Subject: [PATCH 2/2] riscv: Remove RV32 floating point functions
Date: Tue, 20 Sep 2022 15:21:13 -0400 [thread overview]
Message-ID: <f480d279d835b00a7edc03aa930f3e6c574ab000.1663702373.git.dj@redhat.com> (raw)
In-Reply-To: <cover.1663702373.git.dj@redhat.com>
We don't need RV32 specific floating point functions, instead make them
generic for RISC-V.
