[gimple-classes, committed 00/92] Initial slew of commits

[David Malcolm <dmalcolm at redhat dot com>]

These patches move the type-checking of gimple statement accessors
from run-time to compile-time, for about half of the accessors.

I've pushed them to the git branch "dmalcolm/gimple-classes", which
can be seen at:
https://gcc.gnu.org/git/?p=gcc.git;a=shortlog;h=refs/heads/dmalcolm/gimple-classes

Patches 01-87:
  These correspond to patches 02-89 from the patch kit I posted in
  April, and approved by Jeff (with various caveats), rebased against trunk,
  and eliminating the as_a_gimple_foo and dyn_cast_gimple_foo *methods* in
  favor of direct use of as_a <>/dyn_cast <> from is-a.h
  I used a script [1] to add references to the initial patch kit and Jeff's
  reviews to the commit messages.

  They introduce various new gimple subclasses, along with typedefs for the
  const/non-const variants.  Richi didn't want these typedefs, so I
  immediately undo this part, renaming them in followups... (doing it this
  way was the least error-prone way):

Patch 88: "Preparatory work before subclass renaming":
  Various variables have names that confuse my subclass renaming
  script.  Rename them now to simplify the mass-renaming.

Patches 89 and 90 only make sense together; the former is handwritten, the
latter autogenerated:
  Patch 89: "Eliminate subclass typedefs from coretypes.h"
    This patch eliminates the const/non-const typedefs for the gimple
    subclasses.
  Patch 90: "Automated renaming of gimple subclasses"
    This patch renames the gimple subclasses based on the pattern from
    https://gcc.gnu.org/ml/gcc-patches/2014-05/msg00346.html
    e.g.
      "gimple_switch" becomes "gswitch *".
      "const_gimple_bind" becomes "const gbind *".
  i.e. pointers to all gimple *subclasses* now must be explicitly referred
  to with "*".   "gimple" is still implicitly a pointer, to minimize noise
  when diffing against trunk.
  The renaming script was:
    https://github.com/davidmalcolm/gcc-refactoring-scripts/blob/master/rename_gimple_subclasses.py

Patch 91: "Remove out-of-date references to typedefs":
  Fix some now-bogus comments.

Patch 92: "Update gimple.texi class hierarchy diagram"

I've successfully bootstrapped and regrtested patches 01-90 on
x86_64-unknown-linux-gnu (Fedora 20) - same results relative to
an unpatched control bootstrap of the branchpoint (r216157).

For reference, here's what the class hierarchy diagram from
gimple.texi looks like after these patches, with the new subclass
names (e.g. "gassign" and "gphi"):
