__m256i __lasx_xvslei_bu (__m256i a, imm0_31 imm)

Synopsis

__m256i __lasx_xvslei_bu (__m256i a, imm0_31 imm)
#include <lasxintrin.h>
Instruction: xvslei.bu xr, xr, imm
CPU Flags: LASX

Description

Compare the unsigned 8-bit elements in a and b, store all-ones to dst if corresponding element in a is less than or equal b, zero otherwise.

Operation

for (int i = 0; i < 32; i++) {
  dst.byte[i] = ((u8)a.byte[i] <= imm) ? 0xFF : 0;
}

Tested on real machine.
