Subject: [PATCH 09/19] target/riscv: remove cpu->cfg.ext_e
Date: Mon, 27 Mar 2023 09:42:37 -0300 [thread overview]
Message-ID: <20230327124247.106595-10-dbarboza@ventanamicro.com> (raw)
In-Reply-To: <20230327124247.106595-1-dbarboza@ventanamicro.com>
Create a new "e" RISCVCPUMisaExtConfig property that will update
env->misa_ext* with RVE. Instances of cpu->cfg.ext_e and similar are
replaced with riscv_has_ext(env, RVE).
Remove the old "e" property and 'ext_e' from RISCVCPUConfig.
