2021-09-19Fix PR bootstrap/102389: --with-build-config=bootstrap-lto is brokenAndrew Pinski1-2/+4
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.

Change the bootstrap-lto config file to use slim (non fat) LTO.. Speeds up the LTO bootstrap by ~18% on a 4 core system. This requires using gcc-ar/ranlib in post stage 1 builds, so these are passed to all sub builds. config/: 2014-09-01 Andi Kleen <ak@linux.intel.com> * bootstrap-lto.mk: Implement slim bootstrap. /: 2014-09-01 Andi Kleen <ak@linux.intel.com> * Makefile.tpl (POSTSTAGE1_HOST_EXPORTS): Add LTO_EXPORTS.
