libstdc++: Add lightweight replacement for std::numeric_limits (PR 92546)
Many uses of std::numeric_limits in C++17 and C++20 features only really
need the min(), max() and digits constants for integral types. By adding
__detail::__int_limits we can avoid including the whole <limits> header.
The <limits> header isn't especially large, but avoiding it still gives
small savings in compilation time and memory usage for the compiler.
There are also C++11 features that could benefit from this change (e.g.
<bits/hashtable_policy.h> and <bits/uniform_int_dist.h>) but I won't
change those until stage 1.
The implementation of __int_limits assumes two's complement integers,
which is true for all targets supported by GCC.

libstdc++: Move some ranges algos to a new header <bits/ranges_algobase.h>
This roughly mirrors the existing split between <bits/stl_algo.h> and

header to avoid including all of of <bits/ranges_algo.h>.

libstdc++: Implement C++20 range adaptors
This patch implements [range.adaptors]. It also includes the changes from P3280
and P3278 and P3323, without which many standard examples won't work.
The implementation is mostly dictated by the spec and there was not much room
for implementation discretion. The most interesting part that was not specified
by the spec is the design of the range adaptors and range adaptor closures,
which I tried to design in a way that minimizes boilerplate and statefulness (so
that e.g. the composition of two stateless closures is stateless).
What is left unimplemented is caching of calls to begin() in filter_view,
drop_view and reverse_view, which is required to guarantee that begin() has
amortized constant time complexity. I can implement this in a subsequent patch.
"Interesting" parts of the patch are marked with XXX comments.

libstdc++: Implement C++20 range adaptors
This patch implements [range.adaptors]. It also includes the changes from P3280
and P3278 and P3323, without which many standard examples won't work.
The implementation is mostly dictated by the spec and there was not much room
for implementation discretion. The most interesting part that was not specified
by the spec is the design of the range adaptors and range adaptor closures,
which I tried to design in a way that minimizes boilerplate and statefulness (so
that e.g. the composition of two stateless closures is stateless).
What is left unimplemented is caching of calls to begin() in filter_view,
drop_view and reverse_view, which is required to guarantee that begin() has
amortized constant time complexity. I can implement this in a subsequent patch.
"Interesting" parts of the patch are marked with XXX comments.

libstdc++: Implement C++20 constrained algorithms
This patch implements the C++20 ranges overloads for the algorithms in
[algorithms]. Most of the algorithms were reimplemented, with each of their
implementations very closely following the existing implementation in
bits/stl_algo.h and bits/stl_algobase.h. The reason for reimplementing most of
the algorithms instead of forwarding to their STL-style overload is because
forwarding cannot be conformantly and efficiently performed for algorithms that
operate on non-random-access iterators. But algorithms that operate on random
access iterators can safely and efficiently be forwarded to the STL-style
implementation, and this patch does so for push_heap, pop_heap, make_heap,
sort_heap, sort, stable_sort, nth_element, inplace_merge and stable_partition.
What's missing from this patch is debug-iterator and container specializations
that are present for some of the STL-style algorithms that need to be ported
over to the ranges algos. I marked them missing at TODO comments. There are
also some other minor outstanding TODOs.
The code that could use the most thorough review is ranges::__copy_or_move,
ranges::__copy_or_move_backward, ranges::__equal and
ranges::__lexicographical_compare. In the tests, I tried to test the interface
of each new overload, as well as the correctness of the new implementation.

libstdc++: Fix conformance issues in <stop_token> (PR92895)
Fix synchronization issues in <stop_token>. Replace shared_ptr with
_Stop_state_ref and a reference count embedded in the shared state.

also tracks whether a stop request has been made and how many
stop_source objects share ownership of the state.

