    perf symbols: Unify symbol maps · 3183f8ca
    Arnaldo Carvalho de Melo authored
    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.
