Sure Yonghong, I can include that in this PR. Similarly, since we cannot have
both `relaxed_load<atomic_load_zext_{8,16}>` and
`relaxed_load<atomic_load_sext_{8,16}>`, I'll keep it `zext` (`BPF_MEM` |
`BPF_LDX`) for now. For example:
```c
int foo(char *ptr) {
return __atomic_load_n(ptr, __ATOMIC_RELAXED);
}
```
This'll be compiled into:
```
0000000000000000 <foo>:
0: 71 11 00 00 00 00 00 00 w1 = *(u8 *)(r1 + 0x0)
1: bc 10 08 00 00 00 00 00 w0 = (s8)w1
2: 95 00 00 00 00 00 00 00 exit
```
