d41bb613	2017-05-25T00:08:09	intprops: port to recent icc Port to icc (ICC) 17.0.4 20170411, which defines __GNUC__ to be 5 but does not support __builtin_add_overflow etc. * lib/intprops.h (_GL_HAS_BUILTIN_OVERFLOW) [__ICC]: Define to 0.
d9c44b2b	2017-05-08T10:37:48	intprops: don’t depend on ‘verify’ Problem reported by Ævar Arnfjörð Bjarmason in: http://lists.gnu.org/archive/html/bug-gnulib/2017-05/msg00054.html * lib/intprops.h: Do not include verify.h, and move compile-time checks from here ... * tests/test-intprops.c (main): ... to here, if they’re not here already. Check widths of other standard integer types. * modules/intprops (Depends-on): Remove ‘verify’.
5ea3e3a1	2017-04-15T14:27:11	intprops: improve comments * lib/intprops.h: Improve and shorten commentary. For the record, if we ever run into a pedantic compiler that behaves differently from GCC when converting an out-of-range value to a signed integer, we can work around the problem with something like the following code, where UCT is the signed counterpart of T (UCT is sometimes narrower than UT) and all callers are changed accordingly: ((t) ((ut) (a) op (ut) (b))) (TYPE_MINIMUM (t) <= (uct) ((ut) (a) op (ut) (b)) \ ? ((t) (uct) (((ut) (a) op (ut) (b)) - TYPE_MINIMUM (t)) \ + TYPE_MINIMUM (t)) \ : (t) (uct) ((ut) (a) op (ut) (b)))

749eb770	2017-04-14T18:55:42	intprops: try to avoid tickling similar bugs * lib/intprops.h (_GL_INT_OP_CALC): Document that UT no longer needs to be the same width as T; it can be wider. Change callers so that UT is at least as wide as unsigned int, as I suspect that this is less likely to run into compiler bugs.
a49b6ecc	2017-04-14T17:38:58	intprops: port to Oracle Studio 12.3 x86 Problem reported by Gavin Smith in: http://lists.gnu.org/archive/html/bug-gnulib/2017-04/msg00049.html * lib/intprops.h (_GL_INT_OP_WRAPV_VIA_UNSIGNED): Convert unsigned to signed via the usual rather than the standard way, to avoid a compiler bug in Oracle Studio 12.3 x86.
04441fd8	2017-01-06T13:36:57	glob, intprops, xalloc: work around Clang bug Work around LLVM bug 16404, which is still not fixed. https://llvm.org/bugs/show_bug.cgi?id=16404 Problem reported by Nelson H. F. Beebe. * lib/glob.c, lib/intprops.h, lib/xalloc-oversized.h (__has_builtin): Remove. * lib/glob.c (size_add_wrapv): * lib/intprops.h (_GL_HAS_BUILTIN_OVERFLOW, _GL_HAS_BUILTIN_OVERFLOW_P): * lib/xalloc-oversized.h (xalloc_oversized): Do not use overflow builtins if Clang.

5833fd5d	2016-11-03T21:34:58	intprops: port to older XL C Problem reported by Alexander Samoilov in: http://lists.gnu.org/archive/html/bug-gnulib/2016-10/msg00166.html http://savannah.nongnu.org/bugs/?49448 * lib/intprops.h (_GL_HAVE___TYPEOF__) [__IBM__TYPEOF__]: Define to 1 only for XL C 12.1 or later, since this bug occurs in XL C for AIX 6.0 but not in 12.1.
6625c98b	2016-09-13T21:49:10	intprops: new macro TYPE_WIDTH * lib/intprops.h (TYPE_WIDTH): New macro. (TYPE_MAXIMUM, _GL_SIGNED_INT_MAXIMUM, INT_STRLEN_BOUND): * lib/ftoastr.h (_GL_FLOAT_DIG_BITS_BOUND): * lib/parse-datetime.y (parse_datetime2): Use it.
39fca950	2016-08-30T12:29:21	intprops: tune INT_NEGATE_OVERFLOW for GCC 5 and 6 * lib/intprops.h (INT_NEGATE_OVERFLOW): Tune for platforms like GCC 5 and 6 that have __builtin_sub_overflow but not __builtin_sub_overflow_p. With the recent changes, these platforms are a tiny bit faster with the INT_NEGATE_RANGE_OVERFLOW implementation than with INT_SUBTRACT_OVERFLOW implementation, since the former needs just one runtime comparison whereas the latter needs two.
abae112b	2016-08-29T12:03:51	intprops.h: port recent changes to GCC 6.2.0 * lib/intprops.h (__has_builtin): Move earlier. (_GL_HAS_BUILTIN_OVERFLOW): Rename from _GL_HAS_BUILTIN_OVERFLOW_WITH_NULL and don't worry about whether the last argument can be null. All uses changed. (_GL_HAS_BUILTIN_OVERFLOW_P): Also test __has_builtin. (_GL_ADD_OVERFLOW, _GL_SUBTRACT_OVERFLOW, _GL_MULTIPLY_OVERFLOW): Don't try to use 3rd arg null, as this doesn't work on GCC 6.2.0 and it's not clear which GCC versions it works for. (_GL_INT_OP_WRAPV): Use _GL_HAS_BUILTIN_OVERFLOW instead of its definiens.
d22721e2	2016-08-29T10:08:32	intprops.h: use __typeof__ with GCC 7 * lib/intprops.h (_GL_ADD_OVERFLOW, _GL_SUBTRACT_OVERFLOW) (_GL_MULTIPLY_OVERFLOW): Use __typeof__ as in the GCC manual. This avoids computing the expression's value (which might overflow!).
175b4e22	2016-08-29T09:45:18	intprops.h, xalloc-oversized.h: work with gcc 7 In gcc 6, __builtin_add_overflow, __builtin_sub_overflow and __builtin_mul_overflow each accept a NULL pointer as the third argument. However in gcc 7, that is no longer accepted. Instead, one must use the "_p"-suffixed names, with which, the third parameter is no longer a pointer. * lib/intprops.h (_GL_HAS_BUILTIN_OVERFLOW_WITH_NULL): Correct the definition: not true for gcc 7 and subsequent. (_GL_HAS_BUILTIN_OVERFLOW_P): Define. (_GL_ADD_OVERFLOW, _GL_SUBTRACT_OVERFLOW, _GL_MULTIPLY_OVERFLOW): Provide new definitions for gcc 7 and subsequent. * lib/xalloc-oversized.h (xalloc_oversized): Provide a definition that works with gcc-7.
b9c364f0	2016-08-29T09:27:50	intprops.h: fix missing-backslash problems * lib/intprops.h (_GL_ADD_OVERFLOW): Add backslash. (_GL_SUBTRACT_OVERFLOW,_GL_MULTIPLY_OVERFLOW): Likewise.
