C++-ify prologue-value's pv_area
This patch is an initial C++-ification of pv_area, from
prologue-value. It turns pv_area into a class with a constructor and
destructor; renames the data members; and changes various functions to
be member functions. This allows the removal of
make_cleanup_free_pv_area.

C++-ify prologue-value's pv_area
This patch is an initial C++-ification of pv_area, from
prologue-value. It turns pv_area into a class with a constructor and
destructor; renames the data members; and changes various functions to
be member functions. This allows the removal of
make_cleanup_free_pv_area.

C++-ify prologue-value's pv_area
This patch is an initial C++-ification of pv_area, from
prologue-value. It turns pv_area into a class with a constructor and
destructor; renames the data members; and changes various functions to
be member functions. This allows the removal of
make_cleanup_free_pv_area.

Replace some xmalloc-family functions with XNEW-family ones
This patch is part of the make-gdb-buildable-in-C++ effort. The idea is
to change some calls to the xmalloc family of functions to calls to the
equivalents in the XNEW family. This avoids adding an explicit cast, so
it keeps the code a bit more readable. Some of them also map relatively
well to a C++ equivalent (XNEW (struct foo) -> new foo), so it will be
possible to do scripted replacements if needed.
I only changed calls that were obviously allocating memory for one or
multiple "objects". Allocation of variable sizes (such as strings or
buffer handling) will be for later (and won't use XNEW).
- xmalloc (sizeof (struct foo)) -> XNEW (struct foo)
- xmalloc (num * sizeof (struct foo)) -> XNEWVEC (struct foo, num)
- xcalloc (1, sizeof (struct foo)) -> XCNEW (struct foo)
- xcalloc (num, sizeof (struct foo)) -> XCNEWVEC (struct foo, num)
- xrealloc (p, num * sizeof (struct foo) -> XRESIZEVEC (struct foo, p, num)
- obstack_alloc (ob, sizeof (struct foo)) -> XOBNEW (ob, struct foo)
- obstack_alloc (ob, num * sizeof (struct foo)) -> XOBNEWVEC (ob, struct foo, num)
- alloca (sizeof (struct foo)) -> XALLOCA (struct foo)
- alloca (num * sizeof (struct foo)) -> XALLOCAVEC (struct foo, num)
Some instances of xmalloc followed by memset to zero the buffer were
replaced by XCNEW or XCNEWVEC.
I regtested on x86-64, Ubuntu 14.04, but the patch touches many
architecture-specific files. For those I'll have to rely on the
buildbot or people complaining that I broke their gdb.

C++-ify prologue-value's pv_area
This patch is an initial C++-ification of pv_area, from
prologue-value. It turns pv_area into a class with a constructor and
destructor; renames the data members; and changes various functions to
be member functions. This allows the removal of
make_cleanup_free_pv_area.

C++-ify prologue-value's pv_area
This patch is an initial C++-ification of pv_area, from
prologue-value. It turns pv_area into a class with a constructor and
destructor; renames the data members; and changes various functions to
be member functions. This allows the removal of
make_cleanup_free_pv_area.
