For example, 1089 if isdigit is mistakenly implemented via a static inline function, 1090 a program containing an extern inline function that calls isdigit 1091 may not work since the C standard prohibits extern inline functions 1092 from calling static functions (ISO C 99 section 6.7.4.(3). 1093 This bug is known to occur on: 1094 1095 OS X 10.8 and earlier; see: 1096 https://lists.gnu.org/r/bug-gnulib/2012-12/msg00023.html 1097 1098 DragonFly; see 1099 http://muscles.dragonflybsd.org/bulk/clang-master-potential/20141111_102002/logs/ah-tty-0.3.12.log 1100 1101 FreeBSD; see: 1102 https://lists.gnu.org/r/bug-gnulib/2014-07/msg00104.html 1103 1104 OS X 10.9 has a macro __header_inline indicating the bug is fixed for C and 1105 for clang but remains for g++; see <https://trac.macports.org/ticket/41033>. 1106 Assume DragonFly and FreeBSD will be similar. 1107 1108 GCC 4.3 and above with -std=c99 or -std=gnu99 implements ISO C99 1109 inline semantics, unless -fgnu89-inline is used. It defines a macro 1110 __GNUC_STDC_INLINE__ to indicate this situation or a macro 1111 __GNUC_GNU_INLINE__ to indicate the opposite situation. 1112 GCC 4.2 with -std=c99 or -std=gnu99 implements the GNU C inline 1113 semantics but warns, unless -fgnu89-inline is used: 1114 warning: C99 inline functions are not supported; using GNU89 1115 warning: to disable this warning use -fgnu89-inline or the gnu_inline function attribute 1116 It defines a macro __GNUC_GNU_INLINE__ to indicate this situation. 1117 */ 1118 #if (((defined __APPLE__ && defined __MACH__) \ 1119 || defined __DragonFly__ || defined __FreeBSD__) \ 1120 && (defined HAVE___HEADER_INLINE \ 1121 ?

Otherwise the compiler might optimize away stores to and 1560 reads from such locations that occur in the program, depending on its 1561 data flow analysis. For example, when the program contains a loop 1562 that is intended to inspect a variable set from within a signal handler 1563 while (!signal_occurred) 1564 ; 1565 the compiler is allowed to transform this into an endless loop if the 1566 variable 'signal_occurred' is not declared 'volatile'. 1567 Additionally, recall that: 1568 * A signal handler should not modify errno (except if it is a handler 1569 for a fatal signal and ends by raising the same signal again, thus 1570 provoking the termination of the process). If it invokes a function 1571 that may clobber errno, it needs to save and restore the value of 1572 errno. */ 1573 #define _GL_ASYNC_SAFE 1574 1575 1576 /* Attributes. */ 1577 #if (defined __has_attribute \ 1578 && (!defined __clang_minor__ \ 1579 || (defined __apple_build_version__ \ 1580 ? 6000000 <= __apple_build_version__ \ 1581 : 3 < __clang_major__ + (5 <= __clang_minor__)))) 1582 # define _GL_HAS_ATTRIBUTE(attr) __has_attribute (__##attr##__) 1583 #else 1584 # define _GL_HAS_ATTRIBUTE(attr) _GL_ATTR_##attr 1585 # define _GL_ATTR_alloc_size _GL_GNUC_PREREQ (4, 3) 1586 # define _GL_ATTR_always_inline _GL_GNUC_PREREQ (3, 2) 1587 # define _GL_ATTR_artificial _GL_GNUC_PREREQ (4, 3) 1588 # define _GL_ATTR_cold _GL_GNUC_PREREQ (4, 3) 1589 # define _GL_ATTR_const _GL_GNUC_PREREQ (2, 95) 1590 # define _GL_ATTR_deprecated _GL_GNUC_PREREQ (3, 1) 1591 # define _GL_ATTR_diagnose_if 0 1592 # define _GL_ATTR_error _GL_GNUC_PREREQ (4, 3) 1593 # define _GL_ATTR_externally_visible _GL_GNUC_PREREQ (4, 1) 1594 # define _GL_ATTR_fallthrough _GL_GNUC_PREREQ (7, 0) 1595 # define _GL_ATTR_format _GL_GNUC_PREREQ (2, 7) 1596 # define _GL_ATTR_leaf _GL_GNUC_PREREQ (4, 6) 1597 # define _GL_ATTR_malloc _GL_GNUC_PREREQ (3, 0) 1598 # ifdef _ICC 1599 # define _GL_ATTR_may_alias 0 1600 # else 1601 # define _GL_ATTR_may_alias _GL_GNUC_PREREQ (3, 3) 1602 # endif 1603 # define _GL_ATTR_noinline _GL_GNUC_PREREQ (3, 1) 1604 # define _GL_ATTR_nonnull _GL_GNUC_PREREQ (3, 3) 1605 # define _GL_ATTR_nonstring _GL_GNUC_PREREQ (8, 0) 1606 # define _GL_ATTR_nothrow _GL_GNUC_PREREQ (3, 3) 1607 # define _GL_ATTR_packed _GL_GNUC_PREREQ (2, 7) 1608 # define _GL_ATTR_pure _GL_GNUC_PREREQ (2, 96) 1609 # define _GL_ATTR_returns_nonnull _GL_GNUC_PREREQ (4, 9) 1610 # define _GL_ATTR_sentinel _GL_GNUC_PREREQ (4, 0) 1611 # define _GL_ATTR_unused _GL_GNUC_PREREQ (2, 7) 1612 # define _GL_ATTR_warn_unused_result _GL_GNUC_PREREQ (3, 4) 1613 #endif 1614 1615 #ifdef __has_c_attribute 1616 # if ((defined __STDC_VERSION__ ? __STDC_VERSION__ : 0) <= 201710 \ 1617 && _GL_GNUC_PREREQ (4, 6)) 1618 # pragma GCC diagnostic ignored "-Wpedantic" 1619 # endif 1620 # define _GL_HAS_C_ATTRIBUTE(attr) __has_c_attribute (__##attr##__) 1621 #else 1622 # define _GL_HAS_C_ATTRIBUTE(attr) 0 1623 #endif 1624 1625 1626 /* _GL_ATTRIBUTE_ALLOC_SIZE ((N)) declares that the Nth argument of the function 1627 is the size of the returned memory block. 1628 _GL_ATTRIBUTE_ALLOC_SIZE ((M, N)) declares that the Mth argument multiplied 1629 by the Nth argument of the function is the size of the returned memory block. 1630 */ 1631 /* Applies to: function, pointer to function, function types. */ 1632 #if _GL_HAS_ATTRIBUTE (alloc_size) 1633 # define _GL_ATTRIBUTE_ALLOC_SIZE(args) __attribute__ ((__alloc_size__ args)) 1634 #else 1635 # define _GL_ATTRIBUTE_ALLOC_SIZE(args) 1636 #endif 1637 1638 /* _GL_ATTRIBUTE_ALWAYS_INLINE tells that the compiler should always inline the 1639 function and report an error if it cannot do so. */ 1640 /* Applies to: function. */ 1641 #if _GL_HAS_ATTRIBUTE (always_inline) 1642 # define _GL_ATTRIBUTE_ALWAYS_INLINE __attribute__ ((__always_inline__)) 1643 #else 1644 # define _GL_ATTRIBUTE_ALWAYS_INLINE 1645 #endif 1646 1647 /* _GL_ATTRIBUTE_ARTIFICIAL declares that the function is not important to show 1648 in stack traces when debugging.
