2020-06-17 Gary Dismukes <dismukes@adacore.com>
gcc/ada/
* aspects.ads (type Aspect_Id): Add Aspect_Static as a Boolean
aspect, and update the Is_Representation_Aspect, Aspect_Names,
and Aspect_Delay arrays.
* exp_ch6.adb (Expand_Simple_Function_Return): In the case of a
return for a static expression function, capture a copy of the
expression of the return statement before it's expanded and
reset its Analyzed flags. Then, just before leaving this
procedure, if the expression was rewritten, set the
Original_Node of the rewritten expression to the new copy and
also set the Expression of the associated static expression
function to designate that copy. This ensures that later copies
of the expression made via New_Copy_Tree will fully copy all
nodes of the expression tree.
* inline.ads (Inline_Static_Expression_Function_Call): New
procedure to evaluate and produce the result of a static call to
a static expression function.
* inline.adb: Add with and use for Sem_Res.
(Establish_Actual_Mapping_For_Inlined_Call): New procedure
extracted from code in Expand_Inlined_Call that traverses the
actuals and formals of an inlined call and in some cases creates
temporaries for holding the actuals, plus establishes an
association between formals and actuals (via the Renamed_Object
fields of the formals).
(Formal_Is_Used_Once): Function removed from Expand_Inlined_Call
and now nested in the above procedure.
(Expand_Inlined_Call): Code for doing the formal/actual
traversal is moved to Create_Actual_Temporaries and replaced
with a call to that new procedure.
(Inline_Static_Expression_Function_Call): New procedure to
evaluate a static call to a static expression function,
substituting actuals for their corresponding formals and
producing a fully folded and static result expression. The
function has subsidiary functions Replace_Formal and Reset_Sloc
that take care of doing the mapping of formals to actuals and
resetting the Slocs of subnodes of the mapped expression to that
of the call so errors will be flagged on the call rather than
function.
* sem_ch6.adb (Analyze_Expression_Function): In the case of a
static expression function, perform an additional preanalysis of
the function's expression to ensure that it's a potentially
static expression (according to the requirements of
6.8(3.2/5-3.4/5)), and issue an error if it's not. The global
flag Checking_Potentially_Static_Expression is set and unset
around this checking.
* sem_ch13.adb (Analyze_Aspect_Static): New procedure to enforce
selected requirements of the new aspect Static on expression
functions, including checking that the language version is
Ada_2020 and that the entity to which it applies is an
expression function whose formal parameters are of a static
subtype and have mode 'in', its result subtype is a static
subtype, and it has no pre- or postcondition aspects. A ???
comment is added to indicate the need for adding checking that
type invariants don't apply to the result type if the function
is a boundary entity.
(Analyze_One_Aspect): Call Analyze_Aspect_Static for aspect
Static.
* sem_elab.adb (Build_Call_Marker): Return without creating a
call marker when the subprogram is a static expression function,
since no ABE checking is needed for such functions.
* sem_eval.ads (Checking_Potentially_Static_Expression): New
function to return whether the checking for potentially static
expressions is enabled.
(Set_Checking_Potentially_Static_Expression): New procedure to
enable or disable checking of potentially static expressions.
* sem_eval.adb (Checking_For_Potentially_Static_Expression): New
global flag for determining whether preanalysis of potentially
static expression is being done, which affects the behavior of
certain static evaluation routines.
(Checking_Potentially_Static_Expression): New function to return
whether the checking for potentially static expressions is
enabled.
(Eval_Call): When evaluating a call within a static expression
function with checking of potentially static expression
functions enabled, substitutes a static value in place of the
call to allow folding of the expression.
(Eval_Entity_Name): When evaluating a formal parameter of a
static expression function with checking of potentially static
expression functions enabled, substitutes a static value in
place of the reference to the formal to allow folding of the
expression.
(Set_Checking_Potentially_Static_Expression): New procedure to
enable or disable checking of potentially static expressions.
* sem_res.adb (Resolve_Call): Test for a recursive call
occurring within a static expression function and issue an error
for such a call. Prevent the establishment of a transient scope
in the case this is a call to a (string-returning) static
expression function. When calling a static expression function,
if no error has been posted on the function, call
Inline_Static_Expression_Function_Call to convert the call into
its equivalent static value.
* sem_util.ads (Is_Static_Expression_Function): New function
returning whether the subprogram entity passed to it is a static
expression function.
(Is_Static_Expression_Function_Call): New function to determine
whether the call node passed to it is a static call to a static
expression function.
* sem_util.adb (Compile_Time_Constraint_Error): Suppress
compile-time Constraint_Error reporting when checking for a
potentially static expression.
(Is_Static_Expression_Function): New function returning whether
the subprogram entity passed to it is a static expression
function by testing for the presence of aspect Static.
(Has_All_Static_Actuals): New function in
Is_Static_Expression_Function_Call that traverses the actual
parameters of a function call and returns True only when all of
the actuals are given by static expressions. In the case of a
string-returning function, we call Resolve on each actual to
ensure that their Is_Static_Expression flag properly reflects
whether they're static, to allow suppressing creation of a
transient scope within Resolve_Call. A prominent ??? comment is
added to explain this rather unconventional call to Resolve.
(Is_Static_Expression_Function_Call): New function that
determines whether a node passed to it is a call to a static
expression function all of whose actual parameters are given by
static expressions.

