Hi Alan,

For whatever reason in this simple example t3 is not being inlined, but I can set that aside for now. // t2.c: int t3();
Does inlining happen if you change this to:
int t3(void);
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.
