<pre>Inlining is disabled for functions with different sets of no_sanitize
attributes, because that could lead to either over- or under-sanitizing the
code, and it not clear which is better in general (and sometimes both are
wrong).
Apparently, always_inline attribute is stronger than that.
In the following example, f is inlined into g when build with -O3
-fsanitize=memory.
int sink;
__attribute__((always_inline, no_sanitize("memory")))
void f() {
sink = 1;
}
void g() {
f();
}</pre>
