View Both Assembly and C code

Question

Do we have a way to view assembly and c code both using gdb.

disassemble function_name shows only assembly, I was trying to find a way to easliy map c code to assembly.

Answer 1

Try disassemble /m.

Refer to http://sourceware.org/gdb/current/onlinedocs/gdb/Machine-Code.html#Machine-Code

The format is similar to that of objdump -S, and intermixes source with disassembly. Sample output excerpt:

10      int i = 0;
=> 0x0000000000400536 <+9>: movl   $0x0,-0x14(%rbp)

11      while (1) {
12          i++;
   0x000000000040053d <+16>:    addl   $0x1,-0x14(%rbp)
