For the testcase in this message, I get (I removed the always_inline) all wrappers inlined to bloatit. Of course bloatit does not get inlined w/o always_inline - it's a huge function and not a simple wrapper. With always_inline on it, the wrappers are no longer inlined - this is a bug and should be reported. Of course from 4.1.0 on you can easier stick an __attribute__((flatten)) on the function you want everything inlined to (finalblow) and get everything inlined into it. Can you report a bugzilla for the bad interaction between always_inline and inlining of simple wrappers? Thanks, Richard.
