Subject: [PATCH] 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.
