start writing code for decompressing chunk data.

I still haven't much of an idea where I'll take this, but it's a start. I know it is needed for block filtering and such, I still need to find a way how I'll actually implement it.
rework error.h, to decrease impact on binary size.

Quinn	7bdee8215f	start writing code for decompressing chunk data. I still haven't much of an idea where I'll take this, but it's a start. I know it is needed for block filtering and such, I still need to find a way how I'll actually implement it.	2025-09-09 16:30:40 +02:00
Quinn	fb52517f06	rework error.h, to decrease impact on binary size. We were statically creating a new string per log message, so re-using the same message would cause duplicate byte sizes. Now, all prefixes / suffixes are only defined once, the file name is defined once per file, the line number should be defined once per unique line. This just saves some memory in the final binary, allowing things to be optimised a little better.	2025-09-09 16:30:40 +02:00
Quinn	63df7430b7	fix: shouldn't multiply by `CHUNKS`, but by `SECTOR`	2025-09-04 13:28:13 +02:00
Quinn	527b1e2b16	change `mvchunks` parameter order, to be a bit more clear and consistent with functions such as `memmove`	2025-09-04 13:12:51 +02:00
Quinn	08ab721622	fix: violating strict aliasing rules in most areas in the new code. Yes, I am aware there are plenty of violations in `conf.c`, but I'll likely fix/rewrite those when I will use it. Since there are some other changes I think I'll want to make.	2025-09-04 13:12:51 +02:00
Quinn	0baa1ac9e8	add a flag when debugging to generate SIGFPE when signed integer overflow occurs. (this is UB)	2025-09-04 12:54:00 +02:00
Quinn	9cb0631df8	add comments to point at where strict aliasing rule violations occur in data scripts this is definitely not all of them, a thorough rewrite must take place to fix as many as we can.	2025-09-04 12:54:00 +02:00
Quinn	008604ff5e	delete redundant COLOUR32 definitions	2025-09-04 11:35:52 +02:00
Quinn	56427673cb	add `quit` in `main.c` to `atexit`, for added safety	2025-09-04 11:35:52 +02:00
Quinn	93db7681eb	write a portable version of `endian.h`, to replace the system's `endian.h`. utilising GNU C standard library for some of the functionality, or GNU C extensions.	2025-09-04 11:35:52 +02:00
