From 98b860e3115ff937152dbf4c843e1ecb9244734c Mon Sep 17 00:00:00 2001 From: Sergii Romantsov Date: Mon, 2 Apr 2018 09:59:06 +0300 Subject: [PATCH] i965: Extend the negative 32-bit deltas to 64-bits Gen8+ use 48-bit address relocations so need to extend the sign to 64-bit return value. Without it we have higher bits zeroed and missing the negavive values. Haswell and older use 32-bit deltas so are unaffected by this issue. v2: used int32_t fucntion parameter instead of explicit type conversion.
