+    Commit: See in git+ssh://linaroci@gcc.gnu.org/git/gcc.git
+    commit gcc-16-4045-gab6879f3e997

+    Date:   Mon Sep 22 17:29:21 2025 +0100
+    
+        arm: fix target-specific test duplicates for gcc
+        
+        This patch fixes all the duplicates that I see when testing GCC (C
+        code).  Some of these were real problems with the testsuite where we
+        were testing the wrong thing because of typos; others are due to
+    ... 26 lines of the commit log omitted.
