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.
You might have to use the .W suffix to get the maximum offset range or to generate addresses
that are not word-aligned. See
Rd must not be SP and must not be PC.
This instruction does not change the flags.
