However disassembling the resulting elf file shows the sections system_fpc_cpuuint, system_sysinitfpu, fpc_initializeunits, fpc_initializeunitsetc, system_internalexit, fpc_do_exit, system_system_exit and init$_system to be 32 bit arm code not thumb2. The rest of the program, including the stellaris.pp code, are correct thumb2 code.

Do you have an example of how you can see it is 32 bit arm code and not 
thumb2?
