I agree that it is reasonable to defer the handling of arrays as
components of derived types, and recommend to do the following:
- replace "&& gfc_is_simply_contiguous (expr, true, f

Hi Prathamesh,

It seems that component references are not currently handled even for static
size arrays ?
For eg:
subroutine test_dt (dt, y)
implicit none
real :: y (10, 20, 30)
type t
real :: x(10, 20, 30)
end type t

Hi Prathamesh,

Hi,
The attached patch lowers zeroing array assignment to memset for allocatable
arrays.
For example:
subroutine test(z, n)
implicit none
integer :: n
real(4), allocatable :: z(:,:,:)
allocate(z(n, 8192, 2048
e patch significantly improves speedup for an internal Fortran application on
AArch64 -mcpu=grace (and potentially on other AArch64 cores too).
Bootstrapped+tested on aarch64-linux-gnu.
Does the patch look OK to commit ?

Thanks,
