This option enables the PID facility.
See "4.2.6.1 Allocation of function and data to section" and "8.6 PIC/PID Facility" for details about the PID facility.
When this option is specified, the section to which variable data is output is changed from the data or bss attribute section to the sdata32 or sbss32 attribute section, respectively. |
Referencing variable data allocated to the sdata32 or sbss32 attribute section is always performed in GP-relative mode. This allows the sdata32 or sbss32 attribute section to be allocated at a desired address after linkage. |
