[cfe-dev] alternate clang driver

[reed kotler]

Hi David,

I'm not really trying to sell people on another tool.

It's there if someone else wants to use it.

I found the clang driver to be overly complex and it was slowing down my 
development and to me it should have taken about 10 minutes to set up a 
new port and instead it involved lots of study and doing lots of 
hardcoding regarding specific directories to search and may other such 
things in the compiler which I find fundamentally wrong.

With my driver, I could do new ones in no time and make simple install 
scripts so it can be configured for specific users machine.

I have to fix the builtin clang driver for Mips too and am working on 
that now.
But I find that driver to be fundamentally problematic. It's just my 
opinion.

Differences of opinion is what makes horse races.

I use clang for cross-compiling for ARM, and invoking clang as arm-none-linux-gnueabi-clang, or as clang -ccc-host-triple arm-none-linux-gnueabi enables it to find all of the other bits of the toolchain fine - I'm using it as an almost drop-in replacement for gcc in the WebOS PDK, which shipped with gcc.  The only difficulty it had was finding the various tools, since the Linux toolchain stuff ignores -B, but this was solved with a few symlinks into the sysroot...
