This implements assembly support for the Memory Systems Extensions introduced as part of the Armv9.5-A architecture version. The changes include: * New subtarget feature for FEAT_TLBIW. * New system registers for FEAT_HDBSS: * HDBSSBR_EL2 and HDBSSPROD_EL2. * New system registers for FEAT_HACDBS: * HACDBSBR_EL2 and HACDBSCONS_EL2. * New TLBI instructions for FEAT_TLBIW: * VMALLWS2E1(nXS), VMALLWS2E1IS(nXS) and VMALLWS2E1OS(nXS). * New system register for FEAT_FGWTE3: * FGWTE3_EL3. >From 4f2834cd78430ac69418f307cb54e9e583c7c7fd Mon Sep 17 00:00:00 2001 From: Lucas Prates <lucas.pra...@arm.com> Date: Fri, 22 Dec 2023 12:05:26 +0000 Subject: [PATCH] [AArch64] Assembly support for the Armv9.5-A Memory System Extensions This implements assembly support for the Memory Systems Extensions introduced as part of the Armv9.5-A architecture version.
