--- Comment #13 from Tobias Burnus <burnus at gcc dot gnu.org> 2010-12-09 14:15:13 UTC --- Another reason for the Tonto failure could be PR 45777. I have now looked through the TRANSPOSEs of Tonto (cf. comment 11) - and I did not see anything which looks as if it could go wrong. I think it would help if someone with access to SPEC CPU 2006 could debug this further - and tell which version of Tonto is included in CPU 2006. I have looked the the source of the latest (2.3.1) - maybe the crucial code is an an earlier version. The issue of comment 12 does not seem to apply to Tonto - but it should be fixed nevertheless.
