My previous attempt at fixing this was incorrect. The problem occurs
earlier in that _cpp_lex_direct processes the unwinding EOF needs in
collect_args mode. This patch changes it not to do that, in the same
way as directive parsing works. Also collect_args shouldn't push_back
such fake EOFs, and neither should funlike_invocation_p.

* lex.c (_cpp_lex_direct): Do not complete EOF processing when
parsing_args.
* macro.c (collect_args): Do not unwind fake EOF.
(funlike_invocation_p): Do not unwind fake EOF.

copy_legacy_range was a small but complex function. It was tricky
to understand, and easy to introduce bugs into it. It also did
unnecessary work on some code paths.
This patch splits the function into two functions that are more
efficient and easier to read (copy_to_legacy and
copy_legacy_to_multi_range).
gcc/ChangeLog:
* value-range.cc (irange::operator=): Split up call to
copy_legacy_range into...
(irange::copy_to_legacy): ...this.
(irange::copy_legacy_to_multi_range): ...and this.
(irange::copy_legacy_range): Remove.
* value-range.h: Remove copoy_legacy_range.
Add copy_legacy_to_multi_range and copy_to_legacy.

Previously I've changed gimple_split_edge to avoid PHI node
re-allocation, but this introduced swapping of PHI arguments
due to the way edge redirection works. This is now a problem
for me and which can be solved with the following approach
reducing the overhead of split_edge even more. We can simply
pretend there are no PHI nodes if we can make sure the
new fallthru will have the same dest_idx as the old edge
into the destination.
2020-10-20 Richard Biener <rguenther@suse.de>
* tree-cfg.c (reinstall_phi_args): Remove.
(gimple_split_edge): Remove PHIs around the edge redirection
to avoid touching them at all.

We were using the wrong loop to figure the latch arg of a
double-reduction PHI. Which isn't a problem in case ->dest_idx
match up with the outer loop edges - but that's of course not guaranteed.

* tree-vect-loop.c (vectorizable_reduction): Use the correct

gcc/ada/
* sem_util.ads: Declare a new package, Old_Attr_Util, which in
turn declares two more packages, Conditional_Evaluation and
Indirect_Temps. Conditional_Evaluation provides a predicate for
deciding whether a given 'Old attribute reference is eligible
for conditional evaluation and, in the case where it is
eligible, a function that constructs the Boolean-valued
condition that is to be evaluated at run time in deciding
whether to evaluate the attribute prefix. Indirect_Temps
provides support for declaring a temporary which is only
initialized conditionally; more specifically, an access type and
a variable of that type are declared (unconditionally) and then
the variable is (conditionally) initialized with an allocator.
The existence of the access type and the pointer variable is
hidden from clients, except that a predicate,
Is_Access_Type_For_Indirect_Temp, is provided for identifying
such access types. This is needed because we want such an access
type to be treated like a "normal" access type (specifically
with respect to finalization of allocated objects). Other parts
of the compiler treat access types differently if
Comes_From_Source is False, or if the secondary stack storage
pool is used; this predicate is used to disable this special
treatment.
* sem_attr.adb (Uneval_Old_Msg): Improve message text to reflect
Ada202x changes.
(Analyze_Attribute): A previously-illegal 'Old attribute
reference is accepted in Ada2020 if it is eligible for
conditional evaluation.
* sem_res.adb (Valid_Conversion): Do not treat a rewritten 'Old
attribute like other rewrite substitutions. This makes a
difference, for example, in the case where we are generating the
expansion of a membership test of the form "Saooaaat'Old in
Named_Access_Type"; in this case Valid_Conversion needs to
return True (otherwise the expansion will be False - see the
call site in exp_ch4.adb).
* exp_attr.adb (Expand_N_Attribute_Reference): When expanding a
'Old attribute reference, test for the case where the reference
is eligible for conditional evaluation. In that case, use the
new "indirect temporary" mechanism provided by Sem_Util.
* exp_prag.adb
(Expand_Attributes_In_Consequence.Expand_Attributes): If
Sem_Util.Indirect_Temp_Needed indicates that there could be
correctness problems associated with the old expansion scheme
for dealing with 'Old attributes in contract cases consequences,
then we use the new "indirect temporary" mechanism provided by
Sem_Util instead. We do not want to do this unconditionally.
* sem_util.adb: Provide a body for the new Old_Attr_Util
package. Further work is needed in several areas for
correctness:
- The function Is_Repeatedly_Evaluated does not deal with
container aggregates yet.
- The function Is_Known_On_Entry does not deal with interactions
with the Global aspect.
Each area where more work is needed is indicated with a "???"
comment in the code; a more detailed description can be found
there. Some optimization opportunties are similarly indicated
with a "???" comment.
* exp_ch3.adb (Freeze_Type): In deciding whether to generate
expansion for the list controller of an access type, take the
predicate Is_Access_Type_For_Indirect_Temp into account. If the
predicate yields True, then generate the expansion.
* exp_util.adb (Build_Allocate_Deallocate_Proc): We don't
normally finalize allocated objects that are allocated on the
secondary stack. Add an exception to this rule if the predicate
Is_Access_Type_For_Indirect_Temp yields True. As a result of
this exception, we have to deal with the fact that gigi expects
a different parameter profile if we are using the secondary
stack pool; the Pool and Alignment parameters must be omitted in
this case.

