From a3fb6b6bc3f2f33e93f4c9575105f3b5f39cb201 Mon Sep 17 00:00:00 2001 From: Joseph Myers Date: Fri, 27 Apr 2018 19:11:24 +0000 Subject: Remove tilegx port. Since tile support has been removed from the Linux kernel for 4.17, this patch removes the (unmaintained) port to tilegx from glibc (the tilepro support having been previously removed). This reflects the general principle that a glibc port needs upstream support for the architecture in all the components it build-depends on (so binutils, GCC and the Linux kernel, for the normal case of a port supporting the Linux kernel but no other OS), in order to be maintainable. Apart from removal of sysdeps/tile and sysdeps/unix/sysv/linux/tile, there are updates to various comments referencing tile for which removal of those references seemed appropriate. The configuration is removed from README and from build-many-glibcs.py. contrib.texi keeps mention of removed contributions, but I updated Chris Metcalf's entry to reflect that he also contributed the non-removed support for the generic Linux kernel syscall interface. __ASSUME_FADVISE64_64_NO_ALIGN support is removed, as it was only used by tile. * sysdeps/tile: Remove. * sysdeps/unix/sysv/linux/tile: Likewise. * README (tilegx-*-linux-gnu): Remove from list of supported configurations. * manual/contrib.texi (Contributors): Mention Chris Metcalf's contribution of support for generic Linux kernel syscall interface. * scripts/build-many-glibcs.py (Context.add_all_configs): Remove tilegx configurations. (Config.install_linux_headers): Do not handle tile. * sysdeps/unix/sysv/linux/aarch64/ldsodefs.h: Do not mention Tile in comment. * sysdeps/unix/sysv/linux/nios2/Makefile: Likewise. * sysdeps/unix/sysv/linux/posix_fadvise.c: Likewise. [__ASSUME_FADVISE64_64_NO_ALIGN] (__ALIGNMENT_ARG): Remove conditional undefine and redefine. * sysdeps/unix/sysv/linux/posix_fadvise64.c: Do not mention Tile in comment. [__ASSUME_FADVISE64_64_NO_ALIGN] (__ALIGNMENT_ARG): Remove conditional undefine and redefine. --- sysdeps/tile/tls-macros.h | 65 ----------------------------------------------- 1 file changed, 65 deletions(-) delete mode 100644 sysdeps/tile/tls-macros.h (limited to 'sysdeps/tile/tls-macros.h') diff --git a/sysdeps/tile/tls-macros.h b/sysdeps/tile/tls-macros.h deleted file mode 100644 index 162d309254..0000000000 --- a/sysdeps/tile/tls-macros.h +++ /dev/null @@ -1,65 +0,0 @@ -/* Copyright (C) 2011-2018 Free Software Foundation, Inc. - This file is part of the GNU C Library. - Contributed by Chris Metcalf , 2011. - - 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.
