[Bug c++/26195] pragma interface no longer handles explicit names

["zak at transversal dot com" <gcc-bugzilla at gcc dot gnu dot org>]

------- Comment #3 from zak at transversal dot com  2006-02-10 17:05 -------
After making the change suggested in comment #1, the following test case
demonstrates the problem mentioned in comment #2.

$ g++ -Wall -pedantic -I. foo.cc && nm -A foo.o
[no output]

If you switch the name in the pragma implementation directive to "dir2/foo.h",
then the implementations of *both* headers are output:
foo.o:         U __gxx_personality_v0
foo.o:00000000 W _ZN2A1C1Ev
foo.o:00000000 W _ZN2A1C2Ev
foo.o:00000000 W _ZN2A2C1Ev
foo.o:00000000 W _ZN2A2C2Ev


In 3.4.5, the implementation of the header with the matching pragma interface
directive is correctly output in each case.


I'm currently testing a patch that, in addition to the above change, removes
all the uses of lbasename in this context (two in decl.c, one in lex.c and one
in semantics.c, all in code specific to handling #pragma interface and
introduced in revision 87786).



// foo.cc
#pragma implementation "dir1/foo.h"
#include "dir1/foo.h"


// dir1/foo.h
#pragma interface "dir1/foo.h"
#include "dir2/foo.h"

struct A1
{
        A1() { }
};


// dir2/foo.h
#pragma interface "dir2/foo.h"

struct A2
{
        A2() { }
};
