ARM disassembly [closed]

Question

Is there a tool which analyzes and can highlight what each line of code means. I am not looking for a decompiler like that of Hex-Rays Decompiler. I am looking for a simple tool that shall be of assistance in reading the assembly code.

Answer 1

What about using objdump?

$ cat add.c 
int add(int a, int b) {
    return a + b;
}

$ arm-linux-gnueabihf-gcc -c -O2 add.c

$ arm-linux-gnueabihf-objdump -d add.o

add.o:     file format elf32-littlearm


Disassembly of section .text:

00000000 <add>:
   0:   1840        adds    r0, r0, r1
   2:   4770        bx  lr

It can provide source code mixing as well if your object file contains debug information (gcc -g) and if you supply -S to objdump.

Answer 2

The Online Disassembler (ODA) supports ARM and a myriad of other architectures. You can enter binary data in the Live View and watch the disassembly appear as you type, or you can upload a file to disassemble. A nice feature of this site is that you can share the link to the disassembly with others.

Answer 3

As you mentioned in your question, IDA Pro can disassemble ARM too.
Besides, have you tried ARM DS-5 Development Studio?
Some features are more hardware-related, but the IDE (Eclipse) is very nice.

Features:

• Debug support for bare-metal, RTOS, Linux, and Android platforms
• Non-intrusive cycle-accurate ETM and PTM instruction tracing
• Seamless support for SMP systems
• Automated debug sessions for faster debug cycles
• ITM and STM instrumentation tracing
• Support for pre-configured and custom platforms

In the manual it says it contains:

• DS-5 Debugger, covering all stages of product development
• ARM Compiler 5.04 for embedded and bare-metal code
• Linaro GCC Toolchain 2013.03 for Linux applications and Linux kernel
• ARM Streamline™ Performance Analyzer for various operating systems, including Linux, Android and RTX
• Eclipse IDE, source code editor and project manager
• Fixed Virtual Platforms (FVP) for Cortex™-A8 and quad-core Cortex-A9 processors
• Example projects and documentation
