Alex, thank you for your reply.

One quick newbie query,

once i install clang/llvm on a box running 2.5.1-DEVELOPMENT,
can i just specify CCVER=clang make ... ?

You can.

Here's a small patch that makes world build with clang (kernel should build out of the box):


To build world, do:

env WORLD_CCVER=clang make -DNO_GCC44 -DNO_WERROR buildworld

For the kernel, likewise:

env WORLD_CCVER=clang make buildkernel KERNCONF=...
