### Assembler code ### Assembler code
Some examples are meant to show the assembler code they generate. Some examples are meant to show the assembler code they generate.
To see that, one can use for example https://godbolt.org/ or GDB. To see that, one can use for example https://godbolt.org/ or objdump or GDB.
With GDB: As objdump cannot only dump a specific function, here is the GDB version:
```bash ```bash
gdb -q -ex 'disassemble main' -ex q "${program_to_execute}" gdb -batch -ex 'set disassembly-flavor intel' -ex 'set print asm-demangle on' -ex 'disassemble main' "${program_to_execute}"
```
One can create an alias to ease the usage of GDB:
```bash
alias disas="gdb -batch -ex 'set disassembly-flavor intel' -ex 'set print asm-demangle on' -ex 'disassemble main'"
disas "${program_to_execute}"
``` ```
