Does inlining happen if you change this to:<br>
<br>
int t3(<b>void</b>);<br>
<br>
Without the void, it's a non-prototype declaration (a pre-ANSI C
holdover) and will get compiled to "declare void t3(...)". I'm
guessing you'll see a bitcast at the call site which the inliner
can't look through.<br>
