From 0ee3ac938abdc15b26779780c0c94cfe71570b5d Mon Sep 17 00:00:00 2001 From: Richard Sandiford Date: Wed, 19 Mar 2014 17:09:14 +0000 Subject: util: Turn inv_swizzle into a global function MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit With the big-endian changes, there can be two swizzle orders for each format. This patch turns Format.inv_swizzle() into a global function that takes the swizzle list as a parameter. There is no change to the generated u_format_table.c.
