__builtin_mma_xxmfacc

Purpose

Moves to accumulator.

The contents of the accumulator represented by a are copied into the four vector registers represented by a.

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 de-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.
