Jim Meyering 9e62d63e 2011-06-02T10:05:59 mark functions with const and pure attributes Mark functions per suggestions from gcc-4.6 when using these options: -Wsuggest-attribute=pure -Wsuggest-attribute=const. Use gnulib's _GL_ATTRIBUTE_PURE and _GL_ATTRIBUTE_CONST macros. Follow these guidelines: when possible, apply the attribute to an extern declaration, not to its definition. Apply it to the definition only when the definition is static. * lib/argmatch.h (argmatch, argmatch_to_argument): Mark. * lib/argv-iter.h (argv_iter_n_args): Likewise. * lib/base64.h (isbase64): Likewise. * lib/basename-lgpl.c (last_component, base_len): Likewise. * lib/c-ctype.h (c_isascii, c_isalnum, c_isalpha): Likewise. (c_isblank, c_iscntrl, c_isdigit, c_islower, c_isgraph): Likewise. (c_isprint, c_ispunct, c_isspace, c_isupper, c_isxdigit): Likewise. (c_tolower, c_toupper): Likewise. * lib/c-strcase.h (c_strcasecmp, c_strncasecmp): Likewise. * lib/chdir-long.c (find_non_slash): Likewise. * lib/dirname.h (base_len, dir_len, last_component): Likewise. * lib/exclude.h (fnmatch_pattern_has_wildcards): Likewise. * lib/file-type.h (file_type): Likewise. * lib/filenamecat-lgpl.c (longest_relative_suffix): Likewise. * lib/filevercmp.c (verrevcmp): Likewise. * lib/freadahead.h (freadahead): Likewise. * lib/fts.c (fts_maxarglen): Likewise. * lib/hash-pjw.h (hash_pjw): Likewise. * lib/hash-triple.h (triple_hash_no_name, triple_compare_ino_str): * lib/hash.c (is_prime, next_prime): Likewise. * lib/hash.c (hash_get_n_buckets, hash_get_n_buckets_used): Likewise. (hash_get_n_entries, hash_get_max_bucket_length): Likewise. (hash_table_ok, hash_get_first, hash_string): Likewise.

(quoting_options_from_style): Add a comment. * lib/propername.h (proper_name): Add a comment.
Bruno Haible 1b42459c 2011-10-09T12:14:12 isnanl[-nolibm]: Fix for platforms where 'long double' == 'double'. * lib/isnan.c (rpl_isnanl): Don't blindly assume 80-bit 'long double'. * m4/isnanl.m4 (gl_PREREQ_ISNANL): Require gl_LONG_DOUBLE_VS_DOUBLE. (gl_FUNC_ISNANL_WORKS): Likewise. Don't blindly assume 80-bit 'long double'. * modules/isnanl-nolibm (Files): Add m4/math_h.m4.
Bruno Haible eef112c6 2011-09-17T17:58:10 isnanl, isnand, isnanf: Work around MSVC bug. * lib/isnan.c (FUNC): Use alternate ways of computing NaN and Infinity.
