Does `-finline-limit=1200' (or bigger) help? I think GCC 3.3 added a warning for when inline functions generated `a lot' of instructions. In such a case, the function is not inlined. I believe this also happened with GCC 3.2, but it just didn't normally tell you about it. Cheers, -- Jacques Vidrine . NTT/Verio SME . FreeBSD UNIX . Heimdal [EMAIL PROTECTED] . [EMAIL PROTECTED] .
