&lt;h1&gt;GCC 13 Release Series&lt;br&gt;Changes, New Features, and Fixes&lt;/h1&gt;

&lt;p&gt;
This page is a &quot;brief&quot; summary of some of the huge number of improvements
in GCC 13.
You may also want to check out our
&lt;a href=&quot;porting_to.html&quot;&gt;Porting to GCC 13&lt;/a&gt; page and the
&lt;a href=&quot;../onlinedocs/index.html#current&quot;&gt;full GCC documentation&lt;/a&gt;.
&lt;/p&gt;

&lt;!-- .................................................................. --&gt;
&lt;h2&gt;Caveats&lt;/h2&gt;
&lt;ul&gt;
    &lt;li&gt;OpenMP offloading to Intel MIC has been removed.&lt;/li&gt;
    &lt;li&gt;The support for the &lt;code&gt;cr16-elf&lt;/code&gt;, &lt;code&gt;tilegx*-linux&lt;/code&gt;, &lt;code&gt;tilepro*-linux&lt;/code&gt;,
      &lt;code&gt;hppa[12]*-*-hpux10*&lt;/code&gt;, &lt;code&gt;hppa[12]*-*-hpux11*&lt;/code&gt;
      and &lt;code&gt;m32c-rtems&lt;/code&gt; configurations has been removed.&lt;/li&gt;
    &lt;li&gt;Support for Solaris 11.3 (&lt;code&gt;*-*-solaris2.11.3&lt;/code&gt;) has been
      declared obsolete.  The next release of GCC will have corresponding
      code permanently &lt;strong&gt;removed&lt;/strong&gt;.  Details can be found in
      the
      &lt;a href=&quot;https://gcc.gnu.org/pipermail/gcc/2022-December/240322.html&quot;&gt;
      announcement&lt;/a&gt;.
    &lt;/li&gt;
    &lt;li&gt;Support for emitting the STABS debugging format (including the
      &lt;code&gt;-gstabs&lt;/code&gt; and &lt;code&gt;-gxcoff&lt;/code&gt; options) has been removed.
      (This means the &lt;strong&gt;dbx&lt;/strong&gt; debugger is no longer
      supported, either.)&lt;/li&gt;
    &lt;li&gt;Legacy debug info compression option &lt;code&gt;-gz=zlib-gnu&lt;/code&gt; was removed
      and the option is ignored right now.&lt;/li&gt;
    &lt;li&gt;&lt;a href=&quot;https://gcc.gnu.org/onlinedocs/gcc-13.1.0/gcc/Warning-Options.html#index-Warray-bounds&quot;&gt;&lt;code&gt;-Warray-bounds=2&lt;/code&gt;&lt;/a&gt;
      will no longer issue warnings for out of
      bounds accesses to trailing struct members of one-element array type
      anymore. Instead it diagnoses accesses to trailing arrays according to
      &lt;code&gt;-fstrict-flex-arrays&lt;/code&gt;. &lt;/li&gt;
    &lt;li&gt;&lt;a href=&quot;https://gcc.gnu.org/onlinedocs/gcc-13.1.0/gcc/Static-Analyzer-Options.html&quot;&gt;&lt;code&gt;-fanalyzer&lt;/code&gt;&lt;/a&gt;
      is still only suitable for analyzing C code.
      In particular, using it on C++ is unlikely to give meaningful output.&lt;/li&gt;
    &lt;li&gt;In the arm port, support for the iWMMXt extensions, enabled through
      &lt;code&gt;-mcpu=iwmmxt&lt;/code&gt;, has been deprecated and will be removed in a
      future release.  This includes support for the
      &lt;a href=&quot;https://gcc.gnu.org/onlinedocs/gcc-13.1.0/gcc/ARM-iWMMXt-Built-in-Functions.html&quot;&gt;
      iWMMXt built-in functions&lt;/a&gt;.
    &lt;/li&gt;
&lt;/ul&gt;


&lt;!-- .................................................................. --&gt;
&lt;h2 id=&quot;general&quot;&gt;General Improvements&lt;/h2&gt;

