Translation of C code to MIPS (simple function call that does a for-loop)

Question

I have the following C Code that I have translated into MIPS.

// TEST 1, comment out when running with TEST2
int sx[5] = {1, 2, 3, 4, 5};
int sy[5] = {5, 4, 3, 2, 1};

// TEST 2, uncomment when running with TEST2
//int sx[5] = {1, 2, 3, 4, 5};
//int sy[10] = {1, 0, 1, 0, 1, 0, 1, 0, 1, 0};

void g(int sa, int incx, int incy)
{
  int i, ix, iy;
  
  if (incx == 1 && incy == 1) {
    for (i=0; i<5; i++)
      sy[i] = sy[i] + sa*sx[i];
  }
  else {
    ix = 0, iy = 0;
    for (i=0; i<5; i++) {
      sy[iy] = sy[iy] + sa*sx[ix];
      ix = ix + incx;
      iy = iy + incy;
    }
  }
}

main()
{
  g(2, 1, 1); // TEST1
  //g(2, 1, 2); // TEST2
}

Here is the following MIPS code. Note that the output is correct when compared to output of C code. But were calling conventions used correctly? For academic plagiarism purposes, I am leaving out most of the arithmetic instructions that is done inside the if-then / for-loops.

I also would like to know whether the .end g at the end of my translation is in the right spot. I lost track of it and now I have no clue where it should go (I assume after the nop in g?)

    .global main
    
    .data
## TEST 1
sx: .word 1, 2, 3, 4, 5
sy: .word 5, 4, 3, 2, 1
    
## TEST 2
#sx: .word 1, 2, 3, 4, 5
#sy: .word 1, 0, 1, 0, 1, 0, 1, 0, 1, 0
    
    .text
    .ent main
main:
    ## TEST 1
    li      $a0, 2  # int sa
    li      $a1, 1  # int incx
    li      $a2, 1  # int incy
    
    ## TEST 2
    #li     $a0, 2  # int sa
    #li     $a1, 1  # int incx
    #li     $a2, 2  # int incy
    
    jal     g       # function call to g

loop:
    j   loop
    nop
    .end main
    
    .ent g
    
## void g(int sa, int incx, int incy)
g:
    li      $s0, 0  # int i = 0
    li      $s1, 0  # int ix = 0
    li      $s2, 0  # int iy = 0
    
    ## if (incx == 1 && incy == 1) {
    # for (i=0; i<5; i++)
      # sy[i] = sy[i] + sa*sx[i];
      
    ## if either incx or incy are not equal to 1, branch to L2
    bne $a1, 1, L2
    nop
    bne $a2, 1, L2
    nop
## if-body
L1:
    slti    $t0, $s0, 5     # if $s0 (index i) is less than 5, set $t0 to 1
    beqz    $t0, loop       # if $t0 = 0 (meaning i >= 5), exit if-block
    nop 

### arithmetic code

    sw      $t7, 0($t4)     # loads $t7 into sy[i]
    addi    $s0, $s0, 1     # i++
    j       L1
    nop
## else-body
L2:
    slti    $t0, $s0, 5     # $s0 (index i) is less than 5, set $t0 to 1 
    beqz    $t0, loop       # if index i reaches max, exit to loop
    nop

#### arithmetic code

    sw      $t7, 0($t4)     # $t7 (arithmetic) stored into address for sy[iy]
    addi    $s0, $s0, 1     # i++
    j L2
    nop
    .end g
