358 | * The main reason for this is that the combination of gcc -Wunused-result | |
359 | * (part of -Wall) and the __attribute__((warn_unused_result)) cannot | |
360 | * be silenced with casting to void. This causes trouble when the system | |
361 | * header files use the attribute. | |
362 | * | |
363 | * Use PERL_UNUSED_RESULT sparingly, though, since usually the warning | |
364 | * is there for a good reason: you might lose success/failure information, | |
365 | * or leak resources, or changes in resources. | |
ffea512f JH |
366 | * |
367 | * But sometimes you just want to ignore the return value, e.g. on | |
b469f1e0 JH |
368 | * codepaths soon ending up in abort, or in "best effort" attempts, |
369 | * or in situations where there is no good way to handle failures. | |
ffea512f | 370 | * |
b469f1e0 JH |
371 | * Sometimes PERL_UNUSED_RESULT might not be the most natural way: |
372 | * another possibility is that you can capture the return value | |
373 | * and use PERL_UNUSED_VAR on that. | |
ffea512f | 374 | * |
b469f1e0 JH |
375 | * The __typeof__() is used instead of typeof() since typeof() is not |
376 | * available under strict C89, and because of compilers masquerading | |
377 | * as gcc (clang and icc), we want exactly the gcc extension | |
378 | * __typeof__ and nothing else. | |

6084 | ||
6085 | This macro should be used as a statement. It declares a private variable | |
6086 | (whose name begins with an underscore) that is needed by the other macros in | |
6087 | this section. Failing to include this correctly should lead to a syntax error. | |
6088 | For compatibility with C89 C compilers it should be placed in a block before | |
6089 | any executable statements. | |
6090 | ||
6091 | =for apidoc Am|void|STORE_LC_NUMERIC_FORCE_TO_UNDERLYING | |
6092 | ||
6093 | This is used by XS code that that is C<LC_NUMERIC> locale-aware to force the | |
6094 | locale for category C<LC_NUMERIC> to be what perl thinks is the current | |
6095 | underlying locale. (The perl interpreter could be wrong about what the | |
6096 | underlying locale actually is if some C or XS code has called the C library | |
6097 | function L<setlocale(3)> behind its back; calling L</sync_locale> before calling | |
6098 | this macro will update perl's records.) | |
6099 | ||
6100 | A call to L</DECLARATION_FOR_LC_NUMERIC_MANIPULATION> must have been made to | |
6101 | declare at compile time a private variable used by this macro. This macro | |
6102 | should be called as a single statement, not an expression, but with an empty | |
6103 | argument list, like this: | |
6104 | ||
6105 | { | |
6106 | DECLARATION_FOR_LC_NUMERIC_MANIPULATION; | |
6107 | ... | |
6108 | STORE_LC_NUMERIC_FORCE_TO_UNDERLYING(); | |
6109 | ... | |
6110 | RESTORE_LC_NUMERIC(); | |
6111 | ... | |
6112 | } | |
6113 | ||
6114 | The private variable is used to save the current locale state, so | |
6115 | that the requisite matching call to L</RESTORE_LC_NUMERIC> can restore it. | |
6116 | ||
6117 | =for apidoc Am|void|STORE_LC_NUMERIC_SET_TO_NEEDED | |
6118 | ||
6119 | This is used to help wrap XS or C code that that is C<LC_NUMERIC> locale-aware. | |
6120 | This locale category is generally kept set to the C locale by Perl for | |
6121 | backwards compatibility, and because most XS code that reads floating point | |
6122 | values can cope only with the decimal radix character being a dot. | |
6123 | ||
6124 | This macro makes sure the current C<LC_NUMERIC> state is set properly, to be | |
6125 | aware of locale if the call to the XS or C code from the Perl program is | |
6126 | from within the scope of a S<C<use locale>>; or to ignore locale if the call is | |
6127 | instead from outside such scope. | |
6128 | ||
6129 | This macro is the start of wrapping the C or XS code; the wrap ending is done | |
6130 | by calling the L</RESTORE_LC_NUMERIC> macro after the operation. Otherwise | |
6131 | the state can be changed that will adversely affect other XS code. | |
6132 | ||
6133 | A call to L</DECLARATION_FOR_LC_NUMERIC_MANIPULATION> must have been made to | |
6134 | declare at compile time a private variable used by this macro. This macro | |
6135 | should be called as a single statement, not an expression, but with an empty | |
6136 | argument list, like this: | |
6137 | ||
6138 | { | |
6139 | DECLARATION_FOR_LC_NUMERIC_MANIPULATION; | |
6140 | ... | |
6141 | STORE_LC_NUMERIC_SET_TO_NEEDED(); | |
6142 | ... | |
6143 | RESTORE_LC_NUMERIC(); | |
