For the missing inquiry function, see PR 40569.

Do not forget to update intrinsic.texi!

Missing are the following integer arrays/scalars:


CHARACTER_KINDS
  [ 1, 4 ]

INTEGER_KINDS
  [ 1, 2, 4 ...]

LOGICAL_KINDS
  [ 1, 2, 4, ...]

REAL_KINDS
  [ 4, 8, ... ]


IO_INQUIRE_INTERNAL_UNIT
  some positive number which cannot appear for any
  other error as value for IOSTAT=

STAT_STOPPED_IMAGE
  positive, /= IO_INQUIRE_INTERNAL_UNIT
  Different from other STAT= values which appear for
  STAT= in ALLOCATE/DEALLOCATE and in
  SYNC ALL/IMAGES/MEMORY.

Draft patch for kinds

Some constants such as GFC_STAT_STOPPED_IMAGE have been added as part of the
coarray work. Besides the compiler_*() functions (PR 40569), the coarray LOCK_*
types are missing.

To this patch: It adds support for the *_kinds parameter arrays.
TODO:

a) It does not fully work, while the following is OK
   print *, (real_kinds), shape(real_kinds)
without (), it gives a linker error:
   print *, real_kinds
namely: undefined reference to `__iso_fortran_env_MOD_integer_kinds'

b) The .texi changes are missing

See PR 44856 for the reason why it fails for some expressions.

New draft patch

New draft patch.

New: Documentation added; "REAL_KINDS" and "REAL_KINDS(1)" works now.

TODO
- The test case in the file, i.e. "REAL(REAL_KINDS(1))" fails with "Error:
Constant expression required"
- Include attachment 21126 as test case

------- Comment #5 from burnus at gcc dot gnu dot org  2010-09-06 17:55 -------
More failures:

use iso_fortran_env
integer :: i
print *, shape(real_kinds(1))  ! should be rejected (scalar)
i = real_kinds(1)              ! ICE
end

Thus, the FE has problems if one takes a REF of an EXPR_ARRAY, i.e. the shape
does not get updated.
