      perf annotate: Remove duplicate 'name' field from disasm_line · 75b49202
      由 Arnaldo Carvalho de Melo 提交于 
      The disasm_line::name field is always equal to ins::name, being used
just to locate the instruction's ins_ops from the per-arch instructions
table.

Eliminate this duplication, nuking that field and instead make
ins__find() return an ins_ops, store it in disasm_line::ins.ops, and
keep just in disasm_line::ins.name what was in disasm_line::name, this
way we end up not keeping a reference to entries in the per-arch
instructions table.

This in turn will help supporting multiple ways to manage the per-arch
instructions table, allowing resorting that array, for instance, when
the entries will move after references to its addresses were made. The
same problem is avoided when one grows the array with realloc.

So architectures simply keeping a constant array will work as well as
architectures building the table using regular expressions or other
logic that involves resorting the table.

      perf annotate: Add per arch instructions annotate handlers · 763d8960
      由 Arnaldo Carvalho de Melo 提交于 
      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
      由 Arnaldo Carvalho de Melo 提交于 
      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
      由 Arnaldo Carvalho de Melo 提交于 
      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.
