Incorrectly uses 32-bit wide subtract instruction for the expression: (int40_t) var1_int32_t - (int40_t) var2_int32_t

      The attached test case has this statement ...

          result = (int40_t)a32 - (int40_t)b32;

      a32 and b32 are int32_t. result is int40_t. Thus, this subtraction should be 40 bits wide. However, this instruction is used ...

                 SUB     .L2     B5,B4,B5:B4

      That only computes a 32-bit wide result.
