From 8a1895a3fa6f634e9f459b6b62321a61c7941bdc Mon Sep 17 00:00:00 2001 From: Jessica Clarke Date: Thu, 12 Aug 2021 23:50:48 +0100 Subject: tools/build/cross-build: Fix building libllvmminimal on Linux There is a __used member in glibc's posix_spawn_file_actions_t in spawn.h, so we must temporarily undefine __used when including it, otherwise Support/Unix/Program.inc fails to build. This is based on similar handling for __unused in other headers. Fixes: 31ba4ce8898f ("Allow bootstrapping llvm-tblgen on macOS and Linux") MFC after: 1 week --- .../include/linux/__used_workaround_end.h | 43 ++++++++++++++++++++ .../include/linux/__used_workaround_start.h | 43 ++++++++++++++++++++ tools/build/cross-build/include/linux/spawn.h | 47 ++++++++++++++++++++++ 3 files changed, 133 insertions(+) create mode 100644 tools/build/cross-build/include/linux/__used_workaround_end.h create mode 100644 tools/build/cross-build/include/linux/__used_workaround_start.h create mode 100644 tools/build/cross-build/include/linux/spawn.h (limited to 'tools/build/cross-build/include') diff --git a/tools/build/cross-build/include/linux/__used_workaround_end.h b/tools/build/cross-build/include/linux/__used_workaround_end.h new file mode 100644 index 000000000000..99cc6c16ac26 --- /dev/null +++ b/tools/build/cross-build/include/linux/__used_workaround_end.h @@ -0,0 +1,43 @@ +/*- + * SPDX-License-Identifier: BSD-2-Clause + * + * Copyright 2018-2020 Alex Richardson + * Copyright 2021 Jessica Clarke + * + * This software was developed by SRI International and the University of + * Cambridge Computer Laboratory (Department of Computer Science and + * Technology) under DARPA contract HR0011-18-C-0016 ("ECATS"), as part of the + * DARPA SSITH research programme. + * + * This software was developed by SRI International and the University of + * Cambridge Computer Laboratory under DARPA/AFRL contract (FA8750-10-C-0237) + * ("CTSRD"), as part of the DARPA CRASH research programme. + * + * Redistribution and use in source and binary forms, with or without + * modification, are permitted provided that the following conditions + * are met: + * 1.
