Message:

initial Clang support

this is more like a proof-of-concept (tested with Clang and LLVM 2.6-pre1)

• it is limited to ia32/amd64, but it will probably fail except compiling ia32 target on ia32 host
• actually only Clang as compiler is used, native binutils are used for standalone assembler files and linking
• kernel compiles fine, boots and even prints some scrambled initial messages to the framebuffer, but panics soon after that (it might be just a tiny glitch in output functions)
• uspace compiles mostly fine, but the linking fails

• uspace/lib/libc/Makefile.toolchain (modified) (3 diffs)
