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
