optimizing static inline recursive functions

[Reza Roboubi]

I believe gcc treats all function calls as fairly sacred and doesn't 
really optimize across function calls much.  For example, the 
pcre(regex) library creates it's own stack frames and "simulates" the 
entire function recursion to overcome this (and I think it has to, 
otherwise big inefficiencies would result.)

Are there plans to add this feature to gcc?
Thanks a lot.
