[cfe-dev] Clang and -mcmodel=large

Hello all,

I'm developing a hobby kernel for x86-64 machines,
and I put the kernel into the higher half.

I'm trying to switch from GCC to Clang, but it seems
that the latter doesn't support the -mcmodel=large
option, which is required in order to put the kernel
at the 0xFFFF800000000000 in virtual memory,
as specified in my linker script:

Any workarounds or plans for implementing that feature
in the Clang compiler?
