Diese Funktion ist oft Teil eines Maschinensprachemonitors oder sonstigen Hilfsprogrammen, die direkt am Zielsystem aktiv sind

Ein Disassembler zeigt den Inhalt eines Speicherbereichs, der als Maschinencode aufgefasst wird, in einer Darstellung mit entsprechenden Mnemonics für eine passende CPU an.

Explore executables by dissecting its sections, strings, symbols, raw hex and machine level instructions

A disassembler differs from a decompiler, which targets a high-level language rather than an assembly language Disassemble On Demand A lightweight, online service for when you don't have the time, resources, or requirements to use a heavier-weight alternative. The specified number of objects of the specified size are printedĭefaults for format and size letters are those previously used.ĭefault count is 1.A disassembler is a computer program that translates machine language into assembly language-the inverse operation to that of an assembler. Size letters are b(byte), h(halfword), w(word), g(giant, 8 bytes). T(binary), f(float), a(address), i(instruction), c(char), s(string)

When gdb stops, Display the disassembly of the next instruction (manually)ĪDDRESS is an expression for the memory address to examine.įMT is a repeat count followed by a format letter and a size letter.įormat letters are o(octal), x(hex), d(decimal), u(unsigned decimal),.

Multi-thre process 3718 In: _libc_start_main Line: ? PC: 0x7ffff740d76d Line 3 of 'main.c' starts at address 0x401050 and ends at 0x401075 : push %ebp The /m option in gdb is similar to option -S in objdump.

(gdb) disassemble /m main // update: /m is deprecated, use /s a.out.(no debugging symbols found).done.ĭump of assembler code for function main: l, -line-numbers Include line numbers and filenames in output S, -source Intermix source code with disassembly d, -disassemble Display assembler contents of executable sections

To generate assembly code using gcc use the -S option: gcc -S hello.c.

Compile the program in gcc with debug symbols enabled ( -g).
