            Bug ID: 17572
           Summary: [x86_64] rawmemchr namespace
           Product: glibc
           Version: 2.21
            Status: NEW
          Severity: normal
          Priority: P2
         Component: libc
          Assignee: unassigned at sourceware dot org
          Reporter: jsm28 at gcc dot gnu.org
                CC: drepper.fsp at gmail dot com
              Host: x86_64-*

rawmemchr is not an ISO C function, while __rawmemchr gets called from ISO C
functions, so rawmemchr should be a weak alias, but on x86_64 it's strong
(other architectures appear to get this right).

commit 293d9a41805b1eeb440a2c59a717b332cd9c2384

    Fix x86_64 rawmemchr namespace (bug 17572).

    rawmemchr is not an ISO C function, but __rawmemchr is called from ISO
    C functions, so rawmemchr should be a weak alias.  On most
    architecture it is, but x86_64 defines the function as rawmemchr with
    __rawmemchr as a strong alias.  This patch makes x86_64 follow the
    same arrangements as other architectures.

    Tested for x86_64 (testsuite, and that disassembly of installed shared
    libraries is unchanged by the patch).

        [BZ #17572]
        * sysdeps/x86_64/rawmemchr.S (rawmemchr): Rename to __rawmemchr
        and define as weak alias of __rawmemchr.
        (__rawmemchr): Do not define as strong alias of rawmemchr.
