[PATCH] Alpha build fixes


Hi!

Ok, a bunch of things in libc broke Alpha in the last 5 days:
a) size of sys_errlist problems
   - I have modified errlist-compat.awk script so that it picks up
     #errlist-compat comments from the first Versions file in the search
     path
b) the recent Alpha pipe.S move broke alpha-linux build, since
   linux/syscalls.list provides pipe
c) after I fixed Alpha visibility hidden in gcc 3.2 backport, I got errors
   when linking ld.so about relocation overflows - turns out _rtld_local
   was declared in section .sdata, so gcc can access
   it using GPREL16 relocs, but _rtld_global was not in .sdata and thus
   the overflows
d) symbol versioning for aio_cancel for backward compatibility with the
   bogus ECANCELED value on the problematic arches (alpha, sparc, hppa)
   plus related <bits/errno.h> fixes.

2002-08-28  Jakub Jelinek  <jakub@redhat.com>

	* sysdeps/generic/ldsodefs.h (__rtld_global_attribute__): Define.
	(_rtld_global): Use it.

	* sysdeps/gnu/Dist: Remove errlist-compat.c.
	* sysdeps/gnu/Makefile (errlist-compat.c): Build this file in the
	object directory.  Pass all Versions files to the awk script.
	* sysdeps/gnu/errlist-compat.c: Removed.
	* sysdeps/gnu/errlist.awk: Use #errlist-compat comments from the
	first Versions file in the search path which has them.
	Allow multiple errlist symbol versions to have the same count of
	errors.
	* sysdeps/gnu/errlist-compat.awk: Include <errlist-compat.c> instead
	of "errlist-compat.c".
	* sysdeps/gnu/errlist.c: Regenerated.
	* sysdeps/unix/sysv/linux/mips/Versions (libc): Add #errlist-compat
	comments at GLIBC_2.0, GLIBC_2.1 and GLIBC_2.3.
	* sysdeps/unix/sysv/linux/alpha/Versions: Likewise.
	(librt): Add aio_cancel and aio_cancel64 as GLIBC_2.3.
	* sysdeps/unix/sysv/linux/hppa/Versions: Likewise.
	* sysdeps/unix/sysv/linux/sparc/Versions: Likewise.
	* sysdeps/unix/sysv/linux/alpha/bits/errno.h: New file.
	* sysdeps/unix/sysv/linux/hppa/bits/errno.h (ECANCELED): Define to
	ECANCELLED if not defined by kernel headers.
	* sysdeps/unix/sysv/linux/bits/errno.h: Don't redefine ECANCELED if
	already defined by kernel headers.
	* sysdeps/unix/sysv/linux/sparc/bits/errno.h: New file.
	* sysdeps/pthread/aio_cancel.c: Don't include aio.h and its
	aio_cancel64 renaming hack nor provide weak_alias if aio_cancel
	is a macro.
	* Versions.def (GLIBC_2.3): Add.

	* sysdeps/unix/sysv/linux/alpha/pipe.S: New file.

linuxthreads/
	* sysdeps/unix/sysv/linux/hppa/aio_cancel.c: New file.
	* sysdeps/unix/sysv/linux/sparc/aio_cancel.c: New file.
	* sysdeps/unix/sysv/linux/alpha/aio_cancel.c: New file.
