According to amodra's analysis, "-mno-sched-prolog breaks function
parameter debug location lists" on powerpc.

I have not yet tried to reproduce this with gcc-vta/rawhide yet,
but it impacts F11 for sure, so a backport of the patch would be
appreciated.

First of all, the kernel shouldn't be using such options.  The comment in kernel's Makefile talks about working around some gcc bug with -fno-omit-frame-pointer, has that bug even been filed to gcc?

Maybe, but if the patch now committed to gcc mainline can be
backported, we can fight that battle another time.
Comment 3 Jakub Jelinek 2009-09-24 06:56:07 UTC 
Fixed in gcc-4.4.1-16.
