Hi All,
I took a few moments away from what I really must be doing to try out
an earlier version of the patch. There are quite a few CRs in the
patch and the third chunk in gcc.c was rejected, although I cannot see
why. I made a change to scanner.c to prevent the segfault that results
from not having the pre-include file in the right directory - see
attached.
Everything works fine with the testcases and a slightly evolved
version shows reasonable speed-ups:
program test_overloaded_intrinsic
real(4) :: x4(3200), y4(3200, 10000)
real(8) :: x8(3200), y8(3200)
do i = 1,10000
y4(:,i) = cos(x4)
y4(:,i) = x4*y4(:,i)
y4(:,i) = sqrt(y4(:,i))
end do
print *, y4(1,1)
end
Disappointingly, though, one of the worst cases in
https://www.fortran.uk/fortran-compiler-comparisons/ of a big
difference between gfortran and ifort with vectorization,
mp_prop_design.f90, doesn't seem to pick up any of the vectorization
opportunities, even though it is peppered with trig functions. Should
I be expecting this? Yes, I did add the other trig functions to the
pre-include file :-)
Best regards and thanks for taking care of this
Paul
