This option specifies whether to allow generation of a code using the division/multiplication and multiply-accumulate unit.
When the -cpu=S1 or -cpu=S3 option is specified, the code is the same as when the -use_mda=not_use option is specified.
When the -cpu=S2 option is specified, the code is the same as when the -use_mda=mda option is specified.
This option specifies whether to allow generation of a code by the compiler using the division/multiplication and multiply-accumulate unit. |
To control codes other than those generated by the compiler, isolation of the runtime library is also required. For details, see "7.1 Supplied Libraries". |
Do not specify -use_mda=mda for devices without division/multiplication and multiply-accumulate units. |
To generate a code that uses the division/multiplication and multiply-accumulate unit, describe as: |
