           Summary: m68k statement ignored syntax error when
                    @TLSLDO+4(%a0)
           Product: binutils
           Version: 2.20
            Status: NEW
          Severity: normal
          Priority: P2
         Component: gas
        AssignedTo: address@hidden
        ReportedBy: address@hidden


Hi,

we’re not sure if this is a binutils bug, for not accepting this, or a
gcc bug, for producing code like this. (Personally, I don’t even know
m68k well…) If it’s a gcc bug, please tell me so and I’ll submit it there.

Sample code and diagnostics:

address@hidden:~ # cat x.s
        .globl  __tls_get_addr
        .text
        add.l address@hidden,%a2
        move.l %a1,address@hidden(%a0)
        move.l %a2,address@hidden(%a0)
        .section        .tbss
        .align  2
        .type   last.5547, @object
        .size   last.5547, 8
last.5547:
        .zero   8
address@hidden:~ # as --version

ignored

This is on Debian/m68k, which I’m currently putting through a transition
to do TLS manually. I’ve not tried any other version because building
binutils takes half a day or so, and maybe someone can shed some insight
into this already, but if it’s necessary, I will.
