simd-function-pointers, Qsimd-function-pointers

Enables or disables pointers to simd-enabled functions.


Linux and macOS:
Pointers to simd-enabled functions are disabled. Vector specifications can only be placed in function declarations and definitions.
This option enables or disables pointers to simd-enabled functions.
When option
is specified, it defines simd-enabled (vector) function pointers by placing vector specifications with all usual clauses in function pointer declarations. The vector specifications must be indicated in an attribute vector declaration or in pragma
omp declare simd
These pointers can enable indirect calls to appropriate vector versions of the function from a simd loop or another simd-enabled function.

Product and Performance Information


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.
