The table below lists all documented extended mnemonics for instructions:

Opcode	Mnemonic	Description	Table Type
E780	VFEE	Vector Find Element Equal	Extended Mnemonics
E781	VFENE	Vector Find Element Not Equal	Extended Mnemonics
E782	VFAE	Vector Find Any element Equal	Extended Mnemonics
E78A	VSTRC	Vector STRing range Compare	Extended Mnemonics

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

Opcode Assignments.

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 E780-E78F

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'80' through X'8F'.
