Iain,
I seem to still have issues. I downloaded 9.2.0 this morning and built it with:
$ ../gcc-9.2.0/configure
--prefix=/Users/mathomp4/installed/Core/gcc-gfortran/9.2.0
--enable-languages=c,c++,fortran --

A third problem: Zero-trip do loops are warned about.
program main
implicit none
integer :: i
real :: a(2)
do i=1,3,-1
a(i) = 2.
end do
print *,a
end program main
gets

--- Comment #3 from Segher Boessenkool ---
There are quite many different cases to test, and many *more* do not currently
generate the wanted code because it isn't optimised properly on gimple level,
and that makes it hard to test the RTL / targe

I think part of the problem with the current or_comparison optimization is that
it relies on invert_tree_comparison in many cases, and that doesn't really work
for floating point (and we handle the unsafe flags
