Fix silly ChangeLog entry in previous change.

Fix PR PR16445 - gdbserver build failure on x86.

If gdb_proc_service.h ends up including linux/elf.h, we'll trip on
duplicate definitions:

 In file included from ../../../gdb/gdbserver/linux-x86-low.c:29:0:
 ../../../gdb/gdbserver/../../include/elf/common.h:36:0: error: "ELFMAG0"
                 redefined [-Werror]
 ... etc ...

Handle this the same way linux-low.c and linux-arm-low.c handle this.

daily update

rearrange struct value to save memory

This patch rearranges struct value a tiny bit, moving the "regnum"
field into a hole.  This saves 8 bytes per value on a 64-bit machine,
and 4 bytes per value on a 32 bit machine.  I think it does not
negatively affect readability or performance.

Built and regtested on x86-64 Fedora 18.

2014-01-16  Tom Tromey  <tromey@redhat.com>

* value.c (struct value) <regnum>: Move earlier.

remove extended_remote_create_inferior_1

I noticed that extended_remote_create_inferior_1 is called from a
single spot.  This patch unifies the callee and caller.  It's just a
simple cleanup that made the coming refactoring simpler.

2014-01-16  Tom Tromey  <tromey@redhat.com>

* remote.c (extended_remote_create_inferior): Rename from
extended_remote_create_inferior_1.  Add "ops" argument.  Remove
old implementation.

Fix gdb.trace/mi-traceframe-changed.exp on s390.

The test fails on s390 with:

  -trace-find frame-number 0^M
  &"PC not available\n"^M
  ^done,found="1",tracepoint="1",traceframe="0",frame={level="-1",addr="<unavailable>",func="??",args=[]}^M
  (gdb) ^M
  FAIL: gdb.trace/mi-traceframe-changed.exp: tfile: -trace-find frame-number 0

tfile knows to infer the PC from the tracepoint's address if the PC
wasn't collected (tfile_fetch_registers) but, that only works on
targets whose PC register is a raw register, and on s390, the PC
register is a pseudo register.

But even if GDB doesn't know how to infer the value of PC, saying the
current frame is level -1 is a bug:

  ^done,found="1",tracepoint="1",traceframe="0",frame={level="-1",addr="<unavailable>",func="??",args=[]}^M
                                                       ^^^^^^^^^

'-1' is the level of the sentinel frame, which should never be visible.

This is caused by the s390's heuristic unwinder accepting the frame
(the fallback heuristic unwinders _always_ accept the frame), but then
the unwind->this_id method throws that "PC not available\n" error.

IOW, the s390's heuristic unwinder was never adjusted to handle
unavailable register values gracefully, which can happen with e.g., a
trimmed core file too.

This is just the minimal necessary for
<unavailable> frames, which at least gets us:

  (gdb) tfind
  Found trace frame 0, tracepoint 1
  #0  <unavailable> in ?? ()

That is, frame #0 instead of -1.

We could get better info out of "info frame" (this patch makes us show
"outermost"), but this change would still be necessary.

record-btrace: add (reverse-)stepping support

Provide to_resume and to_wait target methods for the btrace record target
to allow reverse stepping and replay support.

Replay is limited in the sense that only stepping and source correlation
are supported.  We do not record data and thus can not show variables.

Non-stop mode is not working.  Do not allow record-btrace in non-stop mode.

record-btrace: fix insn range in function call history

With the "/i" modifier, we print the instruction number range in the
"record function-call-history" command as [begin, end).

It would be more intuitive if we printed the range as [begin, end].

2014-01-16  Markus Metzger  <markus.t.metzger@intel.com>

* record-btrace.c (btrace_call_history_insn_range): Print
insn range as [begin, end].

btrace: change branch trace data structure

The branch trace is represented as 3 vectors:
  - a block vector
  - a instruction vector
  - a function vector

Each vector (except for the first) is computed from the one above.

