Document the existing `ROUND`, `CEIL`, and `FLOOR` functions
Also update the trig function docs for searchability
Implement `POW` and `LOG`
Addresses part of #675
Implement ** for integer exponents
** has higher precedence than -, like Python, so -3**4 == -(3**4) == 81
The old "find symbol with auto scope" function is now three:
- One finds the exact name passed to it, skipping any checks
This is useful e.g. if such checks were already performed.
- One checks that the name is not scoped, and calls the first.
This is useful for names that cannot be scoped, such as checking for EQUS.
Doing this instead of the third should improve performance somehwat, since
this specific case is hit by the lexer each time an identifier is read.
- The last one checks if the name should be expanded (`.loc` → `Glob.loc`),
and that the local part is not scoped. This is essentially the old function.
Use C11 standard _Noreturn instead of attributes (except, of course, MSVC)
Remove unused helpers
Avoid trapping in release builds, in favor of just unreachability
Improve shim when __builtin_* are not available
Build type no longer defaults to Release (!)
have separate options for extra warning flags and sanitizers
toss DEVELOP macro
Fix sanitizers with CMake while I'm at it :|
They were expanded during the capture, and there was no easy way to
avoid expanding them (believe me, after three hours and somehow an OOM, I
gave up trying).
Add keywords and identifiers
Add comments
Add number literals
Add strings
Add a lot of new tokens
Add (and clean up) IF etc.
Improve reporting of unexpected chars / garbage bytes
Fix bug with and improved error messages when failing to open file
Add verbose-level messages about how files are opened
Enforce that files finish with a newline
Fix chars returned not being cast to unsigned char (may conflict w/ EOF)
Return null path when no file is open, rather than crash
Unify and improve error printing slightly
Known to be missing: macro expansion, REPT blocks, EQUS expansions
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.
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
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
