Fixes #1054. Previously, bit-fields followed by another field were aligned to two bytes. Bit-fields ending the struct were (and continue to be) aligned only to a single byte. ``` struct s { unsigned int x : 4; }; struct t { unsigned int x : 4; unsigned int y; }; ``` Before: `sizeof(struct s) == 1`, sizeof(struct t) == 4` After: `sizeof(struct s) == 1` sizeof(struct t) == 3`
cc65 is a complete cross development package for 65(C)02 systems, including a powerful macro assembler, a C compiler, linker, librarian and several other tools.
cc65 has C and runtime library support for many of the old 6502 machines, including
- the following Commodore machines:
- VIC20
- C16/C116 and Plus/4
- C64
- C128
- CBM 510 (aka P500)
- the 600/700 family
- newer PET machines (not 2001).
- the Apple ][+ and successors.
- the Atari 8-bit machines.
- the Atari 2600 console.
- the Atari 5200 console.
- GEOS for the C64, C128 and Apple //e.
- the Bit Corporation Gamate console.
- the NEC PC-Engine (aka TurboGrafx-16) console.
- the Nintendo Entertainment System (NES) console.
- the Watara Supervision console.
- the VTech Creativision console.
- the Oric Atmos.
- the Oric Telestrat.
- the Lynx console.
- the Ohio Scientific Challenger 1P.
The libraries are fairly portable, so creating a version for other 6502s shouldn't be too much work.
