[LLVMdev] question when -march=mips

Hi everyone

The c code is like below

extern int function_0(int, int);

int main(){
  return function_0(8, 9);

I compile it as below

llvm-gcc    main.c -emit-llvm -c  -O3   -o main.bc
llc     main.bc -relocation-model=static  -march=mips -O0  -o main.s

It seems no argument is provided to function_0

       addiu $sp, $sp, -8
       sw     $ra, 0($sp)
       jal      function_0

What's the reason?
