/* Return true when DECL can be referenced from current unit.
|
2012-05-19 11:49:47 +02:00
|
|
|
FROM_DECL (if non-null) specify constructor of variable DECL was taken from.
|
|
|
|
We can get declarations that are not possible to reference for various
|
|
|
|
reasons:
|
2010-09-18 23:25:29 +02:00
|
|
|
|
|
|
|
1) When analyzing C++ virtual tables.
|
|
|
|
C++ virtual tables do have known constructors even
|
|
|
|
when they are keyed to other compilation unit.
|
|
|
|
Those tables can contain pointers to methods and vars
|
|
|
|
in other units. Those methods have both STATIC and EXTERNAL
|
|
|
|
set.
|
|
|
|
2) In WHOPR mode devirtualization might lead to reference
|
|
|
|
to method that was partitioned elsehwere.
|
|
|
|
In this case we have static VAR_DECL or FUNCTION_DECL
|
|
|
|
that has no corresponding callgraph/varpool node
|
2010-10-04 22:59:07 +02:00
|
|
|
declaring the body.
|
|
|
|
3) COMDAT functions referred by external vtables that
|
2013-11-06 15:37:46 +01:00
|
|
|
we devirtualize only during final compilation stage.
|
2010-10-04 22:59:07 +02:00
|
|
|
At this time we already decided that we will not output
|
|
|
|
the function body and thus we can't reference the symbol
|
|
|
|
directly. */

it may be tempting to not necessarily give up because the copy will be

output elsewhere when corresponding vtable is output.

This is however not possible - ABI specify that COMDATs are output in

units where they are used and when the other unit was compiled with LTO

it is possible that vtable was kept public while the function itself
