While playing with modifications of PR4581, I tried
module m
implicit none
type t
integer :: i
end type t
type(t), dimension(2), parameter :: a1 = (/ t(1), t(2) /)
type(t), dimension(2), parameter :: d = cshift ( a1, 1 )

type(t), dimension(2), parameter :: d = cshift ( a1, 1 )

Error: transformational intrinsic 'cshift' at (1) is not permitted in an
initialization expression
The F2003 standard says:
(5) A reference to a transformational standard intrinsic function other than
NULL, where each argument is an initialization expression,
and the F2008 version adds:
(6) a reference to a transformational standard intrinsic function other than
COMMAND ARGUMENT -COUNT, NULL, NUM IMAGES, THIS IMAGE, where each argument is a
constant expression,
This is fixed by the following patch:

Hence, with your patch they will be accepted, but you'd end up with wrong code at the end, as the functions are not properly simplified and thus not constant. I have seen that, and also in gcc/fortran/simplify.c /* FIXME: Returning here avoids a regression in array_simplify_1.f90. Replace NULL with gcc_unreachable() after implementing gfc_simplify_cshift(). */ Am I correct to understand that the current situation (i.e. the error message) is a temporary fix for some missing gfc_simplify_*? -- dominiq at lps dot ens dot fr changed: What|Removed |Added Summary|CSHIFT and EOSHIFT are not |[F2003] Missing |in the trans_func_f2003 list|transformational intrinsic ||in the trans_func_f2003 list http://gcc.gnu.org/bugzilla/show_bug.cgi?id=45689

[Bug fortran/45624] Division by zero compiler error
--- Comment #4 from dominiq at lps dot ens dot fr 2010-09-09 23:20 --- You can use the option -fno-range-check. However, the code itself and the sentence since I want to protect this variable in comment #3 let me suspect that you have not understood what PARAMETER is for: a variable with the PARAMETER attribute is an alias for its value and exists only during the compilation. What you seem to want is the attribute PROTECTED, i.e. a variable that can be changed only in a specified place as in (F2003 standard draft): An example of the PROTECTED attribute: MODULE temperature REAL, PROTECTED :: temp_c, temp_f CONTAINS SUBROUTINE set_temperature_c(c) REAL, INTENT(IN) :: c temp_c = c temp_f = temp_c*(9.0/5.0) + 32 END SUBROUTINE END MODULE The PROTECTED attribute ensures that the variables temp_c and temp_f cannot be modi ed other than via the set_temperature_c procedure, thus keeping them consistent with each other. The PROTECTED attribute is a f2003 addition, implemented at least from gfortran 4.4. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=45624

[Bug fortran/45159] Unnecessary temporaries
--- Comment #19 from dominiq at lps dot ens dot fr 2010-08-10 12:00 --- (In reply to comment #18) Although it is probably better set the stride during resolution. Probably. A few comments before leaving for ten days without access to the net. (1) I think all the changes done recently to avoid unneeded temporaries can be extended by reversing the loops. (2) The following code generates an unneeded temporary: integer, parameter :: n = 10 integer :: i integer :: a(0:n+1) = (/(i, i =0, n), 0/) a(:6:2) = a(::3) print *, a end It is in the class abs(r_stride)max(0,abs(l_stride)) for which there is no need for temporary if l_startr_start+r_stride for r_stridemax(0,l_stride) or l_startr_start+r_stride for r_stridemin(0,l_stride) If I am not mistaken, this is the last case for which one can conclude for any size of the sections. (I have done the proof on the back of an envelope that I cannot find right now.) For all the remaining cases it exists some set of triplets for which there is a dependency even if for some others there is none (depending upon the dependent indices are inside or not of the actual range). Although this can be implemented, I seriously doubt it is worth the pain. (3) I think the coverage for missing temporaries is rather limited right now and I am planning to write some torture test(s) to improve this situation. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=45159
