commit f7b425175c3fa2f063a6c5657d84b799929db459
Author: Joseph Myers <joseph@codesourcery.com>

    Support and use mixed compat/non-compat aliases in syscalls.list.
    
    This patch enables syscalls.list entries to specify both compat and
    non-compat symbol versions for the same syscall definition, making use
    of this for setrlimit / chown / lchown where the inability to specify
    such aliases showed up in the course of work on bug 14138.
    
    The change to make-syscalls.sh is minimal: adding a SHARED conditional
    on the compat_symbol calls.  It remains the case that if a compat
    symbol version is specified, the syscall is only built for the shared
    library at all if an explicit symbol version is given for a non-compat
    symbol (so it's necessary to specify "lchown@@GLIBC_2.0
    chown@GLIBC_2.0" rather than just "lchown chown@GLIBC_2.0").  It also
    remains the case, as already commented in make-syscalls.sh, that no
    SHLIB_COMPAT conditionals are generated, so there would be problems if
    the same syscalls.list file, with compat symbols, were used for both
    configurations that should have those symbols and configurations for
    which they should be conditioned out with SHLIB_COMPAT.
    
    Tested for x86.
    
    	* sysdeps/unix/make-syscalls.sh (emit_weak_aliases): Condition
    	compat_symbol calls on [SHARED].
    	* sysdeps/unix/sysv/linux/powerpc/lchown.S: Remove file.
    	* sysdeps/unix/sysv/linux/i386/syscalls.list (oldsetrlimit):
    	Remove.

    	(oldsetrlimit): Remove.
    	(setrlimit): Add setrlimit@GLIBC_2.0 alias.
