On ARM, in Thumb mode r7 is used for the framepointer; this meant that we would fail to compile in debug mode because we were using r7 for TCG_AREG0. Shift to r6 instead to avoid this clash. (Bug reported as LP:870990.) Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Andrzej Zaborowski <andrew.zaborowski@intel.com>
