![]() ![]() Similarly, we can run the same command on the object file to disassemble the code: $ objdump -d test.oĤ: c7 45 fc 00 00 00 00 movl $0x0,-0x4(%rbp)Īs we can see above, unlike the binary file, the object file shows only the main section.īy default, it shows the disassembly in ATT mnemonic. In order to ensure this is the disassembly, we may modify the C program, compile it and run the objdump command on it again to see the changes. We see the add instruction to add 20 (0x14) to the variable i at the memory address 605. The how-to C and C++ - A Story of a compiler, assembler and linker tutorial - The process of building programs based on C language that includes in-depth. ![]() Designed to be reliable and efficient, this AC/DC converter is an excellent choice for engineers and technicians. So, it is helpful in various electronic equipment, from simple clock generators to digital instruments. Here we can see the relevant main section after stripping off others. The Taitien NA-100M-6822 is a dual-purpose AC/DC voltage converter designed to switch direct current to alternating current. ![]() Since we have used the -d flag, it’ll print all the executable sections. Using the -d option, we can see the assembly code for the binary: $ objdump -d testĥfe: c7 45 fc 00 00 00 00 movl $0x0,-0x4(%rbp)Ī binary file contains a lot of sections in ELF format with address and metadata for properly loading the executable when it is launched. ![]()
