Bug ID: 17719
Summary: [x86_64] memrchr 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
On x86_64, memrchr (not a standard function) is defined as a strong symbol,
instead of a weak alias of __memrchr as on other architectures. This results
in linknamespace test failures from the use of __memrchr from dirname. (Not a
conformance issue because of the mem* reservation, but contrary to glibc
conventions.)

commit 380292ba8b97c82a8ede3ed35f6a3c42b7b47466
Author: Joseph Myers <joseph@codesourcery.com>

Fix x86_64 memrchr namespace (bug 17719).
On x86_64, memrchr (not a standard function) is defined as a strong
symbol, instead of a weak alias of __memrchr as on other
architectures. This results in linknamespace test failures from the
use of __memrchr from dirname. (Not a conformance issue because of
the mem* reservation, but contrary to glibc conventions.) This patch
makes x86_64 follow other architectures by defining memrchr as a weak
alias.
Tested for x86_64 (testsuite, and that disassembly of installed shared
libraries is unchanged by the patch).
[BZ #17719]
* sysdeps/x86_64/memrchr.S (memrchr): Rename to __memrchr and
define as weak alias of __memrchr.
(__memrchr): Do not define as strong alias of memrchr.
* conform/Makefile (test-xfail-XPG4/libgen.h/linknamespace):
Remove variable.
(test-xfail-UNIX98/libgen.h/linknamespace): Likewise.
(test-xfail-XOPEN2K/libgen.h/linknamespace): Likewise.
(test-xfail-XOPEN2K8/libgen.h/linknamespace): Likewise.
