This instruction is a mixed-type instruction.
The disassembler can generate
lookup instructions when disassembling a node of a multinode model with positive length of look-ahead signal segment.
qsmm_desc_s structure passed to the function
qsmm_create specifies this length when creating the multinode model.
qsmm_get_ngram_env_la_sz fetches this length for an existing multinode model.
The instruction has the syntax
and sets the outcome equal to a look-ahead signal at zero-based position in the look-ahead signal segment.
The assembler does not support loading assembler programs into the nodes of a multinode model with positive length of look-ahead signal segment.
Therefore, if you need to assemble a program (e.g. generated by the disassembler) containing
lookup instructions, you do the following:
