If defined, the io, string, and valarray 45// headers will include all the necessary bits. If not defined, the 46// implementation optimizes the headers for the most commonly-used 47// types. For the io library, this means that larger, out-of-line 48// member functions are only declared, and definitions are not parsed 49// by the compiler, but instead instantiated into the library binary. 50#define _GLIBCPP_FULLY_COMPLIANT_HEADERS 1 51 52// To enable older, ARM-style iostreams and other anachronisms use this. 53//#define _GLIBCPP_DEPRECATED 1 54 55// Use corrected code from the committee library group's issues list. 56#define _GLIBCPP_RESOLVE_LIB_DEFECTS 1 57 58// In those parts of the standard C++ library that use a mutex instead 59// of a spin-lock, we now unconditionally use GCC's gthr.h mutex 60// abstraction layer. All support to directly map to various 61// threading models has been removed. Note: gthr.h may well map to 62// gthr-single.h which is a correct way to express no threads support 63// in gcc. Support for the undocumented _NOTHREADS has been removed. 64 65// Default to the typically high-speed, pool-based allocator (as 66// libstdc++-v2) instead of the malloc-based allocator (libstdc++-v3 67// snapshots). See libstdc++-v3/docs/html/17_intro/howto.html for 68// details on why you don't want to override this setting. Ensure 69// that threads are properly configured on your platform before 70// assigning blame to the STL container-memory allocator. After doing 71// so, please report any possible issues to libstdc++@gcc.gnu.org . 72// Do not define __USE_MALLOC on the command line. Enforce it here: 73#ifdef __USE_MALLOC 74#error __USE_MALLOC should only be defined within \ 75libstdc++-v3/include/bits/c++config before full recompilation of the library. 76#endif 77// Define __USE_MALLOC after this point in the file in order to aid debugging 78// or globally change allocation policy. This breaks the ABI, thus 79// completely recompile the library. A patch to better support 80// changing the global allocator policy would be probably be accepted. 81 82// The remainder of the prewritten config is mostly automatic; all the 83// user hooks are listed above. 84 85// End of prewritten config; the discovered settings follow. 86