[PATCH][GCC] arm: Fix MVE scalar shift intrinsics code-gen.
This patch modifies the MVE scalar shift RTL patterns. The current patterns
have wrong constraints and predicates due to which the values returned from
MVE scalar shift instructions are overwritten in the code-gen.
example:
$ cat x.c
int32_t foo(int64_t acc, int shift)
{
return sqrshrl_sat48 (acc, shift);
}
Code-gen before applying this patch:
$ arm-none-eabi-gcc -march=armv8.1-m.main+mve -mfloat-abi=hard -O2 -S
$ cat x.s
foo:
push {r4, r5}
sqrshrl r0, r1, #48, r2 ----> (a)
mov r0, r4 ----> (b)
pop {r4, r5}
bx lr
Code-gen after applying this patch:
foo:
sqrshrl r0, r1, #48, r2
bx lr
In the current compiler the return value (r0) from sqrshrl (a) is getting
overwritten by the mov statement (b).
This patch fixes above issue.

openmp: Initial part of OpenMP 5.0 non-rectangular loop support
OpenMP 5.0 adds support for non-rectangular loop collapses, e.g.
triangular and more complex.
This patch deals just with the diagnostics so that they aren't rejected
immediately as before. As the spec generally requires as before that the
iteration variable initializer and bound in the comparison as invariant
vs. the outermost loop, and just add some exceptional forms that can violate
that, we need to avoid folding the expressions until we can detect them and
in order to avoid folding it later on, I chose to use a TREE_VEC in those
expressions to hold the var_outer * expr1 + expr2 triplet, the patch adds
pretty-printing of that, gimplification etc. and just sorry_at during

c++: Improve access checking inside templates [PR41437]
This patch generalizes our existing functionality for deferring access
checking of typedefs when parsing a function or class template to now
defer all kinds of access checks until template instantiation time,
including member function and member object accesses.
Since all access checks eventually go through enforce_access, the main
component of this patch is new handling inside enforce_access to defer
the current access check if we're inside a template. The bulk of the
rest of the patch consists of removing now-unneeded code pertaining to
suppressing access checks inside templates or pertaining to
typedef-specific access handling. Renamings and other changes with no

Optimize assignment to volatile aggregate variable
gimplify_modify_expr_rhs has an optimization whereby the assignment to
an aggregate variable from a read-only object with a DECL_INITIAL is
optimized into the direct assignment of the DECL_INITIAL, provided that
no temporary is created in the process.
The optimization is blocked if the read-only object is volatile, which
is OK as per the semantics of volatile, but also if the target variable
is volatile, on the grounds that the modified assignment might end up
being done on a per field basis, which is also OK. But this latter
restriction is enforced a priori and there are cases where the modified
assignment would be OK, for example if there is only one field or the
DECL_INITIAL is equivalent to the empty CONSTRUCTOR, i.e. all zeros.
So, in the latter case, the patch changes gimplify_modify_expr_rhs to ask
gimplify_init_constructor whether the assignment would be done as a block,
which is easy because gimplify_init_constructor knows that it must create
a temporary if the LHS is volatile and this would not be the case, so it's
just a matter of completing the NOTIFY_TEMP_CREATION mechanism.
gcc/ChangeLog
* gimplify.c (gimplify_init_constructor) <AGGREGATE_TYPE>: Declare
new ENSURE_SINGLE_ACCESS constant and move variables down. If it is
true and all elements are zero, then always clear. Return GS_ERROR
if a temporary would be created for it and NOTIFY_TEMP_CREATION set.
(gimplify_modify_expr_rhs) <VAR_DECL>: If the target is volatile but
the type is aggregate non-addressable, ask gimplify_init_constructor
whether it can generate a single access to the target.

* gnat.dg/aggr30.ads, gnat.dg/aggr30.adb: New test.

Fix ICE in verify_sra_access_forest
This fixes an issue with reverse storage order in SRA, which is caught
by the built-in verifier in verify_sra_access_forest. The problem is
that propagate_subaccesses_from_rhs changes the type of an access
from aggregate to scalar and, as discussed elsewhere, this must be
done with extra care in the presence of reverse storage order.
gcc/ChangeLog
* tree-sra.c (propagate_subaccesses_from_rhs): When a non-scalar
access on the LHS is replaced with a scalar access, propagate the
TYPE_REVERSE_STORAGE_ORDER flag of the type of the original access.

libstdc++: Update value of __cpp_lib_constexpr_char_traits for C++20
Although not required by SD-6 or the C++20 draft, we define the macro
__cpp_lib_constexpr_char_traits to indicate support for P0432R1. This
updates the value in C++20 mode for the P1032R1 changes to char_traits.
* include/bits/char_traits.h (__cpp_lib_constexpr_char_traits):
Update value for C++20.

libstdc++: Fix char_traits move with overlap
Upon constexpr evaluation, char_traits move uses copy_backward, but its
last argument should be to the range end rather than its beginning.
2020-06-12 Paul Keir <paul.keir@uws.ac.uk>
* include/bits/char_traits.h (char_traits::move): constexpr move with
