--- Comment #6 from John David Anglin <danglin at gcc dot gnu.org> ---
Looking further, I have concluded $global$ and %r19 are set correctly. The
relocations for

.Lpmain:
        .word P%main
.Lp__libc_start_main:
        .word P%__libc_start_main
.Lp__libc_csu_fini:
        .word P%__libc_csu_fini
.Lp__libc_csu_init:
        .word P%__libc_csu_init

are not correct.  The relocation for

.Lp__global:
        .word $global$

is okay.
