The latest MTE specification adds register Xt to the STG instruction family: STG [Xn, #offset] -> STG Xt, [Xn, #offset] The tag written to memory is taken from Xt rather than Xn. Also, the LDG instruction also was changed to read return address from Xt: LDG Xt, [Xn, #offset]. This patch includes those changes and tests. Specification is at: https://developer.arm.com/docs/ddi0596/c Differential Revision: https://reviews.llvm.org/D60188 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@357583 91177308-0d34-0410-b5e6-96231b3b80d8
