still not read my mail where i actually compared it in real. or don't 
want?

I really don't care about cool graphs but at facts for me as a USER (not 
developer) of C compiler.

And the facts are: Lots of worktime were spent to make new C compiler from 
scratch and this resulted with thing 5 times larger, working at similar 
speed and producing similar code to GCC that is already considered bloat.

Not something to be proud about.

That's truth. and truth is the only thing i do care about. I leave hype 
and propaganda and cool graphic bars that shows a really not important
part of C compiler performance - code parsing and generating unoptimized 
code (-O0).

The truth is sad. Starting from fresh and not being able to beat 25-year 
old bloated gcc is just funny.


That's my view - as a final "consumer", not developer. My view is that 
bloatware is replaced by another bloatware, which - because of it's young 
age - have greater future potential of bloat than GCC.


This tens or hundreds of thousands of work-hours could be spent far better 
by getting latest gcc available on GPLv2 licence and start from there, 
just improving it.

GNU communist licence for C compiler is not bad at all (contrary to other 
software).
