Subject: H-mode no longer exists
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=f87cdfec1dd79afdabccc848e730d780589b8a65;p=riscv-isa-sim.git

H-mode no longer exists

It's supplanted by the hypervisor extension, which doesn't use the privilege
encoding of 2; it still looks like supervisor (i.e. 1).
