This shortens the lexer by 100 lines and simplifies
access to expansion contents, since it usually needs the
deepest one, not the top-level one.
Fixes#813
This decoding required high lookahead, and was not even
consistently useful (the `garbage_char` test case was not
valid UTF-8 and so did not benefit from `reportGarbageChar`).
This limits UTF-8 handling to the `STRLEN` and `STRSUB`
built-in functions, and to charmap conversion.
Fixes the test case from #800
The `out.gb` output was corrected, since the two "test"
fragments have a different order in ROM than in SRAM.
It is effectively:
; ROM0[$0000], fragments ordered by size
jr Label
dw Label
db 0
; SRAM[$a000], fragments ordered by .o order
ds 1 ; db 0
ds 2 ; jr Label
Label: ; $a003
ds 2 ; dw Label
Explicit {interpolation} can still achieve this, but
to match DEF, REDEF, and PURGE, these new directives that
define symbols do not expand string EQUS.
We'll use "-rcX" instead of "-pre" to allow multiple ones, jic
Additionally, they will be able to be detected using __RGBDS_RC__
Finally, adapt everything version-related to this new system
This was removed in b3c0db218d
(along with two unrelated changes).
Removing this hack introduced issue #742, whereby INCLUDing
a file without a trailing newline can cause a syntax error.
A more proper fix would involve Bison's tracking locations,
but for now the EOF-newline hack fixes the issue while only
affecting some reported errors (expecting "newline"
instead of "end of file").
Fixes#742
* Mark `error` as a `format` function, to properly scan its format
* Fix the call to error() from parser.y:
- Use '%s' to avoid passing an arbitrary format
- Simplify yyerror overall
* Fix size parameter of %.*s format being an int... bonkers standard.
* Report the number of arguments required and provided on a STRFMT mismatch
* Add an assert to check for a very unlikely bug
This applies to macro arguments, DB, DW, DL, DS,
PRINT, PRINTLN, EXPORT, PURGE, and OPT.
It also removes support for empty entries in DB/DW/DL.
(Deprecating it would require keeping parser support,
which is ambiguous with trailing commas.)
Fixes#753
* Fix compatibility of rgblink -O and -t
The -t "tiny mode" option makes ROM0 cover 0x8000 bytes,
not 0x4000. The -O "overlay" option fills areas uncovered
by sections with data from an overlay file. These needed
to cooperate so that the calculated uncovered overlay size
does not exceed the actual size of the ROM.
Fixes#754
* Print link test names like asm tests do
* Make the three test.sh scripts more similar
In exponent(), 'base *= base;' should not run
when base is 65536, since it overflows an int32_t.
This also optimizes exponent() based on
gcc and clang -O3 test cases in godbolt.org.
