* attribute: new modulePaul Eggert2020-05-031-8/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. (_GL_HAS_ATTRIBUTE, _GL_ATTRIBUTE_ALLOC_SIZE) (_GL_ATTRIBUTE_ALWAYS_INLINE, _GL_ATTRIBUTE_ARTIFICIAL) (_GL_ATTRIBUTE_COLD) (_GL_ATTRIBUTE_DEPRECATED, _GL_ATTRIBUTE_ERROR) (_GL_ATTRIBUTE_WARNING, _GL_ATTRIBUTE_EXTERNALLY_VISIBLE) (_GL_ATTRIBUTE_FALLTHROUGH, _GL_ATTRIBUTE_FORMAT) (_GL_ATTRIBUTE_LEAF, _GL_ATTRIBUTE_MAY_ALIAS) (_GL_ATTRIBUTE_MAYBE_UNUSED) (_GL_ATTRIBUTE_NODISCARD, _GL_ATTRIBUTE_NOINLINE) (_GL_ATTRIBUTE_NONNULL, _GL_ATTRIBUTE_NONSTRING) (_GL_ATTRIBUTE_NOTHROW, _GL_ATTRIBUTE_PACKED, _GL_ATTRIBUTE_PURE) (_GL_ATTRIBUTE_SENTINEL): New macros. * modules/backup-rename, modules/backupfile, modules/c-vasnprintf: * modules/fnmatch, modules/freopen-safer, modules/fts: * modules/mbrtoc32, modules/mbrtowc, modules/nstrftime: * modules/quotearg, modules/savewd: * modules/unistdio/u16-u16-vasnprintf: * modules/unistdio/u16-vasnprintf: * modules/unistdio/u32-u32-vasnprintf: * modules/unistdio/u32-vasnprintf: * modules/unistdio/u8-u8-vasnprintf: * modules/unistdio/u8-vasnprintf: * modules/unistdio/ulc-vasnprintf: * modules/unistr/u8-uctomb, modules/vasnprintf: (Depends-on:): Add attribute module.

* fallthrough: update for GCC 7/8Jim Meyering2017-05-191-3/+11
| | | | | | | | | | | | | | | | * lib/quotearg.c (FALLTHROUGH): New macro. Use it whenever one switch case falls through into the next, replacing "/* Fall through */" comments. This exposed one instance of an unwarranted "fall through" comment: unwarranted because it preceded a "goto" label not a case statement. * lib/freopen-safer.c (freopen_safer): Likewise. * lib/fts.c (leaf_optimization_applies): Likewise. * lib/unistr/u8-uctomb-aux.c (u8_uctomb_aux): Likewise. * tests/test-getopt_long.h (getopt_long_loop): Likewise. * tests/test-tsearch.c (mangle_tree): Likewise. Also include tests/macros.h for the definition. * tests/test-argp.c (group1_parser): Likewise. * tests/test-getopt.h (getopt_loop): Likewise.
