The code introduces the symbol as an static alias of function.
I.e. something like

void foo (void) { }
void foo.localalias (void) __attribute__ ((alias "foo"));

Can this be latent bug in HPPA backend not handling well aliases like this?
(this was indeed an issue on AIX).

I wouldn't be surprised.

I don't have assembler output or preprocessed source yet.  There is  
some alias
support in gas for HP-UX but I believe it may not work when we have a  
call using
a function descriptor (plabel).

On AIX David fixed the output machinery so the aliases now go well even for
descriptors.  There local calls don't use them.  Do you think you can take
a look what is needed for HPUX?  We may just add target machinery to disable
local aliases on targets that can't do aliases.  I hoped that the targets
either do not have runtime interposition in dynamic libraries or they do
have working notion of alias.

Thanks,
Honza

The PA-RISC HP-UX linker interposes import and export stubs in dynamic  
libraries.
Whether there is a working notion of alias is somewhat unclear and  
involves digging
into the linker code.  The HP assembler doesn't support aliases.   
There is some
support in gas.

I will try to look at the testcase assembler code tonight.

OK, perhaps we want to disable local aliases then.
#if !defined (ASM_OUTPUT_DEF)
# if !defined(ASM_OUTPUT_WEAK_ALIAS) && !defined (ASM_WEAKEN_DECL)
      error_at (DECL_SOURCE_LOCATION (decl),
                "alias definitions not supported in this configuration");
      return;
# else
      if (!DECL_WEAK (decl))
        {
          if (lookup_attribute ("ifunc", DECL_ATTRIBUTES (decl)))
            error_at (DECL_SOURCE_LOCATION (decl),
                      "ifunc is not supported in this configuration");
          else
            error_at (DECL_SOURCE_LOCATION (decl),
                      "only weak aliases are supported in this configuration");
          return;
        }
# endif
#endif

perhaps we want to simply check for ASM_OUTPUT_DEF in symtab and refuse
to use local aliases then?  I think the other macros alow only weak aliases.

The attached patch gets past the error.  Testing.

--- Comment #10 from Jan Hubicka <hubicka at gcc dot gnu.org> ---
OK,
I made similar patch on trip to Pisa.  I think correct is to return NULL and
make callers handle it - it does not make sense to consider non-local label to
be local alias.  I will test it and commit
