* treepr.adb: Remove local To_Lower and use the procedure
version instead.
|

This fixes a crash on the declaration of a private derived enumeration type
with the Default_Initial_Condition aspect and in the process makes a couple
of related adjustments: 1) removes the early freezing of implicit character
and numeric base types and 2) fixes an oversight in the implementation of
delayed representation aspects.

Intersecting two ranges where one is a NAN is keeping the sign bit of
the NAN range. This is not correct as the sign bits may not match.
I think the only time we're absolutely sure about the intersection of
a NAN and something else, is when both are a NAN with exactly the same
properties (sign bit). If we're intersecting two NANs of differing
sign, we can decide later whether that's undefined or just a NAN with
no known sign. For now I've done the latter.
I'm still mentally working on intersections involving NANs, especially
if we want to keep track of signbits. For now, let's be extra careful
and only do things we're absolutely sure about.
Later we may want to fold the intersect of [NAN,NAN] and say [3,5]
with the posibility of NAN, to a NAN, but I'm not 100% sure. As I've
said before, setting varying is always a safe choice, because it means
we know nothing and ranger won't attempt to optimize anything.

When unioning a known NAN and something else, we're dropping the

It seems there are macros as well as functions for things like

The following patch implements part of the OpenMP 5.2 changes related
to ordered loops and with the assumed resolution of
https://github.com/OpenMP/spec/issues/3302 issues.
The changes are:
1) the depend clause on stand-alone ordered constructs has been renamed
to doacross (because depend clause has different syntax on other
constructs) with some syntax changes below, depend clause is deprecated
(we'll deprecate stuff on the GCC side only when we have everything else
from 5.2 implemented)
depend(source) -> doacross(source:) or doacross(source:omp_cur_iteration)
depend(sink:vec) -> doacross(sink:vec) (where vec has the same syntax
as before)
2) in 5.1 and before it has been significant whether ordered clause has or
doesn't have an argument, if it didn't, only block-associated ordered
could appear in the body, if it did, only stand-alone ordered could appear
in the body, all loops had to be perfectly nested, no associated
range-based for loops, no linear clause on work-sharing loop and ordered
clause with an argument wasn't allowed on composite for simd.
In 5.2, whether ordered clause has or doesn't have an argument is
insignificant (except for bugs in the standard, #3302 mentions those),
if the argument is missing, it is simply treated as equal to collapse
argument (if any, otherwise 1). The implementation better should be able
to differentiate between ordered and doacross loops at compile time
which previously was through the absence or presence of the argument,
now it is done through looking at the body of the construct lexically
and looking for stand-alone ordered constructs. If there are any,
it is to be handled as doacross loop, otherwise it is ordered loop
(but in that case ordered argument if present must be equal to collapse
argument - 5.2 says instead it must be one, but that is clearly wrong
and mentioned in #3302) - stand-alone ordered constructs must appear
lexically in the body (and had to before as well). For the restrictions
mentioned above, the for simd restriction is gone (stand-alone ordered
can't appear in simd construct, so that is enough), and the other rules
are expected to be changed into something related to presence of
stand-alone ordered constructs in the body
3) 5.2 allows a new syntax, doacross(sink:omp_cur_iteration-1), which
means wait for previous iteration in the iteration space of all the
associated loops
The following patch implements that, except that we sorry for now
on the doacross(sink:omp_cur_iteration-1) syntax during omp expansion
because library side isn't done yet for it. It doesn't implement it for
the Fortran FE either.
Incrementally, I'd like to change the way we differentiate between
stand-alone and block-associated ordered constructs, because the current
way of looking for presence of doacross clause doesn't work well if those
clauses are removed because they had been invalid (wrong syntax or
unknown variables in it etc.) and of course implement
doacross(sink:omp_cur_iteration-1).

