      perf annotate: Add per arch instructions annotate handlers · 763d8960
      Arnaldo Carvalho de Melo authored
      Another step in supporting cross annotation.
      
      The arch specific tables are put in:
      
         tools/perf/arch/$ARCH/annotation/instructions.c
      
      which, so far, just plug instructions to a bunch of parsers/formatters,
      but may have more as the need arises.
      
      This is an alternative implementation to a previous attempt made by Ravi
      Bangoria.

      perf annotate: Allow arches to specify functions to skip · 9c2fb451
      Arnaldo Carvalho de Melo authored
      This is to cope with an ARM specific kludge introduced in the original
      patch supporting ARM annotation, cfef25b8 ("perf annotate: ARM
      support") that made functions with a '+' in its name to be skipped when
      processing call instructions.
      
      With this patchkit it should be possible to collect a perf.data file on
      a ARM machine and then annotate it on a x86 workstation and have those
      ARM kludges used.

      perf annotate: Start supporting cross arch annotation · 786c1b51
      Arnaldo Carvalho de Melo authored
      Introduce a 'struct arch', where arch specific stuff will live, starting
      with objdump's choice of comment delimitation character, that is '#' in
      x86 while a ';' in arm.
      
      This has some bits and pieces from a patch submitted by Ravi.
