From 69ee49ac4678a60e2ae762b9f7752e61d27347c6 Mon Sep 17 00:00:00 2001 From: Andrii Simiklit Date: Tue, 13 Nov 2018 14:19:28 +0200 Subject: [PATCH] intel/tools: avoid 'unused variable' warnings MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit 1. tools/aub_read.c:271:31: warning: unused variable ‘end’ const uint32_t *p = data, *end = data + data_len, *next; 2. tools/aub_mem.c:292:13: warning: unused variable ‘res’ void *res = mmap((uint8_t *)bo.map + map_offset, 4096, PROT_READ, tools/aub_mem.c:357:13: warning: unused variable ‘res’ void *res = mmap((uint8_t *)bo.map + (page - bo.addr), 4096, PROT_READ, v2: The i965_disasm.c changes was moved into a separate patch The 'end' variable declared separately with MAYBE_UNUSED to avoid effect of it to other variables.
