+ The `cir.cpuid` operation retrieves different types of CPU information and
+ stores it in an array of 4 integers.
+
+ This operation takes 3 arguments: `cpu_info`, a pointer to an array of 4
+ integers; `function_id`, an integer determining what type of information to
+ be retrieved (for instance, basic information, processor information and
+ features, or cache/TLB information); and `sub_function_id`, an integer that
+ adds more detail about what information is requested.
+
+ As a result, the array of 4 integers is filled with the requested
+ information.
+
+ Example:
+
+ ```mlir
+ cir.cpuid %cpui_info, %function_id, %sub_function_id : (!cir.ptr<!s32i>,
+ !s32i, !s32i)
+ ```
+ }];

+ (ins Arg<CIR_PtrToType<CIR_SInt32>, "array address",

+ CIR_SInt32:$sub_function_id);
+
+ let assemblyFormat = [{
+ $cpu_info`,` $function_id`,` $sub_function_id `:`
+ qualified(type($cpu_info)) `,`
+ type($function_id) `,`
+ type($sub_function_id) attr-dict
