             Bug #: 14770
           Summary: s390 builds fail on binutils < 2.21.52.0.1
           Product: glibc
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: build
        AssignedTo: unassigned@sourceware.org
        ReportedBy: siddhesh@redhat.com
                CC: carlos@systemhalted.org
    Classification: Unclassified


08f43f9b added optimized versions of memcmp, memset and memcpy, in which the
.machine mnemonic is used.  This mnemonic is only supported on binutils >=
2.21.52.0.1 and glibc looks for 2.20 as the minimum version, so configure
incorrectly succeeds and the build fails later.

We started talking about how we could check whether ld is able to deal with
IFUNC symbols or not:

http://sourceware.org/ml/libc-alpha/2012-07/msg00051.html

Do we want something as proposed there? I'm not quite sure how portable such a
check is.

The S/390 glibc build currently needs Binutils 2.23 in order to have proper
IFUNC support.

Binutils 2.23 doesn't implement .machinemode yet.

We last increased the required binutils version with:

Author: Joseph Myers <joseph@codesourcery.com>

    Require binutils 2.20 or later.

It would probably be reasonable to increase the version (globally, for all
targets) again for glibc 2.20, if you wish to propose a patch.

We will need Binutils 2.24 released in December 2013 for:

- .machinemode when building 32 bit glibc
- and for tbegin being used for pthread lock elision

Binutils 2.24 is probably too recent to require it globally?  So we better do
it only for s390 - right?

Yes, I think that's too recent to require globally yet (but it might be 
reasonable to require binutils >= 2.23 and GCC >= 4.6 globally).
