From b9133bce0447bee9f5b4052c1467eb6908214acb Mon Sep 17 00:00:00 2001 From: Andreas Rheinhardt Date: Thu, 6 Oct 2022 00:53:01 +0200 Subject: [PATCH] avcodec/me_cmp: Mark ff_square_tab as hidden ff_square_tab is always used with an offset; if this table is marked as hidden, the compiler can infer that it and therefore also ff_square_tab + 256 have a fixed offset from the code. This allows to avoid performing "+ 256" at runtime by baking it into the offset from the code to the table.
