+Subject: [PATCH 123/157] [Backport][SME] aarch64: Skip some SME register save
+ tests on BE
+
+Reference: https://gcc.gnu.org/git/?p=gcc.git;a=commit;h=23ea0bc2cf042d74c4adfe26a57cf96b1d837a91
+
+Big-endian targets need to save Z8-Z15 in the same order as
+the registers would appear for D8-D15, because the layout is
+mandated by the EH ABI.  BE targets therefore use ST1D instead
+of the normal STR for those registers (but not for others).
+
+That difference is already tested elsewhere and isn't important
+for the SME tests.  This patch therefore restricts the affected
+tests to LE.
+
+gcc/testsuite/
+	* gcc.target/aarch64/sme/call_sm_switch_5.c: Restrict tests that
+	contain Z8-Z23 saves to little-endian.
+	* gcc.target/aarch64/sme/call_sm_switch_8.c: Likewise.
+	* gcc.target/aarch64/sme/locally_streaming_1.c: Likewise.
