- Subject: [PATCH] lldb: Link with libatomic on x86
- cmake atomic check is not sufficient for i686 target where clang14 still
- generates __atomic_store calls but the check does not entail this
- function and happily thinks that compiler can resolve all atomic via intrinsics
- on i686, but thats not the case, ideally the check for determining
- atomic operation should be make more robust but until then lets ask to
- link with libatomic on i686/linux
- Upstream-Status: Inappropriate [OE-Specific]
- Signed-off-by: Khem Raj <raj.khem@gmail.com>
