Subject: Disassembling ARM and Thumb code
Date: Fri, 06 May 2005 00:06:00 -0000	[thread overview]
Message-ID: <7f45d93905050517053a33f3c9@mail.gmail.com> (raw)

My ARM7TDMI processor is currently in Thumb mode, but the x/i command
dissects the instruction as an ARM instruction. The symbol
rdp_getargvsp is a Thumb symbol added using add-symbol-file [elf
binary here]. What is the command to disassemble a given memory
location as a Thumb instruction?

Thanks,
Shaun

(gdb) p/x $cpsr
$10 = 0x4000003f
(gdb) x/i $pc
0x20004dc <rdp_getargvsp>:      cmpcs   r4, #67108864   ; 0x4000000
(gdb)
0x20004e0 <rdp_getargvsp+4>:    strmibt r2, [r9], -r0, lsl #8
