Paul Eggert 43a090ce 2015-09-25T00:01:10 c-ctype: rewrite to use inline functions This simplifies maintenance, since it makes for just one implementation of each function, letting the compiler have the fun of optimization. In practice this works well nowadays with GCC. E.g., c_isascii might need only three instructions even though the source code lists every ASCII character individually in a large switch statement. Also, fix some z/OS porting bugs reported by Daniel Richard G. in: http://lists.gnu.org/archive/html/bug-gnulib/2015-09/msg00037.html * NEWS: Document the API change. * lib/c-ctype.c: Drastically simplify, since this now just expands inline functions. * lib/c-ctype.h: Use _GL_INLINE_HEADER_BEGIN, _GL_INLINE_HEADER_END. (C_CTYPE_INLINE): New macro. (C_CTYPE_CONSECUTIVE_DIGITS, C_CTYPE_CONSECUTIVE_LOWERCASE) (C_CTYPE_CONSECUTIVE_UPPERCASE): Remove. Verify that either ASCII or EBCDIC is being used. (_C_CTYPE_SIGNED_EBCDIC, _C_CTYPE_CNTRL, _C_CTYPE_A_THRU_F_N) (_C_CTYPE_DIGIT_N, _C_CTYPE_LOWER_N, _C_CTYPE_UPPER_N) (_C_CTYPE_CASES, _C_CTYPE_A_THRU_F, _C_CTYPE_DIGIT, _C_CTYPE_LOWER) (_C_CTYPE_UPPER, _C_CTYPE_PUNCT_PLAIN): New private macros. (_C_CTYPE_CNTRL): In EBCDIC, '\x07' is a control, not '\xff'. (c_isalnum, c_isalpha, c_isascii, c_isblank, c_iscntrl, c_isdigit) (c_isgraph, c_islower, c_isprint, c_ispunct, c_isspace, c_isupper) (c_isxdigit, c_tolower, c_toupper): Now inline functions. (c_tolower, c_toupper): When converting, return the unsigned char, as that is what z/OS does. * lib/c-strcaseeq.h (CASEEQ): Simplify in the light of the removal of some c-ctype.h macros. * modules/c-ctype (Depends-on): Add extern-inline; remove verify. * tests/test-c-ctype.c (test_all): Fix test for c_toupper and c_tolower promotion to be compatible with z/OS.
Paul Eggert 4d83e798 2015-09-22T18:59:28 c-ctype: support EBCDIC-style c_isascii * lib/c-ctype.c (C_TYPE_EBCDIC): Move to top level. (c_isascii, c_iscntrl): Assume EBCDIC code page 1047 for control characters, if EBCDIC.
Paul Eggert 5c592b1c 2015-09-22T14:47:06 c-ctype: assume EBCDIC 1047 for c_iscntrl * lib/c-ctype.c (c_iscntrl): When EBCDIC, assume code page 1047 at both compile-time and at run-time. Check it at compile-time. We can worry about other code pages later, if the topic ever comes up. Fix typo in C_CTYPE_EBCDIC.
Paul Eggert 7e2a8ea2 2015-09-22T12:17:06 c-ctype: port better to EBCDIC Problems reported by Daniel Richard G. in http://lists.gnu.org/archive/html/bug-gnulib/2015-09/msg00020.html * lib/c-ctype.c: Include <limits.h>, for CHAR_MIN and CHAR_MAX. Include "verify.h". (C_CTYPE_ASCII, C_CTYPE_CONSECUTIVE_DIGITS) (C_CTYPE_CONSECUTIVE_LOWERCASE, C_CTYPE_CONSECUTIVE_UPPERCASE): Define as enum constants with value false, if not defined, so that code can use 'if' instead of 'ifdef'. Using 'if' helps make the code more portable, as both branches of the 'if' are compiled on all platforms. (C_CTYPE_EBCDIC): New constant. (to_char): New static function. (c_isalnum, c_isalpha, c_isdigit, c_islower, c_isgraph, c_isprint) (c_ispunct, c_isupper, c_isxdigit, c_tolower, c_toupper): Rewrite to use 'if' instead of 'ifdef'. Use to_char if non-ASCII. Prefer <= to >=. Prefer true and false to 1 and 0, for booleans. (c_iscntrl): Use 'if', not 'ifdef'. Special case for EBCDIC. Verify that the character set is either ASCII or EBCDIC. * tests/test-c-ctype.c: Include <limits.h>, for CHAR_MIN (to_char): New function. (test_all): Port to EBCDIC. Add some more tests, e.g., for c_ispunct.
