            Bug ID: 77315
           Summary: emit DW_OP_form_tls_address
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: debug
          Assignee: unassigned at gcc dot gnu.org
          Reporter: tromey at gcc dot gnu.org
  Target Milestone: ---

Currently gcc generally emits DW_OP_GNU_push_tls_address for the location
of a thread-local.  However, it seems to me that the standard
DW_OP_form_tls_address is equivalent but slightly better due to being
standard.  Note though that gdb generally doesn't implement the standard
form, so that would have to be done first.