&lt;ul&gt;
  &lt;li id=&quot;openmp&quot;&gt;&lt;a href=&quot;https://gcc.gnu.org/projects/gomp/&quot;&gt;OpenMP&lt;/a&gt;
  &lt;ul&gt;
    &lt;li&gt;
      Reverse offload is now supported with AMD GCN and nvptx devices.
      Additionally, the &lt;code&gt;requires&lt;/code&gt; handling has been improved and
      all clauses are now accepted. If a requirement cannot be fulfilled for
      an accessible device, this device is excluded from the list of
      available devices. This may imply that the only device left is the host
      (the initial device).
      In particular, &lt;code&gt;unified_address&lt;/code&gt; and
      &lt;code&gt;unified_shared_memory&lt;/code&gt; are unsupported by all non-host
      devices.
    &lt;/li&gt;
    &lt;li&gt;
      OpenMP 5.0: Fortran now supports some non-rectangular loop nests; for
      C/C++, the support was added in GCC 11.
    &lt;/li&gt;
    &lt;li&gt;
      The following OpenMP 5.1 features have been added: the
      &lt;code&gt;omp_all_memory&lt;/code&gt; reserved locator, the &lt;code&gt;inoutset&lt;/code&gt;
      modifier to the &lt;code&gt;depend&lt;/code&gt; clause, the &lt;code&gt;nowait&lt;/code&gt;
      clause for the &lt;code&gt;taskwait&lt;/code&gt; directive and the
      &lt;code&gt;omp_target_is_accessible&lt;/code&gt;, &lt;code&gt;omp_target_memcpy_async&lt;/code&gt;,
      &lt;code&gt;omp_target_memcpy_rect_async&lt;/code&gt; and
      &lt;code&gt;omp_get_mapped_ptr&lt;/code&gt; API routines. The &lt;code&gt;assume&lt;/code&gt; and
      &lt;code&gt;assumes&lt;/code&gt; directives, the &lt;code&gt;begin/end declare target&lt;/code&gt;
      syntax in C/C++ and device-specific ICV settings with environment variables
      are now supported.&lt;/li&gt;
    &lt;li&gt;
      Initial support for OpenMP 5.2 features has been added:
      &lt;code&gt;firstprivate&lt;/code&gt; and &lt;code&gt;allocate&lt;/code&gt; clauses on the
      &lt;code&gt;scope&lt;/code&gt; construct; the OpenMP 5.2 syntax of the
      &lt;code&gt;linear&lt;/code&gt; clause; new enum/constants
      &lt;code&gt;omp_initial_device&lt;/code&gt; and &lt;code&gt;omp_invalid_device&lt;/code&gt;; and
      optionally omitting the map-type in &lt;code&gt;target enter/exit data&lt;/code&gt;.
      The &lt;code&gt;enter&lt;/code&gt; clause (as alias for &lt;code&gt;to&lt;/code&gt;) has been added
      to the &lt;code&gt;declare target&lt;/code&gt; directive. Also added have been the
      &lt;code&gt;omp_in_explicit_task&lt;/code&gt; routine and the &lt;code&gt;doacross&lt;/code&gt;
      clause as alias for &lt;code&gt;depend&lt;/code&gt; with
      &lt;code&gt;source&lt;/code&gt;/&lt;code&gt;sink&lt;/code&gt; modifier.
    &lt;/li&gt;
    &lt;li&gt;
      The &lt;code&gt;_ALL&lt;/code&gt; suffix to the device-scope environment variables
      added in Technical Report (TR11) is already handled.
    &lt;/li&gt;
    &lt;li&gt;
      For user defined allocators requesting high bandwidth or large capacity
      memspaces or interleaved partitioning, the &lt;a
      href=&quot;http://memkind.github.io/memkind/&quot;&gt;memkind&lt;/a&gt; library is used,
      if available at run time.
    &lt;/li&gt;
  &lt;/ul&gt;
  &lt;/li&gt;
  &lt;li&gt;
    AddressSanitizer defaults to &lt;code&gt;detect_stack_use_after_return=1&lt;/code&gt; on GNU/Linux targets.
    For compatibility, it can be disabled with &lt;code&gt;env ASAN_OPTIONS=detect_stack_use_after_return=0&lt;/code&gt;.
  &lt;/li&gt;
  &lt;li&gt;New debug info compression option value &lt;code&gt;-gz=zstd&lt;/code&gt; has been added.&lt;/li&gt;
  &lt;li&gt;
    Link-time optimization improvements:
    &lt;ul&gt;
        &lt;li&gt;LTO supports the newly added jobserver of GNU make jobserver that uses named pipes (&lt;code&gt;--jobserver-style=fifo&lt;/code&gt;)
        by default.&lt;/li&gt;
        &lt;li&gt;If make's jobserver is active, parallel LTO WPA streaming communicates with it and thus avoids
            system overcommitting.&lt;/li&gt;
    &lt;/ul&gt;
  &lt;/li&gt;
  &lt;li&gt;&lt;code&gt;-Ofast&lt;/code&gt;, &lt;code&gt;-ffast-math&lt;/code&gt; and &lt;code&gt;-funsafe-math-optimizations&lt;/code&gt;
      will no longer add startup code to alter the floating-point environment
      when producing a shared object with &lt;code&gt;-shared&lt;/code&gt;.
  &lt;/li&gt;
  &lt;li&gt;
    GCC can now emit its diagnostics using &lt;a href=&quot;https://sarifweb.azurewebsites.net/&quot;&gt;SARIF&lt;/a&gt;.
    This is a JSON-based format suited for capturing the results of static
    analysis tools (like GCC's &lt;a href=&quot;https://gcc.gnu.org/onlinedocs/gcc-13.1.0/gcc/Static-Analyzer-Options.html&quot;&gt;&lt;code&gt;-fanalyzer&lt;/code&gt;&lt;/a&gt;),
    but it can also be used to capture other GCC warnings and errors in a
    machine-readable format.
    Specifically, the &lt;a href=&quot;https://gcc.gnu.org/onlinedocs/gcc-13.1.0/gcc/Diagnostic-Message-Formatting-Options.html#index-fdiagnostics-format&quot;&gt;&lt;code&gt;-fdiagnostics-format=&lt;/code&gt;&lt;/a&gt;
    option has been extended to support these new values:
    &lt;ul&gt;
      &lt;li&gt;&lt;code&gt;-fdiagnostics-format=sarif-stderr&lt;/code&gt;&lt;/li&gt;
      &lt;li&gt;&lt;code&gt;-fdiagnostics-format=sarif-file&lt;/code&gt;&lt;/li&gt;
      &lt;li&gt;&lt;code&gt;-fdiagnostics-format=json-stderr&lt;/code&gt;, a synonym for the
	existing &lt;code&gt;-fdiagnostics-format=json&lt;/code&gt;&lt;/li&gt;
      &lt;li&gt;&lt;code&gt;-fdiagnostics-format=json-file&lt;/code&gt;&lt;/li&gt;
    &lt;/ul&gt;
    where the &lt;code&gt;json&lt;/code&gt;-prefixed variants refer to GCC's own JSON diagnostic format.
  &lt;/li&gt;
&lt;/ul&gt;


&lt;!-- .................................................................. --&gt;
&lt;h2 id=&quot;languages&quot;&gt;New Languages and Language specific improvements&lt;/h2&gt;

&lt;h3 id=&quot;ada&quot;&gt;Ada&lt;/h3&gt;
&lt;ul&gt;
  &lt;li&gt;Traceback support added in RTEMS for the PPC ELF and ARM architectures.&lt;/li&gt;
  &lt;li&gt;Support for versions older than VxWorks 7 has been removed.&lt;/li&gt;
  &lt;li&gt;General improvements to the contracts in the standard libraries.&lt;/li&gt;
  &lt;li&gt;Addition of &lt;code&gt;GNAT.Binary_Search&lt;/code&gt;.&lt;/li&gt;
  &lt;li&gt;Further additions and fixes for the Ada 2022 specification.&lt;/li&gt;
  &lt;li&gt;The Pragma &lt;code&gt;SPARK_Mode=&amp;gt;Auto&lt;/code&gt; is now accepted. Contract analysis has been further improved.&lt;/li&gt;
  &lt;li&gt;Documentation improvements.&lt;/li&gt;
&lt;/ul&gt;

&lt;h3 id=&quot;c-family&quot;&gt;C family&lt;/h3&gt;
&lt;ul&gt;
  &lt;li&gt;New warnings:
    &lt;ul&gt;
      &lt;li&gt;&lt;a href=&quot;https://gcc.gnu.org/onlinedocs/gcc-13.1.0/gcc/Warning-Options.html#index-Wxor-used-as-pow&quot;&gt;&lt;code&gt;-Wxor-used-as-pow&lt;/code&gt;&lt;/a&gt;
	warns about uses of &lt;code&gt;^&lt;/code&gt;, the exclusive or operator,
	where it appears the user meant exponentiation
	(&lt;a href=&quot;https://gcc.gnu.org/PR90885&quot;&gt;PR90885&lt;/a&gt;)&lt;/li&gt;
    &lt;/ul&gt;
  &lt;/li&gt;
  &lt;li&gt;Three new function attributes for documenting &lt;code&gt;int&lt;/code&gt; arguments that are file descriptors:
    &lt;ul&gt;
      &lt;li&gt;&lt;a href=&quot;https://gcc.gnu.org/onlinedocs/gcc-13.1.0/gcc/Common-Function-Attributes.html#index-fd_005farg-function-attribute&quot;&gt;&lt;code&gt;__attribute__((fd_arg(N)))&lt;/code&gt;&lt;/a&gt;&lt;/li&gt;
      &lt;li&gt;&lt;a href=&quot;https://gcc.gnu.org/onlinedocs/gcc-13.1.0/gcc/Common-Function-Attributes.html#index-fd_005farg_005fread-function-attribute&quot;&gt;&lt;code&gt;__attribute__((fd_arg_read(N)))&lt;/code&gt;&lt;/a&gt;&lt;/li&gt;
      &lt;li&gt;&lt;a href=&quot;https://gcc.gnu.org/onlinedocs/gcc-13.1.0/gcc/Common-Function-Attributes.html#index-fd_005farg_005fwrite-function-attribute&quot;&gt;&lt;code&gt;__attribute__((fd_arg_write(N)))&lt;/code&gt;&lt;/a&gt;&lt;/li&gt;
    &lt;/ul&gt;
    These are used by
    &lt;a href=&quot;https://gcc.gnu.org/onlinedocs/gcc-13.1.0/gcc/Static-Analyzer-Options.html&quot;&gt;&lt;code&gt;-fanalyzer&lt;/code&gt;&lt;/a&gt;
    to detect misuses of file descriptors.
  &lt;/li&gt;
  &lt;li&gt;A new statement attribute for C++23 &lt;a href=&quot;https://wg21.link/p1774r8&quot;&gt;P1774R8&lt;/a&gt; Portable
      assumptions support also in C or older C++:
      &lt;a href=&quot;https://gcc.gnu.org/onlinedocs/gcc-13.1.0/gcc/Statement-Attributes.html#index-assume-statement-attribute&quot;&gt;&lt;code&gt;__attribute__((assume(EXPR)));&lt;/code&gt;&lt;/a&gt;
  &lt;/li&gt;
 &lt;li&gt;GCC can now control when to treat the trailing array of a structure as a
     flexible array member for the purpose of accessing the elements of such
     an array. By default, all trailing arrays in aggregates are treated as
     flexible array members. Use the new command-line option
     &lt;a href=&quot;https://gcc.gnu.org/onlinedocs/gcc-13.1.0/gcc/Warning-Options.html#index-Wstrict-flex-arrays&quot;&gt;&lt;code&gt;-fstrict-flex-arrays&lt;/code&gt;&lt;/a&gt;
     to control which array members are treated as flexible arrays.
 &lt;/li&gt;
&lt;/ul&gt;

