Arguments
None
Default
-no-simd-function-pointers
or
/Qsimd-function-pointers-
Pointers to simd-enabled functions are disabled. Vector specifications can only be placed in function declarations and definitions.
Description
This option enables or disables pointers to simd-enabled functions.
When option
[Q]simd-function-pointers
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.
Alternate Options
None
