! Program to test elemental functions. program test_elemental implicit none integer(kind = 4), dimension (2, 4) :: a integer(kind = 4), dimension (2, 4) :: b integer(kind = 8), dimension(2) :: c a = reshape ((/2, 3, 4, 5, 6, 7, 8, 9/), (/2, 4/)) b = 0 b(2, :) = e_fn (a(1, :), 1) if (any (b .ne. reshape ((/0, 1, 0, 3, 0, 5, 0, 7/), (/2, 4/)))) call abort a = e_fn (a(:, 4:1:-1), 1 + b) if (any (a .ne. reshape ((/7, 7, 5, 3, 3, -1, 1, -5/), (/2, 4/)))) call abort ! This tests intrinsic elemental conversion functions. c = 2 * a(1, 1) if (any (c .ne. 14)) call abort ! This triggered bug due to building ss chains in the wrong order. b = 0; a = a - e_fn (a, b) if (any (a .ne. 0)) call abort ! Check expressions involving constants a = e_fn (b + 1, 1) if (any (a .ne. 0)) call abort contains elemental integer function e_fn (p, q) integer, intent(in) :: p, q e_fn = p - q end function end program
