#include <stdio.h>
#include <lsxintrin.h>
#define BS_VEC(type, num) type __attribute__((vector_size(num * sizeof(type))))
int main ()
{
BS_VEC(long int, 2) BS_VAR_0[1] = {};
BS_VEC (unsigned int, 4) tt = (BS_VEC(unsigned int, 4))
__lsx_vadd_w((__m128i){2655507415, 0, 0, 0}, (__m128i){});
BS_VEC(unsigned int, 2) SHUF = __builtin_shufflevector(tt, (BS_VEC(unsigned
int, 4)){}, 0, 1);
BS_VAR_0[0] = __builtin_convertvector(SHUF, BS_VEC(long int, 2));
printf("res[0] is 0x%016llx\n", BS_VAR_0[0][0], BS_VAR_0[0][1]);
}
This small test case can reproduce the problem above.
