The table below lists all documented extended mnemonics for instructions:

Opcode Mnemonic Description Table Type
E750 VPOPCT Vector POPulation CounT Extended Mnemonics
E752 VCTZ Vector Count Trailing Zeros Extended Mnemonics
E753 VCLZ Vector Count Leading Zeros Extended Mnemonics
E75C VISTR Vector Isolate STRing Extended Mnemonics
E75F VSEG Vector Sign Extend to Grande Extended Mnemonics

Each extended mnemonic links to a text section with some additional info on the pertinent pseudo opcode.

Remark:
Please note that the creation of descriptions for all individual instructions is an ongoing process. As yet no such descriptions have been created for the opcodes on this page.

Extended Mnemonics for instructions in extension sets E750-E75F

All instructions in this table are six bytes in length. The first byte always has a value of X'E7', the second byte of the opcode is located in the sixth byte of the instruction and always has a value in the range X'50' through X'5F'.

    Tyrannosaurus Rex Dinos are not dead. They are alive and well and living in data centers all around you. They speak in tongues and work strange magics with computers. Beware the dino! And just in case you're waiting for the final demise of these dino's: remember that dinos ruled the world for 155-million years!
