Fix c4m_get_stack_bounds on Linux #18

Closed orangematt closed 3 months ago

orangematt commented 3 months ago

Fix c4m_get_stack_bounds for Linux. The original implementation incorrectly swaps bottom/top.

Move c4m_get_stack_bounds from gc.h to gc.c since there's no reason for it to be public at all, never mind static inline.

only called once per collection cycle
only called internally from gc.c
cost of pthread_getattr_np from the main thread is extremely high on Linux for both glibc and, to a lesser extent, musl.
