[Detailed description]

-

The PIROD facility makes the section to which constant data, such as const variables or string literal, is allocated position-independent.

See "4.2.6.1 Allocation of function and data to section" and "8.6 PIC/PID Facility" for details about the PIROD facility.

-

When this option is specified, the section to which constant data is output is changed from the const attribute section to the pcconst32 attribute section.

-

Referencing constant data allocated to the pcconst32 attribute section is always performed in PC-relative mode. This allows the pcconst32 attribute section to be allocated at a desired address after linkage.

-

When this option is specified, the predefined macro __PIROD will be valid.

-

If this option is not specified simultaneously with the -pic option, an error will occur.

-

If this option is specified simultaneously with the -Omap or -Osmap option, an error will occur.
