Subject: [PATCH] amd/addrlib: Use signed char for INT_8.
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

Some architectures like aarch64 and ppc64el have char = unisgned char.
This breaks meta equation generation for DCC coords, as addrlib tries
to filter all the Z bits > -1 which ends up being all the Z bits > 255.
