9.100 --rwpi

Makes the load and execution region containing the RW and ZI output section position-independent.

Usage

If this option is not used the region is marked as absolute. This option requires a value for --rw_base. If --rw_base is not specified, --rw_base=0 is assumed. Usually each writable input section must be Read-Write Position-Independent (RWPI).
If this option is selected, the linker:
  • Checks that the PI attribute is set on input sections to any read-write execution regions.
  • Checks that relocations between sections are valid.
  • Generates entries relative to the static base in the table Region$$Table.
    This is used when regions are copied, decompressed, or initialized.

Restrictions

You cannot use --rwpi:
  • With --scatter.
  • If an object file contains execute-only sections.
