Subject: [FFmpeg-devel] [PATCH 1/5] configure: Add detection of RISC-V vector intrinsic support
Date: Tue, 9 May 2023 17:50:26 +0800
Message-ID: <20230509095030.25506-2-arnie.chang@sifive.com> (raw)
In-Reply-To: <20230509095030.25506-1-arnie.chang@sifive.com>
Check whether the toolchain has support for RISC-V intrinsic and then
update the flag, HAVE_INTRINSICS_RVV, in the config.h
