Date: Mon, 2 Mar 2020 10:53:53 +0530 From: Ravi Bangoria <ravi.bangoria@...ux.ibm.com> To: linuxppc-dev@...ts.ozlabs.org, linux-kernel@...r.kernel.org Cc: eranian@...gle.com, peterz@...radead.org, mpe@...erman.id.au, paulus@...ba.org, mingo@...hat.com, acme@...nel.org, mark.rutland@....com, alexander.shishkin@...ux.intel.com, jolsa@...hat.com, namhyung@...nel.org, adrian.hunter@...el.com, ak@...ux.intel.com, kan.liang@...ux.intel.com, alexey.budankov@...ux.intel.com, yao.jin@...ux.intel.com, robert.richter@....com, kim.phillips@....com, maddy@...ux.ibm.com, ravi.bangoria@...ux.ibm.com Subject: [RFC 09/11] perf annotate: Introduce type for annotation_line struct annotation_line can contain either assembly instruction or a source code line. To distinguish between them we currently use offset. If offset is -1, it's a source otherwise it's assembly. This is bit cryptic when you first read the code. Introduce new field 'type' that denotes type of the data the annotation_line object contains.
