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

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.

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>

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.
