Justine Tunney	098638cc6c	Fix pthread_kill_test flake on qemu	2024-08-16 21:18:26 -07:00
Justine Tunney	11d9fb521d	Make atomics faster on aarch64 ... This change implements the compiler runtime for ARM v8.1 ISE atomics and gets rid of the mandatory -mno-outline-atomics flag. It can dramatically speed things up, on newer ARM CPUs, as indicated by the changed lines in test/libc/thread/footek_test.c. In llamafile dispatching on hwcap atomic also shaved microseconds off synchronization barriers.	2024-08-16 11:14:46 -07:00
Justine Tunney	e398f3887c	Make more improvements to threads and mappings ... - NetBSD should now have faster synchronization - POSIX barriers may now be shared across processes - An edge case with memory map tracking has been fixed - Grand Central Dispatch is no longer used on MacOS ARM64 - POSIX mutexes in normal mode now use futexes across processes	2024-07-24 01:19:54 -07:00
