From c08f85d74f2964c00613930342bfa27f971fc2be Mon Sep 17 00:00:00 2001 From: Paul Eggert Date: Fri, 1 May 2020 18:12:12 -0700 Subject: attribute: new module MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This simplifies use of GCC and C2X attributes like ‘deprecated’. * MODULES.html.sh: Add attribute. * doc/attribute.texi, lib/attribute.h, modules/attribute: New files. * doc/gnulib.texi (Particular Modules): Add Attributes. * lib/backupfile.c, lib/fnmatch.c, lib/freopen-safer.c: * lib/mbrtoc32.c, lib/mbrtowc.c, lib/nstrftime.c, lib/quotearg.c: * lib/savewd.c, lib/unistr/u8-uctomb-aux.c, lib/unistr/u8-uctomb.c: * lib/vasnprintf.c: Include attribute.h, and let it define FALLTHROUGH. * lib/bitset/base.h, lib/c-stack.c (__attribute__): Remove macro. * lib/bitset/base.h (ATTRIBUTE_UNUSED): Define in terms of _GL_ATTRIBUTE_MAYBE_UNUSED, for forwards compatibility to C2X. * lib/dfa.c (FALLTHROUGH): Define consistently with gl_COMMON_BODY. This is a copy since Gawk doesn’t use Gnulib. * lib/di-set.h (_GL_ATTRIBUTE_NONNULL): Remove definition that is incompatible with gl_COMMON_BODY’s. All uses changed. * lib/fts.c: Include attribte.h, for FALLTHROUGH. Keep the existing FALLTHROUGH definition since Glibc might use it, and it does no harm to Gnulib’s FALLTHROUGH. * lib/fts_.h, lib/inttostr.h: (__GNUC_PREREQ): Remove; no longer needed. (__attribute_warn_unused_result__): Remove. All uses replaced by _GL_ATTRIBUTE_NODISCARD. * lib/gl_list.h, lib/gl_map.h, lib/gl_omap.h, lib/gl_oset.h: * lib/gl_set.h: Prefer _GL_ATTRIBUTE_NODISCARD to an ifdeffed __attribute__ ((__warn_unused_result__)), for forward compatibility to C2X. * lib/hash.h (_GL_ATTRIBUTE_WUR): Remove. All uses replaced by _GL_ATTRIBUTE_NODISCARD. (_GL_ATTRIBUTE_DEPRECATED): Remove, since gl_COMMON_BODY defines it. * lib/ino-map.h (_GL_ATTRIBUTE_NONNULL): Remove. All uses replaced by gl_COMMON_BODY’s implementation, which has a slightly different signature. * lib/safe-alloc.h (_GL_ATTRIBUTE_RETURN_CHECK): Remove. All uses replaced by _GL_ATTRIBUTE_NODISCARD. * lib/unused-parameter.h (_GL_UNUSED_PARAMETER): Define in terms of _GL_ATTRIBUTE_MAYBE_UNUSED. No doubt all uses should be replaced, at some point. * m4/gnulib-common.m4 (_GL_GNUC_PREREQ): New macro. (_Noreturn): Use it.
