From mboxrd@z Thu Jan 1 00:00:00 1970 From: Stafford Horne Date: Sat, 11 Dec 2021 08:34:54 +0900 Subject: [OpenRISC] [PATCH v3 11/13] or1k: Build Infrastructure In-Reply-To: <20211210233456.4146479-1-shorne@gmail.com> References: <20211210233456.4146479-1-shorne@gmail.com> Message-ID: <20211210233456.4146479-12-shorne@gmail.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: openrisc@lists.librecores.org Here we define the minumum linux kernel version at 5.4.0, as that is the long term support version where 32-bit architectures start to support 64-bit time API's. The OpenRISC kernel had some bugs up until version 5.8 which caused issues with glibc fork/clone, they have been backported to 5.4 but not previous versions. --- sysdeps/or1k/Implies | 3 ++ sysdeps/or1k/Makefile | 7 +++++ sysdeps/or1k/nofpu/Implies | 1 + sysdeps/or1k/nptl/Makefile | 21 +++++++++++++ sysdeps/or1k/preconfigure | 34 +++++++++++++++++++++ sysdeps/unix/sysv/linux/or1k/Implies | 3 ++ sysdeps/unix/sysv/linux/or1k/Makefile | 12 ++++++++ sysdeps/unix/sysv/linux/or1k/configure | 4 +++ sysdeps/unix/sysv/linux/or1k/configure.ac | 4 +++ sysdeps/unix/sysv/linux/or1k/shlib-versions | 2 ++ 10 files changed, 91 insertions(+) create mode 100644 sysdeps/or1k/Implies create mode 100644 sysdeps/or1k/Makefile create mode 100644 sysdeps/or1k/nofpu/Implies create mode 100644 sysdeps/or1k/nptl/Makefile create mode 100644 sysdeps/or1k/preconfigure create mode 100644 sysdeps/unix/sysv/linux/or1k/Implies create mode 100644 sysdeps/unix/sysv/linux/or1k/Makefile create mode 100644 sysdeps/unix/sysv/linux/or1k/configure create mode 100644 sysdeps/unix/sysv/linux/or1k/configure.ac create mode 100644 sysdeps/unix/sysv/linux/or1k/shlib-versions diff --git a/sysdeps/or1k/Implies b/sysdeps/or1k/Implies new file mode 100644 index 0000000000..387a0ca052 --- /dev/null +++ b/sysdeps/or1k/Implies @@ -0,0 +1,3 @@ +wordsize-32 +ieee754/dbl-64 +ieee754/flt-32 diff --git a/sysdeps/or1k/Makefile b/sysdeps/or1k/Makefile new file mode 100644 index 0000000000..0241a0587e --- /dev/null +++ b/sysdeps/or1k/Makefile @@ -0,0 +1,7 @@ +ASFLAGS-.os += -fPIC + +ifeq ($(subdir),elf) +# Extra shared linker files to link only into dl-allobjs.so. +sysdep-rtld-routines += dl-start +endif + diff --git a/sysdeps/or1k/nofpu/Implies b/sysdeps/or1k/nofpu/Implies new file mode 100644 index 0000000000..abcbadb25f --- /dev/null +++ b/sysdeps/or1k/nofpu/Implies @@ -0,0 +1 @@ +ieee754/soft-fp diff --git a/sysdeps/or1k/nptl/Makefile b/sysdeps/or1k/nptl/Makefile new file mode 100644 index 0000000000..0e08821933 --- /dev/null +++ b/sysdeps/or1k/nptl/Makefile @@ -0,0 +1,21 @@ +# Copyright (C) 2021 Free Software Foundation, Inc. +# +# This file is part of the GNU C Library. +# +# The GNU C Library is free software; you can redistribute it and/or +# modify it under the terms of the GNU Lesser General Public +# License as published by the Free Software Foundation; either +# version 2.1 of the License, or (at your option) any later version. +# +# The GNU C Library 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.
