CLI back-end (work-in-progress)

[Roberto COSTA <roberto dot costa at st dot com>]

Hello,
some time ago I announced to gcc mailing list (see 
http://gcc.gnu.org/ml/gcc/2006-06/msg00420.html) the project of a CLI 
back-end. It aims at making gcc produce highly-optimized CIL binaries, 
compliant with ECMA specification 
(http://www.ecma-international.org/publications/standards/Ecma-335.htm).
The development is currently performed by a team of STMicroelectronics 
R&D division (which I belong to).

For those interested, here is a patch to get the current 
work-in-progress snapshot of the project.
The patch has been generated from r116473 of gcc svn repository.

In the current status, the back-end should be seen as a prototype. 
Several bugs are probably still hiding and it is not yet possible to 
build a full toolchain based on it.
Nevertheless, nearly all C99 features are already supported (complex 
numbers and variable-length arrays are the only I recall to be missing) 
and the number of unexpected failures in gcc testsuite is already quite low.

Don't hesitate to contact me for further details... or anything else!

Happy hacking,
Roberto
