From b8cbb349061edda648463b086cfa869a7ab583af Mon Sep 17 00:00:00 2001 From: Wang Nan Date: Fri, 26 Feb 2016 09:31:51 +0000 Subject: perf config: Bring perf_default_config to the very beginning at main() Before this patch each subcommand calls perf_config() by themself, reading the default configuration together with subcommand specific options. If a subcommand doesn't have it own options, it needs to call 'perf_config(perf_default_config, NULL)' to ensure .perfconfig is loaded. This patch brings perf_config(perf_default_config, NULL) to the very start of main(), so subcommands don't need to do it. After this patch, 'llvm.clang-path' works for 'perf trace'.
