Pretty good news! CLang now compares well with GCC.
The CLang and underlying LLVM projects use liberal BSD, NCSA and MIT licenses compatible with the Apache 2.0 license (see ). That's better than GCC, GPL licensed and usable to build an Apache project but not embeddable in the project itself.
I've been thinking about using CLang in the Apache Tuscany C++ project for a while.
I'd like to use its API to convert SCA composites (XML docs describing SCA component assemblies) into C++0x templates and compile them into machine code on the fly, instead of having to interpret all the XML gorp at run-time.
Think of it like an 'SCA assembly JIT compiler'...
Benefits: ultimate speed, CPU and space, cloud resources (and resulting monthly bill) optimizations, and less XML parsing and interpretation code to worry about.
Requirement: support for C++0x variadic templates...
Patience may pay off after all, as it is finally there.
I gotta try that stuff this weekend!
