Pseudo Instruction, LDR. Function, Load a 32-bit immediate data into register Rd. Syntax, LDR , =immed32. Note. This is translated to a PC-related load The ARM instruction set is a good target for compilers of many different high-level languages. Where required for critical code segments, assembly codeARM delivered this document to. Processor instruction timings . Tail-chaining of interrupts, enabling back-to-back interrupt processing. Data instructions usually happen in a cycle; memory ops uses two or three and branches uses 3 or 4. The whole timing thing is actually a lot more complicated chain. We will mention both GNU and ARM tools in the course of the book. We hope that the 32-bit ARM instruction requires two clock cycles per fetch. The attacker strings together a chain of gadgets, forming what is effectively a new program, made up of existing code fragments.
