[Development] Qt binaries with inlined functions

[Dimitar Dobrev]

Thiago, thank you very much for these explanations. About that option, it only works on Windows so it's no good either way.

About generating wrappers for inlines, if you know of a tool that can do that - as I mentioned earlier - it would be of great help to me.

Here's also why we can't use -fkeep-inline-functions:

$ cat main.cpp
#include <utility>                        
#include <algorithm>
#include <vector>

$ g++ -O3 -S -o - main.cpp
        .file   ""
        .ident  "GCC: (SUSE Linux) 4.8.1 20130909 [gcc-4_8-branch revision 
202388]"
        .section        .note.GNU-stack,"", at progbits

$ g++ -O3 -fkeep-inline-functions -S -o - main.cpp | wc -l
2086

This would keep every single, minor and helper inline function from the 
Standard Library. We can't do that.

On Windows, however, we could use the -fkeep-inline-dllexport, which would 
make GCC match MSVC behaviour, at the cost of bloating the libraries with code 
that is never called. I'd rather we didn't do it.
