Vectorisation and SIMD are removed: these are straight scalar (element) ooerations. Vectorisation Context is provided by [[openpower/sv]]. +ternaryv is experimental and is the only operation that may be considered a "Packed SIMD". It is added as a variant of the already well-justified ternary operation (done in AVX512 as an immediate only) "because it looks fun". As it is based on the LUT4 concept it will allow accelerated emulation of FPGAs. Other vendors of ISAs are buying FPGA companies to achieve a similar objective. + # summary minor opcode allocation -- 2.30.2
