In software engineering , there is a concept : "Formal Technical Reviews" .

In my opinion , one of the best reviewers of a software is a compiler of its
language .
Having a second compiler in FreeBSD , will make it much better than the
present state .

My wish would be to pursue a language intersection of both CLang and GCC
compilers to be able to check their outputs .

If I could have sufficient power ( health , time , etc. ) , I even
want to try and make applicable one more compiler such as Portable C
Compiler ( which is available in ports ) .

Personally I am using two compilers ( Free Pascal and Delphi ) on a big
program , and I am obtaining very good results either as very useful
warnings or errors . In reality , to pursue such a multiple compiler usage
is really difficult , but end result is making efforts very fruitful .

I am using a similar technique for my Fortran programs . I can say that to
rely on a single compiler is not a very robust way of software development
after seeing quality of compiled programs : My policy is now "Never use a
single compiler without assuring that it is generating correct code when
compared to other compilers even though the current compiler is tested on
its test base ."  This is a result of so many combinations of  a language
usage that a test base can not cover but it may exist in a user program over
time .

This policy is developed by actual experiences .

Thank you very much .
