I've tried to build stage3 with
-Wleading-whitespace=blanks -Wtrailing-whitespace=blank -Wno-error=leading-whitespace=blanks -Wno-error=trailing-whitespace=blank
added to STRICT_WARN and that expectably resulted in about
2744 unique trailing whitespace warnings and 124837 leading whitespace
warnings when excluding *.md files (which obviously is in big part a
generator issue). Others from that are generator related, I think those
need to be solved later.
The following patch just fixes up the easy case (trailing whitespace),
which could be easily automated:
for i in `find . -name \*.h -o -name \*.cc -o -name \*.c | xargs grep -l '[ ]$' | grep -v testsuite/`; do sed -i -e 's/[ ]*$//' $i; done
I've excluded files which I knew are obviously generated or go FE.
Is there anything else we'd want to avoid the changes?
Due to patch size, I've split it between gcc/ part (this patch)
and rest (include/, libiberty/, libgcc/, libcpp/, libstdc++-v3/).

Currently we implement [temp.deduct.guide] p1 by forcing all deduction
guides to be considered as exported. However this is not sufficient:
for transitive non-exported imports we will still hide the deduction
guide from name lookup, causing errors.
This patch instead adjusts name lookup to have a new ANY_REACHABLE flag
to allow for this case. Currently this is only used by deduction guides
but there are some other circumstances where this may be useful in the
future (e.g. finding existing temploid friends).
PR c++/116403
gcc/cp/ChangeLog:
* pt.cc (deduction_guides_for): Use ANY_REACHABLE for lookup of

Currently name lookup generally seems to assume that all entities
declared within a named module (partition) are attached to said module,
which is not true for GM entities (e.g. via extern "C++"), and causes
issues with deduplication.
This patch fixes the issue by ensuring that module attachment of a
declaration is consistently used to handling merging. Handling this
exposes some issues with deduplicating temploid friends; to resolve this
we always create the BINDING_SLOT_PARTITION slot so that we have
somewhere to place attached names (from any module).
This doesn't yet completely handle issues with allowing otherwise
conflicting temploid friends from different modules to co-exist in the
same module if neither are reachable from the other via name lookup.

This patch fixes a couple issues with the current handling of revealing
declarations with using-decls.
Firstly, doing 'remove_node' when handling function overload sets is not
safe, because it not only mutates the OVERLOAD we're walking over but
potentially any other references to this OVERLOAD that are cached from
phase-1 template lookup. This causes the attached using-17 testcase to
fail because the overload set in 'X::test()' no longer contains the
'ns::f(T)' template once instantiated at the end of the file.
This patch works around this by simply not removing the old declaration.
This does make the overload list potentially longer than it otherwise
would have been, but only when re-exporting the same set of functions in
a using-decl. Additionally, because 'ovl_insert' always prepends these
newly inserted overloads, repeated exported using-decls won't continue
to add declarations, as the first exported using-decl will be found
before the original (unexported) declaration.
Another, related, issue is that using-decls of GMF entities currently
doesn't mark them as reachable unless they are also exported, and thus
they may not be available in e.g. module implementation units. We solve
this with a new flag on OVERLOADs set when they are declared within the
module purview. This starts to run into the more general issue of
handling using-decls of non-functions (see e.g. PR114863) but by just
marking such GMF entities as purview we can work around this for now.
This also allows us to get rid of the special-casing of exported
using-decls in 'add_binding_entity', which was incorrect anyway: a
non-exported using-decl still needs to be emitted anyway if it lives in
the module purview, even if referring to a non-purview item.

The lists of scope kinds used by ENABLE_SCOPE_CHECKING don't seem to
have been updated in a long while, causing ICEs and confusing output.
This patch brings the list into line.

only valid if kind is 'sk_template_parms', so we rewrite the condition
to be more obviously correct here.

