No, they're absolutely not. The restriction on not supporting exotic
platforms refers to the output. A compiler basically produces machine
code. If a C++ compiler for x86 is written in perfectly portable
C++, you could turn it trivially into a cross-compiler, but targetting
the PowerPC is non-trivial.

This is probably most relevant when it comes to exception-handling.
Quite a few important topics like register-handling are only relevant
when it comes to production-performance.

I don't think so.  There are projects like OpenC++ that are in the
same ballpark.  I think for most purposes a compiler that produced C
(or even C++) code would make a fine platform for such
experimentation.

It seems from various discussion that gcc is often considered as the
platform of choice to experiment with the C++ core language. I do not
think so.

Even if its GNU status make it really available, it is a production
compiler, and as such, it has to tackle many elements unnecessary for
experimentation. Several programming languages, a very wide range of
supported OS, a source code in C (I don't know why), a CVS process
designed for stability, an optimized compilation process...

So, here come my question : Does anyone have another contender ? What I
look for is :
- A compiler not micro optimised
- A compiler written in C++, and in "good" C++
- A compiler with source code available
- A compiler that does not care too much about exotic platforms (even if
at least two supported platform seems a minimum)


Does this compiler exist ?

Perhaps LLVM has something in common what you are looking for.

Perhaps having the source code in C makes it easier to bootstrap on unusu=
al
platforms?  In any case, I'd guess that C++ wasn't very stable when GCC w=
as
first developed.

Those two requirements are in conflict, as far as I'm concerned.
"good" C++  code produces correct results even on exotic platforms.
