Now with help of Crosstool-NG it is finally +possible to create uClibc-based multilibbed toolchains and so we add +relevant CPUs for multilib in case of configuration for "arc*-*-linux*". + +This will be essentially useful for glibc-based multilibbbed toolchains +in the future. + +gcc/ +2018-05-16 Alexey Brodkin <abrodkin@synopsys.com> + + * config.gcc: Add arc/t-multilib-linux to tmake_file for + arc*-*-linux*. + * config/arc/t-multilib-linux: Specify MULTILIB_OPTIONS and + MULTILIB_DIRNAMES + +git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@260434 138bc75d-0d04-0410-961f-82ee72b054a4 +--- + gcc/config.gcc | 2 +- + gcc/config/arc/t-multilib-linux | 25 +++++++++++++++++++++++++ + 2 files changed, 26 insertions(+), 1 deletion(-) + create mode 100644 gcc/config/arc/t-multilib-linux + +--- a/gcc/config.gcc ++++ b/gcc/config.gcc +@@ -1063,7 +1063,7 @@ + ;; + arc*-*-linux*) + tm_file="arc/arc-arch.h dbxelf.h elfos.h gnu-user.h linux.h linux-android.h glibc-stdint.h arc/linux.h ${tm_file}" +- tmake_file="${tmake_file} arc/t-arc" ++ tmake_file="${tmake_file} arc/t-multilib-linux arc/t-arc" + extra_gcc_objs="driver-arc.o" + if test "x$with_cpu" != x; then + tm_defines="${tm_defines} TARGET_CPU_BUILD=PROCESSOR_$with_cpu" +--- /dev/null ++++ b/gcc/config/arc/t-multilib-linux +@@ -0,0 +1,25 @@ ++# Copyright (C) 2018 Free Software Foundation, Inc. ++# ++# This file is part of GCC. ++# ++# GCC is free software; you can redistribute it and/or modify it under ++# the terms of the GNU General Public License as published by the Free ++# Software Foundation; either version 3, or (at your option) any later ++# version. ++# ++# GCC is distributed in the hope that it will be useful, but WITHOUT ANY ++# WARRANTY; without even the implied warranty of MERCHANTABILITY or ++# FITNESS FOR A PARTICULAR PURPOSE.