&lt;h3 id=&quot;c&quot;&gt;C&lt;/h3&gt;
&lt;ul&gt;
  &lt;li&gt;Several C23 features have been implemented:
    &lt;ul&gt;
      &lt;li&gt;&lt;a href=&quot;https://www.open-std.org/jtc1/sc22/wg14/www/docs/n3042.htm&quot;&gt;N3042&lt;/a&gt;,
	  Introduce the nullptr constant&lt;/li&gt;
      &lt;li&gt;&lt;a href=&quot;https://www.open-std.org/jtc1/sc22/wg14/www/docs/n2963.htm&quot;&gt;N2963&lt;/a&gt;,
      Enhanced Enumerations (fixed underlying types)&lt;/li&gt;
      &lt;li&gt;&lt;a href=&quot;https://www.open-std.org/jtc1/sc22/wg14/www/docs/n2975.pdf&quot;&gt;N2975&lt;/a&gt;,
	Relax requirements for variadic parameter lists&lt;/li&gt;
      &lt;li&gt;&lt;a href=&quot;https://www.open-std.org/jtc1/sc22/wg14/www/docs/n3007.htm&quot;&gt;N3007&lt;/a&gt;,
      Type inference for object definitions (&lt;code&gt;auto&lt;/code&gt;)&lt;/li&gt;
      &lt;li&gt;&lt;a href=&quot;https://www.open-std.org/jtc1/sc22/wg14/www/docs/n3018.htm&quot;&gt;N3018&lt;/a&gt;,
	The &lt;code&gt;constexpr&lt;/code&gt; specifier for object definitions&lt;/li&gt;
      &lt;li&gt;&lt;a href=&quot;https://www.open-std.org/jtc1/sc22/wg14/www/docs/n3038.htm&quot;&gt;N3038&lt;/a&gt;,
	Introduce storage-class specifiers for compound literals&lt;/li&gt;
      &lt;li&gt;&lt;code&gt;typeof&lt;/code&gt; (previously supported as an extension)
	and &lt;code&gt;typeof_unqual&lt;/code&gt;&lt;/li&gt;
      &lt;li&gt;New
	keywords &lt;code&gt;alignas&lt;/code&gt;, &lt;code&gt;alignof&lt;/code&gt;, &lt;code&gt;bool&lt;/code&gt;,
	&lt;code&gt;false&lt;/code&gt;, &lt;code&gt;static_assert&lt;/code&gt;, &lt;code&gt;thread_local&lt;/code&gt;,
	&lt;code&gt;true&lt;/code&gt;&lt;/li&gt;
      &lt;li&gt;&lt;a href=&quot;https://www.open-std.org/jtc1/sc22/wg14/www/docs/n2764.pdf&quot;&gt;N2764&lt;/a&gt;,
      The &lt;code&gt;noreturn&lt;/code&gt; attribute&lt;/li&gt;
      &lt;li&gt;Support for empty initializer braces&lt;/li&gt;
      &lt;li&gt;&lt;code&gt;__STDC_VERSION_*_H__&lt;/code&gt; header version macros&lt;/li&gt;
      &lt;li&gt;Removal of &lt;code&gt;ATOMIC_VAR_INIT&lt;/code&gt;&lt;/li&gt;
      &lt;li&gt;&lt;code&gt;unreachable&lt;/code&gt; macro
      in &lt;code&gt;&amp;lt;stddef.h&amp;gt;&lt;/code&gt;&lt;/li&gt;
      &lt;li&gt;Removal of trigraphs&lt;/li&gt;
      &lt;li&gt;Removal of unprototyped functions&lt;/li&gt;
      &lt;li&gt;&lt;code&gt;printf&lt;/code&gt; and &lt;code&gt;scanf&lt;/code&gt; format checking
      with &lt;a href=&quot;https://gcc.gnu.org/onlinedocs/gcc-13.1.0/gcc/Warning-Options.html#index-Wformat&quot;&gt;&lt;code&gt;-Wformat&lt;/code&gt;&lt;/a&gt; for &lt;code&gt;%wN&lt;/code&gt;
      and &lt;code&gt;%wfN&lt;/code&gt; format length modifiers&lt;/li&gt;
