How to make Eclipse disassemble the code in Intel syntax

Question

I use Eclise CDT as a development environment. I use disassembly view to see assembly equivalents. But I am used to read an write assembly code in Intel syntax. Is there any option to make the Eclipse dump the assembly code in Intel syntax?

Answer 1

Create a file with set disassembly-flavor intel in it, you can use ~/.gdbinit as the file if you want.

Then point your launch configuration at the file you created.

Without the launch configuration change your disassembly may look like:

15                  puts("!!!Hello World!!!"); /* prints !!!Hello World!!! */
000000000040053a:   mov     $0x4005d4,%edi
000000000040053f:   callq   0x400410 <puts@plt>

With the gdb init file you get the Intel syntax:

15                  puts("!!!Hello World!!!"); /* prints !!!Hello World!!! */
000000000040053a:   mov     edi,0x4005d4
000000000040053f:   call    0x400410 <puts@plt>

Note CDT does not pick up ~/.gdbinit unless you explicitly set it in the launch configuration. Here is a screenshot of the launch configuration:

Globally

You can make the change global (for all new launch configurations at least) by setting the GDB command file in the preferences too:
