When compiling with -Winline -O[2,3,s], I frequently get errors like:
mistream.h:196: warning: called from here
mistream.h:174: warning: inlining failed in call to 'bool
ustl::istream::aligned(size_t) const': --param large-function-growth limit
reached
This is understandable, since I use a lot of inlining and inevitably run over
this limit or one of the others. Explicitly increasing the --param value solves
the problem.
However, it bothers me that the compiler requires special flags to inline
functions that I have already explicitly declared as inline. When I use the
inline keyword in a declaration, I expect the compiler to inline it no matter
what, with debug builds being the only exception.
So can the optimizer automatically adjust inlining parameters and inline
everything I tell it to inline? I suppose it might be a bit of work, since
explicit parameter limits should still be honored.
