Justine Tunney	59692b0882	Make spinlocks faster (take two) ... This change is green on x86 and arm test fleet.	2024-07-26 00:45:24 -07:00
Justine Tunney	86d884cce2	Get rid of .internal.h convention in LIBC_INTRIN	2024-07-19 19:38:00 -07:00
Justine Tunney	9b6718ac99	Improve backtraces ... We're now able to rewind the instruction pointer in x86 backtraces. This helps ensure addr2line cannot print information about unrelated adjacent code. I've restored -fno-schedule-insns2 in most cases because it really does cause unpredictable breakage for backtraces.	2024-05-30 15:23:11 -07:00
