43 // This is a hack around not having either pre-compiled headers or
44 // export compilation. 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.

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.
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:
74 #error __USE_MALLOC should only be defined within \
75 libstdc++-v3/include/bits/c++config before full recompilation of the library.
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.
82 // The remainder of the prewritten config is mostly automatic; all the
83 // user hooks are listed above.
85 // End of prewritten config; the discovered settings follow.
