@RichFelker @ch3root @spun_off which non-2's complement platforms does musl support?
@BRIAN_____ @johnregehr @ch3root @spun_off No. Without that you can still do all sorts of math treating the values as opaque.

@BRIAN_____@johnregehr@ch3root @spun_off Hashing or encryption of ptrs, xor linked lists, 'base-relative' diffs for ptrs in shm, etc. -
@RichFelker@johnregehr@ch3root @spun_off The standard says only that given a uintptr_t converted from pointer, you can recover pointer. -
@BRIAN_____@johnregehr@ch3root @spun_off Yes. But you need to understand "a uintptr_t converted from a pointer" is a _value_. -
@BRIAN_____@johnregehr@ch3root @spun_off You can recover the ptr as long as you have that value. Ways of keeping the value are limitless.
