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: ; $a003
ds 2 ; dw Label
* Fix compatibility of rgblink -O and -t
The -t "tiny mode" option makes ROM0 cover 0x8000 bytes,
not 0x4000. The -O "overlay" option fills areas uncovered
by sections with data from an overlay file. These needed
to cooperate so that the calculated uncovered overlay size
does not exceed the actual size of the ROM.
Fixes#754
* Print link test names like asm tests do
* Make the three test.sh scripts more similar
This requires some special-casing for `jr @` because the `jr` opcode has
already been emitted, but not the operand, so PC points to the middle.
Moved the RGBLINK test to RGBASM's folder, and created a new RGBLINK test.
This allows whitespace between the brackets and the register.
This also fixes#531
Note that `$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.
This should help make RGBDS portable to systems with 16-bit integers,
like DOS.
For kicks, use the macros for 16-bit and 8-bit integers.
Fix other miscellaneous things, like #include ordering and other
printf-format related things.
Reduce repitition in math.c while I'm there.
The goal was to improve readability, but along the way a few things were
gained.
- Sorted sym and map files
- Infrastructure for supporting multiple .o versions
- Valgrind-proof, as far as my testing goes anyways
- Improved verbosity messages
- Added error checking
- Performance improvements, see end of commit message
The readability improvement was spurred while trying to make sense of the
old code while trying to implement features such as sorted sym and map
files.
I also did my best to remove hardcoded logic, such that modifications
should be doable; for example, "RAM loading" sections, which are linked
against a different location than the one they're stored at.
Some work remains to be done, see the "TODO:" and "FIXME:" comments.
Further, while regression tests pass, this new linker should be tested on
different codebases (ideally while instrumented with `make develop` and
under valgrind).
The few errors spotted in the man pages (alignment) need to be corrected.
Finally, documentation comments need to be written, I have written a lot of
them but not all.
This also provides a significant performance boost (benchmarked with a
51994-symbol project):