function-try-block [PR52953]
As the following testcase shows, while check_local_shadow diagnoses most of
the [basic.scope.block]/2 violations, it doesn't diagnose when parameter's
name is redeclared inside of the compound-stmt of a function-try-block.
There is in that case an extra scope (sk_try with parent artificial
sk_block with for FUNCTION_NEEDS_BODY_BLOCK another sk_block and only then
sk_function_param).
The in_function_try_handler case doesn't work correctly
void
foo (int x)
try {
}
catch (int)
{
try {
} catch (int x)
{
}
try {
} catch (int)
{
int x;
}
}
(which is valid) is rejected, because
|| (TREE_CODE (old) == PARM_DECL
&& (current_binding_level->kind == sk_catch
|| current_binding_level->level_chain->kind == sk_catch)
&& in_function_try_handler))
is true but nothing verified that for the first case
current_binding_level->level_chain->kind == sk_function_params
(with perhaps artificial scopes in between and in the latter case
with one extra level in between).
The patch also changes behavior where for catch handlers of function-try-block
the diagnostics will have the shadows function parameter wording as pedwarn
rather than the old redeclaration permerror.

Now that we support NRV from an inner block, we can also support non-NRV
returns from other blocks, since once the NRV is out of scope a later return
expression can't possibly alias it.
This fixes 58487 and half-fixes 53637: now one of the returns is elided, but
not the other.
Fixing the remaining xfails in these testcases will require a very different
approach, probably involving a full tree/block walk from finalize_nrv, and
check_return_expr only adding to a list of potential return variables.

Here it turns out I also needed to adjust cfun when stepping out of the
member function to instantiate the DMI. But instead of adding that tweak,
let's unify with instantiate_body and just push_to_top_level instead of
trying to do the minimum subset of it. There was no measurable change in
compile time on stdc++.h.
This should also resolve 109506 without yet another tweak.

This adds module attachment as a distinct flag to 'in module purview'.
A declaration may have neither or both (as before), but can also have
just the 'in [named-module] purview', which was previously not

builtins), which was a little warty. Some other internal APIs get

We were failing to declare class S in the global namespace because we were
treating the requires-expression parameter scope as a normal block scope, so
the implicit declaration went there.
It seems to me that the requires parameter scope is more like a function
parameter scope (not least in the use of the word "parameter"), so let's
change the scope kind. But then we need to adjust the prohibition on
placeholders declaring implicit template parameters.

In order to properly implement two-stage name lookup for dependent
operator expressions, we need to remember the result of unqualified
lookup of the operator at template definition time, and reuse that
result rather than performing another unqualified lookup at
instantiation time.
Ideally we could just store the lookup in the expression directly, but
as pointed out in r9-6405 this isn't really possible since we use the
standard tree codes to represent most dependent operator expressions.
We could perhaps create a new tree code to represent dependent operator
expressions, with enough operands to store the lookup along with
everything else, but that'd require a lot of careful work to make sure
we handle this new tree code properly across the frontend.
But currently type-dependent operator (and call) expressions are given
an empty TREE_TYPE, which dependent_type_p treats as dependent, so this
field is effectively unused except to signal that the expression is
type-dependent. It'd be convenient if we could store the lookup there
while preserving the dependent-ness of the expression.
To that end, this patch creates a new kind of type, called
DEPENDENT_OPERATOR_TYPE, which we give to dependent operator expressions
and into which we can store the result of operator lookup at template
definition time (DEPENDENT_OPERATOR_TYPE_SAVED_LOOKUPS). Since this
type is always dependent (by definition), and since the frontend doesn't
seem to care much about the exact type of a type-dependent expression,
using this type in place of a NULL_TREE type seems to "just work"; only
dependent_type_p and WILDCARD_TYPE_P need to be adjusted to return true
for this new type.
The rest of the patch mostly consists of adding the necessary plumbing
to pass DEPENDENT_OPERATOR_TYPE_SAVED_LOOKUPS to add_operator_candidates,
adjusting all callers of build_x_* appropriately, and removing the now
unnecessary push_operator_bindings mechanism.
In passing, this patch simplifies finish_constraint_binary_op to avoid
using build_x_binary_op for building a binary constraint-expr; we don't
need to consider operator overloads here, as the &&/|| inside a
constraint effectively always has the built-in meaning (since atomic
constraints must have bool type).
This patch also makes FOLD_EXPR_OP yield a tree_code instead of a raw
INTEGER_CST.
Finally, this patch adds the XFAILed test operator-8.C which is about
broken two-stage name lookup for rewritten non-dependent operator
expressions, an existing bug that's otherwise only documented in
build_new_op.

