Chrome disables these for speed and code size, so we need
to disable them to make sure our code is safe when used
this way.
int foo() {
static int32_t atomic_thing;
return sk_atomic_inc(&atomic_thing);
}
is not safe in Chrome. Making the static global is:
static int32_t atomic_thing;
int foo() {
return sk_atomic_inc(&atomic_thing);
}
