From 34e52abb626c692e19012f9c32c1681141a19cfb Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?M=C3=A5ns=20Rullg=C3=A5rd?= Date: Fri, 22 Jan 2010 03:25:25 +0000 Subject: [PATCH] DECLARE_ALIGNED macro for TMS470 compiler This compiler supports gcc-style alignment attributes for struct, but not for global variables. For the latter, alignment can be specified with a pragma, which does not work for struct members or local variables. By using both pragma and attribute, one or the other will always take effect. Unfortunately, no means exists for aligning stack variables.