[C++ coroutines] Initial implementation.
This is the squashed version of the first 6 patches that were split to
facilitate review.
The changes to libiberty (7th patch) to support demangling the co_await
operator stand alone and are applied separately.
The patch series is an initial implementation of a coroutine feature,
expected to be standardised in C++20.
Standardisation status (and potential impact on this implementation)
--------------------------------------------------------------------
The facility was accepted into the working draft for C++20 by WG21 in
February 2019. During following WG21 meetings, design and national body
comments have been reviewed, with no significant change resulting.
The current GCC implementation is against n4835 [1].
At this stage, the remaining potential for change comes from:
* Areas of national body comments that were not resolved in the version we
have worked to:
(a) handling of the situation where aligned allocation is available.
(b) handling of the situation where a user wants coroutines, but does not
want exceptions (e.g. a GPU).
* Agreed changes that have not yet been worded in a draft standard that we
have worked to.
It is not expected that the resolution to these can produce any major
change at this phase of the standardisation process. Such changes should be
limited to the coroutine-specific code.
ABI
---
The various compiler developers 'vendors' have discussed a minimal ABI to
allow one implementation to call coroutines compiled by another.
This amounts to:
1. The layout of a public portion of the coroutine frame.
Coroutines need to preserve state across suspension points, the storage for
this is called a "coroutine frame".
The ABI mandates that pointers into the coroutine frame point to an area
begining with two function pointers (to the resume and destroy functions
described below); these are immediately followed by the "promise object"
described in the standard.
This is sufficient that the builtins can take a coroutine frame pointer and
determine the address of the promise (or call the resume/destroy functions).
2. A number of compiler builtins that the standard library might use.
These are implemented by this patch series.
3. This introduces a new operator 'co_await' the mangling for which is also
agreed between vendors (and has an issue filed for that against the upstream
c++abi). Demangling for this is added to libiberty in a separate patch.
The ABI has currently no target-specific content (a given psABI might elect
to mandate alignment, but the common ABI does not do this).
Standard Library impact
-----------------------
The current implementations require addition of only a single header to
the standard library (no change to the runtime). This header is part of
the patch.
GCC Implementation outline
--------------------------
The standard's design for coroutines does not decorate the definition of
a coroutine in any way, so that a function is only known to be a coroutine
when one of the keywords (co_await, co_yield, co_return) is encountered.
This means that we cannot special-case such functions from the outset, but
must process them differently when they are finalised - which we do from
"finish_function ()".
At a high level, this design of coroutine produces four pieces from the
original user's function:
1. A coroutine state frame (taking the logical place of the activation
record for a regular function). One item stored in that state is the
index of the current suspend point.
2. A "ramp" function
This is what the user calls to construct the coroutine frame and start
the coroutine execution. This will return some object representing the
coroutine's eventual return value (or means to continue it when it it
suspended).
3. A "resume" function.
This is what gets called when a the coroutine is resumed when suspended.
4. A "destroy" function.
This is what gets called when the coroutine state should be destroyed
and its memory released.
The standard's coroutines involve cooperation of the user's authored function
with a provided "promise" class, which includes mandatory methods for
handling the state transitions and providing output values. Most realistic
coroutines will also have one or more 'awaiter' classes that implement the
user's actions for each suspend point. As we parse (or during template
expansion) the types of the promise and awaiter classes become known, and can
then be verified against the signatures expected by the standard.
Once the function is parsed (and templates expanded) we are able to make the
transformation into the four pieces noted above.
The implementation here takes the approach of a series of AST transforms.
The state machine suspend points are encoded in three internal functions
(one of which represents an exit from scope without cleanups). These three
IFNs are lowered early in the middle end, such that the majority of GCC's
optimisers can be run on the resulting output.
As a design choice, we have carried out the outlining of the user's function
in the front end, and taken advantage of the existing middle end's abilities
to inline and DCE where that is profitable.
Since the state machine is actually common to both resumer and destroyer
functions, we make only a single function "actor" that contains both the
resume and destroy paths. The destroy function is represented by a small
stub that sets a value to signal the use of the destroy path and calls the
actor. The idea is that optimisation of the state machine need only be done
once - and then the resume and destroy paths can be identified allowing the
middle end's inline and DCE machinery to optimise as profitable as noted
above.
The middle end components for this implementation are:
A pass that:
1. Lowers the coroutine builtins that allow the standard library header to
interact with the coroutine frame (these fairly simple logical or
numerical substitution of values, given a coroutine frame pointer).
2. Lowers the IFN that represents the exit from state without cleanup.
Essentially, this becomes a gimple goto.
3. Sets the final size of the coroutine frame at this stage.
A second pass (that requires the revised CFG that results from the lowering
of the scope exit IFNs in the first).
1. Lower the IFNs that represent the state machine paths for the resume and
destroy cases.
Patches squashed into this commit:
[C++ coroutines 1] Common code and base definitions.
This part of the patch series provides the gating flag, the keywords,
cpp defines etc.
[C++ coroutines 2] Define builtins and internal functions.
This part of the patch series provides the builtin functions
used by the standard library code and the internal functions
used to implement lowering of the coroutine state machine.
[C++ coroutines 3] Front end parsing and transforms.
There are two parts to this.
1. Parsing, template instantiation and diagnostics for the standard-
mandated class entries.
The user authors a function that becomes a coroutine (lazily) by