      &lt;li&gt;&lt;a href=&quot;https://www.open-std.org/jtc1/sc22/wg14/www/docs/n2836.pdf&quot;&gt;N2836&lt;/a&gt;,
	Identifier Syntax using Unicode Standard Annex 31&lt;/li&gt;
    &lt;/ul&gt;
  &lt;/li&gt;
  &lt;li&gt;In addition to those C23 features, existing features adopted in
  C23 have been adjusted to follow C23 requirements and are not diagnosed
  with &lt;code&gt;-std=c2x -Wpedantic&lt;/code&gt;.&lt;/li&gt;
  &lt;li&gt;New warnings:
    &lt;ul&gt;
      &lt;li&gt;&lt;a href=&quot;https://gcc.gnu.org/onlinedocs/gcc-13.1.0/gcc/Warning-Options.html#index-Wenum-int-mismatch&quot;&gt;&lt;code&gt;-Wenum-int-mismatch&lt;/code&gt;&lt;/a&gt;
	 warns about mismatches between an enumerated type and an integer type
	  (&lt;a href=&quot;https://gcc.gnu.org/PR105131&quot;&gt;PR105131&lt;/a&gt;)&lt;/li&gt;
    &lt;/ul&gt;
  &lt;/li&gt;
&lt;/ul&gt;

&lt;h3 id=&quot;cxx&quot;&gt;C++&lt;/h3&gt;
&lt;ul&gt;
  &lt;li&gt;Excess precision support (which has been available in C since GCC 4.5)
      has been implemented for C++ as well.  It is enabled by default
      in strict standard modes like &lt;code&gt;-std=c++17&lt;/code&gt;, where it
      defaults to &lt;code&gt;-fexcess-precision=standard&lt;/code&gt;, while in GNU
      standard modes like &lt;code&gt;-std=gnu++20&lt;/code&gt; it defaults to
      &lt;code&gt;-fexcess-precision=fast&lt;/code&gt;.  The option mainly affects
      IA-32/x86-64 using x87 math and in some cases on Motorola 68000,
      where &lt;code&gt;float&lt;/code&gt; and &lt;code&gt;double&lt;/code&gt; expressions
      are evaluated in &lt;code&gt;long double&lt;/code&gt; precision and S/390, System z,
      IBM z Systems where &lt;code&gt;float&lt;/code&gt; expressions are evaluated in
      &lt;code&gt;double&lt;/code&gt; precision.  Also, on several architectures where
      &lt;code&gt;std::float16_t&lt;/code&gt; or &lt;code&gt;std::bfloat16_t&lt;/code&gt; types
      are supported those are evaluated in &lt;code&gt;float&lt;/code&gt; precision.
      &lt;code&gt;-fexcess-precision=fast&lt;/code&gt; restores previous behavior.
  &lt;/li&gt;
  &lt;li&gt;Several C++23 features have been implemented:
    &lt;ul&gt;
      &lt;li&gt;&lt;a href=&quot;https://wg21.link/p2324&quot;&gt;P2324R1&lt;/a&gt;, Labels at the end of
	  compound statements (&lt;a href=&quot;https://gcc.gnu.org/PR103539&quot;&gt;PR103539&lt;/a&gt;)
      &lt;/li&gt;
      &lt;li&gt;&lt;a href=&quot;https://wg21.link/p2255&quot;&gt;P2255R2&lt;/a&gt;, A type trait to detect
	  reference binding to temporary
	  (&lt;a href=&quot;https://gcc.gnu.org/PR104477&quot;&gt;PR104477&lt;/a&gt;)
      &lt;/li&gt;
      &lt;li&gt;&lt;a href=&quot;https://wg21.link/p2327&quot;&gt;P2327R1&lt;/a&gt;, De-deprecating volatile