Change this into a graph where a node represents a sequence of instructions
belonging to the same function and where we have three types of edges to connect
the function segments:
  - control flow
  - same function (instance)
  - call stack

This allows us to navigate in the branch trace.  We will need this for "record
goto" and reverse execution.

This patch introduces the data structure and computes the control flow edges.
It also introduces iterator structs to simplify iterating over the branch trace
in control-flow order.

It also fixes PR gdb/15240 since now recursive calls are handled correctly.
Fix the test that got the number of expected fib instances and also the
function numbers wrong.

The current instruction had been part of the branch trace.  This will look odd
once we start support for reverse execution.  Remove it.  We still keep it in
the trace itself to allow extending the branch trace more easily in the future.

test, btrace: update expected text

The error message for starting recording twice changed.
Update the expected text to fix resulting regressions.

2014-01-16  Markus Metzger  <markus.t.metzger@intel.com>

* gdb.btrace/enable.exp: Update expected text.

Fix testsuite/gdb.dwarf2/dw2-dos-drive.exp on ARM.

This test currently fails on ARM:

  (gdb) PASS: gdb.dwarf2/dw2-dos-drive.exp: set breakpoint pending off
  break 'z:file.c':func
  Cannot access memory at address 0x0

The error is GDB trying to read the prologue at the breakpoint's
address, and failing:

  38 throw_error() exceptions.c:444 0x0016728c
  37 memory_error() corefile.c:204 0x001d1fcc

      {
        inst = read_memory_unsigned_integer (skip_pc, 4, byte_order_for_code);

The test doesn't execute the compiled object's code, so GDB will try
to read memory from the binary's sections.  Instructions on ARM are
4-byte wide, and thus ARM's prologue scanner reads in 4-byte chunks.
As the section 'func' is put at is only 1 byte long, and no other
section is allocated contiguously:

  ...
  Sections:
  Idx Name          Size      VMA       LMA       File off  Algn
    0 .text         00000001  00000000  00000000  00000034  2**0
                    CONTENTS, ALLOC, LOAD, READONLY, CODE
  ...

... the exec target fails the read the 4 bytes.

Fix this by increasing the function's size.

Skip directories with LIBPATH_SUFFIX_SKIP suffix

On Linux/x86-64, when binutils is configured with --libdir=/usr/lib64,

puts /usr/lib64 in linker scripts for all emulations, like

/usr/lib6432 is odd and /usr/lib64 is wrong.  This patch changes

Tidy ld use of bfd_section userdata.

A long time ago ld made use of userdata to tie an output section to
its lang_input_statement_struct object file.  Some time later Joern
made map file printing of symbols at lot faster, using userdata on
input sections.  That complicated allocation of userdata, and when the
output section use disappeared a year later, the code wasn't properly
cleaned up.  This patch does that cleanup, and also tidies the symbol
printing code to not allocate userdata where it won't be needed.  We
don't print symbols defined in the absolute section or in output
sections.

move the "main" data into the per-BFD object

because once symbol sharing across objfiles is complete, computing the
main name as a side effect of symbol reading will no longer work --
the symbols simply won't be re-read.

Fix go32-nat.c build fallout from to_detach constification.

The recent constification of to_detach missed updating the forward
declaration of go32_detach, breaking the build:

 ../../src/gdb/go32-nat.c:387:1: error: conflicting types for 'go32_detach'
 ../../src/gdb/go32-nat.c:240:13: note: previous declaration of 'go32_detach' was here

go32_detach is actually defined before it's ever used, making the
forward declaration is unnecessary.  So we can just remove it instead
of updating it.  While at it, remove all others in the same situation.

psymtab cleanup patch 3/3

This last patch removes "partial" from the names of
expand_partial_symbol_names and map_partial_symbol_filenames.
It also renames expand_partial_symbol_names to match the
struct quick_symbol_functions "method" that it wraps:
expand_symtabs_matching.

This patch also adds two parameters to expand_symtabs_matching
so that it can fully wrap the underlying quick_symbol_functions method.
This makes it usable in more places.
I thought of having a cover function that still had the same
signature as the old expand_partial_symbol_names function,
but I couldn't think of a good name, and it wasn't clear it was
worth it anyway.