* atree.adb (Extend_Node, New_Copy, New_Entity, New_Node):
Streamline these. Simplify and improve efficiency. Move code
from Allocate_Initialize_Node to these, where it can be executed
unconditionally. Take advantage of automatic zeroing of the
Nodes table.
(Allocate_Initialize_Node): Remove this. It was an efficiency
bottleneck, and somewhat complicated, because it was called from
4 places, and had all sorts of conditionals to check where it
was called from. Better to move most of that code to the call
sites, where it can be executed (or not) unconditionally.

At one stage, use cases were proposed for allowing the promise
type to contain both return_value and return_void. That was
not accepted into C++20, so we should reject it as per the PR.
gcc/cp/ChangeLog:
PR c++/97438
* coroutines.cc (struct coroutine_info): Add a field to
record that we emitted a promise type error.
(coro_promise_type_found_p): Check for the case that the
promise type contains both return_void and return_value.
Emit an error if so, with information about the wrong
type methods.
gcc/testsuite/ChangeLog:
PR c++/97438
* g++.dg/coroutines/pr97438.C: New test.

In PR 97456, IPA-SRA triggers a bug in tree-complex.c where it
converts:
<bb 2>
a$_M_value_21 = COMPLEX_EXPR <ISRA.18_10(D), ISRA.18_10(D)>;
(where ISRA.18 is IPA-SRA created PARM_DECL with DECL_IGNORED_P set,
which is why it only happens with IPA-SRA) into:
<bb 2>
a$_M_value_21 = COMPLEX_EXPR <a$_M_value$real_10(D), a$_M_value$real_10(D)>;
i.e. it replaces two uses of the parameter default-def with two
uninitialized default-defs of a new variable - all in hope to produce
code with better debug info.
This patch fixes it by avoiding the transform when the SSA_NAME to be
replaced is a default definition.

We inject EOF tokens between macro argument lists, but had
confused/stale logic in the non-fn invocation. Renamed the magic
'eof' token, as it's now only used for macro argument termination.
Always rewind the non-OPEN_PAREN token.
libcpp/
* internal.h (struct cpp_reader): Rename 'eof' field to 'endarg'.
* init.c (cpp_create_reader): Adjust.
* macro.c (collect_args): Use endarg for separator. Always rewind
in the not-fn case.
gcc/testsuite/
* c-c++-common/cpp/pr97471.c: New.

xvcvhpsp instruction converts a vector of bfloat16 half precision to single
precision. The intrinsics vextract_fp_from_shorth and
vextract_fp_from_shortl select the high or low four elements of a
half precision vector to convert. The intrinsics use vperm to select
the appropriate portion of the half precision vector and redistribute
the values for the xvcvhpsp instruction. The big endian versions of the
masks for the intrinsics were initialized wrong. This patch replaces the
masks with the correct values. This corrects the failure of
builtins-3-p9-runnable.c testcase on big endian systems.
Bootstrapped powerpc-ibm-aix7.2.3.0 Power9.
gcc/ChangeLog:
* config/rs6000/vsx.md (vextract_fp_from_shorth): Fix vals_be.
(vextract_fp_from_shortl) Same.
