It still isn't right:

bash-3.2$ cat
/export/gnu/src/binutils/binutils/binutils/testsuite/binutils-all/group.s
        .section .text.foo,"axG",%progbits,foo_group,comdat
        .global foo
foo:
        .word 0
        .section .data.foo,"awG",%progbits,foo_group,comdat
        .global bar
bar:
        .word 0
bash-3.2$ cat
/export/gnu/src/binutils/binutils/binutils/testsuite/binutils-all/group-2.s
        .section .text.foo,"axG",%progbits,.text.foo,comdat
        .global foo2
foo2:
        .word 0
        .section .data.bar,"awG",%progbits,.text.foo,comdat
        .global bar2
bar2:
        .word 0
bash-3.2$ gcc -c
/export/gnu/src/binutils/binutils/binutils/testsuite/binutils-all/group.s
/export/gnu/src/binutils/binutils/binutils/testsuite/binutils-all/group-2.s
bash-3.2$ ./ld-new -r group.o group-2.o
bash-3.2$ readelf -g group-2.o

COMDAT group section [    1] `.group' [.text.foo] contains 2 sections:
   [Index]    Name
   [    5]   .text.foo
   [    6]   .data.bar
bash-3.2$ readelf -g a.out 

COMDAT group section [    1] `foo_group' [foo_group] contains 2 sections:
   [Index]    Name
   [    4]   .text.foo
   [    7]   .data.foo

COMDAT group section [    2] `.group' [.text.foo.1] contains 2 sections:
   [Index]    Name
   [    5]   .text.foo.1
   [    8]   .data.bar
bash-3.2$ 

"ld -r" generates wrong group signature.
