While cleaning up xine-lib's code I found another interesting thing: send_ogg_buf | +24 # 3671 -> 3695, # inlines: 0 -> 1, size inlines: 0 -> 859 send_header | -116 # 7812 -> 7696, # inlines: 13 -> 1, size inlines: 6765 -> 418 I'm not sure if this is correct, but if the size of inlines increases so much and decreases so much, I'd expect the size of the function to follow suit..
