Hi Steve,
I don't think you should send mail directly to gcc-bugs ("gcc-bugs is
a relatively high volume list with mails from our Bugzilla bug-
tracking system"). I think, apart from Andrew, noone's subscribed to
it :)
FAIL: gfortran.dg/ltrans-7.f90 -O scan-tree-dump-times ltrans
"transformed loop" 1
Sounds like a target-specific issue with -ftree-loop-linear.
According to gcc-testresults, it is seen on i386-freebsd and i386-
netbsd. Similar C failures happen on i386-rtems. Maybe the loop can
be transformed only for processors later than i386? In any case, this
most probably isn't a Fortran issue.
Daniel, Zdenek, I assume you being "linear loop transforms" and "loop
infrastructure" maintainers means you're the right persons to CC, so
there you go.
