Clang was built by Apple, because they were getting impatient with GCC's (lack of) support of Objective C/Objective C++. (GNU rates ObjC as 'low priority').

So apple funded a project to supercede GCC, which was for C-family LANGuages.

The main points are:

GCC's compiles, when optimized, are optimized ahead of time.
Clang's compiles, when optimized, are optimized partially ahead of time, partially just in time.

I find Clang compiles to be about 10-20 percent faster for TSCP than GCC, just to give a perspective.

But, personally, I wouldn't use Clang or GCC.

I would use DragonEgg with -fplugin-arg-dragonegg-enable-gcc-optzns for hardcore performance.

Maybe Jim Ablett should give LLVM a try.
