30.3.1.1. ARM LDR pseudo-instruction
LDR can be either a regular instruction that loads stuff into memory, or also a pseudo-instruction (assembler magic): http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.dui0041c/Babbfdih.html
The pseudo instruction version is when an equal sign appears on one of the operators.
The LDR pseudo instruction can automatically create hidden variables in a place called the "literal pool", and load them from memory with PC relative loads.
Example: userland/arch/arm/ldr_pseudo.S
This is done basically because all instructions are 32-bit wide, and there is not enough space to encode 32-bit addresses in them.
