Still works on x86_64, so it's a target issue.

Nevertheless a regression.

There really has not been any rs6000 changes lately so I am going to say
middle-end until I get to look into it on powerpc-linux-gnu.

------- Comment #6 from dominiq at lps dot ens dot fr 2007-02-27 15:36 -------
I don't know if this reduced test account for all the problem, but it exhibits
at least one bug:
module perdida_m
implicit none
contains
subroutine perdida (dt, strain_tensor)
real (kind = 8), intent(in) :: dt
real (kind = 8), dimension(:,:), intent(in) :: strain_tensor
end subroutine perdida
end module perdida_m
program iztaccihuatl
use perdida_m
implicit none
real (kind = 8) :: dt, time, coefficient
real (kind = 8), dimension(3,3,10) :: strain_tensor
dt = 5.555555555555556D-006
strain_tensor = 0.0_8
time = dt
coefficient = sin(time)
print *, coefficient
coefficient = cos(time)
call perdida (dt, strain_tensor(:,:,1))
end program iztaccihuatl
gives
1.947453947074031E-314
If I comment the line 'call perdida (dt, strain_tensor(:,:,1))', I get
5.555555555526978E-006
As far as I can tell, all the ingredients in this test case are necessary to
trigger the bug.

Thanks to Richard Guenther, the bug seems to be fixed (hopefully in the
20070316 snapshot):
see PR31161 for details.
I'll comment in another PR about the corresponding "optimization" (too late to
do it tonight).

Never confirmed, and reported says the bug seems to be fixed.
If the bug is still there, please re-open this PR.
