[Ada] Set dummy Etype for the fake __HEAP entity in GNATprove
GNATprove represents reads and writes via pointers as operations on a
fake __HEAP entity. This entity already had various properties set to
dummy values (e.g. Scope set to Standard_Standard), so that it can be
processed like other entities without crashing and not special-cased
everywhere. Now it also has a dummy Etype, so it can be processed with
Is_Single_Concurrent_Object.
The modified code is only executed by GNATprove; frontend is not

[Ada] New algorithm for Elaboration order v4.0
This patch introduces several changes to the new elaboration order
mechanism:
* The concept of "strong" and "weak" edges is introduced. Strong
edges are the byproduct of language-defined relations between
units, such as with clauses. Weak edges are the byproduct of
specilative invocations at elaboration time, which may or may not
take place depending on control flow.
* The elaboration order algorithm has been heavily modified to make
use of the strong and weak edges, and operate on units compiled
with different elaboration models.
* The elaboration order algorithm employs the following logic:
- Maintain two sets of vertices, one for all elaborable
vertices, and one for all waiting vertices.
- Pick the best elaborable vertex, and elaborate its component.
- If no such elaborable vertex is available, pick the best
weakly elaborable vertex whose unit has been compiled with the
dynamic model, and elaborate its component.
- If no such weakly elaborable vertex is available, then either
all vertices were already elaborated, or the graph contains a
cycle.
The elaboration of a component employs the same logic, with an
added step where all successors of some predecessor currently being
elaborated are notified that they have one fewer predecessor to
wait on. This may cause certain successors to become elaborable, in
which case they are moved from the set of waiting vertices to the
set of elaborable vertices.
* Three new GNATbind debug switches are introduced, -d_a, -d_b, and
-d_e, to eliminate the effects of pragmas Elaborate_All,
Elaborate_Body, and Elaborate respectively.
* The section on terminology is updated to include new entries.

This fixes a crash (or an assertion failure) during the processing done

because the front-end does not duplicate the structure of the parent

to go up to the declaration of the parent type, which may or may not be

The change also makes the processing more robust by falling back to the

PR91068: Fix MIPS fallout from IRA matched operand changes
PR91068 is a case in which we have (ignoring non-LRA alternatives):
[(set (match_operand:SI 0 "register_operand" "=l,d?")
(plus:SI (mult:SI (match_operand:SI 1 "register_operand" "d,d")
(match_operand:SI 2 "register_operand" "d,d"))
(match_operand:SI 3 "register_operand" "0,d")))
(clobber (match_scratch:SI 4 "=X,l"))
(clobber (match_scratch:SI 5 "=X,&d"))]
where the first alternative is one instruction but the second is two.
This is very similar to the case that my recent IRA patches were
supposed to help. The crucial difference is that the cheap
alternative requires a single-register class while the expensive
alternative uses general registers.
This makes a difference when one of operand 0 or 3 can naturally be
allocated to LO but the other can't. If IRA makes that allocation,
both alternatives require one reload of equal cost and so the first
alternative clearly wins.
However, if we say that tying operands 0 and 3 saves the cost of a full
move, then all other things being equal, IRA will prefer to allocate
both registers to the same GPR. The registers will then naturally
fit the second alternative.
This has a more drastic effect in the MIPS case than it should because
using the GPR alternative is much more expensive there than it appears
to the RA. But that's really a separate problem and something we were
able to live with before my IRA patch.
What makes tying less useful here is the fact that the tied register is
a single-register class. I think in those circumstances it's better not
to use tied operands at all and instead use "l" for the inputs.
Allocating the input to LO, and allocating the output to LO, then depend
naturally on class costs. If we decide to allocate at least one of them
to LO, we'll use the cheap alternative, otherwise we'll (correctly) use
the expensive alternative. This effectively restores the situation
before my IRA patch, but this time making the preference on the input
register more explicit.
I originally wrote the patterns in the early days of IRA, and certainly
well before LRA. I think they were largely influened by reload rather
than RA proper (see the comment above *mul_acc_si, which is all about
the reload behaviour). LRA copes with the two-"l" case just fine.
The patch may well cause problems for -mno-lra, but I think we should
cull that option anyway.

[s390] Fix ambiguous .md attribute uses
This patch is part of a series that fixes ambiguous attribute
uses in .md files, i.e. cases in which attributes didn't use
<ITER:ATTR> to specify an iterator, and in which <ATTR> could
have different values depending on the iterator chosen.
The vx-builtins.md part changes the choice of <mode> from the
implicit <VFCMP:mode> to an explicit <VF_HW:mode> (i.e. from the
mode of the comparison result to the mode of the operands being
compared). That seemed like the intended behaviour given later
patterns like vec_cmpeq<mode>_cc.
The use of BFP in the s390.md LNDFR pattern looks like a typo,
since the operand to (abs ...) has to have the same mode as the result.
The only effect before this series was to create some extra variants
that would never match, making it harmless apart from very minor code
bloat.

[Ada] Stabilization of Elaboration order v4.0
This patch introduces several changes to the new elaboration order
mechanism:
* Instantiations processed in the context of invocation graph
encoding now yield a relation which is later transformed into an
invocation edge. This ensures that the unit where the instantiation
resides properly depends on the unit where the body of the generic
is.
* The diagnostics of cycles that involve invocation edges now use a
set to avoid infinite recursion when visiting paths that represent
recursive code.
* Various diagnostics that suggest the use of switches have been
updated to indicate which tool the switches apply to.
* Bindo can now output the dependencies of various units that specify
why a predecessor unit must be elaborated prior to a successor
unit. This functionality implements binder switch -e (output
complete list of elaboration order dependencies).
* The output of the elaboration order is now identical to that
emitted by Binde.
* The nature of the invocation graph encoding is now recorded in the
ALI record rather than the Unit record of a unit. This ensures that
both the spec and body share the same encoding kind.
* A section on debugging elaboration order issues is now available in
Bindo.

[Ada] Diagnostics in Elaboration order v4.0
This patch introduces several changes to the new elaboration order
mechanism:
* The library graph can now discover, store, and organize the various
cycles it contains.
* The elaboration order mechanism can now diagnose one or all cycles
within the library graph. Diagnostics consist of describing the
reason for the cycle, listing all units comprising the circuit, and
offering suggestions on how to break the cycle.
The patch also modifies unit ALI to hide all invocation-related data
structures and several implementation-specific types by relocating them
in the body of the unit.
The patch cleans up most children of Bindo by using better names of
routines and formal parameters.

introduce EH_ELSE_EXPR tree and gimplifier
I found GIMPLE_EH_ELSE offered exactly the semantics I needed for some
Ada changes yet to be contributed, but GIMPLE_EH_ELSE was only built
by GIMPLE passes, and I needed to build earlier something that
eventually became GIMPLE_EH_ELSE.
This patch does that, introducing an EH_ELSE_EXPR tree, and logic to
dump it and to gimplify it.

* doc/generic.texi (Cleanups): Document EH_ELSE_EXPR.
* except.c: Likewise.
* expr.c (expand_expr_real_1): Reject it.
* gimplify.c (gimplify_expr): Gimplify it, within
TRY_FINALLY_EXPR.
* tree-dump.c (dequeue_and_dump): Dump it.
* tree-pretty-print.c (dump_generic_node): Likewise.
* tree.c (block_may_fallthru): Handle it.
* tree.def (EH_ELSE_EXPR): Introduce it.
* gimple-pretty-print.c (dump_gimple_try): Dump TRY_FINALLY
with GIMPLE_EH_ELSE as try/finally/else.
