Why not push these registers in your function before use?

Big parameter list? Have you considered simply passing a pointer to a
structure?

Hold it right there. You're writing a C function. If it wants to
take values from other functions, put them in the argument list, not
in registers.
C is not assembler, so don't pretend otherwise. One of the
differences is that you *have to* give up control over the CPU
registers, and leave them to the C compiler to work with.
You're fighting the C compiler instead of using it. Don't.

How to force the compiler to use stack as parameter passing for a
particular function (for recursive functions)?
Infact, my function isnt a recursive one, but has a big parameter list.
Due to this, the register values are being tampered, which were set by
other functions. SO, i want the compiler to use stack for this
particular function for its parameter calling.
Thanx in advance
