Is an optional list of one or more math library functions to which the attribute should be applied. If you specify more than one function, they must be separated with commas.

Precision-specific variants like sin and sinf are considered different functions, so you would need to use

-fimf-dynamic-target=sin,sinf

(or

/Qimf-dynamic-target:sin,sinf

) to specify run-time dispatch for both the single-precision and double-precision sine functions.

You also can specify the symbol /f to denote single-precision divides, symbol / to denote double-precision divides, symbol /l to denote extended-precision divides, and symbol /q to denote quad-precision divides. For example, you can specify

-fimf-dynamic-target=/

or

/Qimf-dynamic-target:/

.
