LLVM IR How to pass struct to function - llvm

Question

I'm making my own c-like language and I'm trying to pass a struct to a function. The struct
is representing an array(one member is a pointer to the array and the other member is the length). If I call the function "test" like this: call void #test(%structintarray %a) I get error: '%a' defined with type '%structintarray*' but expected '%structintarray = type { i32*, i32 }' . But if I call "test" like this: call void #test(%structintarray* %a) I get error: '#test' defined with type 'void (%structintarray)*' but expected 'void (%structintarray*)*' I don't understand this second error.
What I'm I doing wrong here?
`
void test(int[] a) {
}
int main() {
int[] a = new int[5];
test(a);
return 0;
}
generates;
%structintarray = type { i32*, i32 }
define void #test(%structintarray %__p__a) {
entry: %a = alloca %structintarray, align 4
store %structintarray %__p__a , %structintarray* %a, align 4
ret void
}
define i32 #main() {
entry: %t0 = call noalias i8* #calloc(i32 5 , i32 4)
%t1 = bitcast i8* %t0 to i32*
%a = alloca %structintarray, align 4
%t2 = getelementptr %structintarray, %structintarray* %a, i32 0, i32 0
store i32* %t1 , i32** %t2, align 4 ; pointer to array
%t3 = getelementptr %structintarray, %structintarray* %a, i32 0, i32 1
store i32 5 , i32* %t3, align 4 ; size of array
call void #test(%structintarray %a)
ret i32 0
}