    &lt;/li&gt;
    &lt;li&gt;Additions to the &lt;code&gt;&amp;lt;algorithm&amp;gt;&lt;/code&gt; header:

&lt;/ul&gt;

&lt;h3 id=&quot;go&quot;&gt;Go&lt;/h3&gt;

&lt;ul&gt;
  &lt;li&gt;GCC 13, like GCC 12, provides a complete implementation of the
    Go 1.18 user packages.&lt;/li&gt;
  &lt;li&gt;Although Go 1.18 includes support for generic programming, that
    support is not yet available in GCC.&lt;/li&gt;
&lt;/ul&gt;

&lt;h3 id=&quot;modula2&quot;&gt;Modula-2&lt;/h3&gt;
&lt;ul&gt;
  &lt;li&gt;Support for the language Modula-2 has been added.  This includes
    support for the ISO/IEC 10514-1, PIM2, PIM3, PIM4 dialects
    together with a complete set of ISO/IEC 10514-1 and PIM
    libraries.&lt;/li&gt;
  &lt;li&gt;The &lt;code&gt;&amp;lt;* noreturn *&amp;gt;&lt;/code&gt; attribute is supported
    with the &lt;code&gt;-Wreturn-type&lt;/code&gt;

&lt;h3 id=&quot;aarch64&quot;&gt;AArch64&lt;/h3&gt;
&lt;ul&gt;
  &lt;li&gt;The AArch64 target now supports Decimal Floating-point in the BID format
      through the &lt;code&gt;libbid&lt;/code&gt; library.&lt;/li&gt;
  &lt;li&gt;A number of new CPUs are supported through the &lt;code&gt;-mcpu&lt;/code&gt; and
  &lt;code&gt;-mtune&lt;/code&gt; options (GCC identifiers in parentheses).
    &lt;ul&gt;
      &lt;li&gt;Ampere-1A (&lt;code&gt;ampere1a&lt;/code&gt;).&lt;/li&gt;
      &lt;li&gt;Arm Cortex-A715 (&lt;code&gt;cortex-a715&lt;/code&gt;).&lt;/li&gt;
      &lt;li&gt;Arm Cortex-X1C (&lt;code&gt;cortex-x1c&lt;/code&gt;).&lt;/li&gt;
      &lt;li&gt;Arm Cortex-X3 (&lt;code&gt;cortex-x3&lt;/code&gt;).&lt;/li&gt;
      &lt;li&gt;Arm Neoverse V2 (&lt;code&gt;neoverse-v2&lt;/code&gt;).&lt;/li&gt;
    &lt;/ul&gt;
  &lt;li&gt;Support has been added for the &lt;code&gt;armv9.1-a, armv9.2-a&lt;/code&gt; and
      &lt;code&gt;armv9.3-a&lt;/code&gt; arguments to the &lt;code&gt;-march=&lt;/code&gt; option.&lt;/li&gt;
  &lt;li&gt;The &lt;code&gt;FEAT_LRCPC&lt;/code&gt; feature is now supported by generating the
      &lt;code&gt;LDAPR&lt;/code&gt; instructions for C and C++ atomic loads with an
      acquire memory model.  This is enabled when compiling with the
      &lt;code&gt;+rcpc&lt;/code&gt; extension to &lt;code&gt;-march&lt;/code&gt; or a CPU target that
      supports this feature.&lt;/li&gt;
  &lt;li&gt;The &lt;code&gt;FEAT_CSSC&lt;/code&gt; feature from the 2022 Arm Architecture
      extensions is supported through the &lt;code&gt;+cssc&lt;/code&gt; extension option.
      When enabled, scalar operations like integer minimum, maximum, absolute
      value, count trailing zeroes (&lt;code&gt;__builtin_ctz&lt;/code&gt;), population
      count (&lt;code&gt;__builtin_popcount&lt;/code&gt;) can be implemented in a
      single instruction.&lt;/li&gt;
  &lt;li&gt;The &lt;code&gt;FEAT_LSE2&lt;/code&gt; feature is now supported through
      &lt;code&gt;libatomic&lt;/code&gt; and provides lockless 16-byte atomics on systems
      that implement it.&lt;/li&gt;
&lt;/ul&gt;

