RE: c++/4135: Unable to link: "non-virtual thunk" in HPUX11 and AIX (gcc-3.0.1)

["Gard, Torbjorn" <torbjorn dot gard at streamserve dot com>]

Hi

Yes the patch solves the problem in gcc-3.0.1 for these architectures:
AIX 4.2.0,4.3.3/HPUX 10.20,11.0/Solaris 2.6.

I have gcc-3.0.2 in Alpha-OSF4.0d without the patch and this works also. I
was unable to
compile 3.0.1 on this platform, so I can not say if the problem already is
solved
in 3.0.2.

State-Changed-Why:
    Does the patch you provided in PR 3536 solve
    this problem?
    
     Hello,
     
     The thunks were actually generated and found in the object files but
they
     were not public so linking failed. Adding the three lower lines to the
     function make_thunk() in /gcc/cp/method.c seems solve problem 3536.
     
     Line 361:
     
           /* And neither is it a clone.  */
           DECL_CLONED_FUNCTION (thunk) = NULL_TREE;
           DECL_EXTERNAL (thunk) = 1;
     
     +     /* Make the thunk public unless it is for a destructor */
     +     if (!DECL_DESTRUCTOR_P (func_decl))
     +      TREE_PUBLIC (thunk) = 1;
