      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: 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.

      perf hists browser: Fix event group display · d9ea48bc
      由 Namhyung Kim 提交于 
      Milian reported that the event group on TUI shows duplicated overhead.
This was due to a bug on calculating hpp->buf position.  The
hpp_advance() was called from __hpp__slsmg_color_printf() on TUI but
it's already called from the hpp__call_print_fn macro in __hpp__fmt().
The end result is that the print function returns number of bytes it
printed but the buffer advanced twice of the length.

This is generally not a problem since it doesn't need to access the
buffer again.  But with event group, overhead needs to be printed
multiple times and hist_entry__snprintf_alignment() tries to fill the
space with buffer after it printed.  So it (brokenly) showed the last
overhead again.

The bug was there from the beginning, but I think it's only revealed
when the alignment function was added.

      perf tools: Remove needless includes from cache.h · 175729fc
      由 Arnaldo Carvalho de Melo 提交于 
      The cache.h header doesn't use any of the definitions in some of the
headers it includes, ditch them and fix the fallout, where files were
getting stuff they needed just because they were including it, sometimes
not using what it really exports at all.

      tools: Introduce str_error_r() · c8b5f2c9
      由 Arnaldo Carvalho de Melo 提交于 
      The tools so far have been using the strerror_r() GNU variant, that
returns a string, be it the buffer passed or something else.

But that, besides being tricky in cases where we expect that the
function using strerror_r() returns the error formatted in a provided
buffer (we have to check if it returned something else and copy that
instead), breaks the build on systems not using glibc, like Alpine
Linux, where musl libc is used.

So, introduce yet another wrapper, str_error_r(), that has the GNU
interface, but uses the portable XSI variant of strerror_r(), so that
users rest asured that the provided buffer is used and it is what is
returned.
