Subject: [musl] [PATCH 08/14] riscv: Fall back to syscall __riscv_flush_icache
Date: Thu, 3 Sep 2020 07:23:03 -0400 [thread overview]
Message-ID: <20200903112309.102601-9-sorear@fastmail.com> (raw)
In-Reply-To: <20200903112309.102601-1-sorear@fastmail.com>
Matches glibc behavior and fixes a case where we could fall off the
function without returning a value.
