Subject: [MPlayer-dev-eng] [PATCH] add initial RISC-V support
Message-ID: <YP3sRkdCQW7lOxqd@humpty.home.comstyle.com>

OpenBSD only supports riscv64 but this is an attempt at adding
some of the initial bits for RISC-V support.

Given you can test only 64 bit and everyone else is dropping 32-bit
support left and right is all this extra code really justifiable
compared to just assuming 64 bit?
