Subject: [PATCH 11/19] target/riscv: remove cpu->cfg.ext_s
Date: Mon, 27 Mar 2023 09:42:39 -0300 [thread overview]
Message-ID: <20230327124247.106595-12-dbarboza@ventanamicro.com> (raw)
In-Reply-To: <20230327124247.106595-1-dbarboza@ventanamicro.com>
Create a new "s" RISCVCPUMisaExtConfig property that will update
env->misa_ext* with RVS. Instances of cpu->cfg.ext_s and similar are
replaced with riscv_has_ext(env, RVS).
Remove the old "s" property and 'ext_s' from RISCVCPUConfig.
