Consider test.C compiled at -O0 -g:
...
class string {
public:
string (const char *p) { this->p = p ; }
string (const string &s) { this->p = s.p; }
private:
const char *p;
};
class foo {
public:
foo (string dir_hint) {}
};
int
main (void)
{
std::string s = "This is just a string";
foo bar(s);
return 0;
}
...
When parsing foo::foo, the dir_hint parameter gets a DECL_ARG_TYPE of
'struct string & restrict'. Then during finish_struct, we call
clone_constructors_and_destructors and create clones for foo::foo, and
set the DECL_ARG_TYPE in the same way.
Later on, during finish_function, cp_genericize is called for the original
foo::foo, which sets the type of parm dir_hint to DECL_ARG_TYPE, and sets
DECL_BY_REFERENCE of dir_hint to 1.
After that, during maybe_clone_body update_cloned_parm is called with:
...
(gdb) call debug_generic_expr (parm.typed.type)
struct string & restrict
(gdb) call debug_generic_expr (cloned_parm.typed.type)
struct string
...
The type of the cloned_parm is then set to the type of parm, but
DECL_BY_REFERENCE is not set.
When doing cp_genericize for the clone later on,
TREE_ADDRESSABLE (TREE_TYPE ()) is no longer true for the updated type for
the parm, so DECL_BY_REFERENCE is not set there either.
The missing DECL_BY_REFERENCE on cloned_parm causes incorrect debug info to be
generated.
This patch fixes the problem by copying DECL_BY_REFERENCE in update_cloned_parm.
Bootstrapped and reg-tested on x86_64.

Unlike the old vinfo_for_stmt, vec_info::lookup_stmt can cope with
any statement, so there's no need to check beforehand that the statement
is part of the vectorisable region. This means that there are no longer
any calls to vect_stmt_in_region_p.

There are no more direct uses of:
- new_stmt_vec_info
- set_vinfo_for_stmt
- free_stmt_vec_infos
- free_stmt_vec_info
outside of vec_info, so they can now be private member functions.
It also seemed better to put them in tree-vectorizer.c, along with the
other vec_info routines.
We can also get rid of:
- vinfo_for_stmt
- stmt_vec_info_vec
- set_stmt_vec_info_vec
since nothing now uses them. This was the main goal of the series.

This patch makes free_stmt_vec_info take the stmt_vec_info that
it's supposed to free and makes it free only that stmt_vec_info.
Callers need to update the statement mapping where necessary
(but now there are only a couple of callers).
This in turns means that we can leave ~vec_info to do the actual
freeing, since there's no longer a need to do it before resetting
the gimple_uids.

are really dealing with the way that an access is going to vectorised,

data_reference.

This patch makes dr_aux link back to both the scalar data_reference
and the containing stmt_vec_info, so that it becomes a suitable key
for a vectorisable reference.
The data_reference link is just STMT_VINFO_DATA_REF, moved here
from _stmt_vec_info. The stmt pointer is a new field and always
tracks the current stmt_vec_info for the reference (which might
be a pattern stmt or the original stmt).
The patch also makes the dr_aux in this current stmt be the one
that counts, rather than have the information stay with the DR_STMT.
A new macro (STMT_VINFO_DR_INFO) gives this information for a given
stmt_info.
In future we could make dr_aux a separate structure, which would
be useful if we want to support multiple data references per stmt.
That seems too much of a diversion for this series though.

This patch makes vect_dr_stmt return a stmt_vec_info instead of a
gimple stmt. Rather than retain a separate gimple stmt variable
in cases where both existed, the patch replaces uses of the gimple
variable with the uses of the stmt_vec_info. Later patches do this
more generally.
Many things that are keyed off a data_reference would these days
be better keyed off a stmt_vec_info, but it's more convenient
to do that later in the series. The vect_dr_size calls that are
left over do still benefit from this patch.

This patch makes vect_finish_replace_stmt and vect_finish_stmt_generation
return the stmt_vec_info for the vectorised statement, so that the caller
doesn't need a separate vinfo_for_stmt to get at it.
This involved changing the structure of the statement-generating loops
so that they use narrow scopes for the vectorised gimple statements
and use the existing (wider) scopes for the associated stmt_vec_infos.
This helps with gimple stmt->stmt_vec_info changes further down the line.
The way we do this generation is another area ripe for clean-up,
but that's too much of a rabbit-hole for this series.

This patch turns stmt_vec_info into an unspeakably bad wrapper class
and adds an implicit conversion to the associated gimple stmt.
Having this conversion makes the rest of the series easier to write,
but since the class goes away again at the end of the series, I've
not bothered adding any comments or tried to make it pretty.

This patch adds a vec_info replacement for vinfo_for_stmt. The main
difference is that the new routine can cope with arbitrary statements,
so there's no need to call vect_stmt_in_region_p first.
The patch only converts calls that are still needed at the end of the
series. Later patches get rid of most other calls to vinfo_for_stmt.

This patch adds a vec_info function for allocating and setting

The usual vectoriser dance to create new assignments is:
new_stmt = gimple_build_assign (vec_dest, ...);
new_temp = make_ssa_name (vec_dest, new_stmt);
gimple_assign_set_lhs (new_stmt, new_temp);
but one site in vectorizable_reduction used:
new_temp = make_ssa_name (vec_dest, new_stmt);
before creating new_stmt.
This method of creating statements probably needs cleaning up, but
that's for another day...

vect_is_slp_reduction and vect_is_simple_reduction had two instances

vect_free_slp_tree had:
gimple *stmt;
FOR_EACH_VEC_ELT (SLP_TREE_SCALAR_STMTS (node), i, stmt)
/* After transform some stmts are removed and thus their vinfo is gone. */
if (vinfo_for_stmt (stmt))
{
gcc_assert (STMT_VINFO_NUM_SLP_USES (vinfo_for_stmt (stmt)) > 0);
STMT_VINFO_NUM_SLP_USES (vinfo_for_stmt (stmt))--;
}
But after transform this update is redundant even for statements that do
exist, so it seems better to skip this loop for the final teardown.

vectorizable_reduction has old code to cope with cases in which the
given statement belongs to a reduction group but isn't the first statement.
That can no longer happen, since all statements in the group go into the
same SLP node, and we only check the first statement in each node.
The point is to remove the only path through vectorizable_reduction
in which stmt and stmt_info refer to different statements.
