From 7c689c839734a23eda855e69a56ed4795533bf71 Mon Sep 17 00:00:00 2001 From: Masami Hiramatsu Date: Mon, 22 Nov 2021 18:30:48 +0900 Subject: tools/perf: Add '__rel_loc' event field parsing support Add new '__rel_loc' dynamic data location attribute support. This type attribute is similar to the '__data_loc' but records the offset from the field itself. The libtraceevent adds TEP_FIELD_IS_RELATIVE to the 'tep_format_field::flags' with TEP_FIELD_IS_DYNAMIC for'__rel_loc'.
