网上说用set arm force-mode thumb ,经过实践,只有Android的gdb与gdb_server是有这条命令的,调试IOS的gdb没有.如下
(gdb) set arm force-mode thumb
Undefined set arm command: "force-mode thumb". Try "help set arm".
(gdb) help set arm
Various ARM-specific commands.
List of set arm subcommands:
set arm abi -- Set the ABI
set arm apcs32 -- Set usage of ARM 32-bit mode
set arm disassembler -- Set the disassembly style
set arm fpu -- Set the floating point type
set arm show-opcode-bytes -- Set ARM and Thumb opcode byte display in disassembly
set arm single-step -- Set the ARM stepping mode
Type "help set arm" followed by set arm subcommand name for full documentation.
Command name abbreviations are allowed if unambiguous.
