+Subject: [PATCH] test: fix incorrectly laid out instructions in issue11656.go
+
+CL 279423 introduced a regression in this test as it incorrectly laid
+out various instructions. In the case of arm, the second instruction
+was overwriting the first. In the case of 386, amd64 and s390x, the
+instructions were being appended to the end of the slice after 64
+zero bytes.
+
+This was causing test failures on "linux/s390x on z13".
+
+Fixes #44028
