--- Comment #8 from Jonathan Gray <j...@openbsd.org> --- There is no way to backport builtins for architectures that lack atomics at the ISA level. On arm/hppa/sh linux has a syscall which the gcc documentation claims can only do 64 bit values on arm: https://gcc.gnu.org/wiki/Atomic Even on Linux with the latest toolchains this should be checked as there are cases where some or none of the atomics may be present. -- You are receiving this mail because: You are the QA Contact for the bug.
