- 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:/.
- Run-time dispatch is not forced in math libraries calls. The compiler can choose to call a CPU-specific version of a math function if one is available.
Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