&lt;h3 id=&quot;amdgcn&quot;&gt;AMD Radeon (GCN)&lt;/h3&gt;
&lt;ul&gt;
  &lt;li&gt;Support for the Instinct MI200 series devices (&lt;a
      href=&quot;https://gcc.gnu.org/onlinedocs/gcc-13.1.0/gcc/AMD-GCN-Options.html&quot;&gt;
      &lt;code&gt;gfx90a&lt;/code&gt;&lt;/a&gt;) has been added.&lt;/li&gt;
  &lt;li&gt;SIMD vectorization support has been improved; this and stack-handling
      changes &lt;a
      href=&quot;https://gcc.gnu.org/install/specific.html#amdgcn-x-amdhsa&quot;&gt;require&lt;/a&gt;

&lt;/ul&gt;

&lt;!-- &lt;h3 id=&quot;arc&quot;&gt;ARC&lt;/h3&gt; --&gt;

&lt;h3 id=&quot;arm&quot;&gt;arm&lt;/h3&gt;
&lt;ul&gt;
  &lt;li&gt;A number of new CPUs are supported through the &lt;code&gt;-mcpu&lt;/code&gt; and
  &lt;code&gt;-mtune&lt;/code&gt; options (GCC identifiers in parentheses).
    &lt;ul&gt;
      &lt;li&gt;STAR-MC1 (&lt;code&gt;star-mc1&lt;/code&gt;).&lt;/li&gt;
      &lt;li&gt;Arm Cortex-X1C (&lt;code&gt;cortex-x1c&lt;/code&gt;).&lt;/li&gt;
      &lt;li&gt;Arm Cortex-M85 (&lt;code&gt;cortex-m85&lt;/code&gt;).&lt;/li&gt;
    &lt;/ul&gt;
  &lt;/li&gt;
  &lt;li&gt;Support has been added for the M-profile PACBTI extension that can help
      harden the generated code against return-oriented and
      jump-oriented attacks.  It can be enabled through the
      &lt;code&gt;-mbranch-protection=&lt;/code&gt; option.
  &lt;/li&gt;
&lt;/ul&gt;

&lt;!-- &lt;h3 id=&quot;avr&quot;&gt;AVR&lt;/h3&gt; --&gt;

