I've been doing microcontroller stuff for 25+ years, almost all in C,
and I don't think I've never seen such a compiler.  Even on the
register-starved 6800 architecture, the first parameter was passed in
a register.  On architectures with more registers (H8, MSP430, ARM,
etc.) It's usually the first 3 or so parameters that are found in
registers.
