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.
Fixes#683 and #691
The lexer's raw mode for reading macro args already attempted
to handle semicolons inside string literals, versus outside ones
which start comments. This change reuses the same function for
reading string literals in normal and raw modes, also handling:
- Commas in strings versus between macro args
- Character escapes
- {Interpolations} and \1-\9 args inside vs. outside strings
- Multi-line string literals
Macro args now allow escaping '\', '"', and '\\'.
A consistent model for expanding macro args and interpolations,
within macro args, string literals, and normal context:
- "{S}" should always equal the contents of S
- "\1" should always act like quoting the value of \1
In preparation for an upcoming change
Makes for nicer error messages, complaining about EOF instead of newlines
The hack had to be kept for the lexer raw mode to avoid a bug;
see the relevant code comment for more info.
- Make it work inside pipelines
- Add RGBFIX tests to the suite
- Be more flexible in accepted MBC names
- Add warnings for dangerous or nonsensical input params
- Improve man page
This is not used in all bison versions, which causes a
"defined but not used" warning for the 'rgbasm_yytnamerr'
replacement, treated as an error by 'make develop'.
