2018-07-31Add __builtin_speculation_safe_valueRichard Earnshaw1-0/+2
This patch defines a new intrinsic function __builtin_speculation_safe_value. A generic default implementation is defined which will attempt to use the backend pattern "speculation_safe_barrier". If this pattern is not defined, or if it is not available, then the compiler will emit a warning, but compilation will continue. Note that the test spec-barrier-1.c will currently fail on all targets. This is deliberate, the failure will go away when appropriate action is taken for each target backend. gcc: * builtin-types.def (BT_FN_PTR_PTR_VAR): New function type.
