No. It enables AMDGPU target these days, which is for the modern stuff and very much needed by them. r600 stuff was in the llvm 3.3-3.6 era, which was used by old experimental mesa[r600-llvm-compiler] as an alternative shader compiler for r600 instead of builtin mesa stuff. This work has been ditched long ago afaik. Instead now VIDEO_CARDS=radeon is required on llvm for radeonsi and later AMD GPUs for _ANY_ shader compiler support at all, plus other things (from it adding AMDGPU to llvm targets in current ebuild). > The new system will be applied to 3.9.0 and 9999 ebuilds.

People with radeonsi graphics set VIDEO_CARDS=radeon already, I'm a bit reserved about having to force them to set some LLVM_TARGETS=radeon or LLVM_TARGETS=amdgpu on top of that to satisfy some USE depends on mesa[video_cards_radeon].
