Fix copy_bitwise()

When the user writes or reads a variable whose location is described
with DWARF pieces (DW_OP_piece or DW_OP_bit_piece), GDB's helper
function copy_bitwise is invoked for each piece.  The implementation of
this function has a bug that may result in a corrupted copy, depending
on alignment and bit size.  (Full-byte copies are not affected.)

This rewrites copy_bitwise, replacing its algorithm by a fixed version,
and adding an appropriate test case.  Without the fix the new test case
fails, e.g.:

  print def_t
  $2 = {a = 0, b = 4177919}
  (gdb) FAIL: gdb.dwarf2/nonvar-access.exp: print def_t

Written in binary, the wrong result above looks like this:

  01111111011111111111111

Which means that two zero bits have sneaked into the copy of the
original all-one bit pattern.  The test uses this simple all-one value
in order to avoid another GDB bug that causes the DWARF piece of a
DW_OP_stack_value to be taken from the wrong end on big-endian
architectures.

Pedro Alves [Wed, 23 Nov 2016 15:36:26 +0000 (15:36 +0000)]
gdb: Use C++11 std::chrono

This patch fixes a few problems with GDB's time handling.

#1 - It avoids problems with gnulib's C++ namespace support

On MinGW, the struct timeval that should be passed to gnulib's
gettimeofday replacement is incompatible with libiberty's
timeval_sub/timeval_add.  That's because gnulib also replaces "struct
timeval" with its own definition, while libiberty expects the
system's.

E.g., in code like this:

  gettimeofday (&prompt_ended, NULL);
  timeval_sub (&prompt_delta, &prompt_ended, &prompt_started);
  timeval_add (&prompt_for_continue_wait_time,
               &prompt_for_continue_wait_time, &prompt_delta);

That's currently handled in gdb by not using gnulib's gettimeofday at
all (see common/gdb_sys_time.h), but that #undef hack won't work with
if/when we enable gnulib's C++ namespace support, because that mode
adds compile time warnings for uses of ::gettimeofday, which are hard
errors with -Werror.

#2 - But there's an elephant in the room: gettimeofday is not monotonic...

We're using it to:

  a) check how long functions take, for performance analysis
  b) compute when in the future to fire events in the event-loop
  c) print debug timestamps

But that's exactly what gettimeofday is NOT meant for.  Straight from
the man page:

~~~
       The time returned by gettimeofday() is affected by
       discontinuous jumps in the system time (e.g., if the system
       administrator manually changes the system time).  If you need a
       monotonically increasing clock, see clock_gettime(2).
~~~

std::chrono (part of the C++11 standard library) has a monotonic clock
exactly for such purposes (std::chrono::steady_clock).  This commit
switches to use that instead of gettimeofday, fixing all the issues
mentioned above.

7 years agoMakefiles: Flatten and sort file lists
Simon Marchi [Tue, 22 Nov 2016 21:14:22 +0000 (16:14 -0500)]
Makefiles: Flatten and sort file lists

I find the big file lists in the Makefiles a bit ugly and not very
practical.  Since there are multiple filenames on each line (as much as
fits in 80 columns), it's not easy to add, remove or change a name in
the middle.  As a result, we have a mix of long and short lines in no
particular order (ALL_TARGET_OBS is a good example).

I therefore suggest flattening the lists (one name per line) and keeping
them in alphabetical order.  The diffs will be much clearer and merge
conflicts will be easier to resolve.

A nice (IMO) side-effect I observed is that the files are compiled
alphabetically by make, so it gives a rough idea of the progress of the
build.

I added a comment in gdb/Makefile.in to mention to keep the file lists
ordered, and gave the general guidelines on what order to respect.  I
added a comment in other Makefiles which refers to gdb/Makefile.in, to
avoid duplication.

Running the patch through the buildbot found that gdb.base/default.exp
started to fail.  The languages in the error message shown when typing
"set language" have changed order.  We could probably improve gdb so
that it prints them in a stable order, regardless of the order of the
object list passed to the linked, but just fixing the test is easier for
now.

New in v2:

 - Change ordering style, directories go at the end.
 - Cleanup gdbserver's and data-directory's Makefile as well.
 - Add comments at top of Makefiles about the ordering.
 - Remove wrong trailing backslahes.
 - Fix test gdb.base/default.exp.

   {standard input}:1: Warning: architecture bumped from "v6" to "v9m" on "mwait"
   {standard input}:1: Error: Hardware capability "sparc5" not enabled for "wr".

... and it should'nt, as WRMCDPER pertains to the same architecture
level than MWAIT.

This patch fixes this by extending the definition of sparc opcode
architectures to contain a set of hardware capabilities and making the
assembler to take these capabilities into account when updating the
set of allowed hwcaps when an architecture bump is triggered by some
instruction.

This way, hwcaps associated to architecture levels are maintained in
opcodes, while the assembler keeps the flexibiity of defining GAS
architectures including additional hwcaps (like -Asparcfmaf or the
v8plus* variants).

A test covering this failure case is included.

Create subobject value in pretty printer

Nowadays, we create a value of subobject in pretty printer with 'address'
being used,

  value = value_from_contents_and_address (type, valaddr + embedded_offset,
   address + embedded_offset);

value_from_contents_and_address creates a value from memory, but the
value we are pretty-printing may not from memory at all.

Instead of using value_from_contents_and_address, we create a value
of subobject with the same location as object's but different offset.
We avoid using address in this way.  As a result, parameter 'address'
in apply_val_pretty_printer is no longer needed, we can remove it in
next step.

We've already had the location of the 'whole' value, so it is safe
to assume we can create a value of 'component' or 'suboject' value
at the same location but with different offset.
