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.
