[Qemu-devel] [PATCH v1 5/8] RISC-V: Add priv_ver to DisasContext


From: Alistair Francis
Subject: [Qemu-devel] [PATCH v1 5/8] RISC-V: Add priv_ver to DisasContext
Date: Mon, 14 Jan 2019 23:58:32 +0000

The gen methods should access state from DisasContext. Add priv_ver
field to the DisasContext struct.
