This moves the gdb-specific obstack code -- both extensions like obconcat and obstack_strdup, and things like auto_obstack -- to gdbsupport.

/* This struct is designed to store data from using directives. It
|
|
says that names from namespace IMPORT_SRC should be visible within
|
|
namespace IMPORT_DEST. These form a linked list; NEXT is the next
|
|
element of the list. If the imported namespace or declaration has
|
|
been aliased within the IMPORT_DEST namespace, ALIAS is set to a
|
|
string representing the alias. Otherwise, ALIAS is NULL.
|
|
DECLARATION is the name of the imported declaration, if this import
|
|
statement represents one. Otherwise DECLARATION is NULL and this
|
|
import statement represents a namespace.
|
|
|
|
C++: using namespace A;
|
|
Fortran: use A
|
|
import_src = "A"
|
|
import_dest = local scope of the import statement even such as ""
|

alias = NULL

|
|
import_dest = local scope of the import statement even such as ""
|
|
alias = NULL
|
|
declaration = "x"
|
|
excludes = NULL
|
|
The declaration will get imported as import_dest::x.
|
|
|
|
C++ has no way to import all names except those listed ones.
|
|
Fortran: use A, localname => x
|
|
import_src = "A"
|
|
import_dest = local scope of the import statement even such as ""

|
|
import_dest = local scope of the import statement even such as ""
|
|
alias = NULL
|
|
declaration = NULL
|
|
excludes = ["x"]
|
|
All the entries of A get imported except of "x". "x" gets imported as
|
|
"localname". "x" is not defined as a local name by this statement.
|
|
|
|
C++: namespace LOCALNS = A;
|
|
Fortran has no way to address non-local namespace/module.
|
|
import_src = "A"
|
|
import_dest = local scope of the import statement even such as ""
|
|
alias = "LOCALNS"
|
|
declaration = NULL
|
|
excludes = NULL
|
|
The namespace will get imported as the import_dest::LOCALNS
|
|
namespace.
|
|
|
|
C++ cannot express it, it would be something like: using localname
|
|
= A::x;
|
|
Fortran: use A, only localname => x
|
|
import_src = "A"
|
|
import_dest = local scope of the import statement even such as ""
|
|
alias = "localname"
|
|
declaration = "x"
|
|
excludes = NULL
|
|
The declaration will get imported as localname or
|
|
`import_dest`localname. */
