|
|
Whenever possible, statements with no effect are discarded. But
|
|
if they are nested within another construct which cannot be
|
|
discarded for some reason, they are instead replaced with an
|
|
empty statement, generated by <code>build_empty_stmt</code>.
|
|
Initially, all empty statements were shared, after the pattern of
|
|
the Java front end, but this caused a lot of trouble in practice.
|
|
|
|
<p>An empty statement is represented as <code>(void)0</code>.
