Hi,

r216964 disables bootstrap for libcc1 which exposed 2 things:

1. libcc1 isn't compiled with LTO even when GCC is configured with
"--with-build-config=bootstrap-lto".  It may be intentional since
libcc1 is disabled for bootstrap.
2. -fPIC isn't used to created libcc1.so, which is OK if libcc1 is
compiled with LTO which remembers PIC option.

libiberty is bootstrapped with LTO.  When libcc1 isn't compiled with
LTO, we are creating libcc1.so without -fPIC, which leads to linker
failure when linking with slim-lto libiberty.  This patch from

https://gcc.gnu.org/ml/gcc-patches/2012-09/msg00991.html

adds -fPIC to -shared so that -fPIC is always used to create shared
object.  Tested on Linux/x86-64.  OK for trunk?

Thanks.

Why is this any special to LTO?  If it is then it looks like a LTO
(driver) issue to me?  Why are we linking the pic libibterty into
a non-pic libcc1?

I admit I haven't tried LTO bootstrap, but from normal bootstrap logs,
libcc1 is built normally using libtool using -fPIC only, and linked into
libcc1.so.0.0.0 and libcc1plugin.so.0.0.0, and of course against the
pic/libiberty.a, because we need PIC code in the shared libraries.
So, I don't understand the change at all.

This is the command line to build libcc1.la:

There are no -fPIC nor any other options, like -O2.  Since *.lo aren't
compiled with LTO
and libiberty/pic/libiberty.a is compiled with LTO, linker uses
libtool command line to
compile libiberty/pic/libiberty.a  LTO IR into regular object.   Since
libtool command line
doesn't have -fPIC, it fails to create shared object.  Since it
doesn't have -O2, it isn't
optimized and misses other options.

Both ld and gold pull the compiler options from the first .o file with
LTO IR.  We can
argue if linker should pull compiler option from the first LTO IR in
.o and .a.  But it
doesn't happen today and may not be desirable at all.

Sure, but there was -fPIC used to compile all the *.o files that are being
linked into libcc1.so, so LTO should know that.

And it does.  If not please file a bug with a smaller testcase than libcc1
and libiberty.

Ah, supposedly we should add $(POSTSTAGE1_HOST_EXPORTS) after $(HOST_EXPORTS)
to the libcc1 rules iff the libcc1 module is built by the newly built
bootstrapped compiler (but not when the compiler is not bootstrapped and
thus it is built by the host compiler), because if we first bootstrap the
compiler and build libcc1 by stage3, it is really post-stage1 building.

Paolo, any thoughts how to arrange that?

There is nothing wrong with linker.  It is a slm-lto bug in libtool.  I uploaded
a testcase at

It doesn't help. The problem is the missing -fPIC when libtool calls
g+++ to create the shared object.  My patch fixes it.

But wouldn't it be better to update to a more recent libtool version
instead of adding hack upon hack? 
This would also allow bootstrap-lto without the need of the gcc-ar
(, etc.) wrappers.

And you are one of the very few persons who could handle such an update.

Hack is safer than the newer libtool :-(.  A new libtool needs to be
verified on all hosts for all targets.

Well, perhaps now is the right time to do it, because there would be
enough time to fix any fallout.

I mean that since Ralf Wildenhues dropped from the scene, you (H.J.) are
one of the few people who could handle a libtool update across the
different trees (gcc, binutils, etc.).

I can handle binutils.  But it takes a LONG time for GCC build changes
to be reviewed.  I try to avoid it as much as I can :-).

My patch is a backport of libtool LTO support:

commit b81fd4ef009c24a86a7e64727ea09efb410ea149
Author: Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
Date:   Sun Aug 29 17:31:29 2010 +0200

    Support GCC LTO on GNU/Linux.

    * libltdl/config/ltmain.m4sh (func_mode_link): Allow through
    flags matching -O*, -flto*, -fwhopr, -fuse-linker-plugin.
    * libltdl/m4/libtool.m4 (_LT_CMD_GLOBAL_SYMBOLS): Drop symbols
    starting with __gnu_lto.
    (_LT_LINKER_SHLIBS) [linux] <archive_cmds, archive_expsyms_cmds>:
    Add $pic_flag for GCC.
    (_LT_LANG_CXX_CONFIG) [linux] <archive_cmds, archive_expsyms_cmds>:
    Likewise.
    (_LT_SYS_HIDDEN_LIBDEPS): Ignore files matching *.lto.o.
    * NEWS: Update.

    Signed-off-by: Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

OK to install?

Stage 1 will be closed tomorrow.  I'd like to restore LTO bootstrap.

Bugfixing is still possible after that date.  I suppose you don't call
LTO bootstrap a new feature ;)
