+Subject: [PATCH 030/157] [Backport][SME] aarch64: Commonise some folding code
+
+Reference: https://gcc.gnu.org/git/?p=gcc.git;a=commit;h=df99e9e42094dee0833ac38f53e7fae09b4d133c
+
+Add an aarch64_sve::gimple_folder helper for folding calls
+to integer constants.  SME will make more use of this.
+
+gcc/
+	* config/aarch64/aarch64-sve-builtins.h
+	(gimple_folder::fold_to_cstu): New member function.
+	* config/aarch64/aarch64-sve-builtins.cc
+	(gimple_folder::fold_to_cstu): Define.
+	* config/aarch64/aarch64-sve-builtins-base.cc
+	(svcnt_bhwd_impl::fold): Use it.
