Load PC-relative address.
ADR{cond} Rd, label
where:
cond
Rd
label is a PC#relative expression. See Section 3.3.6 (p. 42) .
ADR determines the address by adding an immediate value to the PC, and writes the result to the
destination register.
ADR produces position#independent code, because the address is PC#relative.
If you use ADR to generate a target address for a BX or BLX instruction, you must ensure that bit[0] of
the address you generate is set to1 for correct execution.
Values of label must be within the range of #4095 to +4095 from the address in the PC.
Note
Rd must not be SP and must not be PC.
This instruction does not change the flags.
Load and Store with immediate offset, pre-indexed immediate offset, or post-indexed immediate offset.

is the destination register.
You might have to use the .W suffix to get the maximum offset range or to generate
addresses that are not word-aligned. See Section 3.3.8 (p. 45) .
