From b933720be22442e6847629fe0dcf24b95cef3d56 Mon Sep 17 00:00:00 2001 From: Daniel Henrique Barboza Date: Tue, 26 Sep 2023 15:31:08 -0300 Subject: [PATCH] target/riscv: add riscv_cpu_get_name() We'll introduce generic errors that will output a CPU type name via its RISCVCPU pointer. Create a helper for that. Use the helper in tcg_cpu_realizefn() instead of hardcoding the 'host' CPU name.
