* valops.c (do_search_struct_field): Pass v2 instead of base_type to

cleanup: make allocate_value_contents static

2013-08-29  Sanimir Agovic  <sanimir.agovic@intel.com>

* value.c (allocate_value_contents): Make static.
* value.h (allocate_value_contents): Remove prototype.

cleanup: use value_lazy_at instead of allocate_value_lazy/attribute setter

I came across a pattern used to construct a value in the following way:

  struct value *val = allocate_value_lazy (type);
  VALUE_LVAL (val) = lval_memory;
  set_value_address (val, address);

Instead we fold the above call into:

  value_at_lazy (type, addr);

Add options to skip unavailable locals

This is the patch to add new option '--skip-unavailable' to MI
commands '-stack-list-{locals, arguments, variables}'.  This patch
extends list_args_or_locals to add a new parameter 'skip_unavailable',
and don't list locals or arguments if values are unavailable and
'skip_unavailable' is true.

This is inspecting a trace frame (tfind mode), where only a few
locals have been collected.

-stack-list-locals, no switch vs new switch:

 -stack-list-locals --simple-values
 ^done,locals=[{name="array",type="unsigned char [2]"},{name="i",type="int",value="<unavailable>"}]
 -stack-list-locals --skip-unavailable --simple-values
 ^done,locals=[{name="array",type="unsigned char [2]"}]

-stack-list-arguments, no switch vs new switch:

 -stack-list-arguments --simple-values
 ^done,stack-args=[frame={level="0",args=[{name="j",type="int",value="4"},{name="s",type="char *",value="<unavailable>"}]},frame={level="1",args=[]}]
 -stack-list-arguments --skip-unavailable --simple-values
 ^done,stack-args=[frame={level="0",args=[{name="j",type="int",value="4"}]},frame={level="1",args=[]}]

-stack-list-variables, no switch vs new switch:

 -stack-list-variables --simple-values
 ^done,variables=[{name="j",arg="1",type="int",value="4"},{name="s",arg="1",type="char *",value="<unavailable>"},{name="array",type="unsigned char [2]"},{name="i",type="int",value="<unavailable>"}]
 -stack-list-variables --skip-unavailable --simple-values
 ^done,variables=[{name="j",arg="1",type="int",value="4"},{name="array",type="unsigned char [2]"}]

tests are added to test these new options.

Tested on x86-64 Fedora 18.

       * lib/cell.exp (skip_cell_tests): Use standard_temp_file.

introduce gdb_remote_download and finish parallel fixes in gdb.dwarf2

This finishes making gdb.dwarf2 parallel-safe.

To do this, this patch introduces a new gdb_remote_download proc, that
works somewhat differently in the one specific case where it matters:
for a copy to "host", if no destination was given, and the host is not
actually remote, then standard_output_file is used.  In parallel mode
this guarantees that the resulting file will end up in a parallel-safe
location.

Tested on x86-64 Fedora 18.

* gdb.dwarf2/dw2-basic.exp: Use gdb_remote_download.
* gdb.dwarf2/dw2-compressed.exp: Use gdb_remote_download.

fix some gdb.dwarf2 tests for parallel safety

This fixes a few gdb.dwarf2 tests to be more parallel-safe.  This
mostly amounts to changing them to write their files into the
directory designated by standard_output_file.

Built and regtested on x86-64 Fedora 18.

* gdb.dwarf2/dw2-minsym-in-cu.exp: Use standard_testfile.

dwarf2_evaluate_loc_desc_full (frame #7) knows to handle
NOT_AVAILABLE_ERROR errors, but read_memory always throws
a generic error.

Presently, only the value machinery knows to handle unavailable
memory.  We need to push the awareness down to the target_xfer layer,
making it return a finer grained error indication.  We can only return
a generic -1 nowadays, which leaves the upper layers with no clue on
why the xfer failed.  Use target_xfer_partial directly, rather than
propagating the error through target_read_memory so as to get a better
address to display in the error message.

(target_read_memory & friends build on top of target_read (thus the
target_xfer machinery), but turn all errors to EIO, an errno value.  I
think this is a mistake, and we'd better convert all these to return a
target_xfer_error too, but that can be done separately.  I looked
around a bit over memory_error calls, and the need to handle random
errno values, other than the EIOs gdb itself hardcodes, probably comes
(only) from deprecated_xfer_memory, which uses errno for error
indication, but I didn't look exhaustively.  We should really get rid
of deprecated_xfer_memory and of passing down errno values as error
indication in target_read & friends methods).

Tested on x86_64 Fedora 17, native and gdbserver.  Fixes the test in
the PR, which will be added to the testsuite later.

fix PR python/15816

This fixes PR python/15816.

The bug here is that python-selftest.exp can fail:

    No symbol "RETURN_MASK_ALL" in current context.

RETURN_MASK_ALL is a macro, so if macros do not end up in the
debuginfo (very typical) then the test fails.

It seemed simplest to me to simply turn the RETURN_MASK_ defines into
enum constants.  This way they end up in the debuginfo and all is
well.

PR python/15816:
* exceptions.h (return_mask): Now an enum.
(RETURN_MASK_QUIT, RETURN_MASK_ERROR, RETURN_MASK_ALL): Now
enum constants.

Built and regtested on x86-64 Fedora 18.

move gdbarch object from objfile to per-BFD

This moves the "gdbarch" field from the objfile into the BFD.

This field's value is derived from the BFD and is immutable over the
lifetime of the BFD.  This makes it a reasonable candidate for pushing
into the per-BFD object.

This is part of the long-term objfile splitting project.  In the long
run I think this patch will make it simpler to moves types from the
objfile to the per-BFD object; but the patch makes sense as a minor
cleanup by itself.
