From 940fba68c903d9b4da2d99a68f1c06c53d4fe82a Mon Sep 17 00:00:00 2001 From: Brian Paul Date: Mon, 6 Nov 2017 18:11:38 -0700 Subject: [PATCH] util/tgsi: use ASSERT_BITFIELD_SIZE() to check opcode field size MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit I've noticed at least two places where we store the TGSI opcode in an unsigned:8 bitfield. We're at 249 opcodes now. If we hit 256 we'll need to grow those bitfields. Use the new ASSERT_BITFIELD_SIZE() macro to detect that.
