From c8fa7a807f3c5f946bd92076fbaf7826edb650dc Mon Sep 17 00:00:00 2001 From: Solomon Tan Date: Fri, 22 Mar 2019 13:22:55 +0800 Subject: [PATCH] perf cs-etm: Add missing case value MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The following error was thrown when compiling `tools/perf` using OpenCSD v0.11.1. This patch fixes said error. CC util/intel-pt-decoder/intel-pt-log.o CC util/cs-etm-decoder/cs-etm-decoder.o util/cs-etm-decoder/cs-etm-decoder.c: In function ‘cs_etm_decoder__buffer_range’: util/cs-etm-decoder/cs-etm-decoder.c:370:2: error: enumeration value ‘OCSD_INSTR_WFI_WFE’ not handled in switch [-Werror=switch-enum] switch (elem->last_i_type) { ^~~~~~ CC util/intel-pt-decoder/intel-pt-decoder.o cc1: all warnings being treated as errors Because `OCSD_INSTR_WFI_WFE` case was added only in v0.11.0, the minimum required OpenCSD library version for this patch is no longer v0.10.0.
