Hi,
No.. total number of arguments that u can pass to a function is not 4 for sure.. I had similar
kind of problem with my system... the thing is the arguments are being passed thru regsiters
and if all registers are used up then thru stack...
The reason I see for changing values ( when u pass them to function) is because after you pass
the arguments.. the registers are used by the processor to perform different tasks so the
register no longer represents the variable.. ( wht i mean to say is regsiter is not fixed
address of the variable) value of variable is placed on to stack .. and later on accessed back
when needed.. all this is internally taken care of by compiler .. provided u hav proper stack
allocation .. ..
I would definately recommend you to go thru part 8.4 Run time Environment (
of TMS320C6000 Optimizing Compiler User’s Guide (SPRU187K)

hope this helps..
