[Qemu-devel] [PATCH v2 01/29] target/riscv: Move CPURISCVState pointer to DisasContext |
Date: |
Sat, 20 Oct 2018 09:14:23 +0200 |
CPURISCVState is rarely used, so there is no need to pass it to every
translate function. This paves the way for decodetree which only passes
DisasContext to translate functions.
