<a name="index-implementation_002ddefined-behavior_002c-C_002b_002b-language"></a>
|
|
|
|
<p>A conforming implementation of ISO C++ is required to document its
|
|
choice of behavior in each of the areas that are designated
|
|
“implementation defined”. The following lists all such areas,
|
|
along with the section numbers from the ISO/IEC 14882:1998 and ISO/IEC
|
|
14882:2003 standards. Some areas are only implementation-defined in
|
|
one version of the standard.
|
|
</p>
|
|
<p>Some choices depend on the externally determined ABI for the platform
|
|
(including standard character encodings) which GCC follows; these are
|
|
listed as “determined by ABI” below. See <a href="Compatibility.html#Compatibility">Binary
|
|
Compatibility</a>, and <a href="http://gcc.gnu.org/readings.html">http://gcc.gnu.org/readings.html</a>. Some
|
|
choices are documented in the preprocessor manual.
|
|
See <a href="http://gcc.gnu.org/onlinedocs/cpp/Implementation_002ddefined-behavior.html#Implementation_002ddefined-behavior">Implementation-defined
|
|
behavior</a> in <cite>The C Preprocessor</cite>. Some choices are documented in
|
|
the corresponding document for the C language. See <a href="C-Implementation.html#C-Implementation">C Implementation</a>. Some choices are made by the library and operating
|
|
system (or other environment when compiling for a freestanding
|
|
environment); refer to their documentation for details.
