From b8ff24c72174effd5c5527866313982e28507275 Mon Sep 17 00:00:00 2001 From: Vlad Zakharov Date: Mon, 26 Sep 2016 16:36:08 +0100 Subject: [PATCH 2/2] When building target binaries, ensure that the warning flags selected for the command line match the target compiler. bfd * warning.m4 (AC_EGREP_CPP_FOR_BUILD): Introduce macro to verify CC_FOR_BUILD compiler. (AM_BINUTILS_WARNINGS): Introduce ac_cpp_for_build variable and add CC_FOR_BUILD compiler checks. * Makefile.in: Regenerate. * configure: Likewise. * doc/Makefile.in: Likewise. binutils * Makefile.am: Replace AM_CLFAGS with AM_CFLAGS_FOR_BUILD when building with CC_FOR_BUILD compiler. * Makefile.in: Regenerate. * configure: Likewise. * doc/Makefile.in: Likewise. gas * Makefile.in: Regenerate. * configure: Likewise. * doc/Makefile.in: Likewise. gold * Makefile.in: Regenerate. * configure: Likewise. * testsuite/Makefile.in: Likewise. gprof * Makefile.in: Regenerate. * configure: Likewise. ld * Makefile.in: Regenerate. * configure: Likewise. opcodes * Makefile.in: Regenerate. * configure: Likewise. --- bfd/Makefile.in | 1 + bfd/configure | 56 +++++++++++++++++++++++++++++++++++++++++----- bfd/doc/Makefile.in | 1 + bfd/warning.m4 | 47 ++++++++++++++++++++++++++++++++++---- binutils/Makefile.am | 10 +++++---- binutils/Makefile.in | 10 +++++---- binutils/configure | 56 +++++++++++++++++++++++++++++++++++++++++----- binutils/doc/Makefile.in | 1 + gas/Makefile.in | 1 + gas/configure | 56 +++++++++++++++++++++++++++++++++++++++++----- gas/doc/Makefile.in | 1 + gold/Makefile.in | 5 +++-- gold/configure | 52 ++++++++++++++++++++++++++++++++++++++---- gold/testsuite/Makefile.in | 1 + gprof/Makefile.in | 1 + gprof/configure | 56 +++++++++++++++++++++++++++++++++++++++++----- ld/Makefile.in | 3 ++- ld/configure | 56 +++++++++++++++++++++++++++++++++++++++++----- opcodes/Makefile.in | 1 + opcodes/configure | 56 +++++++++++++++++++++++++++++++++++++++++----- 20 files changed, 416 insertions(+), 55 deletions(-) --- a/bfd/Makefile.in +++ b/bfd/Makefile.in @@ -288,6 +288,7 @@ TDEFINES = @TDEFINES@ USE_NLS = @USE_NLS@ VERSION = @VERSION@ WARN_CFLAGS = @WARN_CFLAGS@ +WARN_CFLAGS_FOR_BUILD = @WARN_CFLAGS_FOR_BUILD@ WARN_WRITE_STRINGS = @WARN_WRITE_STRINGS@ XGETTEXT = @XGETTEXT@ abs_builddir = @abs_builddir@ --- a/bfd/configure +++ b/bfd/configure @@ -659,6 +659,7 @@ MAINTAINER_MODE_FALSE MAINTAINER_MODE_TRUE WARN_WRITE_STRINGS NO_WERROR +WARN_CFLAGS_FOR_BUILD WARN_CFLAGS REPORT_BUGS_TEXI REPORT_BUGS_TO @@ -11427,7 +11428,7 @@ else lt_dlunknown=0; lt_dlno_uscore=1; lt_dlneed_uscore=2 lt_status=$lt_dlunknown cat > conftest.$ac_ext <<_LT_EOF -#line 11430 "configure" +#line 11431 "configure" #include "confdefs.h" #if HAVE_DLFCN_H @@ -11533,7 +11534,7 @@ else lt_dlunknown=0; lt_dlno_uscore=1; lt_dlneed_uscore=2 lt_status=$lt_dlunknown cat > conftest.$ac_ext <<_LT_EOF -#line 11536 "configure" +#line 11537 "configure" #include "confdefs.h" #if HAVE_DLFCN_H @@ -12240,8 +12241,12 @@ fi # Set the 'development' global. . $srcdir/../bfd/development.sh +# Set acp_cpp_for_build variable +ac_cpp_for_build="$CC_FOR_BUILD -E $CPPFLAGS_FOR_BUILD" + # Default set of GCC warnings to enable.
