Unfortunately not. In -025 they've removed most of the instructions from the manual (moved to another manual), so e.g. -028 is useless for anything except the very latest ISAs. So when talking about VL,BW,DQ at least, all those are in the base manuals now. Jakub

Hmm, this is not good since 319433-020.pdf and 319433-022.pdf redirect to 319433-028 (which is the same as under the new URL I now used). And the links to 319433-015.pdf and 319433-023.pdf both were broken. Do you have a recommendation? Gerald

I think https://software.intel.com/sites/default/files/managed/39/c5/325462-sdm-vol-1-2abcd-3abcd.pdf The -028 manual only contains AVX512{VBMI,IFMA,4FMAPS,4VNNIW,VPOPCNT*} instructions plus for some very strange reason VPERMT2* instruction which is declared to be part of AVX512{F,VL,BW}.
