If one runs the attached Fortran 2008 program with GCC 4.4 and default options
one gets:
Error: 'x' argument of 'acos' intrinsic at (1) must be REAL
for the complex arguments, which is OK.
However, using -std=f2003 one gets additionally warnings of the kind:
r4 = asinh(r4)
1
Error: Can't convert UNKNOWN to REAL(4) at (1)
Which are completely bogus. (The attached file is a testcase for the complex
acos etc. implementation for PR 33197.)

------- Comment #2 from burnus at gcc dot gnu dot org 2009-07-22 08:11 -------
The error comes about since with -std=2003, asinh is not an available
intrinsic. Solution for the testcase/attached file: "-fall-intrinsics" or
removal of a(sin,cos,tan)h - which were added only with F2008 though the REAL
version was a GNU extension before.
* * *
Current result (4.4, 4.5):
Error: Can't convert UNKNOWN to REAL(4) at (1)
Expected: A better error message such as gfortran 4.2 had ["Regression"]:
Error: Function 'asinh' at (1) has no IMPLICIT type
If one enables implicit typing (or explicitly types the function), one gets the
expected:
undefined reference to `asinh_'
And if one uses "abcd", one gets the old 4.2 error. I tried to trace the
problem - with out success so far. At least the function gfc_is_intrinsic seems
to work.

------- Comment #3 from burnus at gcc dot gnu dot org 2009-07-22 08:38 -------
Found it: In "resolve_function" one has:
switch (procedure_kind (sym))
{
case PTYPE_GENERIC: ...
case PTYPE_SPECIFIC: ...
case PTYPE_UNKNOWN: ...
The correct branch would be "PTYPE_UNKNOWN", which correctly give the error.
But "procedure_kind" calls "generic_sym", which in turns calls:
if (sym->attr.generic ||
(sym->attr.intrinsic && gfc_generic_intrinsic (sym->name)))
return 1;
The gfc_generic_intrinsic justs checks:
sym = gfc_find_function (name);
return (sym == NULL) ? 0 : sym->generic;
Expected: In the latter, one needs to add a
gfc_check_intrinsic_standard (sym, NULL, true,
Analogously for: gfc_specific_intrinsic.

------- Comment #4 from burnus at gcc dot gnu dot org 2009-07-23 08:52 -------
Hmm, to early, the gfc_*_intrinsic are not called, unless attr.intrinsic is
set. The but the issue is indeed that they are regarded as PTYPE_SPECIFIC and
not as PTYPE_UNKNOWN, as a printf in resolve_function shows - the question is
only why.
* * *
The following program causes an ICE in gfc_typenode_for_spec due to BT_UNKNOWN
-- and no warning/error is shown before ("gfortran -std=f95"):
implicit none
real :: r
r = 0.4
print *, atanh(r)
end

Both the bogus error and the ICE (also with std=f95) are still there. The PR
should be marked NEW.