This patch addresses 99170. with modules (and in particular header
units), one module can provide a (maybe nested) class or template and
another module can provide a definition or (maybe partial)
specialization of said entity, or member thereof. when both are
imported into a 3rd TU, and that TU instantiates or uses the class, it
needs to stream in those entities (in general). But how does it key
those entities to the original? It can't /just/ use the entity index,
because, when header-units and/or partitions are in play, the entity
index /is not unique/. I had two complicated schemes that tried to
unify that, but it failed. Here's a simpler scheme. Such pending
entities are keyed to the namespace and identifier of the
namespace-scope entity that contains them. Thus the final TU needs to
find that entity and look in a hash table for lists of sections that
need loading just before instantiating a template or looking inside a
class.
I would like to make this more efficient, but given the complex scheme
failed, I'm shooting for correctness right now. There will be a
follow up patch to complete the cleanup this enables.

This reworks namespace serializing to avoid some issues I ran into
when working on 99170. In modules, (non-anonymous) namespaces are

With modules one can have using-decls refering to their own scope. This
is the way to export things from the GMF or from an import. The
problem was I was using current_ns == CP_DECL_CONTEXT (decl) to
determine whether a decl should be registered in a namespace level or
not. But that's an inadequate check and we ended up reregistering
decls and creating a circular list. We should be registering the decl
when first encountered -- whether we bind it is orthogonal to that.

IDENTIFIER_TYPE_VALUE and friends is a remnant of G++'s C origins. It
holds elaborated types on identifier-nodes. While this is fine for C
and for local and class-scopes in C++, it fails badly for namespaces.
In that case a marker 'global_type_node' was used, which essentially
signified 'this is a namespace-scope type *somewhere*', and you'd have
to do a regular name_lookup to find it. As the parser and
substitution machinery has avanced over the last 25 years or so,
there's not much outside of actual name-lookup that uses that.
Amusingly the IDENTIFIER_HAS_TYPE_VALUE predicate will do an actual
name-lookup and then users would repeat that lookup to find the
now-known to be there type.
Rather late I realized that this interferes with the lazy loading of
module entities, because we were setting IDENTIFIER_TYPE_VALUE to
global_type_node. But we could be inside some local scope where that
identifier is bound to some local type. Not good!
Rather than add more cruft to look at an identifier's shadow stack and
alter that as necessary, this takes the approach of removing the
existing cruft.
We nuke the few places outside of name lookup that use
IDENTIFIER_TYPE_VALUE. Replacing them with either proper name
lookups, alternative sequences, or in some cases asserting that they
(no longer) happen. Class template instantiation was calling pushtag
after setting IDENTIFIER_TYPE_VALUE in order to stop pushtag creating
an implicit typedef and pushing it, but to get the bookkeeping it
needed. Let's just do the bookkeeping directly.
Then we can stop having a 'bound at namespace-scope' marker at all,
which means lazy loading won't screw up local shadow stacks. Also, it
simplifies set_identifier_type_value_with_scope, as it never needs to
inspect the scope stack. When developing this patch, I discovered a
number of places we'd put an actual namespace-scope type on the
type_value slot, rather than global_type_node. You might notice this
is killing at least two 'why are we doing this?' comments.
While this doesn't fix the two PRs mentioned, it is a necessary step.

My recent patch that introduced push_using_decl_bindings didn't
handle USING_DECL redeclaration, therefore things broke. This patch
amends that by breaking out a part of finish_nonmember_using_decl
out to a separate function, push_using_decl_bindings, and calling it.
It needs an overload, because name_lookup is only available inside
of name-lookup.c.

In r11-4690 we removed the call to finish_nonmember_using_decl in
tsubst_expr/DECL_EXPR in the USING_DECL block. This was done not
to perform name lookup twice for a non-dependent using-decl, which
sounds sensible.
However, finish_nonmember_using_decl also pushes the decl's bindings
which we still have to do so that we can find the USING_DECL's name
later. In this case, we've got a USING_DECL N::operator<< that we are
tsubstituting. We already looked it up while parsing the template
"foo", and lookup_using_decl stashed the OVERLOAD it found into
USING_DECL_DECLS. Now we just have to update the IDENTIFIER_BINDING of
the identifier for operator<< with the overload the name is bound to.
I didn't want to export push_local_binding so I've introduced a new
wrapper.

