Rainer Orth bb89747721 ld: Disable ifunc tests on Solaris
A couple of ld ifunc tests currently FAIL on 64-bit Solaris/x86:

FAIL: ld-ifunc/ifunc-10-x86-64
FAIL: ld-ifunc/ifunc-11-x86-64
FAIL: ld-ifunc/ifunc-12-x86-64

FAIL: ld-ifunc/pr17154-x86-64-now
FAIL: ld-ifunc/pr17154-x86-64

For one, the actual error is weird:

./ld-new: target elf64-x86-64 not found
failed with: <./ld-new: target elf64-x86-64 not found>, no expected output
FAIL: ld-ifunc/ifunc-10-x86-64

although ld -V does report the elf_x86_64 emulation as supported:

$ ./ld/ld-new -V
GNU ld (GNU Binutils) 2.34.50.20200328
  Supported emulations:
   elf_x86_64_sol2
   elf_x86_64
[...]

When using ld -m elf_x86_64_sol2 instead, one of the testcases links
successfully.

However, there's no point in pursuing this: Solaris does not support
ifunc, as can be seen in <sys/elf.h>:

/*
 * GNU/Linux specific symbol type not used by Solaris
 */
#define STT_GNU_IFUNC   10

and never will, given that it has symbol capabilities as solution to
effectively the same problem:

http://www.linker-aliens.org/blogs/rie/entry/symbol_capabilitie/

Therefore this patch disables ifunc testing on Solaris completely by
removing Solaris from binutils/testsuite/lib/binutils-common.exp
(supports_gnu_osabi).  The ifunc part is justified above.  SHF_GNU_MBIND is
in the OS-specific range and conflicts with

#define SHF_SUNW_REALLOC        0x01000000      /* internal: krtld realloc */

While the comment suggests this might be relocatable without too much
problems, the description of mbind (no formal spec AFAICS, just the
comment in the binutils patch submission) strongly suggests that this
isn't relevant to Solaris at all.

Indirectly, clearing supports_gnu_osabi on Solaris disables
supports_gnu_unique.  Again, Solaris <sys/elf.h> has

/*
 * GNU/Linux specific binding not used by Solaris
 */
#define STB_GNU_UNIQUE  10

so this seems the right thing to do.

Afterwards, one can remove the explicit mentions of *-*-solaris2* in
quite a number of (but not all) the ld-ifunc dump file notarget lists.

There's one fallout, though: two gas tests now XPASS because they are
xfail'ed for !supports_gnu_osabi:

XPASS: mbind sections 12
XPASS: mbind section contents 16
XPASS: mbind sections 16
XPASS: mbind section contents 16

To fix that, I've changed

#xfail: ![supports_gnu_osabi]

to notarget.

Tested on x86_64-pc-solaris2.11, i386-pc-solaris2.11,
x86_64-pc-linux-gnu, and i686-pc-linux-gnu.

		   README for GNU development tools

This directory contains various GNU compilers, assemblers, linkers, 
debuggers, etc., plus their support routines, definitions, and documentation.

If you are receiving this as part of a GDB release, see the file gdb/README.
If with a binutils release, see binutils/README;  if with a libg++ release,
see libg++/README, etc.  That'll give you info about this
package -- supported targets, how to use it, how to report bugs, etc.

It is now possible to automatically configure and build a variety of
tools with one command.  To build all of the tools contained herein,
run the ``configure'' script here, e.g.:

	./configure 
	make

To install them (by default in /usr/local/bin, /usr/local/lib, etc),
then do:
	make install

(If the configure script can't determine your type of computer, give it
the name as an argument, for instance ``./configure sun4''.  You can
use the script ``config.sub'' to test whether a name is recognized; if
it is, config.sub translates it to a triplet specifying CPU, vendor,
and OS.)

If you have more than one compiler on your system, it is often best to
explicitly set CC in the environment before running configure, and to
also set CC when running make.  For example (assuming sh/bash/ksh):

	CC=gcc ./configure
	make

A similar example using csh:

	setenv CC gcc
	./configure
	make

Much of the code and documentation enclosed is copyright by
the Free Software Foundation, Inc.  See the file COPYING or
COPYING.LIB in the various directories, for a description of the
GNU General Public License terms under which you can copy the files.

REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info
on where and how to report problems.
