! Check that LBOUND/UBOUND/SIZE/SHAPE of array-expressions get simplified
! in certain cases.
! There should no array-temporaries warnings pop up, as this means that
! the intrinsic call has not been properly simplified.
! Contributed by Daniel Kraft, d@domob.eu.
PROGRAM main
IMPLICIT NONE
! Some explicitely shaped arrays and allocatable ones.
INTEGER :: a(2, 3), b(0:1, 4:6)
INTEGER, ALLOCATABLE :: x(:, :), y(:, :)
! Allocate to matching sizes and initialize.
ALLOCATE (x(-1:0, -3:-1), y(11:12, 3))
a = 0
b = 1
x = 2
y = 3
! Run the checks. This should be simplified without array temporaries,
! and additionally correct (of course).
! Shape of expressions known at compile-time.
IF (ANY (LBOUND (a + b) /= 1)) STOP 1
IF (ANY (UBOUND (2 * b) /= (/ 2, 3 /))) STOP 2
IF (ANY (SHAPE (- b) /= (/ 2, 3 /))) STOP 3
IF (SIZE (a ** 2) /= 6) STOP 1
! Shape unknown at compile-time.
IF (ANY (LBOUND (x + y) /= 1)) STOP 4
IF (SIZE (x ** 2) /= 6) STOP 5
! Unfortunately, the array-version of UBOUND and SHAPE keep generating
! temporary arrays for their results (not for the operation). Thus we
! can not check SHAPE in this case and do UBOUND in the single-dimension
! version.
IF (UBOUND (2 * y, 1) /= 2 .OR. UBOUND (2 * y, 2) /= 3) STOP 6
!IF (ANY (SHAPE (- y) /= (/ 2, 3 /))) STOP 7
