 **Description**:
 
-The ``__builtin_cpu_supports`` function detects at runtime if the target CPU
-supports features specified in string argument. It returns a positive integer
-if all features are supported and 0 otherwise. Names of features and format are
-target specific. For example on AArch64 features are combined using ``+`` like
-this ``__builtin_cpu_supports("flagm+sha3+lse+rcpc2+fcma+memtag+bti+sme2")``.
-If a feature name is not supported or the format is wrong, the compiler will issue a
-warning and replace builtin by the constant 0.
