gdb/arm: Fetch initial sp value prior to compare
For Arm Cortex-M33 with security extensions, there are 4 different stack pointers (msp_s, msp_ns, psp_s, psp_ns). In order to identify the active one, compare the values of the different stacks. The value of the initial sp register needs to be fetched to perform this comparison. Signed-off-by: Torbjörn SVENSSON <torbjorn.svensson@foss.st.com> Signed-off-by: Yvan Roux <yvan.roux@foss.st.com>
