PR target/55160
* gcc.target/sh/pr55160.c: New.

From-SVN: r193071

This patch renames sbitmap iterators to unify them with the bitmap iterators.

Remove the unused EXECUTE_IF_SET_IN_SBITMAP_REV, which has an unconventional
interface.

Rename the sbitmap_iter_* functions to match bitmap's bmp_iter_* functions.
Add an additional parameter to the initialization and next functions to
match the interface in bmp_iter_*.  This extra parameter is mostly hidden
by the use of the EXECUTE_IF macros.

Rename the EXECUTE_IF_SET_IN_SBITMAP macro to EXECUTE_IF_SET_IN_BITMAP.  Its
implementation is now identical to that in bitmap.h.  To prevent redefinition
errors, both definitions are now guarded by #ifndef.  An alternate strategy
is to simply include bitmap.h from sbitmap.h.  As this would increase build
time, I have elected to use the #ifndef version.  I do not have a strong
preference here.

The sbitmap_iterator type is still distinctly named because it is often
declared in contexts where the bitmap type is not obvious.  There are less
than 40 uses of this type, so the burden to modify it when changing bitmap
types is not large.

Tested on x86-64, config-list.mk testing.

This patch implements generic type query and conversion functions,

and applies them to the use of cgraph_node, varpool_node, and symtab_node.

The functions are:

bool is_a <TYPE> (pointer)
  Tests whether the pointer actually points to a more derived TYPE.

TYPE *as_a <TYPE> (pointer)
  Converts pointer to a TYPE*.

TYPE *dyn_cast <TYPE> (pointer)
  Converts pointer to TYPE* if and only if "is_a <TYPE> pointer".
  Otherwise, returns NULL.
  This function is essentially a checked down cast.

These functions reduce compile time and increase type safety when treating a
generic item as a more specific item.  In essence, the code change is from

  if (symtab_function_p (node))
    {
      struct cgraph_node *cnode = cgraph (node);
      ....
    }

to

  if (cgraph_node *cnode = dyn_cast <cgraph_node> (node))
    {
      ....
    }

The necessary conditional test defines a variable that holds a known good
pointer to the specific item and avoids subsequent conversion calls and
the assertion checks that may come with them.

When, the property test is embedded within a larger condition, the variable
declaration gets pulled out of the condition.  (This leaves some room for
using the variable inappropriately.)

  if (symtab_variable_p (node)
      && varpool (node)->finalized)
    varpool_analyze_node (varpool (node));

becomes

  varpool_node *vnode = dyn_cast <varpool_node> (node);
  if (vnode && vnode->finalized)
    varpool_analyze_node (vnode);

Note that we have converted two sets of assertions in the calls to varpool
into safe and efficient use of a variable.

There are remaining calls to symtab_function_p and symtab_variable_p that
do not involve a pointer to a more specific type.  These have been converted
to calls to a functions is_a <cgraph_node> and is_a <varpool_node>.  The
original predicate functions have been removed.

The cgraph.h header defined both a struct and a function with the name
varpool_node.  This name overloading can cause some unintuitive error messages
when, as is common in C++, one omits the struct keyword when using the type.
I have renamed the function to varpool_node_for_decl.

Tested on x86_64.

PR c++/54955 - Fail to parse alignas expr at the beginning of a declaration

In this PR, g++ embarrassingly fails to parse the simple alignas
expression below:

    alignas(double) int f;

even though the simple-declaration production in Clause 7 suggests
otherwise.

Fixed thus and tested on x86_64-unknown-linux-gnu against trunk.

Daily bump.

From-SVN: r192975

This patch implements the unification of the *bitmap interfaces as discussed.

Essentially, we rename ebitmap and sbitmap functions to use the same names
as the bitmap functions.  This rename works because we can now overload
on the bitmap type.  Some macros now become inline functions to enable
that overloading.

The sbitmap non-bool returning bitwise operations have been merged with
the bool versions.  Sometimes this merge involved modifying the non-bool
version to compute the bool value, and sometimes modifying bool version to
add additional work from the non-bool version.  The redundant routines have
been removed.

The allocation functions have not been renamed, because we often do not
have an argument on which to overload.  The cardinality functions have not
been renamed, because they have different parameters, and are thus not
interchangable.  The iteration functions have not been renamed, because
they are functionally different.

Tested on x86_64, contrib/config-list.mk testing passed.