making use of any of the co_await, co_yield or co_return keywords.
Unlike a regular function, where the activation record is placed on the
stack, and is destroyed on function exit, a coroutine has some state that
persists between calls - the 'coroutine frame' (thus analogous to a stack
frame).
We transform the user's function into three pieces:
1. A so-called ramp function, that establishes the coroutine frame and
begins execution of the coroutine.
2. An actor function that contains the state machine corresponding to the
user's suspend/resume structure.
3. A stub function that calls the actor function in 'destroy' mode.
The actor function is executed:
* from "resume point 0" by the ramp.
* from resume point N ( > 0 ) for handle.resume() calls.
* from the destroy stub for destroy point N for handle.destroy() calls.
The C++ coroutine design described in the standard makes use of some helper
methods that are authored in a so-called "promise" class provided by the
user.
At parse time (or post substitution) the type of the coroutine promise
will be determined. At that point, we can look up the required promise
class methods and issue diagnostics if they are missing or incorrect. To
avoid repeating these actions at code-gen time, we make use of temporary
'proxy' variables for the coroutine handle and the promise - which will
eventually be instantiated in the coroutine frame.
Each of the keywords will expand to a code sequence (although co_yield is
just syntactic sugar for a co_await).
We defer the analysis and transformatin until template expansion is
complete so that we have complete types at that time.
2. AST analysis and transformation which performs the code-gen for the
outlined state machine.
The entry point here is morph_fn_to_coro () which is called from
finish_function () when we have completed any template expansion.
This is preceded by helper functions that implement the phases below.
The process proceeds in four phases.
A Initial framing.
The user's function body is wrapped in the initial and final suspend
points and we begin building the coroutine frame.
We build empty decls for the actor and destroyer functions at this
time too.
When exceptions are enabled, the user's function body will also be
wrapped in a try-catch block with the catch invoking the promise
class 'unhandled_exception' method.
B Analysis.
The user's function body is analysed to determine the suspend points,
if any, and to capture local variables that might persist across such
suspensions. In most cases, it is not necessary to capture compiler
temporaries, since the tree-lowering nests the suspensions correctly.
However, in the case of a captured reference, there is a lifetime
extension to the end of the full expression - which can mean across a
suspend point in which case it must be promoted to a frame variable.
At the conclusion of analysis, we have a conservative frame layout and
maps of the local variables to their frame entry points.
C Build the ramp function.
Carry out the allocation for the coroutine frame (NOTE; the actual size
computation is deferred until late in the middle end to allow for future
optimisations that will be allowed to elide unused frame entries).
We build the return object.
D Build and expand the actor and destroyer function bodies.
The destroyer is a trivial shim that sets a bit to indicate that the
destroy dispatcher should be used and then calls into the actor.
The actor function is the implementation of the user's state machine.
The current suspend point is noted in an index.
Each suspend point is encoded as a pair of internal functions, one in
the relevant dispatcher, and one representing the suspend point.
During this process, the user's local variables and the proxies for the
self-handle and the promise class instanceare re-written to their
coroutine frame equivalents.
The complete bodies for the ramp, actor and destroy function are passed
back to finish_function for folding and gimplification.
[C++ coroutines 4] Middle end expanders and transforms.
The first part of this is a pass that provides:
* expansion of the library support builtins, these are simple boolean
or numerical substitutions.
* The functionality of implementing an exit from scope without cleanup
is performed here by lowering an IFN to a gimple goto.
This pass has to run for non-coroutine functions, since functions calling
the builtins are not necessarily coroutines (i.e. they are implementing the
library interfaces which may be called from anywhere).
The second part is the expansion of the coroutine IFNs that describe the
state machine connections to the dispatchers. This only has to be run
for functions that are coroutine components. The work done by this pass
is:
In the front end we construct a single actor function that contains
the coroutine state machine.
The actor function has three entry conditions:
1. from the ramp, resume point 0 - to initial-suspend.
2. when resume () is executed (resume point N).
3. from the destroy () shim when that is executed.
The actor function begins with two dispatchers; one for resume and
one for destroy (where the initial entry from the ramp is a special-
case of resume point 0).
Each suspend point and each dispatch entry is marked with an IFN such
that we can connect the relevant dispatchers to their target labels.
So, if we have:
CO_YIELD (NUM, FINAL, RES_LAB, DEST_LAB, FRAME_PTR)
This is await point NUM, and is the final await if FINAL is non-zero.
The resume point is RES_LAB, and the destroy point is DEST_LAB.
We expect to find a CO_ACTOR (NUM) in the resume dispatcher and a
CO_ACTOR (NUM+1) in the destroy dispatcher.
Initially, the intent of keeping the resume and destroy paths together
is that the conditionals controlling them are identical, and thus there
would be duplication of any optimisation of those paths if the split
were earlier.
Subsequent inlining of the actor (and DCE) is then able to extract the
resume and destroy paths as separate functions if that is found
profitable by the optimisers.
Once we have remade the connections to their correct postions, we elide
the labels that the front end inserted.
[C++ coroutines 5] Standard library header.
This provides the interfaces mandated by the standard and implements
the interaction with the coroutine frame by means of inline use of
builtins expanded at compile-time. There should be a 1:1 correspondence
with the standard sections which are cross-referenced.
There is no runtime content.
At this stage, we have the content in an inline namespace "__n4835" for
the CD we worked to.
[C++ coroutines 6] Testsuite.
There are two categories of test:
1. Checks for correctly formed source code and the error reporting.
2. Checks for transformation and code-gen.
The second set are run as 'torture' tests for the standard options
set, including LTO. These are also intentionally run with no options
provided (from the coroutines.exp script).
