@@ -30682,11 +30971,79 @@ For the effects of the @code{hot} attribute on functions, see
@section Function Multiversioning
@cindex function versions
-With the GNU C++ front end, for x86 targets, you may specify multiple
-versions of a function, where each function is specialized for a
-specific target feature. At runtime, the appropriate version of the
-function is automatically executed depending on the characteristics of
-the execution platform. Here is an example.
+Function multiversioning is a mechanism that enables compiling multiple
+versions of a function, each specialized for different combinations of
+architecture extensions. Additionally, the compiler generates a resolver that
+the dynamic linker uses to detect architecture support and choose the
+appropriate version at runtime.
+
+Function multiversioning relies on the indirect function extension to the ELF
+standard, and therefore Binutils version 2.20.1 or higher and GNU C Library
+version 2.11.1 are required to use this feature.
+
+There are two versions of function multiversioning supported by GCC.
+
+For targets supporting the @code{target_version} attribute (AArch64 and RISC-V),
+when compiling for C or C++, a function version set can be defined by a
+combination of function definitions with @code{target_version} and
+@code{target_clones} attributes, across translation units.
+
+For example:
+
+@smallexample
+// fmv.h:
+int foo ();
+int foo [[gnu::target_clones("sve", "sve2")]] ();
+int foo [[gnu::target_version("dotprod;priority=1")]] ();
+
+// fmv1.cc
+#include "fmv.h"
+
+int foo ()
+@{
+ // The default version of foo.
+ return 0;
+@}
+
+// fmv2.cc:
+#include "fmv.h"
+
+int foo [[gnu::target_clones("sve", "sve2")]] ()
+@{
+ // foo versions for sve and sve2
+ return 1;
+@}
+
+int foo [[gnu::target_version("dotprod")]] ()
+@{
+ // foo version for dotprod extension
+ return 2;
+@}
+
+// main.cc
+#include "fmv.h"
+
+int main ()
+@{
+ int (*p)() = &foo;
+ assert ((*p) () == foo ());
+ return 0;
+@}
+@end smallexample
+
+This example results in 4 versions of the foo function being generated, and
+a resolver which is used by the dynamic linker to choose the correct version.
+
+For the AArch64 target GCC implements function multiversionsing, with the
+semantics and version strings as specified in the
+@ref{ARM C Language Extensions (ACLE)}.
+
+For targets that support multiversioning with the @code{target} attribute
+(x86) a multiversioned function can be defined with either multiple function
+definitions with the @code{target} attribute (in C++) within a translation unit,
+or a single definition with the @code{target_clones} attribute.
+
+Here is an example.
