Target Milestone: ---
I know strange params, but still:
$ cat unpack.f90
type i4_t
integer v
end type
type(i4_t), dimension(3,3) :: bt4
if (any (bt4v .ne. reshape ((/1, 2, 0, 3, 1, 0, 0, 0, 4/), (/3, 3/)))) bt4%v
= 1
if (any (bt4%v .ne. reshape ((/0, 2, 0, 3, 0, 0, 0, 0, 4/), (/3, 3/)))) STOP
end
$ gfortran unpack.f90 --param=max-completely-peeled-insns=0
-fno-tree-dominator-opts --param=unroll-jam-min-percent=0 -fno-tree-ch -O3 -c
during GIMPLE pass: unrolljam
