re PR target/84564 (error: unable to find a register to spill with -mforce-indirect-call)
PR target/84564
* config/i386/i386.c (ix86_function_ok_for_sibcall): Check for
regparm >= 3 with no arg reg available also for calls with
flag_force_indirect_call. Pass decl to ix86_function_regparm.
* gcc.target/i386/pr84564.c: New test.
