--- Comment #4 from Richard Biener <rguenth at gcc dot gnu.org> ---
Runtime testcase (not sure if sufficient ...). Andre - can you verify it
passes runtime testing with the patch on HW that supports the complex mul?
complex function cdcdot(n, cx)
implicit none
integer :: n, i, kx
complex :: cx(*)
double precision :: dsdotr, dsdoti, dt1, dt3
kx = 1
do i = 1, n
dt1 = real(cx(kx))
dt3 = aimag(cx(kx))
dsdotr = dsdotr + dt1 * 2 - dt3 * 2
dsdoti = dsdoti + dt1 * 2 + dt3 * 2
kx = kx + 1
end do
cdcdot = cmplx(real(dsdotr), real(dsdoti))
return
end function cdcdot
program test
implicit none
complex :: cx(100), ct, cdcdot
integer :: i
do i = 1, 100
cx(i) = cmplx(2*i, i)
end do
ct = cdcdot (100, cx)
if (ct.ne.cmplx(10100.0000,30300.0000)) call abort
end