&lt;h3 id=&quot;x86&quot;&gt;IA-32/x86-64&lt;/h3&gt;
&lt;ul&gt;
  &lt;li&gt;For both C and C++ the &lt;code&gt;__bf16&lt;/code&gt; type is supported on
      x86 systems with SSE2 and above enabled.
  &lt;/li&gt;
  &lt;li&gt;Use real &lt;code&gt;__bf16&lt;/code&gt; type for AVX512BF16 intrinsics. Previously
  we use __bfloat16 which is typedef of short. Now we introduced real
  &lt;code&gt;__bf16&lt;/code&gt; type to x86 psABI. Users need to adjust their
  AVX512BF16-related source code when upgrading GCC12 to GCC13.
  &lt;/li&gt;
  &lt;li&gt;New ISA extension support for Intel AVX-IFMA was added.
      AVX-IFMA intrinsics are available via the &lt;code&gt;-mavxifma&lt;/code&gt;
      compiler switch.
  &lt;/li&gt;
  &lt;li&gt;New ISA extension support for Intel AVX-VNNI-INT8 was added.
      AVX-VNNI-INT8 intrinsics are available via the &lt;code&gt;-mavxvnniint8&lt;/code&gt;
      compiler switch.
  &lt;/li&gt;
  &lt;li&gt;New ISA extension support for Intel AVX-NE-CONVERT was added.
      AVX-NE-CONVERT intrinsics are available via the
      &lt;code&gt;-mavxneconvert&lt;/code&gt; compiler switch.
  &lt;/li&gt;
  &lt;li&gt;New ISA extension support for Intel CMPccXADD was added.
      CMPccXADD intrinsics are available via the &lt;code&gt;-mcmpccxadd&lt;/code&gt;
      compiler switch.
  &lt;/li&gt;
  &lt;li&gt;New ISA extension support for Intel AMX-FP16 was added.
      AMX-FP16 intrinsics are available via the &lt;code&gt;-mamx-fp16&lt;/code&gt;
      compiler switch.
  &lt;/li&gt;
  &lt;li&gt;New ISA extension support for Intel PREFETCHI was added.
      PREFETCHI intrinsics are available via the &lt;code&gt;-mprefetchi&lt;/code&gt;
      compiler switch.
  &lt;/li&gt;
  &lt;li&gt;New ISA extension support for Intel RAO-INT was added.
      RAO-INT intrinsics are available via the &lt;code&gt;-mraoint&lt;/code&gt;
      compiler switch.
  &lt;/li&gt;
  &lt;li&gt;New ISA extension support for Intel AMX-COMPLEX was added.
      AMX-COMPLEX intrinsics are available via the &lt;code&gt;-mamx-complex&lt;/code&gt;
      compiler switch.
  &lt;/li&gt;
  &lt;li&gt;GCC now supports the Intel CPU named Raptor Lake through
    &lt;code&gt;-march=raptorlake&lt;/code&gt;.
    Raptor Lake is based on Alder Lake.
  &lt;/li&gt;
  &lt;li&gt;GCC now supports the Intel CPU named Meteor Lake through
    &lt;code&gt;-march=meteorlake&lt;/code&gt;.
    Meteor Lake is based on Alder Lake.
  &lt;/li&gt;
  &lt;li&gt;GCC now supports the Intel CPU named Sierra Forest through
    &lt;code&gt;-march=sierraforest&lt;/code&gt;.
    The switch enables the AVX-IFMA, AVX-VNNI-INT8, AVX-NE-CONVERT and
    CMPccXADD ISA extensions.
  &lt;/li&gt;
  &lt;li&gt;GCC now supports the Intel CPU named Grand Ridge through
    &lt;code&gt;-march=grandridge&lt;/code&gt;.
    The switch enables the AVX-IFMA, AVX-VNNI-INT8, AVX-NE-CONVERT, CMPccXADD
    and RAO-INT ISA extensions.
  &lt;/li&gt;
  &lt;li&gt;GCC now supports the Intel CPU named Emerald Rapids through
    &lt;code&gt;-march=emeraldrapids&lt;/code&gt;.
    Emerald Rapids is based on Sapphire Rapids.
  &lt;/li&gt;
  &lt;li&gt;GCC now supports the Intel CPU named Granite Rapids through
    &lt;code&gt;-march=graniterapids&lt;/code&gt;.
    The switch enables the AMX-FP16, PREFETCHI and AMX-COMPLEX ISA extensions.
  &lt;/li&gt;
  &lt;li&gt;GCC now supports AMD CPUs based on the &lt;code&gt;znver4&lt;/code&gt; core
    via &lt;code&gt;-march=znver4&lt;/code&gt;.  The switch makes GCC consider
    using 512 bit vectors when auto-vectorizing.
  &lt;/li&gt;
&lt;/ul&gt;

&lt;h3 id=&quot;loongarch&quot;&gt;LoongArch&lt;/h3&gt;
&lt;ul&gt;
  &lt;li&gt;New features
    &lt;ul&gt;
      &lt;li&gt;The new command-line option &lt;code&gt;-mexplicit-relocs&lt;/code&gt; decides whether
	  to use the assembler relocation operator when dealing with symbolic addresses.
	  It is enabled by default if a compatible assembler (binutils 2.40 or later)
	  is present at GCC build time.
      &lt;/li&gt;
      &lt;li&gt;The new command-line option &lt;code&gt;-mdirect-extern-access&lt;/code&gt; can be used
	  to prevent accessing external symbols through GOT.
      &lt;/li&gt;
      &lt;li&gt;The new variable attribute &lt;a href=&quot;https://gcc.gnu.org/onlinedocs/gcc/LoongArch-Variable-Attributes.html#LoongArch-Variable-Attributes&quot;&gt;&lt;code&gt;model&lt;/code&gt;&lt;/a&gt;
          has been added.
      &lt;/li&gt;
    &lt;/ul&gt;
  &lt;/li&gt;
  &lt;li&gt;Built-in functions
    &lt;ul&gt;
      &lt;li&gt;The &lt;code&gt;rint&lt;/code&gt; and &lt;code&gt;copysign&lt;/code&gt; mathematical builtins
          (and their float variants) are now implemented as inline LoongArch intrinsics.
      &lt;/li&gt;

    such as from coding standards documents, or specifications.
    Such rules have a code name and can have a URL, which GCC can print
    in text form or capture in its
