Xavier Del Campo Romero 8a2647469b Makefile.cfg: select PSXSDK_PATH if defined 2021-10-24 03:10:57 +02:00
Xavier Del Campo Romero 573e4c150b Fix vprintf(3) 
TODO: what did this actually fix?
 2021-10-24 03:10:03 +02:00
Xavier Del Campo Romero a34280dec7 Provide buffered fread(3) 
In order to reduce calls to seek(2) (which are very expensive), this
commit keeps a sector-sized cache for each available FILE instance,
except from the standard streams, of course.

As expected, this allows calls to fread(3) to react much faster when
small, contiguous chunks are read.

Xavier Del Campo Romero 9c6112eb5b fopen_internal: return ENOENT on file not found 
This is actually expected by open(2), but I do not expect the BIOS
implementation to conform.

Xavier Del Campo Romero 58256c917e fopen_internal: do not resolve cdromL by default 
This avoids calling malloc(3) and thus allowing the linker to remove
the heap implementation from memory.c via --gc-sections.

Xavier Del Campo Romero d3780c0d7d Fix buffer overflow on GsLoadFont 
LoadImage accesses img[0..15] when w=16, h=1, causing it to read past `pal`.

Xavier Del Campo Romero 89b059cace Allocate .sbss and .common into .bss 
GNU ld fragments .bss into .sbss and .common (see man nm(1) for further
reference). However, the linker script used by PSXSDK did not determine where
to put such sections, causing some statically allocated objects to be placed
**after** __bss_end, leading to undefined behaviour.
