This requires some special-casing for `jr @` because the `jr` opcode has
already been emitted, but not the operand, so PC points to the middle.
Moved the RGBLINK test to RGBASM's folder, and created a new RGBLINK test.
The code expected to never get "known" expressions passed in, as RGBASM
otherwise patches the bytes in by itself; however, JR cannot be patched in
by RGBASM unless the section's base address is known as well!
This allows whitespace between the brackets and the register.
This also fixes#531
Note that `$ff00 + c` is still treated as a single token, because trying to
use an expression on the left side causes a shift/reduce conflict.
This isn't great, but most people seem to be either used to it as-is, or
using the new `ldh a, [c]` syntax.
If this causes problems with a lexer rewrite, it'll be deprecated; but for
now, keep it around, as the support is clunky but bearable.
Create a new file, platform.h, for platform-specific hacks
for MSVC, this includes defining strncasecmp to _stricmp and
strdup to _strdup, among other things like defining missing
stat macros
Change some things not supported in MSVC, like _Static_assert,
to their counterparts (in this case, static_assert)
Replace usage of VLAs with malloc and free
Update getopt_long and use the getopt implementation from musl
on Windows.
Use comments to show which functions from platform.h are being used
While compiling for empscripten there is a duplicate symbol conflict with these two variables. And as they are only used locally, and do not need a symbol exported they can just be static.
This should hopefully work torwards compatibility with more systems.
I've tried to make this as general as possible but some small assumptions
about the compiler are made. I've also tried to recreate the build process
as closely as possible, but I had to change some things slightly to work
with CMake (version strings, mainly).
For now, it doesn't allow in-source builds, as that could overwrite the
Makefile.
This adds:
- Support for more build systems
- Automatic dependency generation
- Performance gains (especially when using i.e. Ninja)
Defaults to Release build.
This one's really stupid; printing an int with %hhu gives a warning
even though a regular unsigned char is promoted to an int before
printing anyway. Silence it so the build with Clang works.
This is a regression introduced in 5c24de3
GCC with the -std=c11 defines __STRICT_ANSI__. DJGPP checks if
__STRICT_ANSI__ is defined and if so doesn't define some things
mandated by POSIX such as struct stat, PATH_MAX, and others.
The -std=gnu11 option does not define this macro, so use it instead.
_DEFAULT_SOURCE isn't needed as no GNU nor BSD-specific functions
are used. Remove it.
Fix the last two occurrences of incorrect format specifiers for standard
fixed-width integer types.