f1012505	2016-08-24T22:24:48	intprops: fix paren typo on old platforms Problem reported by John E. Malmberg in: https://bugs.gnu.org/24300#13 * lib/intprops.h (_GL_INT_OP_WRAPV_LONGISH) [__GNUC__ < 5 && !__has_builtin (__builtin_add_overflow) && (__STDC_VERSION__ < 201112 \|\| _GL__GENERIC_BOGUS) && !defined LLONG_MAX]: Remove stray paren.
a073adb9	2016-08-24T20:48:32	intprops: port to OpenVMS Problem reported by John E. Malmberg in: https://bugs.gnu.org/24300 * doc/posix-headers/limits.texi: Document the problem. * lib/intprops.h (LLONG_MAX, LLONG_MIN) [__INT64_MAX]: Define if not already defined.
406465c5	2016-06-24T13:35:12	intprops: port better to GCC 7 GCC 7 __builtin_add_overflow supports a new usage form, where the last argument is a null pointer, and which merely returns 1 if an overflow would occur. This is a constant expression if all arguments are constants, and should generate faster code when code needs to be generated. * lib/intprops.h (_GL_HAS_BUILTIN_OVERFLOW_WITH_NULL): New macro. (_GL_ADD_OVERFLOW, _GL_SUBTRACT_OVERFLOW, _GL_MULTIPLY_OVERFLOW): Use builtin operations if available. (INT_NEGATE_OVERFLOW): Prefer INT_SUBTRACT_OVERFLOW if builtin operations are available, as it's almost surely faster.
b9e3fb39	2016-04-13T10:49:08	intprops: check two's complement assumption Suggested by Eric Blake in: http://lists.gnu.org/archive/html/bug-gnulib/2016-04/msg00016.html * lib/intprops.h: Include <verify.h>. Verify that signed char, short, int, long, and (if available) long long are two's complement. * modules/intprops (Depends-on): Add 'verify'.
a4910b94	2016-04-13T00:06:36	intprops, mktime, strtol: assume two's complement These macros were not portable to every conforming C11 ones' complement platform. It's not worth the hassle of porting to some platforms that use ones' complement or signed magnitude, as such platforms are almost purely theoretical nowadays and porting even to some of them makes the code harder to review for little practical benefit. Problem reported by Florian Weimer in: https://sourceware.org/ml/libc-alpha/2016-04/msg00295.html * lib/intprops.h (TYPE_TWOS_COMPLEMENT, TYPE_ONES_COMPLEMENT) (TYPE_SIGNED_MAGNITUDE, _GL_INT_TWOS_COMPLEMENT): * lib/mktime.c (TYPE_TWOS_COMPLEMENT): * lib/strtol.c (TYPE_TWOS_COMPLEMENT, TYPE_ONES_COMPLEMENT) (TYPE_SIGNED_MAGNITUDE): Remove. All uses rewritten to assume two's complement, which is all we can reasonably test nowadays anyway. * top/maint.mk (_intprops_names): Remove the removed macros.
841c4fa8	2016-03-08T16:35:58	intprops: make .h file license match module * lib/intprops.h: Change the license wording to match glibc format. This is what is in modules/intprops anyway. See: https://sourceware.org/bugzilla/show_bug.cgi?id=19738#c8

