Kevin Buettner df433d3162 Distinguish sentinel frame from null frame.
This patch replaces the `current_frame' static global in frame.c with
`sentinel_frame'.  It also makes the sentinel frame id unique and
different from the null frame.

By itself, there is not much point to this patch, but it makes
the code cleaner for the VALUE_FRAME_ID changes in another patch.
Since we now allow "navigation" to the sentinel frame, it removes
the necessity of adding special cases to other parts of GDB.

Note that a new function, get_next_frame_sentinel_okay, is introduced
in this patch.  It will be used by the VALUE_FRAME_ID changes that
I've made.

Thanks to Pedro Alves for this suggestion.

gdb/ChangeLog:

    	* frame.h (enum frame_id_stack_status): Add FID_STACK_SENTINEL.
    	(struct frame_id): Increase number of bits required for storing
    	stack status to 3 from 2.

Kevin Buettner 1a2f3d7ff1 Extend test gdb.python/py-recurse-unwind.exp
This patch modifies the unwinder (sniffer) defined in
py-recurse-unwind.py so that, depending upon the value of one of its
class variables, it will take different paths through the code,
testing different functionality.

The original test attempted to obtain the value of an undefined
symbol.

This somewhat expanded test checks to see if 'pc' can be read via
gdb.PendingFrame.read_register() and also via gdb.parse_and_eval().

gdb/testsuite/ChangeLog:

	* gdb.python/py-recurse-unwind.c (main): Add loop.
	* gdb.python/py-recurse-unwind.py (TestUnwinder): Add calls
	to read_register() and gdb.parse_and_eval().  Make each code
	call a separate case that can be individually tested.
	* gdb.python/py-recurse-unwind.exp (cont_and_backtrace): New
	proc. Call cont_and_backtrace for each of the code paths that
	we want to test in the unwinder.

Senthil Kumar Selvaraj 4cb771f214 Fix PR20789 - relaxation with negative valued diff relocs
Fix issues with diff relocs that have a negative value
i.e. sym2 - sym1 where sym2 is lesser than sym1.

The assembler generates a diff reloc with symbol as start of section
and addend as sym2 offset, and encodes assembly time difference at
the reloc offset.

The existing relaxation logic adjusts addends if the relaxed insn lies
between symbol and addend. That doesn't work for diff relocs where
sym2 is less than sym1 *and* the relaxed insn happens to be between
sym2 and sym1.

Fix the problems by

1. Using signed handling of the difference value (bfd_signed_vma instead
of bfd_vma, bfd_{get,set}_signed_xxx instead of bfd_{get,set}_xxx).

2. Not assuming sym2 is bigger than sym1. It instead computes the actual
addresses and sets the lower and higher addresses as start and end
addresses respectively and then sees if insn is between start and end.

3. Creating a new function elf32_avr_adjust_reloc_if_spans_insn to
centralize reloc adjustment, and ensuring diff relocs get adjusted
correctly even if their sym + addend doesn't overlap a relaxed insn.

It also removes a redundant variable did_pad. It is never set if
did_shrink is TRUE, and the code does a early return if did_shrink is
FALSE.

Pedro Alves 4c62b19fd2 gdb: update gnulib to pull in C++ namespace support fixes
I've been experimenting with making use of gnulib's C++ namespace support:

 https://www.gnu.org/software/gnulib/manual/html_node/A-C_002b_002b-namespace-for-gnulib.html

That stumbled on a few gnulib issues, which I've fixed upstream:

 [PATCH] Fix gnulib C++ namespace support and std::frexp
 https://lists.gnu.org/archive/html/bug-gnulib/2016-11/msg00039.html

 [PATCH] Fix real-floating argument functions in C++ mode

 [PATCH] C++: "#define timeval rpl_timeval" -> typedef in GNULIB_NAMESPACE

Pedro Alves 5cc8c73103 Delete gdb::unique_ptr/gdb::move
Now that we require C++11 and all uses of gdb::unique_ptr and
gdb::move are gone, let's remove their definitions...

With my lazy hat on, I repurposed the header for "generally useful
unique_ptr specializations", and left gdb::unique_xmalloc_ptr in
there.  Not sure whether we it'd be better move it out of the gdb
namespace or leave it be.  I left it because it's less work and avoids
disrupting yet-unmerged patches that use it.

Andreas Arnez b7f38fdae7 bitfield-parent-optimized-out: Fix struct definition
The "struct S" type in bitfield-parent-optimized-out.exp is declared to
have a size of 4 bytes but to hold two 4-byte members: an int-based
bitfield and a 4-byte int.  Also, both members have the same
data_member_location 2, causing them to overlap and to reach 2 bytes
beyond the structure's boundary.

This is fixed by increasing the structure size to 8 and setting the
first and second member's data_member_location to 0 and 4, respectively.

Markus Metzger db58b3735f btrace: read entire aux buffer
The data_head of a perf event data buffer grows indefinitely.  Users are
expected to compute data_head % data_size to find the location inside the perf
event data buffer.

The aux_head of a perf event aux buffer wraps around and always stays within the
perf event aux buffer.

Well, at least that's the behaviour for BTS and PT - where BTS uses the data
buffer and PT the aux buffer.

GDB does not read beyond data_head or aux_head.  This is OK for BTS but wrong
for PT.  It causes only a portion of the trace to be considered by GDB.  In the
extreme case, the buffer may appear (almost) empty.

Thanks to Tim Wiederhake  <tim.wiederhake@intel.com> for reporting the anomaly.

Change it to read the entire aux buffer for PT.  The buffer is initially zero so
any extra zeroes we read before aux_head wraps around the first time will be
ignored when searching for the first PSB packet in order to synchronize onto the
trace stream.

	* nat/linux-btrace.c (perf_event_read): Allow data_head < size.
	* nat/linux-btrace.c (perf_event_read_all): Do not adjust size.

Mike Frysinger 91588b3af8 sim: mips: fix dv-tx3904cpu build error
When building for mipstx39-rtems4.12 targets, some funcs use SD and CPU
implicitly.  Restore the defines for these to the local sd and cpu vars.

This was broken by the clean up in commit d47f5b30d8.

Tom Tromey 9b9720149d Use unique_xmalloc_ptr in Python code
This changes some utility functions in the Python code to return
unique_xmalloc_ptr, and then fixes up the callers.

I chose unique_xmalloc_ptr rather than std::string because at a few
call points the xmalloc'd string is released and ownership transferred
elsewhere.

This patch found a few existing memory leaks.  For example,
py-unwind.c called gdbpy_obj_to_string but never freed the result.

Built and regression tested on the buildbot.

H.J. Lu 60227d64dd X86: Remove the .s suffix from EVEX vpextrw
The .s suffix indicates that the instruction is encoded by swapping
2 register operands.  Since vpextrw takes an XMM register and an
integer register, the .s suffix should be ignored for EVEX vpextrw.

Pedro Alves fad0c9fb7d Further cleanup/modernization of gdb.base/commands.exp
- Use multi_line for matching multi-line GDB output.

 - Add a multi_line_input variant of multi_line to build GDB input and
   use it throughout.

   (The two changes above make the tests much more readable, IMO.)

 - Add a new valnum_re global to get rid of the multiple "\\\$\[0-9\]*".

 - Remove gdb_stop_suppressing_tests uses.

 - tighten a few regexps.

 - Replace send_gdb/gdb_expect with gdb_test_multiple and simplify,
   making pass/fail messages the same.
