A conservative mark-and-sweep garbage collector implementation in C on x86 and x64. This implementation implements its own heap & allocator, conservative scanning of the program stack as well as the CPU registers, and recursive scanning of referenced blocks. Note that this is just a hobby project; this is not necessarily production-suitable. Like with any conservative garbage collector implementation, it's not able to scan for misaligned pointers or malformed pointers (for example, by using the XOR pointer trick in linked lists). Run build.sh on Linux or Mac, or build.bat on Windows, in order to test the example.c program.

Further documentation is available through docstring comments in ccgc.h.

• ccgc_malloc - allocates GC heap memory
• ccgc_free - frees GC heap memory
• ccgc_collect - collects and frees unreachable blocks
• ccgc_desegment - desegments/merges consecutive free blocks in the GC heap
• ccgc_resetPage - resets GC heap with zeroes, removing every block in the heap
• ccgc_dumpPage - prints every block in the GC heap, with its use-status, size, and content
