Subject: [PATCH 15/22] target/riscv: th: make CSR insertion test a bit more intuitive
Date: Thu, 6 Feb 2025 19:27:03 +0100 [thread overview]
Message-ID: <20250206182711.2420505-16-pbonzini@redhat.com> (raw)
In-Reply-To: <20250206182711.2420505-1-pbonzini@redhat.com>
In preparation for generalizing the custom CSR functionality,
make the test return bool instead of int. Make the insertion_test
optional, too.
