Where can get libc_p.so source code?

I'd like to profiling my owned process in target hardware, I only can check the source code as libc.so since there is no libc_p.so available for my开发者_开发百科 MIPS target hardware. I expect: I, There is MIPS libc_p.so library available; OR II,There is libc_p source code available, that I can compile the MIPS library by myself.

I'm looking forward to good proposal from you experts.

libc_p.so is just a binary of libc compiled with the profiling options to the compiler/linker. The source is the same.
