Try:

---
#include <stdint.h>

typedef uint32_t u32x4_t __attribute__ ((vector_size (16)));

void decode_and_jump(u32x4_t instructions) {
  void *ptr;
  asm("movd %[from], %k[to]\n" : [to] "=r" (ptr) : [from] "x" (instructions));
  goto *ptr;
}
---

Assembler will either accept "movd %xmm0,%rax" which is specified
by AMD or accept it as "movq %xmm0,%rax".
