From 4b838b0db4e9cb3892b181ea9adc13cefb90d210 Mon Sep 17 00:00:00 2001 From: Jiri Olsa Date: Fri, 17 Aug 2018 11:48:06 +0200 Subject: [PATCH] perf tools: Add compression id into 'struct kmod_path' Store a decompression ID in 'struct kmod_path', so it can be later stored in 'struct dso'. Switch 'struct kmod_path's 'comp' from 'bool' to 'int' to return the compressions array index. Add 0 index item into compressions array, so that the comp usage stays as it was: 0 - no compression, != 0 compression index. Update the kmod_path tests. Committer notes: Use a designated initializer + terminating comma, e.g. { .fmt = NULL, }, to fix the build in several distros: centos:6: util/dso.c:201: error: missing initializer centos:6: util/dso.c:201: error: (near initialization for 'compressions[0].decompress') debian:9: util/dso.c:201:24: error: missing field 'decompress' initializer [-Werror,-Wmissing-field-initializers] fedora:25: util/dso.c:201:24: error: missing field 'decompress' initializer [-Werror,-Wmissing-field-initializers] fedora:26: util/dso.c:201:24: error: missing field 'decompress' initializer [-Werror,-Wmissing-field-initializers] fedora:27: util/dso.c:201:24: error: missing field 'decompress' initializer [-Werror,-Wmissing-field-initializers] oraclelinux:6: util/dso.c:201: error: missing initializer oraclelinux:6: util/dso.c:201: error: (near initialization for 'compressions[0].decompress') ubuntu:12.04.5: util/dso.c:201:2: error: missing initializer [-Werror=missing-field-initializers] ubuntu:12.04.5: util/dso.c:201:2: error: (near initialization for 'compressions[0].decompress') [-Werror=missing-field-initializers] ubuntu:16.04: util/dso.c:201:24: error: missing field 'decompress' initializer [-Werror,-Wmissing-field-initializers] ubuntu:16.10: util/dso.c:201:24: error: missing field 'decompress' initializer [-Werror,-Wmissing-field-initializers] ubuntu:16.10: util/dso.c:201:24: error: missing field 'decompress' initializer [-Werror,-Wmissing-field-initializers] ubuntu:17.10: util/dso.c:201:24: error: missing field 'decompress' initializer [-Werror,-Wmissing-field-initializers] Signed-off-by: Jiri Olsa Cc: Alexander Shishkin Cc: David Ahern Cc: Michael Petlan Cc: Namhyung Kim Cc: Peter Zijlstra Link: http://lkml.kernel.org/r/20180817094813.15086-7-jolsa@kernel.org Signed-off-by: Arnaldo Carvalho de Melo --- tools/perf/tests/kmod-path.c | 42 ++++++++++++++++++------------------ tools/perf/util/dso.c | 18 ++++++++++------ tools/perf/util/dso.h | 2 +- 3 files changed, 33 insertions(+), 29 deletions(-) diff --git a/tools/perf/tests/kmod-path.c b/tools/perf/tests/kmod-path.c index 148dd31cc201..f92f78f683ea 100644 --- a/tools/perf/tests/kmod-path.c +++ b/tools/perf/tests/kmod-path.c @@ -6,7 +6,7 @@ #include "debug.h" static int test(const char *path, bool alloc_name, bool alloc_ext, - bool kmod, bool comp, const char *name, const char *ext) + bool kmod, int comp, const char *name, const char *ext) { struct kmod_path m;
