According to the latest documentation I have the ACLE prototypes for
float16_t vget_lane_f16(float16x4_t v, const int lane)
float16_t vgetq_lane_f16(float16x8_t v, const int lane)
float16x4_t vset_lane_f16(float16_t a, float16x4_t v, const int lane)
float16x8_t vsetq_lane_f16(float16_t a, float16x8_t v, const int lane)
Perhaps, I'm misunderstanding your or you're using outdated documentation?
