[Bug ld/246] New: Can't mix comdat group with linkonce section

[hjl at lucon dot org]

If gcc is modified to use comdat group instead of linkonce section. It
may generate code like:

        .section        .text,"axG",@progbits,.__i686.get_pc_thunk.bx,comdat
.globl __i686.get_pc_thunk.bx
        .hidden __i686.get_pc_thunk.bx
        .type   __i686.get_pc_thunk.bx, @function
__i686.get_pc_thunk.bx:

instead of

        .section        .gnu.linkonce.t.__i686.get_pc_thunk.bx,"ax",@progbits
.globl __i686.get_pc_thunk.bx
        .hidden __i686.get_pc_thunk.bx
        .type   __i686.get_pc_thunk.bx,@function
__i686.get_pc_thunk.bx:

The new gcc should work with the libraris compiled with the
oldler gcc. But the current linker doesn't support mixing
comdat group with linkonce section. I think the linker should
match a member of a COMDAT group with a single member with a
linkonce section.
