c++: ICE with -Wlogical-op [PR107755]

Here we crash in the middle end because warn_logical_operator calls
build_range_check which calls various fold_* functions and those
don't work too well when we're still processing template trees.  For
instance here we crash because we're converting a RECORD_TYPE to bool.
At this point VIEW_CONVERT_EXPR<struct Foo>(b) hasn't yet been converted
to Foo::operator bool (&b).

I was excited to fix this with instantiation_dependent_expression_p
which can now be called from c-family/ as well, but the problem isn't
that the expression is dependent.  So, p_t_d it is.

ree: Fix -fcompare-debug issues in combine_reaching_defs [PR108573]

The PR78437 r7-4871 changes made combine_reaching_defs punt on
WORD_REGISTER_OPERATIONS targets if a setter of smaller than word
register has wider uses.  This unfortunately breaks -fcompare-debug,
because if such a use appears only in DEBUG_INSN(s), while all other
uses aren't wider than the setter, we can REE optimize it without -g
and not with -g.

Such decisions shouldn't be based on debug instructions.  We could try
to reset them or adjust in some other way after we decide to perform the
change, but at least on the testcase which used to fail on riscv64-linux
the
(debug_insn 8 7 9 2 (var_location:HI s (minus:HI (subreg:HI (and:DI (reg:DI 10 a0 [160])
                (const_int 1 [0x1])) 0)
        (subreg:HI (ashiftrt:DI (reg/v:DI 9 s1 [orig:151 l ] [151])
                (debug_expr:SI D#1)) 0))) "pr108573.c":12:5 -1
     (nil))
clearly doesn't care about the upper bits and I have hard time imaging how
could one end up with DEBUG_INSN which actually cares about those upper
bits.

So, the following patch just ignores uses on DEBUG_INSNs in this case,
if we run into something where we'd need to do something further later on,
let's deal with it when we have a testcase for it.

c++, openmp: Handle some OMP_*/OACC_* constructs during constant expression evaluation [PR108607]

While potential_constant_expression_1 handled most of OMP_* codes (by saying that
they aren't potential constant expressions), OMP_SCOPE was missing in that list.
I've also added OMP_SCAN, though that is less important (similarly to OMP_SECTION
it ought to appear solely inside of OMP_{FOR,SIMD} resp. OMP_SECTIONS).
As the testcase shows, it isn't enough, potential_constant_expression_1
can catch only some cases, as soon as one uses switch or ifs where at least
one of the possible paths could be constant expression, we can run into the
same codes during cxx_eval_constant_expression, so this patch handles those
there as well.

IBM zSystems: Make stack_tie to work with hard frame pointer

With this patch a scheduling barrier is created to prevent the insn
setting up the frame-pointer and instructions which save GPRs to the
stack to be swapped.  Otherwise broken CFI information would be
generated since the stack save insns would use a base register which
is not currently declared as holding the CFA.

Without -mpreserve-args this did not happen because the store multiple
we used for saving the GPRs would also cover the frame-pointer
register and therefore creates a dependency on the frame-pointer
hardreg. However, with this patch the stack_tie is emitted regardless
of -mpreserve-args since this in general appears to be the safer
approach.

restored.

middle-end/108500 - replace recursive domtree DFS traversal

The following replaces the recursive DFS traversal of the dominator

that we have recorded parents.

Bootstrapped and tested on x86_64-unknown-linux-gnu.

This makes r13-5325 somewhat obsolete, though not computing the

immediate CFG manipulations.

OK for trunk and later branch(es)?

Currently, 'gcc/testsuite/lib/gm2.exp:gm2_link_flags' doesn't set up
paths to compiler libraries (such as libgcc, which libstdc++
may depend on).  For example, I see my x86_64-pc-linux-gnu '-m32' testing
not pick up the build-tree libgcc, but instead some random system one,
which (expectedly) doesn't satisfy requirements of other build-tree
libraries:

..., and thus a lot of execution FAILs.

c++: fix ICE with -Wduplicated-cond [PR107593]

Here we crash because a CAST_EXPR, representing T(), doesn't have
its operand, and operand_equal_p's STRIP_ANY_LOCATION_WRAPPER doesn't
expect that.  (o_e_p is called from warn_duplicated_cond_add_or_warn.)

In the past we've adjusted o_e_p to better cope with template codes,
but in this case I think we just want to avoid attempting to warn
about inst-dependent expressions; I don't think I've ever envisioned
-Wduplicated-cond to warn about them.  Also destroy the chain when
an inst-dependent expression is encountered to not warn in
Wduplicated-cond4.C.