a2149646	2015-12-17T23:06:29	intprops: comment fix * lib/intprops.h: Fix comment. Reported by Pádraig Brady in: http://lists.gnu.org/archive/html/bug-gnulib/2015-12/msg00013.html
f197c2c9	2015-11-10T12:31:38	intprops: new public macro EXPR_SIGNED Emacs can use this macro, so make it public. * doc/intprops.texi (Arithmetic Type Properties): Rename from 'Integer Type Determination', since some of these macros apply to non-integer types. Clarify what kinds of constant expressions these macros return. Say when the arguments can be non-integers. Mention newly published macro EXPR_SIGNED. * lib/intprops.h (EXPR_SIGNED): Rename from _GL_INT_SIGNED, to make it public. All uses changed.
a66a3b96	2015-11-10T09:35:16	intprops: fix typo in clang port * lib/intprops.h (_GL_INT_OP_WRAPV): Fix misspelling of '__builtin_add_overflow' that is not caught by compiler.
8780c178	2015-11-04T08:27:57	intprops: revise _WRAPV macros, revert _OVERFLOW The incompatible changes to the _OVERFLOW macros were too much of a hassle in practice, so revert them. Instead, change the new _WRAPV macros to make them closer in behavior to GCC 5's new builtin_add_overflow etc. functions. No other software was using these newly-added macros yet, so this should be OK. * NEWS: Revert previous change, since the incompatible change has been reverted, and nobody used the incompatible version. * doc/intprops.texi (Wraparound Arithmetic, Integer Type Overflow): Document revised behavior. (Integer Range Overflow): Adjust example to match above revisions. * lib/intprops.h (INT_ADD_OVERFLOW, INT_SUBTRACT_OVERFLOW) (INT_MULTIPLY_OVERFLOW): Revert previous change, so that these can be used in integer constant expressions again. (INT_CONST_ADD_OVERFLOW, INT_CONST_SUBTRACT_OVERFLOW) (INT_CONST_MULTIPLY_OVERFLOW): Remove, as these are no longer needed. (INT_CONST_ADD_WRAPV, INT_CONST_SUBTRACT_WRAPV) (INT_NEGATE_WRAPV, INT_CONST_MULTIPLY_WRAPV, INT_DIVIDE_WRAPV) (INT_REMAINDER_WRAPV, INT_LEFT_SHIFT_WRAPV): Remove, as they did not seem that useful. (INT_ADD_WRAPV, INT_SUBTRACT_WRAPV, INT_MULTIPLY_WRAPV) (_GL_INT_OP_WRAPV, _GL_INT_OP_WRAPV_LONGISH) (_GL_INT_OP_WRAPV_VIA_UNSIGNED): Support new semantics. (__has_builtin): New macro, if not alreay defined. (_GL__GENERIC_BOGUS, _GL_INT_OP_CALC, _GL_INT_OP_CALC1): New macros. * tests/test-intprops.c (INT_CONST_DIVIDE_OVERFLOW) (INT_CONST_REMAINDER_OVERFLOW, INT_CONST_LEFT_SHIFT_OVERFLOW) (INT_CONST_DIVIDE_WRAPV, INT_CONST_REMAINDER_WRAPV) (INT_CONST_LEFT_SHIFT_WRAPV): Remove. (CHECK_SBINOP, CHECK_SSUM, CHECK_SUM1, CHECK_SSUM1) (CHECK_SDIFFERENCE, CHECK_SPRODUCT, CHECK_PRODUCT1, CHECK_SPRODUCT1): New macros. (CHECK_BINOP, CHECK_UNOP, main, CHECK_SUM): Test new behavior.
24fb386f	2015-11-03T08:32:27	intprops: add parentheses for when OP has precedence lower than "-" * lib/intprops.h (_GL_INT_OP_WRAPV_VIA_UNSIGNED): In "a OP b - c", "a OP b" must be parenthesized for when OP is like "<<", which has lower precedence than the following "-". Reported by Pádraig Brady.
86b1f082	2015-10-30T13:45:26	intprops: add WRAPV and const flavors for GCC 5 If available, use GCC 5's builtin functions for efficient integer overflow checking. Also, add macros like INT_ADD_WRAPV that efficently and safely compute the low-order bits of the correct answer. A downside of these efficient functions is that they cannot be used in constant expressions, so add macros like INT_CONST_ADD_OVERFLOW and INT_CONST_ADD_WRAPV that can be used even in constant expressions. * NEWS: Document the incompatible changes to INT_ADD_OVERFLOW etc. * doc/intprops.texi (Integer Properties, Integer Type Overflow): Document the changes. (Wraparound Arithmetic): New section. (Integer Range Overflow): Put this subsection last, since it's least useful. * lib/intprops.h (INT_CONST_ADD_OVERFLOW) (INT_CONST_SUBTRACT_OVERFLOW, INT_CONST_MULTIPLY_OVERFLOW): New macros, with the meaning that INT_ADD_OVERFLOW etc. used to have. (INT_CONST_ADD_WRAPV, INT_CONST_SUBTRACT_WRAPV) (INT_NEGATE_WRAPV, INT_CONST_MULTIPLY_WRAPV, INT_DIVIDE_WRAPV) (INT_REMAINDER_WRAPV, _GL_INT_OP_WRAPV, _GL_EXPR_CAST) (_GL_INT_OP_WRAPV_LONGISH, INT_ADD_WRAPV, INT_SUBTRACT_WRAPV) (INT_MULTIPLY_WRAPV, _GL_OP_OVERFLOW, _GL_OP_WRAPV, _GL_OP_WRAPV_GENSYM): New macros. (INT_ADD_OVERFLOW, INT_SUBTRACT_OVERFLOW, INT_MULTIPLY_OVERFLOW): Generate calls to GCC builtins if available, for speed. * tests/test-intprops.c (INT_CONST_DIVIDE_OVERFLOW) (INT_CONST_REMAINDER_OVERFLOW, INT_CONST_LEFT_SHIFT_OVERFLOW) (INT_CONST_DIVIDE_WRAPV, INT_CONST_REMAINDER_WRAPV) (INT_CONST_LEFT_SHIFT_WRAPV): New macros. (main, CHECK_BINOP, CHECK_UNOP, CHECK_SUM, CHECK_PRODUCT) (CHECK_QUOTIENT, CHECK_REMAINDER): Test WRAPV and CONST flavors (when available) too.
b9bfe784	2015-01-01T01:38:23	version-etc: new year * doc/gnulib.texi: * lib/version-etc.c (COPYRIGHT_YEAR): Update copyright date. * all files: Run 'make update-copyright'.

