From 90e6b048365950416419c031f2f2d9a8afb5b70c Mon Sep 17 00:00:00 2001 From: Russell King Date: Thu, 10 Jan 2008 17:07:08 +0000 Subject: [ARM] vfp: fix fuitod/fsitod instructions These two instructions exceptionally take a single precision register as their operand. This means we can't use vfp_get_dm() to read the register number - we need to use vfp_get_sm() instead. Add a flag to indicate this exception to the general rule.
