In ARMv7 and previous, the program counter is an ordinary register, so you can perform a load relative to the PC for anything that doesn't fit into a register's literal field. Compilers typically emit so-called literal pools before the entry or after the exit point of each function (or sometimes before a basic block inside very large functions). Some compilers support literal pool merging as a code size reduction technique, too. Edit: Also, ARMv8 has dedicated instructions for for pc-relative loads and jumps.
