Merging identical functions in GCC

[Michael Popov]

Hello!

There is very good blog post about the problem:

Will GCC support this feature?
It might be very useful in some cases, reduce code size and locality.


Some info about possible problems can be found here:

So, due to incompatibilities with debugging and C/C++ standards
this feature should be optional and disabled by default.


Best regards,
Michael
