Hey Virgile,<br>
<br>
I gave this a go and it's working with simple gcc-cygwin compiled
executables, nice!<br>
<br>
I went to try and integrate some early PDB loading work I did into
it (it goes via DIA), but sadly looks like my home machine has
decided PDBs are evil and, well, corrupted my local repo! It was
some time ago I looked at it (at least November last year). I'll
probably have a look at seeing if that can work again, at least
symbol information would be a great start. I think I'd only got as
far as symbols anyway.<br>
<br>
Again, nice work! Need to work together at getting this back to
trunk.<br>
<br>

<div>Sure, that would be great to
combine effort! Quite happy people
are willing to join, it's quite a
huge task. And your goal being
little bit different is good to have
more test cases and features.</div>
<div>I'm quite open about how to
coordinate. On my side, I think I
just need a few days to clean up and
rearrange commits little bit more
before starting a proper branch,
then we could start to work from
that?</div>

<div>Actually I have never tried

it to work -- good to know process

<div>Also, some scenarios that used to
work for me 6 months ago don't work
anymore now, so that might be
related as well. I'll try to fix
those regressions quickly so that
your work doesn't bump into them.</div>

<div>Hi Virgile,<br>
<br>
This looks great!
We had recently
started on our own
Windows Process
plugin
implementation,
porting code we
had used in a
simple custom
debugger to LLDB,
however I think it
would make sense
to combine our
efforts. I would
be happy to help
stabilize what you
have so far, I
built locally from
your repo and much
of the process
control works
great though I
haven't had any
luck getting debug
info in stack
traces in a few
simple apps built
with gcc
(-gdwarf-2) or
with clang using
lldb.exe yet.<br>
<br>
</div>
What we're aiming
for is slightly
different than you,
we're mostly
interested in the
ability to parse
ELF/Dwarf debug info
from code produced
by MCJIT since the
bulk of our software
currently needs to
be compiled with
MSVC. This relies on
a JIT support patch
(currently for
Linux) which hasn't
yet been submitted
upstream, though
your work here is
probably the push
required for me to
get that done.<br>
<br>
</div>
I will take a pass
through some samples
on this end and take
note of any issues I
come across and then
start looking into
them. Let me know how
you would like to
coordinate work here
(assuming you would
like to coordinate)
and we can go from
there.<br>
<br>
</div>
Nice work!<span><font

<div dir="ltr">Hello,
<div><br>
</div>
<div>6 months
ago I worked
on LLDB to add
Windows
process
debugging
support.</div>
<div>
<br>
</div>
<div>I had to
put this
project little
bit aside for
a little bit.
Now that I
have some more
time to focus
on that
project again,
I wanted to
share what I
have been
doing so far,
and hopefully
as it gets
more mature it
would be great
to have it
merged in
trunk later.</div>
<div><br>
</div>
<div>So far I
pushed most of
my changes on
github:</div>
<div><a
moz-do-not-send="true"
href="https://github.com/xen2/lldb/commits/msvc12" target="_blank">https://github.com/xen2/lldb/commits/msvc12</a><br>
</div>
<div><br>
</div>
<div>
The most
important
commit is
probably
"Added
ProcessWindows
and
DynamicLoaderWindows
plugins.".
Some of the
commits might
be only
temporary
(needed for
debugging to
work). Some
others commits
are
trivial/minor
and could
probably be
cherry-picked
immediately in
trunk.</div>
<div><br>
</div>
<div>It is far
from being
ready to be
merged yet
(unpolished
commits, lot
of file
rearrange/rename,
code sharing,
cleanup and
comments to do
here and
there).<br>
</div>
<div><br>
</div>
<div>Also, at
the time
(might have
been fixed
yet), I used
Linux
implementation
as a guideline
but noticed it
didn't seem to
work for
multithreading
(StopInfo
mixing up each
other). As a
result I had
to change some
stuff to have
multithreading
working. That
might be
something that
could be
interesting to
have back on
Linux as well.</div>
<div><br>
</div>
<div>Status: I
am now able to
use LLDB as a
library to
actually debug
real windows
processes
(including
stack traces,
variables,
multithreading,
etc...) on
simple
executables
(compiled with
either gcc
with
-gdwarf-2, or
clang).</div>
<div><br>
</div>
<div>Note: I
might force
push the
branch msvc12
on github
since I want
to rewrite
some commits
and rebase. If
people are
interested in
helping,
please let me
know and I
would stop
doing that.</div>
<div><br>
</div>
<div>Hope it
will help
starting the
effort to have
a full
debugging
support on
Windows!</div>
<div><br>
</div>
<div>Thanks</div>