This adds a set of calls to name lookup that are needed by modules.
Generally installing imported bindings, or walking the current TU's
bindings. One note about template instantiations though. When we're
about to instantiate a template we have to know about all the
maybe-partial specializations that exist. These can be in any
imported module -- not necesarily the module defining the template.
Thus we key such foreign templates to the innermost namespace and
identifier of the containing entitity -- that's the only thing we have
a handle on. That's why we note and load pending specializations here.

This augments the name lookup with knowledge about the BINDING_VECTOR.
That holds per-module namespace bindings, and we need to collect the
bindings in visible imports when we do lookup. We also need to do
some checking when we're pushing a new decl to check we're not
overriding an existing visible binding in some way.
To deal with the Global Module and Module Partitions, we reserve 1 or
2 slots inthe BINDING_VECTOR to record those entities that may
legitimately appear in more than one module.
As mentioned before, the BINDING_VECTOR is created lazily, when
imported bindings appear. The current TUs decls then appear on slot
zero.

This adds the vector necessary to hold different module's namespace
bindings. We add a new tree-node 'tree_binding_vec', which contains a
sparse array, indexed by module number. To avoid space wasting, this
is allocated in clusters using 'unsigned short' as the index value (so
that's one of the upper bounds on module importing). If there are
only bindings from the current TU, there is no vector, so we have the
same representation as a non-module compilation.
To support lazy loading, a binding slot can contain either a tree (the
binding), or a cookie that the module machinery uses to load the
required binding on demand.
The first 2 or 3 slots end up being reserved for fixed meanings.
There are a couple of flags we have to record on a binding, to know
whether the same declaration could appear in two different slots.

During the implementation of modules I added myself a note to
implement nested_udt handling. It wasn't obvious to me what they were
for and nothing seemed to be broken in ignoring them. I figured
something would eventually pop up and I'd add support. Nothing popped up.
Investigating on trunk discovered 3 places where we look at the
nested-udts. I couldn't figure how the one in lookup_field_r was
needed -- surely the regular lookup would find the type. It turned
out that code was unreachable. So we can delete it.
Next in do_type_instantiation, we walk the nested-utd table
instantiating types. But those types are also on the TYPE_FIELDS
list, which we've just iterated over. So I can move the handling into
that loop.
The final use is in handling structs that have a typedef name for
linkage purposes. Again, we can just iterate over TYPE_FIELDS. (As
commented, we probably don't need to do even that, as a DR, whose
number I forget, requires such structs to only have C-like things in
them. But I didn't go that far.
Having removed all the uses of nested-udts, I can remove their
creation from name-lookup, and as the only instance of a binding_table
object, we can remove all that code too.

This patch improves block-scope extern handling by always injecting a
hidden copy into the enclosing namespace (or using a match already
there). This hidden copy will be revealed if the user explicitly
declares it later. We can get from the DECL_LOCAL_DECL_P local extern
to the alias via DECL_LOCAL_DECL_ALIAS. This fixes several bugs and
removes the kludgy per-function extern_decl_map. We only do this
pushing for non-dependent local externs -- dependent ones will be
pushed during instantiation.
User code that expected to be able to handle incompatible local
externs in different block-scopes will no longer work. That code is
ill-formed. (always was, despite what 31775 claimed). I had to
adjust a number of testcases that fell into this.
I tried using DECL_VALUE_EXPR, but that didn't work out. Due to
constexpr requirements we have to do the replacement very late (it
happens in the gimplifier). Consider:
extern int l[]; // #1
constexpr bool foo ()
{
extern int l[3]; // this does not complete the type of decl #1
constexpr int *p = &l[2]; // ok
return !p;
}
This requirement, coupled with our use of the common folding machinery
makes pr97306 hard to fix, as we end up with an expression containing
the two different decls for 'l', and only the c++ FE knows how to
reconcile those. I punted on this.

This patch moves the handling of decl-hiddenness entirely into the
name lookup machinery, where it belongs. We need a few new flags,
because pressing the existing OVL_HIDDEN_P into play for non-function
decls doesn't work well. For a local binding we only need one marker,
as there cannot be both a hidden implicit typedef and a hidden
function. That's not true for namespace-scope, where they could both
be hidden.
The name-lookup machinery maintains the existing decl_hidden and co
flags, and asserts have been sprinkled around to make sure they are
consistent. The next series of patches will remove those old markers.
(we'll need to keep one, as there are some special restrictions on
redeclaring friend functions with in-class definitions or default args.)

