Abstract: Techniques for an instruction for a Runtime Call operation are described. An example apparatus comprises decoder circuitry to decode a single instruction, the single instruction to include a field for an identifier of an opcode, the opcode to indicate execution circuitry is to execute a no operation when a runtime call destination equals a predetermined value; and execute an indirect call with the runtime call destination as a destination address when the runtime call destination does not equal the predetermined value. Other examples are described and claimed.

Abstract: Techniques for implementing instructions and modified instruction encodings for checking tags and for interspersing islands of tags in line with bucketed data for locality by a processor are described. In an example, an apparatus includes decoder circuitry and execution circuitry. The decoder circuitry is to decode an instruction into a decoded instruction. The instruction has an opcode to indicate that the execution circuitry is to use metadata and instruction encodings to selectively perform a memory safety check. The execution circuitry is to execute the decoded instruction according to the opcode.
