lfn, master, serial, ticket/834-toolchain-update, topic/msim-upgrade, topic/simplify-dev-export

Children:

Parents:

Message:

Introduce the notion of FPU_NO_CFLAGS and separate building of test/fpu
objects and building the rest of kernel objects. Now, amd64 and ia32 can
enable things such as SSE selectively for the test/fpu/*.