PR c/90885 notes various places in real-world code where people have
written C/C++ code that uses ^ (exclusive or) where presumbably they
meant exponentiation.
For example
https://codesearch.isocpp.org/cgi-bin/cgi_ppsearch?q=2%5E32&search=Search
currently finds 11 places using "2^32", and all of them appear to be
places where the user means 2 to the power of 32, rather than 2
exclusive-orred with 32 (which is 34).
This patch adds a new -Wxor-used-as-pow warning to the C and C++
frontends to complain about ^ when the left-hand side is the decimal
constant 2 or the decimal constant 10.
This is the same name as the corresponding clang warning:
https://clang.llvm.org/docs/DiagnosticsReference.html#wxor-used-as-pow
As per the clang warning, the warning suggests converting the left-hand
side to a hexadecimal constant if you really mean xor, which suppresses
the warning (though this patch implements a fix-it hint for that, whereas
the clang implementation only has a fix-it hint for the initial
suggestion of exponentiation).
I initially tried implementing this without checking for decimals, but
this version had lots of false positives. Checking for decimals
requires extending the lexer to capture whether or not a CPP_NUMBER
token was decimal. I added a new DECIMAL_INT flag to cpplib.h for this.
Unfortunately, c_token and cp_tokens both have only an unsigned char for
their flags (as captured by c_lex_with_flags), whereas this would add
the 12th flag to cpp_tokens. Of the first 8 flags, all but BOL are used
in the C or C++ frontends, but BOL is not, so I moved that to a higher
position, using its old value for the new DECIMAL_INT flag, so that it
is representable within an unsigned char.
Example output:
demo.c:5:13: warning: result of '2^8' is 10; did you mean '1 << 8' (256)? [-Wxor-used-as-pow]
5 | int t2_8 = 2^8;
| ^
| --
| 1<<
demo.c:5:12: note: you can silence this warning by using a hexadecimal constant (0x2 rather than 2)
5 | int t2_8 = 2^8;
| ^

demo.c:21:15: warning: result of '10^6' is 12; did you mean '1e6'? [-Wxor-used-as-pow]
21 | int t10_6 = 10^6;

This moves all D front-end specific target definitions out of the main
target headers, and into its own header that is included by tm_d.h
instead of pulling in the same headers as tm_p.h.
This fixes the build on target configurations that pull in the default D
language target hooks, and subsequently trigger an error because the
definition of PREFERRED_DEBUGGING_TYPE is behind tm.h, the one header
that is avoided from being included in default-d.cc.

This defines the is_xxx_constructible_v and is_xxx_assignable_v variable
templates by using the built-ins directly. The actual logic for each one
is the same as the corresponding class template, but way using the
variable template doesn't need to instantiate the class template.
This means that the variable templates won't use the static assertions
checking for complete types, cv void or unbounded arrays, but that's OK
because the built-ins check those anyway. We could probably remove the
static assertions from the class templates, and maybe from all type
traits that use a built-in.

r13-2230-g390f94eee1ae69 redefined the internal logical operator traits
__and_, __or_ and __not_ as alias templates that directly resolve to
true_type or false_type. But it turns out using an alias template here
causes the traits to be less lazy than before because we now compute the
logical result immediately upon _specialization_ of the trait, and not
later upon _completion_ of the specialization.
So for example, in
using type = __and_<A, __not_<B>>;
we now compute the conjunction and thus instantiate A even though we're
in a context that doesn't require completion of the __and_. What's
worse is that we also compute the inner negation and thus instantiate B
(for the same reason), independent of the __and_ and the value of A!
Thus the traits are now less lazy and composable than before.
Fortunately, the fix is cheap and straightforward: redefine these traits
as class templates instead of as alias templates so that computation of
the logical result is triggered by completion, not by specialization.
libstdc++-v3/ChangeLog:
* include/std/type_traits (__or_, __and_, __not_): Redefine as a
class template instead of as an alias template.

vect_optimize_slp_pass always treats the starting layout as valid,
to avoid having to "optimise" when every possible choice is invalid.
But it gives the starting layout a high cost if it seems like the
target might reject it, in the hope that this will encourage other
(valid) layouts.
The testcase for PR106787 showed that this was flawed, since it was
triggering even in cases where the number of input lanes is different
from the number of output lanes. Picking such a high cost could also
make costs for loop-invariant nodes overwhelm the costs for inner-loop
nodes.
This patch makes the costing less aggressive by (a) restricting
it to N-to-N permutations and (b) assigning the maximum cost of
a permute.
gcc/
* tree-vect-slp.cc (vect_optimize_slp_pass::internal_node_cost):
Reduce the fallback cost to 1. Only use it if the number of
input lanes is equal to the number of output lanes.

