Chris Wilson ab7529f244 drm/i915: Use __is_constexpr() ... gcc-4.8 and older dislike the use of __builtin_constant_p() within a constant expression context, and so we must use the magical __is_constexpr() instead. For example, with gcc-4.8.5: ../drivers/gpu/drm/i915/i915_reg.h:167:27: error: first argument to ‘__builtin_choose_expr’ not a constant ../include/linux/build_bug.h:16:45: error: bit-field ‘<anonymous>’ width not an integer constant Reported-by: Randy Dunlap <rdunlap@infradead.org> Reported-by: Uma Shankar <uma.shankar@intel.com> Fixes: baa09e7d2f ("drm/i915: use REG_FIELD_PREP() to define register bitfield values") Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Cc: Jani Nikula <jani.nikula@intel.com> Cc: Imre Deak <imre.deak@intel.com> Cc: Randy Dunlap <rdunlap@infradead.org> Acked-by: Randy Dunlap <rdunlap@infradead.org> # build-tested Reviewed-by: Jani Nikula <jani.nikula@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20190320154021.5244-1-chris@chris-wilson.co.uk		2019-03-21 09:59:29 +00:00
