Accepting request 844381 from home:alois:branches:devel:libraries:c_c++ - Update to version 7.1.0 * Switched from Grisu3 to Dragonbox for the default floating-point formatting which gives the shortest decimal representation with round-trip guarantee and correct rounding. This makes {fmt} up to 20-30x faster than common implementations of std::ostringstream and sprintf on dtoa-benchmark and faster than double-conversion and Ryū. It is possible to get even better performance at the cost of larger binary size by compiling with the FMT_USE_FULL_CACHE_DRAGONBOX macro set to 1. * Added an experimental unsynchronized file output API which, together with format string compilation can give 5-9 times speed up compared to fprintf on common platforms. * Added a formatter for std::chrono::time_point<system_clock> * Added support for ranges with non-const begin/end to fmt::join * Added a memory_buffer::append overload that takes a range. * Improved handling of single code units in FMT_COMPILE. * Added dynamic width support to format string compilation. * Improved error reporting for unformattable types: now you'll get the type name directly in the error message instead of the note. * Added the make_args_checked function template that allows you to write formatting functions with compile-time format string checks and avoid binary code bloat. * Replaced snprintf fallback with a faster internal IEEE 754 float and double formatter for arbitrary precision. * Made format_to_n and formatted_size part of the core API. * Added fmt::format_to_n overload with format string compilation. * Added fmt::format_to overload that take text_style. * Made the # specifier emit trailing zeros in addition to the decimal point. * Changed the default floating point format to not include .0 for consistency with std::format and std::to_chars. It is possible to get the decimal point and trailing zero with the # specifier. * Fixed an issue with floating-point formatting that could result in addition of a non-significant trailing zero in rare cases e.g. 1.00e-34 instead of 1.0e-34. * Made fmt::to_string fallback on ostream insertion operator if the formatter specialization is not provided. * Added support for the append mode to the experimental file API and improved fcntl.h detection. * Fixed handling of types that have both an implicit conversion operator and an overloaded ostream insertion operator. * Fixed a slicing issue in an internal iterator type. * Fixed an issue in locale-specific integer formatting. * Fixed handling of exotic code unit types. * Improved FMT_ALWAYS_INLINE. * Improved documentation. * Added the FMT_REDUCE_INT_INSTANTIATIONS CMake option that reduces the binary code size at the cost of some integer formatting performance. This can be useful for extremely memory-constrained embedded systems. * Added the FMT_USE_INLINE_NAMESPACES macro to control usage of inline namespaces. * Improved build configuration. * Fixed various warnings and compilation issues. - Add fmt-7.1.0-LTO.patch OBS-URL: https://build.opensuse.org/request/show/844381 OBS-URL: https://build.opensuse.org/package/show/devel:libraries:c_c++/fmt?expand=0&rev=33
