From 4fbf23238e3f927871576170d1a38c855e04473e Mon Sep 17 00:00:00 2001 From: Bernhard Rosenkraenzer Date: Fri, 19 Sep 2014 01:50:16 +0200 Subject: Allow building on clang without __builtin_assume_aligned Clang versions up to and including 3.5 don't have __builtin_assume_aligned. Define it to a reasonable approximation when building with those.
