Yes:
```c
#include <arm_neon.h>

int8x16_t test_smax(int8x16_t a, int8x16_t b) { return vmaxq_s8(a, b); }
int16x8_t test_smin(int16x8_t a, int16x8_t b) { return vminq_s16(a, b); }
uint32x4_t test_umax(uint32x4_t a, uint32x4_t b) { return vmaxq_u32(a, b); }
uint8x8_t test_umin(uint8x8_t a, uint8x8_t b) { return vmin_u8(a, b); }
```
Compile with
```
./build/bin/clang -S -emit-llvm -Xclang -disable-llvm-passes neon_intrinsic_test.c -o -
```
You'll see the neon intrinsics.