6144 | ... | |
6145 | } | |
6146 | ||
6147 | =for apidoc Am|void|RESTORE_LC_NUMERIC | |
6148 | ||
6149 | This is used in conjunction with one of the macros | |
6150 | L</STORE_LC_NUMERIC_SET_TO_NEEDED> | |
6151 | and | |
6152 | L</STORE_LC_NUMERIC_FORCE_TO_UNDERLYING> | |
6153 | ||
6154 | to properly restore the C<LC_NUMERIC> state. | |
6155 | ||
6156 | A call to L</DECLARATION_FOR_LC_NUMERIC_MANIPULATION> must have been made to | |
6157 | declare at compile time a private variable used by this macro and the two | |
6158 | C<STORE> ones. This macro should be called as a single statement, not an | |
6159 | expression, but with an empty argument list, like this: | |
6160 | ||
6161 | { | |
6162 | DECLARATION_FOR_LC_NUMERIC_MANIPULATION; | |
6163 | ... | |
6164 | RESTORE_LC_NUMERIC(); | |
6165 | ... | |

6850 | * | |
6851 | * q = Quietness bit, the interpretation is platform-specific. | |
453b60f1 | 6852 | * Most platforms have the most significant bit being one |
5c255b3b JH |
6853 | * meaning quiet, but some (older mips, hppa) have the msb |
6854 | * being one meaning signaling. Note that the above means | |
6855 | * that on most platforms there cannot be signaling nan with | |
453b60f1 JH |
6856 | * zero payload because that is identical with infinity; |
6857 | * while conversely on older mips/hppa there cannot be a quiet nan | |
6858 | * because that is identical with infinity. | |
6859 | * | |
6860 | * Moreover, whether there is any behavioral difference | |
6861 | * between quiet and signaling NaNs, depends on the platform. | |
5c255b3b JH |
6862 | * |
6863 | * x86 80-bit extended precision is different, the mantissa bits: | |
6864 | * | |
6865 | * 63 62 61 30387+ pre-387 visual c | |
6866 | * -------- ---- -------- -------- | |
6867 | * 0 0 0 invalid infinity | |
6868 | * 0 0 1 invalid snan | |
6869 | * 0 1 0 invalid snan | |
6870 | * 0 1 1 invalid snan | |
6871 | * 1 0 0 infinity snan 1.#INF | |
6872 | * 1 0 1 snan 1.#SNAN | |
6873 | * 1 1 0 qnan -1.#IND (x86 chooses this to negative) | |
6874 | * 1 1 1 qnan 1.#QNAN | |
6875 | * | |
6876 | * This means that in this format there are 61 bits available | |
6877 | * for the nan payload. | |
6878 | * | |
3bbe6a60 JH |
6879 | * Note that the 32-bit x86 ABI cannot do signaling nans: the x87 |
6880 | * simply cannot preserve the bit. You can either use the 80-bit | |
6881 | * extended precision (long double, -Duselongdouble), or use x86-64. | |
6882 | * | |
453b60f1 JH |
6883 | * In all platforms, the payload bytes (and bits, some of them are |
6884 | * often in a partial byte) themselves can be either all zero (x86), | |
6885 | * all one (sparc or mips), or a mixture: in IEEE 754 128-bit double | |
6886 | * or in a double-double, the first half of the payload can follow the | |
6887 | * native double, while in the second half the payload can be all | |
6888 | * zeros. (Therefore the mask for payload bits is not necessarily | |
6889 | * identical to bit complement of the NaN.) Another way of putting | |
6890 | * this: the payload for the default NaN might not be zero. | |
6891 | * | |
6892 | * For the x86 80-bit long doubles, the trailing bytes (the 80 bits | |
6893 | * being 'packaged' in either 12 or 16 bytes) can be whatever random | |
6894 | * garbage. | |
6895 | * | |
6896 | * Furthermore, the semantics of the sign bit on NaNs are platform-specific. | |
6897 | * On normal floats, the sign bit being on means negative. But this may, | |
6898 | * or may not, be reverted on NaNs: in other words, the default NaN might | |
6899 | * have the sign bit on, and therefore look like negative if you look | |
6900 | * at it at the bit level. | |
6901 | * | |
6902 | * NaN payloads are not propagated even on copies, or in arithmetics. | |
6903 | * They *might* be, according to some rules, on your particular | |
6904 | * cpu/os/compiler/libraries, but no guarantees. | |
6905 | * | |
6906 | * To summarize, on most platforms, and for 64-bit doubles | |
6907 | * (using big-endian ordering here): | |
6908 | * | |
6909 | * [7FF8000000000000..7FFFFFFFFFFFFFFF] quiet | |
6910 | * [FFF8000000000000..FFFFFFFFFFFFFFFF] quiet | |
6911 | * [7FF0000000000001..7FF7FFFFFFFFFFFF] signaling | |
6912 | * [FFF0000000000001..FFF7FFFFFFFFFFFF] signaling | |
6913 | * | |
6914 | * The C99 nan() is supposed to generate *quiet* NaNs. | |
6915 | * | |
6916 | * Note the asymmetry: | |
6917 | * The 7FF0000000000000 is positive infinity, | |
6918 | * the FFF0000000000000 is negative infinity. | |
