            Bug ID: 102389
           Summary: [12 Regression] --with-build-config=bootstrap-lto
                    bootstrap is broken due to r12-3491
           Product: gcc
           Version: 12.0
            Status: UNCONFIRMED
          Keywords: build, lto
          Severity: normal
          Priority: P3
         Component: bootstrap
          Assignee: unassigned at gcc dot gnu.org
          Reporter: pinskia at gcc dot gnu.org
  Target Milestone: ---

----- CUT ----

After r12-3491-g9e58de3ce00, nm is used but libtool's configure breaks (it
looks like it was always broken, just we did not use that feature of libtool
until now):

Mine.  I have to see if using gcc-nm and exporting NM will fix this issue; it
might ...

Oh according to https://sourceware.org/bugzilla/show_bug.cgi?id=25355, we need
to require binutils 2.35 or newer to do this now.

--- Comment #4 from CVS Commits <cvs-commit at gcc dot gnu.org> ---
The trunk branch has been updated by Andrew Pinski <pinskia@gcc.gnu.org>:

https://gcc.gnu.org/g:68aace4458364fee201889aaaedfce59beb972f2

commit r12-3666-g68aace4458364fee201889aaaedfce59beb972f2
Author: Andrew Pinski <apinski@marvell.com>
Date:   Sat Sep 18 01:08:17 2021 +0000

    Fix PR bootstrap/102389: --with-build-config=bootstrap-lto is broken

    So the problem here is that now the lto-plugin requires NM that works
    with LTO to work so we need to pass down NM just like we do for ranlib
    and ar.

    OK? Bootstrapped and tested with --with-build-config=bootstrap-lto on
aarch64-linux-gnu.
    Note you need to use binutils 2.35 or later too due to
ttps://sourceware.org/PR25355
    (I will submit another patch to improve the installation instructions too).

    config/ChangeLog:

            PR bootstrap/102389
            * bootstrap-lto-lean.mk: Handle NM like RANLIB AND AR.
            * bootstrap-lto.mk: Likewise.
