Eli:
In this message:
https://sourceware.org/ml/gdb-patches/2018-07/msg00670.html
Philippe highlighted that you might have some reservations about
this patch series, which I think is currently the main blocker for
this patch getting approval.
In the thread started here:
https://sourceware.org/ml/gdb-patches/2018-05/msg00299.html
and ending here:
https://sourceware.org/ml/gdb-patches/2018-06/msg00142.html
you did review and approve one of the original patch variants, which
is most like the "level" variant of the patch submitted here:
https://sourceware.org/ml/gdb-patches/2018-08/msg00337.html
I would be really grateful if you could let me know your current
thoughts on this patch, are you happy to have the "level" variant
merged based on your previous approval, or has you position changed?
Thanks.
Philippe:
Thanks for the review and feedback in:
https://sourceware.org/ml/gdb-patches/2018-08/msg00349.html
I wasn't sure if the second part of you mail was suggesting that
those instances of level vs number needed to be resolved as part of
this patch for you to be happy, or if this was just identifying what
we should clean up if/when this patch is merged. Additional clarity
here would help me figure out my next steps for getting this patch
merged.
Thanks.
Many thanks to everyone who's taken time to review this for me.
Thanks,
Andrew
