__builtin_mma_xxmtacc

Purpose

Moves to accumulator.

The contents of the four vector registers represented by a are copied into the ACC accumulator.
Note: This built-in function is valid only when both of the following conditions are met:
  • The -mcpu option is set to target Power10 processors.
  • The compiler mode is 64-bit.
Note: This built-in function is provided to insert accumulator prime operation as needed. It should be avoided as the compiler inserts the minimal necessary operations in all known cases. Using it results in redundant operations.
