Razvan Cojocaru	5a6d9b05b7	Bug 1786774 - Make the memory allocator spinlocks always spin in kernel-space on macOS/AArch64. r=gsvelto Differential Revision: https://phabricator.services.mozilla.com/D169067	2023-02-14 08:46:59 +00:00
Gabriele Svelto	44cbaf4248	Bug 1784018 - Remove deprecated OSSpinLocks r=glandium On macOS versions prior to 10.15 os_unfair_locks cannot spin in kernel-space which degrades performance significantly. To obviate for this we spin in user-space like OSSpinLock does, for the same number of times and invoking x86-specific pause instructions in-between the locking attempts to avoid starving a thread that might be running on the same physical core.
