23.3.4.18 .lit8 Section

This section collects the 8-byte constants (usually floating-point) 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).
