When mesa git fa46848e51a619aba5a748316fe8fe4c2e17d243 is built against LLVM 3.8.0, with a Radeon R9 270, support for the GL_ARB_shader_storage_buffer_object extension is claimed. However, GL_MAX_COMBINED_SHADER_STORAGE_BLOCKS is 0. The minimum required by the ARB_shader_storage_buffer_object specification is 8.
https://cgit.freedesktop.org/mesa/mesa/commit/?id=bfd11c599600960f966d5d217b... makes it look as if support was only intended for LLVM 3.9 or later.
