A new option -mmcount-ra-address for gcc 4.5 have been sent by David Daney <ddaney@caviumnetworks.com> in the thread "MIPS: Add option to pass return address location to _mcount", which help to record the location of the return address(ra) for the function graph tracer of MIPS to hijack the return address easier and safer. that option used the $12(t0) register by default, so, we reserve it for it, and use t1,t2,t3 instead of t0,t1,t2.
