No need for a temp here:
SUBROUTINE S1(a,i,j,k,m)
INTEGER :: a(3,6)
a(1:3,m)=(/i,j,k/)

------- Comment #1 from jv244 at cam dot ac dot uk 2008-11-14 09:07 -------
I guess this one is similar enough to put here as well:
SUBROUTINE S1(a,i,j,k,m)
INTEGER :: a(3,6)
write(6,*) ALL(a(1:3,m).EQ.(/i,j,k/))
END

similar enough to make this one depend on PR36935. I think the testcases here
(certainly comment #1), are more difficult.

4.7 still generates the temporaries. Looks like the middle end deals with this
rather well for the #c0 testcase, but not #c1.
