The Standard C++ Library v3, or libstdc++-2.9x, is an ongoing
|

project to implement the ISO 14882 Standard C++ library as described
|

in chapters 17 through 27 and annex D, as a drop-in replacement
|

for the current (ARM-conformant) library.

This is the tenth snapshot of the libstdc++ rewrite. It is still

This is the eleventh snapshot of the libstdc++ rewrite. It is still

incomplet and incorrekt. It's a lot less incomplete and incorrect than

some of the earlier snapshots though, and quite usable.

New:
|
||||
---
|
||||
- namespace std:: is now on by default.
|
||||
- choice of "C" include strategies, including the shadow header work,
|
||||
or generic global to std mapping of required "C" types.
|
||||
- cpu/atomicity.h tweaks, additions of ia64 and arm support.
|
||||
- abstraction of atomicity.h header to support notion of os/atomicity.h files.
|
||||
- addition of backward header bits
|
||||
- use of system_header pragma
|
||||
- Conditional use of -Werror
|
||||
- preliminary support for new g++ diagnostics capabilities, including
|
||||
-fdiagnostics-show-location=once
|
||||
- pedantic and shadow argument warning fixes
|
||||
- Ugly, yet correct mechanism for dealing with "C" math adopted,
|
||||
including the use of builtins.
|
||||
- updates and configure/build work to support new libtool
|
||||
- addition of strstream
|
||||
- valarray work
|
||||
- complex work
|
||||
- update to SGI STL 3.3
|
||||
- libio sync between glibc/libstdc++-v3. Some divergence since initial
|
||||
merge, but sources remain quite close.
|
||||
- IO fixes for alpha
|
||||
- wide character work for IO when using libio
|
||||
- addition of c_io_stdio and "C" IO abstraction layer.
|
||||
- auto_ptr fixes, testsuite additions
|
||||
- Attempts to use -ffunction-sections -fdata-sections and
|
||||
--gc-sections, depending on use of GNU ld and specific features. As of
|
||||
late, --gc-sections has been disabled due to problems with it throwing
|
||||
away initialization sections. This work is ongoing.
|
||||
- long double support
|
||||
- sub directory removal, coherent organization of cpu and os-specific
|
||||
files, consolidation of include directories, integration of the C++
|
||||
support bits for operator new/delete,exceptions, etc. All includes
|
||||
are now either in the include/* hierarchy or in libsupc++'s sub directory.
|
||||
- Support for more platforms, including irix and bsd variants.
|
||||
- filebuf tweaks to deal with variable-size buffers.
|
||||
- filebuf implementation for putbackc, etc. al.
|
||||
- ctype rewritten. Includes ctype<char>, ctype<wchar_t>, and others.
|
||||
- codecvt rewritten. Includes codecvt<char, char, mbstate_t>,
|
||||
codecvt<wchar_t, char, mbstate_t>. In addition,
|
||||
implementation-defined conversions using iconv are now supported with
|
||||
the __enc_traits partial-specialization of the State template
|
||||
parameter of the codecvt class. In this manner, conversions between
|
||||
encodings such as UCS4, USC2, UNICODE, UNICODEBIG, UNICODELITTLE, etc
|
||||
can be performed.
|
||||
- preliminary work on named locales
|
||||
- preliminary documentation for locale implementation has been established.
|
||||
- Many, many bug fixes.
|
||||
- Many, many testsuite additions and consistent VERIFY usage.
|
||||
- work on mkcheck to make it more flexible, use libtool, etc.
|
||||
- preliminary doxygen documentation has been added. Running "make
|
||||
doxygen" in the libstdc++-v3 build directory will generate HTML
|
||||
documentation that can be used to cross-reference names and files in
|
||||
the library.
|
||||
- a dejagnu based testing framework has been added
|
||||
- a new implementation of the concept checking code has been ported
|
||||
from the boost libraries.
|
||||
- support for -fno-exceptions has been added
|
||||
- stdexcept was re-written
|
||||
- using deprecated or antiquated headers now gives a warning
|
||||
- the stdio interface to iostreams has been tweaked, and now works
|
||||
with synchronized c/c++ io
|
||||
- new libsupc++ routines implementing the IA-64 C++ ABI.
|
||||
- HPUX configuration files
|
||||
- support for AIX added
|
||||
- a lot of bugs were fixed.
|
||||
- preliminary named locales implemented
|
||||
- portability improvements made to generation of <limits>
|
||||
- speedups to improve configuration time.
|
||||
- DJGPP support added.

- support for dlopening shared libstdc++
