--- Comment #6 from Kazumoto Kojima <kkojima at gcc dot gnu.org> 2012-06-12 00:05:05 UTC --- I thought that -pg and -fomit-frame-pointer are always incompatible. Agree with the possible issues for old unwinders. I've forgotten that sh coff targets went away. Then, removing that line might be enough. I'd like to approve any patches for this PR :-) It should be backported to the release branches, because this is a 4.6/4.7/4.8 regression from 4.5, AFAIK.
