inline bug (?)

[jorge.perez@invia.fr]

Thans for your comments guys, I'll follow your suggestions and try other examples and test additional options as well. 

I forgot to precise however that I used the option -os (optimizing for size)

Regards


Jorge

If you are not happy with the way gcc inlines "by default", you can
influence the inlining heuristics by many parameters / compile options,
like: large-function-insns, large-function-growth,
inline-unit-growth,...
There is a long list in the manpage ;-)
