Bug ID: 97063
Summary: [ MATMUL intrinsic] The value of result is wrong when
vector (step size is negative) * matrix
Product: gcc
Version: 10.1.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: xin.liu@compiler-dev.com
Target Milestone: ---
Consider the following Fortran program:
program p
implicit none
real(kind=16), dimension(6) :: arr1
real(kind=16), dimension(6, 10) :: arr2
real(kind=16), dimension(10) :: arr3, arr6
real(kind=16), dimension(3) :: arr4
real(kind=16), dimension(3, 10) :: arr5
integer :: i, j
data arr1 /0.0_16, 1.0_16, 2.0_16, 3.0_16, 4.0_16, 5.0_16/
do i = 1, 6
do j = 1,10
arr2(i, j) = (i + j) * 1.0_16
end do
end do
write(*,*) "--arr3--:"
arr3 = matmul(arr1(5:1:-2),arr2(5:1:-2, :))
write(*,'(5F5.1)') arr3
write(*,*) "--arr4--:"
arr4 = arr1(5:1:-2)
write(*,'(5F5.1)') arr4
write(*,*) "--arr6--:"
arr6 = matmul(arr4, arr2(5:1:-2, :))
write(*,'(5F5.1)') arr6
end program
Compiled with gfortran 10.1.0, the program prints:
--arr3--:
44.0 53.0 62.0 71.0 80.0
89.0 98.0107.0116.0125.0
--arr4--:
4.0 2.0 0.0
--arr6--:
32.0 38.0 44.0 50.0 56.0
62.0 68.0 74.0 80.0 86.0
As you can see,the value of arr3 is differnet with arr6.

Confirmed. This happens with all real kinds, not only kind=16.
The output is easier to read when replacing
write(*,'(5F5.1)') arr3
by
write(*,'(10F5.1)') arr3
etc.

Interestingly, the bug "disappears" if frontend optimization is enabled
(-ffrontend-optimize), thus at all optimizations that enable it.

It could be we need to fix in the runtime library. I have not looked to closely
yet but it would be best I think if the front-end did the necessary
transforming. The code is probably there already to do it.

--- Comment #4 from anlauf at gcc dot gnu.org ---
Having looked at the tree-dump, I am not sure if it is a FE or a library issue.
I appears that the negative stride miscalculates the base or offset of
the array probably by one:
program p
implicit none
integer :: i, j
real, dimension(6) :: arr1 = [(i,i=0,5)]
real, dimension(6,10) :: arr2 = reshape ([(((i+j),i=0,5),j=0,9)],[6,10])
real, dimension(10) :: arr3, arr6
real, dimension(3) :: arr4
arr4 = arr1(5:1:-2)
write(*,*) "--arr6--:"
arr6 = matmul (arr4 , arr2(5:1:-2, :))
write(*,'(10F6.1)') arr6
arr4 = arr1(6:2:-2)
write(*,*) "--arr6-- (with arr1 off by one):"
arr6 = matmul (arr4 , arr2(5:1:-2, :))
write(*,'(10F6.1)') arr6
arr3 = matmul (arr1(5:1:-2), arr2(5:1:-2, :))
write(*,*) "--arr3--:"
write(*,'(10F6.1)') arr3
end program
This prints:
--arr6--:
20.0 26.0 32.0 38.0 44.0 50.0 56.0 62.0 68.0 74.0
--arr6-- (with arr1 off by one):
26.0 35.0 44.0 53.0 62.0 71.0 80.0 89.0 98.0 107.0
--arr3--:
26.0 35.0 44.0 53.0 62.0 71.0 80.0 89.0 98.0 107.0

PR libfortran/97063 - Wrong result for vector (step size is negative) *
matrix
The MATMUL intrinsic provided a wrong result for rank-1 times rank-2 array
when a negative stride was used for addressing the elements of the rank-1
array, because a check on strides was erroneously placed before the check
on the rank. Interchange order of checks.
