ISSOtm b1cd730db2 Add link-time RST instruction 
This allows using a label as the argument to a `rst` instruction
Fixes rednex#448

ISSOtm 359a048b6e Bump object version number 
We're about to break the format, so let's do this
 2020-02-03 21:07:12 +01:00
ISSOtm f2be601a13 Check "left" boundary as well in isLocationSuitable 
"fixed" and "aligned" location checking advanced the target location to places
regardless of the associated free space, potentially breaking the assumption
that the location was always further in memory than the free space's base.

Rather than adding more code to try keeping that assumption true, harden
`isLocationSuitable` and handle that case as well.

 2020-02-03 03:49:38 +01:00
ISSOtm b16ec83a33 Add gbdiff.bash script 
This script allows diffing two Game Boy ROMs using `xxd` and `diff` and
attempts to augment the diff using information pulled from SYM files.
It's not part of RGBDS proper, but can be useful to debug tests (when ROMs fail
to match).
 2020-01-30 02:43:31 +01:00
ISSOtm ed72baca2a Make more symbol functions const 
Can't hurt to specify those as they are now. Perhaps it'll enable slightly more
compiler optimizations, too?

ISSOtm e2e01e84fa Fall back from failure in time a bit better 2020-01-30 02:07:55 +01:00
ISSOtm 93ee417567 Fix timestamp symbols on Windows (partially) 
Windows does not honor `%F` nor `%T` in `strftime`. These are worked around
by writing the full format they serve as a short for.
However, Windows also treats `%z` and `%Z` identically, where SUS instead
requires `%z` to output a ±XXXX offset.
Since the current information is broken (no information), this isn't *breaking*
anything, but at least provides something a human will probably understand.
`__ISO_8601_UTC__` is unaffected because it hardcodes the timezone character,
only `__ISO_8601_LOCAL__` suffers from this.

It should behave identically to both of these on separate lines

 2020-01-28 18:59:11 +01:00
ISSOtm b11d121c48 Remove undefined behavior from shifts 
`asl` and `asr` in `src/link/patch.c` courtesy of @pinobatch, and rearranged in RGBASM
evaluators.
 2020-01-28 12:37:38 +01:00
ISSOtm cdf6000618 Report failing file names in comparisons 
The files being diffed (especially for  variants) are temp files, so their
names are pretty nondescript. This improve error output, using ANSI escape
sequences to make those lines stand out.
 2020-01-28 11:44:50 +01:00
ISSOtm 1bd41bf79a Don't use diff to compare bin files in tests 2020-01-26 21:10:31 +01:00

ISSOtm 6fc5097278 Allow outputting dep files to stdout using - 2020-01-26 15:33:36 +01:00
ISSOtm 12f2f654dd Add -MG 
This option allows for automatic dependency detection and generation:
as soon as a missing file is found, it is output to the dep file, and
assembly immediately aborts. (No .o file is produced, even if `-o` was
speicified.) This doesn't cause an error, either; the point is that once
the file is added to the dep file, the Makefile is re-parsed, and this
time the file will be generated, so the dep list builds up automatically.
This mimicks GCC's option and behavior.
 2020-01-26 15:33:36 +01:00
ISSOtm 0649b360fb Allow specifying multiple dependency targets 
This is done to match GCC's behavior.
Also, this unifies the code of -MT and -MQ.
 2020-01-26 15:32:45 +01:00
ISSOtm f1f314270d Add -MQ 
Just like GCC's -MQ, this is basically -MT but the file name is escaped.
 2020-01-26 15:32:45 +01:00
ISSOtm 1fb9f90f0f Add -MT option 
Allows overriding the output file in dependencies, which also allows
outputting those without also outputting the object file.
This, again, mimicks GCC's option.
 2020-01-26 15:32:45 +01:00
ISSOtm bfa8da78a6 Add -MP option 
Adds a phony target to every included file, mimicking gcc's

ISSOtm ab9307ac61 Clean up symbol management 
Stop using that bitfield for everything, including what can be determined otherwise
It also makes it easier to have a sane state, since some bits were (supposedly)
mutually exclusive
 2020-01-24 02:51:48 +01:00
ISSOtm e3ef194b4f Remove local label error checking 
This is actually not necessary, because RGBLINK would warn about missing labels.
Besides, through semi-esoteric ways, it is possible to define more labels in this scope,
and there's no reason to prevent that.

 2020-01-19 11:02:47 +01:00
ISSOtm 50f091ab7c Fix RGBLINK failing to read args on certain machines 
`char` has implementation-defined signedness, and if it's chosen to be unsigned,
then -1 gets converted to 255, which is then promoted back to `int` as... 255,
always failing the loop condition in src/link/main.c:118
`int8_t` has the correct signedness, but considering `musl_getopt_long_only`
returns `int`, better use that so as not to lose any bits

Closes #462, although with this implementation `BANK("some ROMX section")` would

ISSOtm 5a06fad31e Separate stdout and stderr in tests 
POSIX leaves undefined the order of output if stderr is injected into stdout,
and in practice it differs on Windows (Linux buffers both streams separately,
Windows interleaves them as they arrive without buffering).
This should help testing on other platforms
