I'm reading the sdcc source code now, I'm so bothered with two questions.

FIRST,  Is it available (set *dynDirectBitRegs) int the source code of PORT PIC14?
    If available, What is it content? Please give me one example.

SECOND,the register only allocated to the temporary, So How the global variable's register allocated?

Please help me, I'm so confused with these, has lost all desire for the food and drink..

Thanks, Guys..
live long and prosper..
