From a1229109dec4375259d3fff99f362405aab7917a Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Mon, 24 Feb 2020 17:28:46 +0000 Subject: target/arm: Implement v8.4-RCPC The v8.4-RCPC extension implements some new instructions: * LDAPUR, LDAPURB, LDAPURH, LDAPRSB, LDAPRSH, LDAPRSW * STLUR, STLURB, STLURH These are all in a new subgroup of encodings that sits below the top-level "Loads and Stores" group in the Arm ARM. The STLUR* instructions have standard store-release semantics; the LDAPUR* have Load-AcquirePC semantics, but (as with LDAPR*) we choose to implement them as the slightly stronger Load-Acquire.
