I don't remember any fallout from the final patch no. My reticence for a
backport was due to

* adding a new target hook
* patching functions to generate PIC sequences.

I'm not sure how much these functions have changed over the year, I suspect not
much and the rest of the patch should be fairly self contained. I would not
expect too much work to backport the change itself by someone else (I am not in
a position to do the work myself), but whether such a change would be
acceptable on a stable branch is up to the relevant maintainer.

[Bug other/56036] New: Wrong indentation in multiple -O options explaination

[robotux at celest dot fr]

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=56036



 Bug #: 56036

   Summary: Wrong indentation in multiple -O options explaination

Classification: Unclassified

   Product: gcc

   Version: 4.8.0

Status: UNCONFIRMED

  Severity: trivial

  Priority: P3

 Component: other

AssignedTo: unassig...@gcc.gnu.org

ReportedBy: robo...@celest.fr





Hi there,



the indentation in the manual describing what happens when multiple -O options

are specified on the command line is wrong. It's the same as the last item

(-Og) so it seems it only applies to that last options instead of being related

to -O options in general. Here is a patch to fix that, made against trunk

r195301.



Best regards,



Thomas Preud'homme

Indeed, not anymore, sorry.
