From 268533381f80d18698fea9b15f942427f1d34cba Mon Sep 17 00:00:00 2001 From: "H.J. Lu" Date: Thu, 13 Jan 2022 05:43:05 -0800 Subject: [PATCH] Reapply libiberty: Pass --plugin to AR and RANLIB Reapply the patch to detect GCC LTO plugin used for libiberty build to support LTO build in libiberty. * Makefile.in (AR): Add @AR_PLUGIN_OPTION@ (RANLIB): Add @RANLIB_PLUGIN_OPTION@. (configure_deps): Depend on ../config/gcc-plugin.m4. * aclocal.m4: Include ../config/gcc-plugin.m4. * configure.ac: AC_SUBST AR_PLUGIN_OPTION and RANLIB_PLUGIN_OPTION. * configure: Regenerate. --- libiberty/Makefile.in | 5 +- libiberty/aclocal.m4 | 1 + libiberty/configure | 154 +++++++++++++++++++++++++++++++++++++---- libiberty/configure.ac | 12 ++++ 4 files changed, 157 insertions(+), 15 deletions(-) diff --git a/libiberty/Makefile.in b/libiberty/Makefile.in index 1b17c2e3a47..abef3c4601b 100644 --- a/libiberty/Makefile.in +++ b/libiberty/Makefile.in @@ -50,13 +50,13 @@ mkinstalldirs = $(SHELL) $(libiberty_topdir)/mkinstalldirs # Some compilers can't handle cc -c blah.c -o foo/blah.o.
