Transformational intrinsics, done are:
 * all, any, count
 * product, sum
 * dot_product, matmul, transpose
 * pack, unpack, spread

Left:
 * maxloc, minloc
 * maxval, minval (generic case)
 * cshift, eoshift

While at it, see also PR29600 (kind arguments) and PR36313 (character type).

Earlier this year, I was working on the cshift/eoshift, but I strongly believe
that the linear list that builds the constructor must be replaced with splay
trees before this can be implemented somewhat efficiently.

I think what is left in pr29962 is a duplicate of this one.

If the error message you refer to is

> Error: transformational intrinsic 'cshift' at (1) is not permitted in an
> initialization expression

then yes.

MAXLOC and MINLOC are also missing (see pr25104).

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_*?
