From 3183f8ca304fd84096c44332f9bb699943beb6f1 Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Thu, 26 Apr 2018 16:52:34 -0300 Subject: perf symbols: Unify symbol maps Remove the split of symbol tables for data (MAP__VARIABLE) and for functions (MAP__FUNCTION), its unneeded and there were various places doing two lookups to find a symbol, so simplify this. We still will consider only the symbols that matched the filters in place, i.e. see the (elf_(sec,sym)|symbol_type)__filter() routines in the patch, just so that we consider only the same symbols as before, to reduce the possibility of regressions. All the tests on 50-something build environments, in varios versions of lots of distros and cross build environments were performed without build regressions, as usual with all pull requests the other tests were also performed: 'perf test' and 'make -C tools/perf build-test'. Also this was done at a great granularity so that regressions can be bisected more easily.
