbol. Previously, if two platform symbols had the same value, the symbol with the alphabetically lowest label would win. Now, the symbol defined in the most-recently-loaded file wins. (If you define two symbols with the same value in the same file, it's still resolved alphabetically.) This allows the user to pick the winner by arranging the load order of the platform symbol files. Platform symbols now keep a reference to the file ident of the symbol file that defined them, so we can show the symbols's source in the Info panel. These changes altered the behavior of test 2008-address-changes, which includes some tests on external addresses that are close to labeled internal addresses. The previous behavior essentially treated user labels as being 3 bytes wide and extending outside the file bounds, which was mildly convenient on occasion but felt a little skanky. (We could do with a way to define external symbols relative to internal symbols, for things like the source address of code that gets relocated.) Also, re-enabled some unit tests. Also, added a bit of identifying stuff to CrashLog.txt.

Improve handling of C64 PRG header C64 PRG files are pretty common. Their salient feature is that they start with a 16-bit value that is used as the load address. The value is commonly generated by the assembler itself, rather than explicitly added to the source file. Not all assemblers know what a PRG file is, and some of them handle it in ways that are difficult to guarantee in SourceGen. ACME adds the 16-bit header when the output file name ends in ".prg", cc65 uses a modified config file, 64tass uses a different command-line option, and Merlin 32 has no idea what they are. This change adds PRG file detection and handling to the 64tass code generator. Doing so required making a few changes to the gen/asm interfaces, because we now need to have the generator pass additional flags to the assembler, and sometimes we need code generation to start somewhere other than offset zero. Overall the changes were pretty minor. The 20042-address-changes test needed a 6502-only variant. A new test (20040-address-changes) has been added and given a PRG header. As part of this change the 65816 variant was changed to use addresses in bank 2, which uncovered a code generation bug that this change also fixes. The 64tass --long-address flag doesn't appear to be necessary for files <= 65536 bytes long, so we no longer emit it for those. (issue #90)

ORG rework, part 3 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.

Allow explicit widths in project/platform symbols, part 3 Implement multi-byte project/platform symbols by filling out a table of addresses. Each symbol is "painted" into the table, replacing an existing entry if the new entry has higher priority. This allows us to handle overlapping entries, giving boosted priority to platform symbols that are defined in .sym65 files loaded later. The bounds on project/platform symbols are now rigidly defined. If the "nearby" feature is enabled, references to SYM-1 will be picked up, but we won't go hunting for SYM+1 unless the symbol is at least two bytes wide. The cost of adding a symbol to the symbol table is about the same, but we don't have a quick way to remove a symbol. Previously, if two platform symbols had the same value, the symbol with the alphabetically lowest label would win. Now, the symbol defined in the most-recently-loaded file wins. (If you define two symbols with the same value in the same file, it's still resolved alphabetically.) This allows the user to pick the winner by arranging the load order of the platform symbol files. Platform symbols now keep a reference to the file ident of the symbol file that defined them, so we can show the symbols's source in the Info panel. These changes altered the behavior of test 2008-address-changes, which includes some tests on external addresses that are close to labeled internal addresses. The previous behavior essentially treated user labels as being 3 bytes wide and extending outside the file bounds, which was mildly convenient on occasion but felt a little skanky. (We could do with a way to define external symbols relative to internal symbols, for things like the source address of code that gets relocated.) Also, re-enabled some unit tests. Also, added a bit of identifying stuff to CrashLog.txt.

Improve handling of C64 PRG header C64 PRG files are pretty common. Their salient feature is that they start with a 16-bit value that is used as the load address. The value is commonly generated by the assembler itself, rather than explicitly added to the source file. Not all assemblers know what a PRG file is, and some of them handle it in ways that are difficult to guarantee in SourceGen. ACME adds the 16-bit header when the output file name ends in ".prg", cc65 uses a modified config file, 64tass uses a different command-line option, and Merlin 32 has no idea what they are. This change adds PRG file detection and handling to the 64tass code generator. Doing so required making a few changes to the gen/asm interfaces, because we now need to have the generator pass additional flags to the assembler, and sometimes we need code generation to start somewhere other than offset zero. Overall the changes were pretty minor. The 20042-address-changes test needed a 6502-only variant. A new test (20040-address-changes) has been added and given a PRG header. As part of this change the 65816 variant was changed to use addresses in bank 2, which uncovered a code generation bug that this change also fixes. The 64tass --long-address flag doesn't appear to be necessary for files <= 65536 bytes long, so we no longer emit it for those. (issue #90)

Progress toward 64tass support Most tests pass, but 2007-labels-and-symbols fails because the expressions recognized by 64tass don't match up with either of the other assemblers.

Finish removal of "disable label localizer" feature The label localizer is now always on. The regression tests turned it off by default, but that's no longer allowed, so the generated output has changed for many of them. The tests themselves were not altered.

ORG rework, part 3 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.
