The expectation that these extensions not be supported by upstream tool-chains is something with which we wholeheartedly agree. The problem is that our Bit-Manipulation Extension alone, needed for Audio/Video and Cryptographic workloads, struggles to fit into that space, and we have not yet added Custom 3D opcodes or the IEEE754 Transcendentals (SIN, COS). -- 2.30.2
