so file using gdb, use the following command: gdb (gdb) disassemble main 3) radare2: Radare2 is a reverse engineering tool that can be used to decompile a. so file using objdump, use the following command: objdump -d 2) gdb: The gdb tool can also be used to decompile a. This tool is included in the binutils package. 1) objdump: The objdump tool can be used to decompile a. However, it is possible to do so using a few different tools.

( Compiler Explorer is also a useful resource for that see How to remove 'noise' from GCC/clang assembly output? for more about it and writing small functions that compile to interesting asm.Most people believe that it is not possible to decompile a. (Unlike GNU objdump where you'd need a separate per arch, like aarch64-linux-gnu-objdump -d.) Similarly, clang -O3 -target mips -c or clang -O3 -target riscv32 -c or whatever are useful to compile for architectures you're interested in, but not interested enough to bother installing a cross-compiler. Llvm-objdump -d also works, and can disassemble for a variety of architectures from a single binary. ( -w is no line-wrapping, -C is demangle, -r prints relocations in object files.) I use alias disas='objdump -drwC -Mintel' on my system.

If you don't want to install it objconv, GNU binutils objdump -drwC -Mintel is very usable, and will already be installed if you have a normal Linux gcc setup. Note: Immediate operand could be made smaller by sign extensionĭoesn't have anything in the source to make sure it assembles to the longer encoding that leaves room for relocations to rewrite it with a 32bit offset. plt align=16 execute section number 11, code It might not be, though, since disassembly of stuff like (from /lib/x86_64-linux-gnu/libc.so.6) (So you aren't limited to keeping things the same size.) With no changes, the result should be near-identical. Note that this output is ready to be assembled back into an object file, so you can tweak the code at the asm source level, rather than with a hex-editor on the machine code. It can disassemble into NASM, YASM, MASM, or GNU (AT&T) syntax. It's open source, and easy to compile for Linux. It also indicates NOPs more clearly than other disassemblers (making it clear when there's padding, rather than disassembling it as just another instruction.)

Other disassemblers usually disassemble jump instructions with just a numeric destination, and don't put any marker at a branch target to help you find the top of loops and so on. (It doesn't recognize - as shorthand for stdout, and defaults to outputting to a file of similar name to the input file, with.

It will add comments to the disassembly output for performance problems (like the dreaded LCP stall from instructions with 16bit immediate constants, for example).

Portable tools that can disassemble AArch64, MIPS, or whatever machine code include objdump and llvm-objdump.Īgner Fog's disassembler, objconv, is quite nice.
