##### 9.1.3.3 Relocations

Relocations for ``MOVZ`' and ``MOVK`' instructions can be generated by prefixing the label with ``#:abs_g2:`' etc. For example to load the 48-bit absolute address of foo into x0:

                 movz x0, #:abs_g2:foo		// bits 32-47, overflow check
                 movk x0, #:abs_g1_nc:foo	// bits 16-31, no overflow check
                 movk x0, #:abs_g0_nc:foo	// bits  0-15, no overflow check

Relocations for ``ADRP`', and ``ADD`', ``LDR`' or ``STR`' instructions can be generated by prefixing the label with ``:pg_hi21:`' and ``#:lo12:`' respectively.

For example to use 33-bit (+/-4GB) pc-relative addressing to load the address of foo into x0:

                 adrp x0, :pg_hi21:foo
                 add  x0, x0, #:lo12:foo

Or to load the value of foo into x0:

                 adrp x0, :pg_hi21:foo
                 ldr  x0, [x0, #:lo12:foo]

Note that ``:pg_hi21:`' is optional.

                 adrp x0, foo

is equivalent to

                 adrp x0, :pg_hi21:foo
