Sync with binutils for building binutils with LTO: >From 50ad1254d5030d0804cbf89c758359ae202e8d55 Mon Sep 17 00:00:00 2001 From: "H.J. Lu" <hjl.to...@gmail.com> Date: Sat, 9 Jan 2021 06:43:11 -0800 Subject: [PATCH] GCC: Pass --plugin to AR and RANLIB
Detect GCC LTO plugin. Pass --plugin to AR and RANLIB to support LTO build. * Makefile.tpl (AR): Add @AR_PLUGIN_OPTION@ (RANLIB): Add @RANLIB_PLUGIN_OPTION@. * configure.ac: Include config/gcc-plugin.m4. AC_SUBST AR_PLUGIN_OPTION and RANLIB_PLUGIN_OPTION. * libtool.m4 (_LT_CMD_OLD_ARCHIVE): Pass --plugin to AR and RANLIB if possible. * Makefile.in: Regenerated. * configure: Likewise. config/ * gcc-plugin.m4 (GCC_PLUGIN_OPTION): New. libiberty/ * Makefile.in (AR): Add @AR_PLUGIN_OPTION@ (RANLIB): Add @RANLIB_PLUGIN_OPTION@. (configure_deps): Depend on ../config/gcc-plugin.m4. * configure.ac: AC_SUBST AR_PLUGIN_OPTION and RANLIB_PLUGIN_OPTION. * aclocal.m4: Regenerated. * configure: Likewise. zlib/ * configure: Regenerated. --- Makefile.in | 5 ++-- Makefile.tpl | 5 ++-- config/gcc-plugin.m4 | 28 +++++++++++++++++++ configure | 39 ++++++++++++++++++++++++++ configure.ac | 15 ++++++++++ libiberty/Makefile.in | 5 ++-- libiberty/aclocal.m4 | 1 + libiberty/configure | 63 ++++++++++++++++++++++++++++-------------- libiberty/configure.ac | 12 ++++++++ libtool.m4 | 25 ++++++++++++++++- zlib/configure | 29 +++++++++++++++++-- 11 files changed, 197 insertions(+), 30 deletions(-) diff --git a/Makefile.in b/Makefile.in index ab883f69115..a72a288cda6 100644 --- a/Makefile.in +++ b/Makefile.in @@ -401,7 +401,7 @@ MAKEINFOFLAGS = --split-size=5000000 # --------------------------------------------- AS = @AS@ -AR = @AR@ +AR = @AR@ @AR_PLUGIN_OPTION@ AR_FLAGS = rc CC = @CC@ CXX = @CXX@ @@ -411,7 +411,7 @@ LIPO = @LIPO@ NM = @NM@ OBJDUMP = @OBJDUMP@ OTOOL = @OTOOL@ -RANLIB = @RANLIB@ +RANLIB = @RANLIB@ @RANLIB_PLUGIN_OPTION@ READELF = @READELF@ STRIP = @STRIP@ WINDRES = @WINDRES@ @@ -61403,6 +61403,7 @@ AUTOCONF = autoconf $(srcdir)/configure: @MAINT@ $(srcdir)/configure.ac $(srcdir)/config/acx.m4 \ $(srcdir)/config/override.m4 $(srcdir)/config/proginstall.m4 \ $(srcdir)/config/elf.m4 $(srcdir)/config/isl.m4 \ + $(srcdir)/config/gcc-plugin.m4 \ $(srcdir)/libtool.m4 $(srcdir)/ltoptions.m4 $(srcdir)/ltsugar.m4 \ $(srcdir)/ltversion.m4 $(srcdir)/lt~obsolete.m4 cd $(srcdir) && $(AUTOCONF) diff --git a/Makefile.tpl b/Makefile.tpl index 6e0337fb48f..ae139c8914e 100644 --- a/Makefile.tpl +++ b/Makefile.tpl @@ -404,7 +404,7 @@ MAKEINFOFLAGS = --split-size=5000000 # --------------------------------------------- AS = @AS@ -AR = @AR@ +AR = @AR@ @AR_PLUGIN_OPTION@ AR_FLAGS = rc CC = @CC@ CXX = @CXX@ @@ -414,7 +414,7 @@ LIPO = @LIPO@ NM = @NM@ OBJDUMP = @OBJDUMP@ OTOOL = @OTOOL@ -RANLIB = @RANLIB@ +RANLIB = @RANLIB@ @RANLIB_PLUGIN_OPTION@ READELF = @READELF@ STRIP = @STRIP@ WINDRES = @WINDRES@ @@ -2007,6 +2007,7 @@ AUTOCONF = autoconf $(srcdir)/configure: @MAINT@ $(srcdir)/configure.ac $(srcdir)/config/acx.m4 \ $(srcdir)/config/override.m4 $(srcdir)/config/proginstall.m4 \ $(srcdir)/config/elf.m4 $(srcdir)/config/isl.m4 \ + $(srcdir)/config/gcc-plugin.m4 \ $(srcdir)/libtool.m4 $(srcdir)/ltoptions.m4 $(srcdir)/ltsugar.m4 \ $(srcdir)/ltversion.m4 $(srcdir)/lt~obsolete.m4 cd $(srcdir) && $(AUTOCONF) diff --git a/config/gcc-plugin.m4 b/config/gcc-plugin.m4 index 8f278719118..c5b72e9a13d 100644 --- a/config/gcc-plugin.m4 +++ b/config/gcc-plugin.m4 @@ -124,3 +124,31 @@ AC_DEFUN([GCC_ENABLE_PLUGINS], fi fi ]) + +dnl +dnl +dnl GCC_PLUGIN_OPTION +dnl (SHELL-CODE_HANDLER) +dnl +AC_DEFUN([GCC_PLUGIN_OPTION],[dnl +AC_MSG_CHECKING([for -plugin option]) + +plugin_names="liblto_plugin.so liblto_plugin-0.dll cyglto_plugin-0.dll" +plugin_option= +for plugin in $plugin_names; do + plugin_so=`${CC} ${CFLAGS} --print-prog-name $plugin` + if test x$plugin_so = x$plugin; then + plugin_so=`${CC} ${CFLAGS} --print-file-name $plugin` + fi + if test x$plugin_so != x$plugin; then + plugin_option="--plugin $plugin_so" + break + fi +done +if test -n "$plugin_option"; then + $1="$plugin_option" + AC_MSG_RESULT($plugin_option) +else + AC_MSG_RESULT([no]) +fi +]) diff --git a/configure b/configure index 1224fc4039e..6d2fc6eb5b4 100755 --- a/configure +++ b/configure @@ -618,6 +618,8 @@ GFORTRAN_FOR_TARGET GCC_FOR_TARGET CXX_FOR_TARGET CC_FOR_TARGET +RANLIB_PLUGIN_OPTION +AR_PLUGIN_OPTION READELF OTOOL OBJDUMP @@ -12434,6 +12436,43 @@ fi +{ $as_echo "$as_me:${as_lineno-$LINENO}: checking for -plugin option" >&5 +$as_echo_n "checking for -plugin option...
