Bug ID: 102003
Summary: [PDT] Length of character component not simplified
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: anlauf at gcc dot gnu.org
Target Milestone: ---
We should be able to simplify at compile time the following code:
type pdt(n)
integer, len :: n = 8
character(len=n) :: c
end type pdt
type(pdt(42)) :: p
integer, parameter :: m = len (p% c) ! rejected
print *, len (p% c) == 42 ! works, but not simplified
end
Instead we currently get:
foo.f90:6:27:
6 | integer, parameter :: m = len (p% c) ! rejected
| 1
Error: Cannot convert UNKNOWN to INTEGER(4) at (1)
(The code is accepted by Intel.)
