bss Section
The bss section is used for local common variable storage. You may allocate
address space in the bss section, but you may not dictate data to load into it
before your program executes. When your program starts running, all the contents
of the bss section are zeroed bytes.
Addresses in the bss section are allocated with special directives; you may
not assemble anything directly into the bss section. Hence there are no bss
subsections.
