<pre>
    The "cold" attribute suppresses function alignment if I compile with optimization.
```
$ cat t.cpp
#ifdef BAD
#define COLD __attribute__((cold))
#else
#define COLD
#endif
COLD int a() { return 1; }
$ clang -S t.cpp -o - -O1 | grep p2align
        .p2align 4, 0x90
$ clang -S t.cpp -o - -O0 | grep p2align
        .p2align 4, 0x90
$ clang -S t.cpp -o - -O1 -DBAD | grep p2align
