TMS570: do the tools perform the initialization of the R4F registers for CCM?

Hi,

with reference to the RTM and to http://e2e.ti.com/support/microcontrollers/hercules/f/312/p/159583/580633.aspx#580633  ,  the CPU registers and return stack must be initialized before being used for the first time, to avoid CCM errors after PORST or resets due to STC.

Where is this inizialization usually done? Does the compiler Run Time Support Library take care of it? Or shall we better have an inizializion routine before jumping to the C compiler init code?

Thanks,
Massimo