0488b6e8	2013-04-27T08:11:56	alignof, intprops, malloca: port better to IBM's C compiler * lib/alignof.h (alignof_type) [__IBM_ALIGNOF__]: Use __alignof__. * lib/intprops.h (_GL_HAVE___TYPEOF__) [__IBM_TYPEOF__]: Now 1. * lib/malloca.h (sa_alignof): [__IBM_ALIGNOF__]: Use __alignof__.

dabf3a8d	2011-05-28T12:34:08	intprops.h: adjust comment to match code change * lib/intprops.h (_GL_INT_CONVERT): Adjust comment: now that E is used only once, it may have side effects. Also fix an unrelated typo.
8aad2a7b	2011-05-24T16:45:14	intprops: shorten, to pacify gcc -Woverlength-strings * lib/intprops.h (_GL_INT_CONVERT, _GL_INT_NEGATE_CONVERT): (_GL_BINARY_OP_OVERFLOW): Say "0 * (x)" rather than "(x) - (x)", so that, for example, verify (INT_MULTIPLY_OVERFLOW (...)) is less likely to run afoul of C compiler limits for string constant lengths. See <http://lists.gnu.org/archive/html/bug-gnulib/2011-05/msg00528.html>.
48552f31	2011-05-20T11:30:16	intprops: remove assumption about A\|B representation * lib/intprops.h (_GL_BINARY_OP_OVERFLOW): Do not assume that A\|B is a valid integer if both A and B are. Although this is true for all known practical hosts, the C standard doesn't guarantee it, and the code need not assume it. Also, this change may work around HP-UX 11.23 and IRIX 6.5 cc bugs reported by Bruno Haible in <http://lists.gnu.org/archive/html/bug-gnulib/2011-05/msg00426.html>.
92c71a1c	2011-05-19T19:16:04	intprops: work around IRIX 6.5 cc bug with 0u - 0u + -1 See http://lists.gnu.org/archive/html/bug-gnulib/2011-05/msg00406.html * lib/intprops.h (_GL_INT_NEGATE_CONVERT): New macro. (_GL_INT_SIGNED, _GL_INT_MAXIMUM, _GL_DIVIDE_OVERFLOW): (_GL_REMAINDER_OVERFLOW): Use it.

f40658a3	2011-05-08T11:53:53	intprops: switch to usual gnulib indenting and naming * lib/intprops.h (_GL_INTPROPS_H): Rename from GL_INTPROPS_H. (_GL_SIGNED_TYPE_OR_EXPR): Rename from signed_type_or_expr__. * tests/test-inttostr.c (IS_TIGHT): Adjust to above renaming.
ee9e39c0	2011-01-29T23:59:31	TYPE_MAXIMUM: avoid theoretically undefined behavior * lib/intprops.h (TYPE_MINIMUM, TYPE_MAXIMUM): Do not shift a negative number, which the C Standard says has undefined behavior. In practice this is not a problem, but might as well do it by the book. Reported by Rich Felker and Eric Blake; see <http://lists.gnu.org/archive/html/bug-gnulib/2011-01/msg00493.html>. * lib/strtol.c (TYPE_MINIMUM, TYPE_MAXIMUM): Likewise. * m4/mktime.m4 (AC_FUNC_MKTIME): Likewise. * m4/nanosleep.m4 (gl_FUNC_NANOSLEEP): Likewise. * m4/parse-datetime.m4 (gl_PARSE_DATETIME): Likewise. * m4/stdint.m4 (gl_STDINT_H): Likewise. * lib/mktime.c (TYPE_MAXIMUM): Redo slightly to match the others.

This exposes an internal of intprops.h that was formerly not exposed. Also, it uses a slightly tighter bound than before; though this makes no practical difference, we might as well be as tight as we easily can.

intprops: improve comments * lib/intprops.h: Improve and shorten commentary. For the record, if we ever run into a pedantic compiler that behaves differently from GCC when converting an out-of-range value to a signed integer, we can work around the problem with something like the following code, where UCT is the signed counterpart of T (UCT is sometimes narrower than UT) and all callers are changed accordingly: ((t) ((ut) (a) op (ut) (b))) (TYPE_MINIMUM (t) <= (uct) ((ut) (a) op (ut) (b)) \ ? ((t) (uct) (((ut) (a) op (ut) (b)) - TYPE_MINIMUM (t)) \ + TYPE_MINIMUM (t)) \ : (t) (uct) ((ut) (a) op (ut) (b)))

intprops, mktime, strtol: assume two's complement These macros were not portable to every conforming C11 ones' complement platform. It's not worth the hassle of porting to some platforms that use ones' complement or signed magnitude, as such platforms are almost purely theoretical nowadays and porting even to some of them makes the code harder to review for little practical benefit.

intprops: add WRAPV and const flavors for GCC 5 If available, use GCC 5's builtin functions for efficient integer overflow checking. Also, add macros like INT_ADD_WRAPV that efficently and safely compute the low-order bits of the correct answer. A downside of these efficient functions is that they cannot be used in constant expressions, so add macros like INT_CONST_ADD_OVERFLOW and INT_CONST_ADD_WRAPV that can be used even in constant expressions. * NEWS: Document the incompatible changes to INT_ADD_OVERFLOW etc. * doc/intprops.texi (Integer Properties, Integer Type Overflow): Document the changes.
