+<h2>Further notes</h2>
+
+<ul>
+
+<li>cpp has limited support for multibyte character sets.</li>
+
+<li>IEC 60559 is IEEE 754 floating point. This works if and only if
+the hardware is perfectly compliant, but GCC does not define
+<code>__STDC_IEC_559__</code> or implement the associated standard
+pragmas; nor do some options such as <code>-frounding-math</code> to
+enable the pragmas globally work in all cases (for example, required
+exceptions may not be generated) and contracting expressions (e.g.,
+using fused multiply-add) is not restricted to source-language
+expressions as required by C99.</li>
+
+<li>Compiler support is needed for thorough support of <code>math_errhandling</code>; see
+messages <a
+href="http://sources.redhat.com/ml/libc-hacker/2000-06/msg00008.html">1</a>,
+<a
+href="http://sources.redhat.com/ml/libc-hacker/2000-06/msg00014.html">2</a>,
+<a

+on this subject to libc-hacker. The compiler needs to mark its output
+from compilations using <code>-fno-trapping-math</code>
+or <code>-fno-math-errno</code>, possibly using
+the <code>.gnu_attribute</code> mechanism, to indicate that built-in
+function optimizations may have been applied that mean that not all
+calls report error status in a particular way; the static linker
+needs to put this information in executables and shared libraries and
+the C library needs to use it to set <code>math_errhandling</code> at
+startup to a conservatively correct value based on the information
+from the compiler. There is currently some limited GNU C Library
+support that only conforms as long as the above options are not used
+anywhere in the program.</li>
+
+<li>GCC doesn't have <code>wprintf</code>, <code>wscanf</code> and
+<code>wcsftime</code> format checking support.</li>
+
+<li>GCC does not support the Annex G imaginary types and complex
+multiplication and division have excess overflows at runtime (although
+not beyond those permitted by C99).</li>
+
+<li><code><stdint.h></code> is provided by GCC, or fixed where
+the system headers provide a nonconforming version, on some but not
+yet all systems. On systems where types in this header have been
+defined as <code>char</code>, GCC retains this definition although it
+is not permitted by C99.</li>
+
+<li>Some of the C99 predefined macros represent properties of the
+compiler and library together and so defining them for the whole
+translation unit requires cooperation with the library;
+a <a href="http://sourceware.org/ml/libc-alpha/2009-04/msg00005.html">GNU
+C Library patch</a> for this is pending review.</li>
+
+<li><code>const</code>-qualified compound literals could share storage
+with each other and with string literals, but currently don't.</li>
+
+<li>The information provided by <code>static</code> in parameter array
+declarators is not used for optimization. It might make sense to use
+it in future in conjunction with <a href="../projects/prefetch.html">work
+on prefetching</a>.</li>
+
+<li>The list above differs from that in N1256 as follows:
+"LIA compatibility annex" is removed, since it refers to C99's
+conformance to another standard rather than something for C
+implementations to do. The <code><stdint.h></code> and
+<code><inttypes.h></code> entries have been separated, but are a
+single entry in C99.</li>

+<title>GCC 4.7 Release Criteria</title> </head>
+
+<body>
+
+<h1>GCC 4.7 Release Criteria</h1>
+
+<p>This page provides the release criteria for GCC 4.7.</p>
+
+<p>The GCC team (and, in particular, the Release Manager) will attempt
+to meet these criteria before the release of GCC 4.7.</p>
+
+<p>In all cases, these criteria represent the minimum functionality
+required in order to make the release. If this level of minimum
+functionality is not provided by a release candidate, then that
+candidate will probably not become the eventual release. However, a
+release candidate that does meet these criteria may not necessarily
+become the official release; there may be other unforeseen issues that
+prevent release. For example, if support for the Intel Pentium II is
+required by the release criteria, it is nevertheless unlikely that GCC
+would be released even though it did not support the Intel Pentium.</p>
+
+<p>Because the development of GCC is largely dependent on volunteers,
+the Release Manager and/or Steering Committee may eventually have to
+decide whether to make a release, even if the criteria here are not
+met. For example, if no volunteer can be found to verify correct
+operation of a particular application program on a particular system,
+then that criterion may be abandoned.</p>
+
+<h1>Languages</h1>
+
+<p>GCC supports several programming languages, including Ada, C, C++,
+Objective-C, Fortran, and Java. For the purposes of making releases,
+however, we will consider primarily C and C++, as those are the
+languages used by the vast majority of users. Therefore, if, below,
+the criteria indicate, for example, that there should be no DejaGNU
+regressions on a particular platform, that criteria should be read as
+applying only to DejaGNU regressions within the C, C++, and C++
+runtime library testsuites.</p>
+
+<h1>Primary and Secondary Platforms</h1>
+
+<p>GCC targets a vast number of platforms. We have classified these
+platforms into three categories: primary, secondary, and tertiary.
+Primary platforms are popular systems, both in the sense that there
+are many such systems in existence and in the sense that GCC is used
+frequently on those systems. Secondary platforms are also popular
+systems, but are either somewhat less popular than the primary
+systems, or are considered duplicative from a testing perspective.
+All platforms that are neither primary nor secondary are tertiary
+platforms.</p>
+
+<p>Our release criteria for primary platforms is:</p>
+<ul>
+
+<li>
+<p>All regressions open in Bugzilla have been analyzed, and all are
+deemed as either unlikely to affect most users, or are determined to
+have a minimal impact on affected users. For example, a
+typographical error in a diagnostic might be relatively common, but
+also has minimal impact on users.</p>
+
+<p>In general, regressions where the compiler generates incorrect
+code, or refuses to compile a valid program, will be considered to
+be sufficiently severe to block the release, unless there are
+substantial mitigating factors.</p>
+</li>
+
+<li>The DejaGNU testsuite has been run, and compared with a run of
+the testsuite on the previous release of GCC, and no regressions are
+observed.</li>
+</ul>
+
+<p>Our release criteria for the secondary platforms is:</p>
+<ul>
+<li>The compiler bootstraps successfully, and the C++ runtime library
+builds.</li>
+
+<li>The DejaGNU testsuite has been run, and a substantial majority of
+the tests pass.</li>
+</ul>
+
+<p>There are no release criteria for tertiary platforms.</p>
+
+<p>In contrast to previous releases, we have removed all mention of
+explicit application testing. It is our experience that, with the
+resources available, it is very difficult to methodically carry out
+such testing. However, we expect that interested users will submit
+bug reports for problems encountered building and using popular
+packages. Therefore, we do not intend the elimination of application
+testing from our criteria to imply that we will not pay attention to
+application testing.</p>

+
+<h1>Code Quality and Compilation Time</h1>
+
+<p>In addition to correctness issues (e.g., generating incorrect code,
+or issuing an invalid diagnostic, or refusing to compile valid code),
+we will also consider code quality (i.e., the speed with which the
+generated code executes) and compilation time (i.e., the speed with
+which the compiler executes).</p>
+
+<p>It is difficult, if not impossible, to set out specific criteria
+for determining what level of regression is acceptable for these issues.
+In contrast to most correctness issues, where nothing short of correct
+is acceptable, it is reasonable to trade off behavior for code quality
+and compilation time. For example, it may be acceptable, when
+compiling with optimization, if the compiler is slower, but generates
+superior code. It may also be acceptable for the compiler to generate
+inferior code on some test cases if it generates substantially
+superior code on other test cases. Therefore, the Release Manager, or
+parties to whom he or she delegates responsibility, will make
+determinations on a case-by-case basis as to whether or not a code
+quality or compilation time regression is sufficiently severe as to
+merit blocking the release.</p>
