Assign deallocator hints to allocators #182

Open kees opened 2 years ago

kees commented 2 years ago

GCC 11+ has some analysis ability for checking for double-free, mismatched deallocators, etc.

Work to do:

[ ] Investigate needing to split __malloc from __alloc_size
[ ] Update __malloc (and __alloc_size) attributes to include a deallocator function name
[ ] Add deallocators to all __alloc_size (or __malloc)
[ ] Investigate needing to enable -fanalyzer in some way to gain warnings from new markings
[ ] Add support for deallocator marking to Clang: bug
