            Bug ID: 58773
           Summary: alpha-dec-vms problems with "*INTERNAL*" in assembly
                    (with current GNU as/ld)
           Product: gcc
           Version: 4.8.2
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: bootstrap
          Assignee: unassigned at gcc dot gnu.org
          Reporter: jay.krell at cornell dot edu

This was probably with an older GNU ld/as:

This is similar with in-tree current GNU as/ld/binutils:


 /obj/gcc.1/./gcc/as -o array_type_info.obj

symbol for global function '_ZN10__cxxabiv117__array_type_infoD1Ev'


The assembly in question:

    .quad    _ZN10__cxxabiv117__array_type_infoC1EPKc *INTERNAL* 
    .quad    _ZN10__cxxabiv117__array_type_infoD1Ev *INTERNAL* 

*internal* comes from gcc/cp/mangle.c.

I tried outputing just a space instead but that failed also:

I suppose what I should do is compile this for some other target and see what I
get.
