-Subject: [PATCH gnumach 2/2] kern: fix loop reading the time value
-
-Previously, recent versions of gcc would hoist the loads out of the
-loop reading the time value.
-
-* kern/macros.h (access_once): New macro.
-* kern/mach_clock.c (host_get_time): Use the new macro to prevent the
-loads from being hoisted out of the loop.
