Explicit {interpolation} can still achieve this, but
to match DEF, REDEF, and PURGE, these new directives that
define symbols do not expand string EQUS.
Currently INCBIN gives an error if your start position == file size.
This means you cannot include an empty file.
It also means the text of the error message is incorrect
(as the start is not greater, but equal to the length of the file)
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
GitHub's ubuntu-18.04 environment installs gcc 7.3.0.
The latest ubuntu-20.04 environment installs gcc 9.3.0.
Version 9.3.0 is incompatible with building libpng 1.6.37,
as of 2021-03-04.
Fixes#783
* Store all the local symbols in object files, not only the ones that need linker patches.
This generates better map/sym files, and thus allows for better debugging as well.
* Add comments explaining the ->src and the (void)arg;
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
