17.4.4.16 .SDATA SECTION
This section collects the small initialized data from all of the application’s input files.
This section is assigned to the data memory region (kseg1_data_mem) with a load
address located in the program memory region (kseg0_program_mem). Symbols are
defined to represent the virtual begin (_sdata_begin) and end (_sdata_end)
addresses of this section.

addresses of this section.
/*
* We want the small data sections together, so
* single-instruction offsets can access them all, and
* initialized data all before uninitialized, so
* we can shorten the on-disk segment size.

17.4.4.17 .LIT8 SECTION
This section collects the 8-byte constants which the assembler decides to store in
memory rather than in the instruction stream from all of the application’s input files. This
section is assigned to the data memory region (kseg1_data_mem) with a load address
located in the program memory region (kseg0_program_mem).

located in the program memory region (kseg0_program_mem). A symbol is defined
