Attestation of operations by tool chains is described. An example of a storage medium includes instructions for receiving source code for processing of a secure workload of a tenant; selecting at least a first compute node to provide computation for the workload; processing the source code by an attestable tool chain to generate machine code for the first compute node, including performing one or more conversions of the source code by one or more convertors to generate converted code and generating an attestation associated with each code conversion, and receiving machine code for the first compute node and generating an attestation associated with the first compute node; and providing each of the attestations from the first stage and the second stage for verification.

Attestation of operations by tool chains

Detailed herein are systems, apparatuses, and methods for a computer architecture with instruction set support to mitigate against page fault- and/or cache-based side-channel attacks. In an embodiment, an apparatus includes a decoder to decode a first instruction, the first instruction having a first field for a first opcode that indicates that execution circuitry is to set a first flag in a first register that indicates a mode of operation that redirects program flow to an exception handler upon the occurrence of an event. The apparatus further includes execution circuitry to execute the decoded first instruction to set the first flag in the first register that indicates the mode of operation and to store an address of an exception handler in a second register.
