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
nop
…
What’s the reason?
Thanks
