glibc: backport fix for vfork on mips
glibc-2.23 fails to build for mips with nptl/libpthread.so:(*IND*+0x0): multiple definition of `vfork@GLIBC_2.0'; This was fixed in glibc-2.24. Backport the fix for glibc-2.23. Fixes #1744 Signed-off-by: Chris Packham <judge.packham@gmail.com>

Subject: [PATCH] MIPS, SPARC: fix wrong vfork aliases in libpthread.so
|
||||
|
||||
With recent binutils versions the GNU libc fails to build on at least
|
||||
MISP and SPARC, with this kind of error:
|
||||
|
||||
/home/aurel32/glibc/glibc-build/nptl/libpthread.so:(*IND*+0x0): multiple definition of `vfork@GLIBC_2.0'
|
||||
/home/aurel32/glibc/glibc-build/nptl/libpthread.so::(.text+0xee50): first defined here
|
||||
|
||||
It appears that on these architectures pt-vfork.S includes vfork.S
|
||||
(through the alpha version of pt-vfork.S) and that the __vfork aliases
|
||||
are not conditionalized on IS_IN (libc) like on other architectures.
|
||||
Therefore the aliases are also wrongly included in libpthread.so.
|
||||
|
||||
Fix this by properly conditionalizing the aliases like on other
|
||||
architectures.
|
||||
|
||||
Changelog:
|
||||
* sysdeps/unix/sysv/linux/mips/vfork.S (__vfork): Conditionalize
|
||||
hidden_def, weak_alias and strong_alias on [IS_IN (libc)].
|
||||
* sysdeps/unix/sysv/linux/sparc/sparc32/vfork.S: Likewise.
|
||||
* sysdeps/unix/sysv/linux/sparc/sparc64/vfork.S: Likewise.

MIPS, SPARC: more fixes to the vfork aliases in libpthread.so
|
||||
|
||||
Commit 43c29487 tried to fix the vfork aliases in libpthread.so on MIPS
|
||||
and SPARC, but failed to do it correctly, introducing an ABI change.
|
||||
|
||||
This patch does the remaining changes needed to align the MIPS and SPARC
|
||||
vfork implementations with the other architectures. That way the the
|
||||
alpha version of pt-vfork.S works correctly for MIPS and SPARC. The
|
||||
changes for alpha were done in 82aab97c.
|
||||
|
||||
Changelog:
|
||||
* sysdeps/unix/sysv/linux/mips/vfork.S (__vfork): Rename into
|
||||
__libc_vfork.
|
||||
(__vfork) [IS_IN (libc)]: Remove alias.
|
||||
(__libc_vfork) [IS_IN (libc)]: Define as an alias.
|
||||
* sysdeps/unix/sysv/linux/sparc/sparc32/vfork.S: Likewise.
|
||||
* sysdeps/unix/sysv/linux/sparc/sparc64/vfork.S: Likewise.