In the PR we have two REDUC_PLUS SLP instances that share a common
load of stride 4. Each instance also has a unique contiguous load.
Initially all three loads are out of order, so have a nontrivial
load permutation. The layout pass puts them in order instead,
For the two contiguous loads it is possible to do this by adjusting the
SLP_LOAD_PERMUTATION to be { 0, 1, 2, 3 }. But a SLP_LOAD_PERMUTATION
of { 0, 4, 8, 12 } is rejected as unsupported, so the pass creates a
separate VEC_PERM_EXPR instead.
Later the 4-stride load's initial SLP_LOAD_PERMUTATION is rejected too,
so that the load gets replaced by an external node built from scalars.
We then have an external node feeding a VEC_PERM_EXPR.
VEC_PERM_EXPRs created in this way do not have any associated
SLP_TREE_SCALAR_STMTS. This means that they do not affect the
decision about which nodes should be in which subgraph for costing
purposes. If the VEC_PERM_EXPR is fed by a vect_external_def,
then the VEC_PERM_EXPR's input doesn't affect that decision either.
The net effect is that a shared VEC_PERM_EXPR fed by an external def
can appear in more than one subgraph. This triggered an ICE in
vect_schedule_node, which (rightly) expects to be called no more
than once for the same internal def.
There seemed to be many possible fixes, including:
(1) Replace unsupported loads with external defs *before* doing
the layout optimisation. This would avoid the need for the
VEC_PERM_EXPR altogether.
(2) If the target doesn't support a load in its original layout,
stop the layout optimisation from checking whether the target
supports loads in any new candidate layout. In other words,
treat all layouts as if they were supported whenever the
original layout is not in fact supported.
I'd rather not do this. In principle, the layout optimisation
could convert an unsupported layout to a supported one.
Selectively ignoring target support would work against that.
We could try to look specifically for loads that will need
to be decomposed, but that just seems like admitting that
things are happening in the wrong order.
(3) Add SLP_TREE_SCALAR_STMTS to VEC_PERM_EXPRs.
That would be OK for this case, but wouldn't be possible
for external defs that represent existing vectors.
(4) Make vect_schedule_slp share SCC info between subgraphs.
It feels like that's working around the partitioning problem
rather than a real fix though.
(5) Directly ensure that internal def nodes belong to a single
subgraph.
(1) is probably the best long-term fix, but (5) is much simpler.
The subgraph partitioning code already has a hash set to record
which nodes have been visited; we just need to convert that to a
map from nodes to instances instead.

Use TARGET_COMPUTE_MULTILIB to search the multi-lib reuse for riscv*-*-elf*,
according following rules:
1. Check ABI is same.
2. Check both has atomic extension or both don't have atomic extension.
- Because mix soft and hard atomic operation doesn't make sense and
won't work as expect.
3. Check current arch is superset of the target multi-lib arch.
- It might result slower performance or larger code size, but it
safe to run.
4. Pick most match multi-lib set if more than one multi-lib are pass
the above checking.
Example for how to select multi-lib:
We build code with -march=rv32imaf and -mabi=ilp32, and we have
following 5 multi-lib set:
1. rv32ia/ilp32
2. rv32ima/ilp32
3. rv32imf/ilp32
4. rv32imaf/ilp32f
5. rv32imafd/ilp32
The first and second multi-lib is safe to like, 3rd multi-lib can't
re-use becasue it don't have atomic extension, which is mismatch according
rule 2, and the 4th multi-lib can't re-use too due to the ABI mismatch,
the last multi-lib can't use since current arch is not superset of the
arch of multi-lib.
And emit error if not found suitable multi-lib set, the error message
only emit when link with standard libraries.
Example for when error will be emitted:
$ riscv64-unknown-elf-gcc -print-multi-lib
.;
rv32i/ilp32;@march=rv32i@mabi=ilp32
rv32im/ilp32;@march=rv32im@mabi=ilp32

Create a new hook to let target could override the multi-lib result,
the motivation is RISC-V might have very complicated multi-lib re-use
rule*, which is hard to maintain and use current multi-lib scripts,
we even hit the "argument list too long" error when we tried to add more
multi-lib reuse rule.
So I think it would be great to have a target specific way to determine
the multi-lib re-use rule, then we could write those rule in C, instead
of expand every possible case in MULTILIB_REUSE.

The compiler wrongly reports an error about the expected type not
matching the same-named found type in a return statement for a function
whose result type has unknown discriminants when the full type is tagged
and has an undefaulted discriminant, and the return expression is an object
initialized by a function call. The processing for return statements that
creates an actual subtype based on the return expression type's underlying
type when that type has discriminants, and converts the expression to
the actual subtype, should only be done when the underlying discriminated
type is mutable (i.e., has defaulted discriminants). Otherwise the
unchecked conversion to the actual subtype (of the underlying full type)
can lead to a resolution problem later within Expand_Simple_Function_Return
in the expansion of tag assignments (because the target type of the
conversion is a full view and does not match the partial view of
the function's result type).

Any multi-versioned function was implicitly declared as noexcept, which
leads to an abort if an exception is thrown inside the function.
The reason for this is that the function declaration is replaced by a
newly created dispatcher declaration, which has TREE_NOTHROW always set
to 1. Instead we need to set TREE_NOTHROW to the value of the original
declaration.
