[SOLVED] Intel syntax for debugger possible?
lazarus / 12-Debugger

I'm using Lazarus under Linux and I just want to know if it's possible
to make the assembler to display Intel syntax instead of AT&T.

If yes, how?

I tried this: -eval-command="set disassembly-flavor intel" without
success, it gives an error. If that is really possible, what should I
do to make it work?

Thank you!

What error?
The eval command, is how it should work.

Maybe the quotes nee to be set different on linux. Not sure how the
fpc TProcess is parsing them (and if it differs between OS).

Also note, that there is a report, that GDB may become less stable in
that mode.
It is not known why, but in that case (where it actually runs the app,
but then gdb crashes), it clearly is a bug in gdb, that can not be
fixed in lazarus.

Just seen, should it not be (note 2 dashes an start)

--eval-command="set disassembly-flavor intel"

That gives me the same error.

Seems to work for me on windows.

1)
Try on the command line
 gdb --eval-command="set disassembly-flavor intel"

or just gdb and then
set disassembly-flavor intel

2)
if the second one abve works.
open  debugger\gdbmidebugger.pp

line 2817
  ExecuteCommand('set width 50000', []);

insert after
  ExecuteCommand('set disassembly-flavor intel', [],
[cfscIgnoreError]);

recompile the IDE

recompile the IDE
That was on line 1922. And when trying to compile, it stopped with the
following error:

Quote from: Free Pascal
Compiler/usr/share/lazarus/1.0.2/debugger/gdbmidebugger.pp(1923,70)
Error: Identifier not found "cfscIgnoreError"

Any suggestion for that? Thanks for helping!

ah you are on the 1.0x branch, I overlooked that.

Just do

 ExecuteCommand('set disassembly-flavor intel', []);

Difference is, if it fails, it will not be ignored.

I put the option in quotes and that worked, both on Windows and Linux
versions:
Code: [Select]"--eval-command=set disassembly-flavor intel"