The ICE started with r12-6022, two-stage name lookup for overloaded
operators, which gave dependent operators a TREE_TYPE (in particular,
DEPENDENT_OPERATOR_TYPE), so we no longer bail out here in o_e_p:

  /* Similar, if either does not have a type (like a template id),
     they aren't equal.  */
  if (!TREE_TYPE (arg0) || !TREE_TYPE (arg1))
    return false;

modula2/108462 - duplicate install of static modula2 target libs

The following addresses the fact that libgm2 installs static libraries

and one performed as part of the install-data-local rule to a

This patch opts to keep the copy installed by libtool and removes
the extra installs in the install-data-local rules.

gccrs: Refactor TypeResolution to be a simple query based system

This patch refactors the type resolution system to introduce a new
interface

  bool query_type (HirId, TyTy::BaseType** result)

This is needed in order to properly support forward declared items. Our
name resolution system has two parts:

  1. Toplevel scan
  2. Item resolution

The toplevel scan gathers all the nesseacry 'names' into their respective
namespace by doing a full toplevel scan and generate canonical paths for
each item. The second pass is responsible for drilling down into each
structure or function to resolve each field or variable etc. This means
our name resolution system supports forward decalred items but our type
resolution system did not.

This patch removes the toplevel scan from our type resolution pass which
is not able to handle all cases such as a function with return type and
the type is decalred after the fact or a type alias to a type declared
after the fact. The name resolution mappings are resolved so when errors
occured here we got errors such as unable to lookup HirId 1234, which meant
yes we have 'resolved' this reference to this HirId but we are unable to
find any type information for it. This means we needed a new way to figure
out the type in a query based way.

This is where the new query_type inferface comes in so when we have an
HirId we want to resolve the mappings class allows us to figure out what
item this is such as:

  1. HIR::Item (normal HIR::Function, Struct, TypeAlias, ...)
  2. HIR::ImplItem (function, constant, ... within an impl-block)
  3. HIR::ImplBlock (Self type on an impl-block)
  4. HIR::ExternalItem (extern-block item)

The mappings class allows us to simply lookup these HIR nodes and then
call the relevant resolver class to compute the type. This patch does not
add support for self-referencial types but is the starting point to be able
to support such types.

gccrs: Create canonical process of compiling constant items

In order to compile a block expression constant, the simplest way for us
was to reuse what code we have and to generate an artifical function which
does not get added to the translation unit. The constant then becomes
a CALL_EXPR to this artifical function which we can pass to the constexpr
evaluator to resolve the result of this artifical 'CALL_EXPR'.

Before this patch we seperated the difference between block expressions
and non block expressions in constants. So for non block expressions we
simply compiled them as if it was a simple constant but this is not
guaranteed to be the case in rust, for example coercion sites can generate
temporaries during autoderef which we let the constant evaluator resolve
for us. This makes all constants handled in the same way to simplify the
logic here.

We simply hit a gcc_unreachable() on double borrows but it seems reasonable

borrow expression with a flag to be respected.

gccrs: const folding port

This changeset ports cp_global_trees structure which is used throughout the

to add and manipulate tree information during the c++ compilation process.
It is possible this is not needed in the Rust code and may be taken out later.
Also, the initialization function isn't being called from anywhere yet, so
we will need to find a suitable point for it.

i386: Fix up ix86_convert_const_wide_int_to_broadcast [PR108599]

The following testcase is miscompiled.  The problem is that during
RTL DSE we see a V4DI register is being loaded { 16, 16, 0, 0 }
value and DSE mostly works in terms of scalar modes, so it calls
movoi to set an OImode REG to (const_wide_int 0x100000000000000010)
and ix86_convert_const_wide_int_to_broadcast thinks it can compute
that value by broadcasting DImode 0x10.  While it is true that
for TImode result the broadcast could be used, for OImode/XImode
it can't be, because all but the lowest 2 HOST_WIDE_INTs aren't
present (so are 0 or -1 depending on sign), not 0x10 in this case.
The function checks if the least significant HOST_WIDE_INT elt
of the CONST_WIDE_INT is broadcastable from QI/HI/SI/DImode and then
  /* Check if OP can be broadcasted from VAL.  */
  for (int i = 1; i < CONST_WIDE_INT_NUNITS (op); i++)
    if (val != CONST_WIDE_INT_ELT (op, i))
      return nullptr;
That is needed of course, but nothing checks that
CONST_WIDE_INT_NUNITS (op) isn't too small for the mode in question.
I think if op would be 0 or -1, it ought to be never CONST_WIDE_INT,
but CONST_INT and so we can just punt whenever the number of
CONST_WIDE_INT elts is not the expected one.
