This patch implements the final bits of CMSE code generation: * emit special linker symbols * restrict parameter passing to no use memory * emit BXNS and BLXNS instructions for returns from non-secure entry functions, and non-secure function calls, respectively * emit code to save/restore secure floating-point state around calls to non-secure functions * emit code to save/restore non-secure floating-pointy state upon entry to non-secure entry function, and return to non-secure state * emit code to clobber registers not used for arguments and returns * when switching to no-secure state Patch by Momchil Velikov, Bradley Smith, Javed Absar, David Green, possibly others.
