Taking a look at the C Compiler output "main.ps" you will find that the CODE and the BSS sections are defined
by the Compiler.
<main.ps>
The symbol of global variable i is defined, and a 4-byte area is located in the BSS section by the ".comm"
pseudo-instruction. Since variables j and k are local variables, they are allocated to general-purpose registers and
stacks. No BSS section is used for these variables.
When these modules are linked by make in the tutorial, separate CODE sections are combined into one section.
During a linking, each file and each section can be address-specified so that they correspond to the actual
memory configuration. For details, refer to Section 12, "Linker".
