From 26a5e69aafd0434922316e4185c45c9bddd4b9ba Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Tue, 7 Dec 2010 15:37:34 +0000 Subject: ARM: Ignore top 16 bits when doing VCVT from 16 bit fixed point VCVT of 16 bit fixed point to float should ignore the top 16 bits of the source register. Cast to int16_t and friends rather than int16 -- the former is guaranteed exactly 16 bits wide where the latter is merely at least 16 bits wide (and so is usually 32 bits).
