+Subject: [PATCH] Darwin: Darwin 20 is to be macOS 11 (Big Sur).
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+As per Nigel Tufnel's assertion "... this one goes to 11".
+
+The various parts of the code that deal with mapping Darwin versions
+to macOS (X) versions need updating to deal with  a major version of
+11.
+
+So now we have, for example:
+
+Darwin  4 => macOS (X) 10.0
+…
+Darwin 14 => macOS (X) 10.10
+...
+Darwin 19 => macOS (X) 10.15
+
+Darwin 20 => macOS  11.0
+
+Because of the historical duplication of the "10" in macOSX 10.xx and
+the number of tools that expect this, it is likely that system tools will
+allow macos11.0 and/or macosx11.0 (despite that the latter makes little
+sense).
+
+Update the link test to cover Catalina (Darwin19/10.15) and
+Big Sur (Darwin20/11.0).
+
+gcc/ChangeLog:
+
+	* config/darwin-c.c: Allow for Darwin20 to correspond to macOS 11.
+	* config/darwin-driver.c: Likewise.
+
+gcc/testsuite/ChangeLog:
+
+	* gcc.dg/darwin-minversion-link.c: Allow for Darwin19 (macOS 10.15)
+	and Darwin20 (macOS 11.0).
