From 5c8759087d9cdd12c937a704ea8225f2e4c00ba6 Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Thu, 12 May 2016 13:22:29 +0100 Subject: [PATCH] hw/display/blizzard: Expand out macros Now that we can assume that only depth 32 is possible, there's no need for the COPY_PIXEL1 and PIXEL_TYPE macros, and the SKIP_PIXEL, COPY_PIXEL and SWAP_WORDS macros aren't used at all. Expand out COPY_PIXEL1 and PIXEL_TYPE where they are used, delete the unused macro definitions, and expand out the uses of glue(name_prefix, DEPTH).
