Inlining of guards is important for optimizing. Consider
int flag;
int foo (void)
{
if (!flag)
return 0;
...
}
we should be able to partially inline foo into its callers transforming
if (foo ())
{
...
}
else
{
...
}
to
if (!flag)
<ret> = 0;
else
<ret> = foo.clone();
if (<ret>)
{
...
}
else
{
...
}
to be able to perform optimizations across the path where foo.clone
is not executed.
