−The present package is a basic standalone disassembler for the ARMv4T
+
−instruction set implemented on the ARM7TDMI CPU core, commonly used in classic
+
−cellular phone baseband processors.  The armdis utility interprets an arbitrary
+
−raw binary image (i.e., one being reverse-engineered) as 32-bit ARM
+
−instructions; thumbdis interprets the same image as 16-bit Thumb instructions.
+
−
+
−The form in which the disassembly output is presented is a look-and-feel copycat
+
−of GNU objdump: armdis is meant to replace
+
−
+
−objdump -b binary -m arm -EL -M reg-names-std -D unknown-firmware.bin

−objdump -b binary -m arm -EL -M reg-names-std -M force-thumb -D unknown-fw.bin

−Aside from sparing the operator from having to remember all those options
+
−every single time, and aside from being an independent from-scratch
+
−implementation (lean and mean, only knows how to disassemble those instructions
+
−which are meaningful on ARM7TDMI), these tools have one other feature which
+
−partly prompted me to write them: whenever *dis disassembles a PC-relative
+
−ldr instruction, it shows the value pulled from the literal pool on that ldr
+
−line.  In the reverse engineering jobs I've had to do, it has been a very
+
−valuable feature for me.
