From 878dd0e9ac18af657dcbdb598bb2eb1278606d3a Mon Sep 17 00:00:00 2001 From: Philipp Tomsich Date: Sat, 11 Sep 2021 16:00:04 +0200 Subject: [PATCH] target/riscv: Add x-zba, x-zbb, x-zbc and x-zbs properties The bitmanipulation ISA extensions will be ratified as individual small extension packages instead of a large B-extension. The first new instructions through the door (these have completed public review) are Zb[abcs]. This adds new 'x-zba', 'x-zbb', 'x-zbc' and 'x-zbs' properties for these in target/riscv/cpu.[ch].
