< cap
| #define SIMDPP_HAS_UINT32_SHIFT_L_BY_VECTOR /* 1 if present, 0 otherwise */
|
||
Indicates support of efficient left per-element shift of uint32 vector data (see shift_l()). The macro evaluates to 1 if this operation is supported in the SIMD unit, 0 otherwise.
Currently, the macro is defined to 1 on all supported instruction sets.