The decl pushing APIs and duplicate_decls take an 'is_friend' parm,
when what they actually mean is 'hide this from name lookup'. That
conflation has gotten more anachronistic as time moved on. We now
have anticipated builtins, and I plan to have injected extern decls
soon. So this patch is mainly a renaming excercise. is_friend ->
hiding. duplicate_decls gets an additional 'was_hidden' parm. As
I've already said, hiddenness is a property of the symbol table, not
the decl. Builtins are now pushed requesting hiding, and pushdecl
asserts that we don't attempt to push a thing that should be hidden
without asking for it to be hidden.
This is the final piece of groundwork to get rid of a bunch of 'this
is hidden' markers on decls and move the hiding management entirely
into name lookup.

In cleaning up local decl handling, here's an initial patch that takes
advantage of C++'s default args for the is_friend parm of pushdecl,
duplicate_decls and push_template_decl_real and the scope & tpl_header
parms of xref_tag. Then many of the calls simply not mention these.
I also rename push_template_decl_real to push_template_decl, deleting
the original forwarding function. This'll make my later patches
changing their types less intrusive. There are 2 functional changes:
1) push_template_decl requires is_friend to be correct, it doesn't go
checking for a friend function (an assert is added).

This patch deals with LOOKUP_HIDDEN, which originally meant 'find
hidden friends', but it's being pressed into service for not ignoring
lambda-relevant internals. However these two functions are different.
(a) hidden friends can occur in block scope (very uncommon) and (b) it
had the semantics of stopping after the innermost enclosing
namepspace. That's really suspect for the lambda case, but not
relevant there because we never get to namespace scope (I think).
Anyway, I've split the flag into two and adjusted the lambda callers
to just search block scope. These two flags are added to the
LOOK_want enum class, which allows dropping another parameter from the
name lookup routines.
The remaining LOOKUP_$FOO flags in cp-tree.h are, I think, now all
related to features of overload resolution, conversion operators and
reference binding. Nothing to do with /name/ lookup.

Continuing fixing name lookup's API we have two parameters saying what
we'd like to find 'prefer_type', which is a tri-valued boolan with
meaning 'don't care', 'type or namespace', 'type or death'. And we
have a second parameter 'namespaces_only', which means 'namespace or
death'. There are only 4 states, because the latter one has priority.
Firstly 'prefer_type' isn't really the right name -- it's not a preference,
it's a requirement. Name lookup maps those two parameters into 2 LOOKUP_
bits. We can simply have callers express that desire directly.
So this adds another enum class, LOOK_want, which expresses all
those options in 2 bits. Most of this patch is then the expected fallout
from such a change. The parser was mapping its internal state into
a prefer_type value, which was then mapped into the LOOKUP_ bits. So this
saves a conversion there. Also the parser's conversion routine had an
'is_template' flag, which was only ever true in one place, where the parser
also had to deal with other nuances of the flags to pass. So just drop
that parm and deal with it at the call site too.
I've left LOOKUP_HIDDEN alone for the moment. That'll be next.

The API for lookup_name_real is really confusing. This addresses the part
where we have NONCLASS to say DON'T search class scopes, and BLOCK_P to say
DO search block scopes. I've added a single bitmask to explicitly say which
scopes to search. I used an enum class so one can't accidentally misorder
it. It's also reordered so we don't mix it up with the parameters that say
what kind of thing we're looking for.

For named function calls in a template, the result of unqualified lookup is
safed in CALL_EXPR_FN. But for operator expressions, no unqualified lookup
is performed until we know whether the operands have class type. So when we
see in a lambda a use of an operator that might be overloaded, we need to do
that lookup then and save it away somewhere. One possibility would be in
the expression, but we can't really add extra conditional operands to
standard tree codes. I mostly implemented another approach using a new
WITH_LOOKUP_EXPR code, but teaching everywhere how to handle a new tree code
is always complicated. Then it occurred to me that we could associate the
lookups with the function, which is both simpler and smaller. So this patch
stores any operator bindings needed by a lambda function in an internal
attribute on the lambda call operator.
