From 82c70b08dfb47bf56ce78fbd9147d38f51ecdeb8 Mon Sep 17 00:00:00 2001 From: Kyrylo Tkachov Date: Tue, 5 Jan 2021 17:39:04 +0000 Subject: aarch64: Remove support for CSRE This patch removes support for the CSRE extension from aarch64 gas/objdump. CSRE (FEAT_CSRE) is part of the Future Architecture Technologies program and at this time Arm is withdrawing this particular feature. The patch removes the system registers and the CSR PDEC instruction. gas/ChangeLog * NEWS: Remove CSRE. * config/tc-aarch64.c (parse_csr_operand): Delete.
