Tool/software: TI C/C++ Compiler
ccs version is 8.20
there are same information about how the compiler save B3 when calling a function in《TMS320C6000 Optimizing Compiler v8.2.x User's Guide》.
so, i write some c functions,and debug on c6748 with ccs.but the result puzzled me.
the compiler saves B3 with registers(eg. A31/A30/B6 ...) instead of stack.
Why the result of compile conflicted with User's Guide. What is the saving rule for B3 when calling a function?
the result is effected by compiler options? there are some other particular User's Guide?