* symfile.h (expand_symtabs_matching): Renamed from
expand_partial_symbol_names.  Update prototype.
(map_symbol_filenames): Renamed from map_partial_symbol_filenames.
* symfile.c (expand_symtabs_matching): Renamed from

psymtab cleanup patch 2/3

This patch adds two typedefs:
expand_symtabs_file_matcher_ftype
expand_symtabs_symbol_matcher_ftype

It also renames the NAME_MATCHER argument in expand_symtabs_matching.
The function is named expand_symtabs_matching and it takes a name_matcher
argument.  Name of what?  The symtab?  A symbol?
I made it SYMBOL_MATCHER to make it clearer.

psymtab cleanup patch 1/3

This is the first of a set of three patches to cleanup psymtab.c a bit.

Basically, these two functions do not belong in psymtab.c:
expand_partial_symbol_names, map_partial_symbol_filenames,
and "partial" does not belong in the function name.

This first patch moves them to a better location.
The second patch adds some typedefs for function parameters to
quick_symbol_functions.expand_symtabs_matching.
The third patch removes "partial" from the function names
and uses them in more places.

* psymtab.c (expand_partial_symbol_names): Delete, moved to symfile.c.
(map_partial_symbol_filenames): Ditto.
* psymtab.h (expand_partial_symbol_names): Delete, moved to symfile.h.

Fix "is a record target open" checks.

RECORD_IS_USED and record_full_open look at current_target.to_stratum
to determine whether a record target is in use.  This is wrong because
arch_stratum is greater than record_stratum, so if an arch_stratum
target is pushed, RECORD_IS_USED and record_full_open will miss it.

To fix this, we can use the existing find_record_target instead, which
looks up for a record stratum target across the target stack.  Since
that means exporting find_record_target in record.h, RECORD_IS_USED
ends up redundant, so the patch eliminates it.

That exercise then reveals other issues:

- adjust_pc_after_break is gating record_full_... calls based on
RECORD_IS_USED.  But, record_full_ calls shouldn't be made when
recording with the record-btrace target.  So this adds a new
record_full_is_used predicate to be used in that spot.

- record_full_open says "Process record target already running", even
if the recording target is record-btrace ("process record" is the
original complete name of the record-full target).  record_btrace_open
only says "The process is already being recorded." and does not
suggest "record stop", like record-full does.  The patch factors out
and merges that error to a new record_preopen function that all record
targets call in their open routine.

Tested on x86_64 Fedora 17.

Have regdat.sh always rewrite the output register file

The rules for generating the output register files look like:

amd64.c : $(srcdir)/../regformats/i386/amd64.dat $(regdat_sh)
$(SHELL) $(regdat_sh) $(srcdir)/../regformats/i386/amd64.dat amd64.c

According to this rule, if regdat.sh is newer than amd64.c, then
regdat.sh shall be invoked on amd64.dat.  According to regdat.sh, if the
script determines that the output file amd64.c has not changed, then it
will not overwrite the existing output file.  This means that a
subsequent invocation of make will trigger the above rule again as
regdat.sh will be perpetually newer than amd64.c.

This then shows up in the make output like so:

/bin/bash ./../regformats/regdat.sh ./../regformats/i386/amd64-linux.dat amd64-linux.c
amd64-linux.c unchanged.
/bin/bash ./../regformats/regdat.sh ./../regformats/i386/amd64-avx-linux.dat amd64-avx-linux.c
amd64-avx-linux.c unchanged.
...

To fix this pathological behavior, it suffices to have regdat.sh
unconditionally rewrite the output register file.

On my machine, which has a regdat.sh file that is newer than some of the
input register files, this change speeds up every invocation of make
under gdb/ by about 5 seconds.

New "make check-headers" rule.

Do:

  make check-headers CHECK_HEADERS="header.h list.h"

to check specific headers.
