This patch introduces an optional hardening pass to catch unexpected
execution flows. Functions are transformed so that basic blocks set a
bit in an automatic array, and (non-exceptional) function exit edges
check that the bits in the array represent an expected execution path
in the CFG.
Functions with multiple exit edges, or with too many blocks, call an
out-of-line checker builtin implemented in libgcc. For simpler
functions, the verification is performed in-line.
-fharden-control-flow-redundancy enables the pass for eligible
functions, --param hardcfr-max-blocks sets a block count limit for
functions to be eligible, and --param hardcfr-max-inline-blocks
tunes the "too many blocks" limit for in-line verification.
-fhardcfr-skip-leaf makes leaf functions non-eligible.
Additional -fhardcfr-check-* options are added to enable checking at
exception escape points, before potential sibcalls, hereby dubbed
returning calls, and before noreturn calls and exception raises. A
notable case is the distinction between noreturn calls expected to
throw and those expected to terminate or loop forever: the default
setting for -fhardcfr-check-noreturn-calls, no-xthrow, performs
checking before the latter, but the former only gets checking in the
exception handler. GCC can only tell between them by explicit marking
noreturn functions expected to raise with the newly-introduced
expected_throw attribute, and corresponding ECF_XTHROW flag.

In order to detect invalid jumps in and out of intervening code in
imperfectly-nested loops, the front ends need to insert some sort of
marker to identify the structured block sequences that they push into
the inner body of the loop. The error checking happens in the
diagnose_omp_blocks pass, between gimplification and OMP lowering, so
we need both GENERIC and GIMPLE representations of these markers.
They are removed in OMP lowering so no subsequent passes need to know
about them.
This patch doesn't include any front-end changes to generate the new
data structures.

Many functions defined in our headers are declared 'static inline' which
is a C idiom whose use predates our move to C++ as the implementation
language. But in C++ the inline keyword is more than just a compiler
hint, and is sufficient to give the function the intended semantics.
In fact declaring a function both static and inline is a pessimization
since static effectively disables the desired definition merging
behavior enabled by inline, and is also a source of (harmless) ODR
violations when a static inline function gets called from a non-static
inline one (such as tree_operand_check calling tree_operand_length).
This patch mechanically fixes the vast majority of occurrences of this
anti-pattern throughout the compiler's headers via the command line
sed -i 's/^static inline/inline/g' gcc/*.h gcc/*/*.h
There's also a manual change to remove the redundant declarations
of is_ivar and lookup_category in gcc/objc/objc-act.cc which would
otherwise conflict with their modified definitions in objc-act.h
(due to the difference in staticness).
Besides fixing some ODR violations, this speeds up stage1 cc1plus by
about 2% and reduces the size of its text segment by 1.5MB.

My earlier patches gimplify the simplest non-side-effects assumptions
into if (cond) ; else __builtin_unreachable (); and throw the rest
on the floor.
The following patch attempts to do something with the rest too.
For -O0, it throws the more complex assumptions on the floor,
we don't expect optimizations and the assumptions are there to allow
optimizations. Otherwise arranges for the assumptions to be
visible in the IL as
.ASSUME (_Z2f4i._assume.0, i_1(D));
call where there is an artificial function like:
bool _Z2f4i._assume.0 (int i)
{
bool _2;
<bb 2> [local count: 1073741824]:
_2 = i_1(D) == 43;
return _2;
}
with the semantics that there is UB unless the assumption function
would return true.
Aldy, could ranger handle this? If it sees .ASSUME call,
walk the body of such function from the edge(s) to exit with the
assumption that the function returns true, so above set _2 [true, true]
and from there derive that i_1(D) [43, 43] and then map the argument
in the assumption function to argument passed to IFN_ASSUME (note,
args there are shifted by 1)?
During gimplification it actually gimplifies it into
[[assume (D.2591)]]
{
{
i = i + 1;
D.2591 = i == 44;
}
}
which is a new GIMPLE_ASSUME statement wrapping a GIMPLE_BIND and
specifying a boolean_type_node variable which contains the result.
The GIMPLE_ASSUME then survives just a couple of passes and is lowered
during gimple lowering into an outlined separate function and
IFN_ASSUME call. Variables declared inside of the
condition (both static and automatic) just change context, automatic
variables from the caller are turned into parameters (note, as the code
is never executed, I handle this way even non-POD types, we don't need to
bother pretending there would be user copy constructors etc. involved).
The assume_function artificial functions are then optimized until the
new assumptions pass which doesn't do much right now but I'd like to see
there the backwards ranger walk and filling up of SSA_NAME_RANGE_INFO
for the parameters.
There are a few further changes I'd like to do, like ignoring the
.ASSUME calls in inlining size estimations (but haven't figured out where
it is done), or for LTO arrange for the assume functions to be emitted
in all partitions that reference those (usually there will be just one,
unless code with the assumption got inlined, versioned etc.).

When not optimizing, we can't do anything useful with unreachability in
terms of code performance, so we might as well improve debugging by turning
__builtin_unreachable into a trap. I think it also makes sense to do this
when we're explicitly optimizing for the debugging experience.
In the PR richi suggested introducing an -funreachable-traps flag for this.
This functionality is already implemented as -fsanitize=unreachable
-fsanitize-trap=unreachable, and we want to share the implementation, but it
does seem useful to have a separate flag that isn't affected by the various
sanitization controls. -fsanitize=unreachable takes priority over
-funreachable-traps if both are enabled.
Jakub observed that this would slow down -O0 by default from running the
sanopt pass, so this revision avoids the need for sanopt by rewriting calls
introduced by the compiler immediately, and calls written by the user at
fold time. Many of the calls introduced by the compiler are also rewritten
immediately to ubsan calls when not trapping, which fixes ubsan-8b.C;
previously the call to f() was optimized away before sanopt. But this early
rewriting isn't practical for uses of __builtin_unreachable in
devirtualization and such, so sanopt rewriting is still done for
non-trapping sanitize.

gimple_set_location is mostly invoked on newly built GIMPLE statements, so
their location is UNKNOWN_LOCATION and setting it will clobber the warning

The following fixes wrongly used is_gimple_condexpr and makes
canonicalize_cond_expr_cond honor either, delaying final checking
to callers where all but two in ifcombine are doing the correct
thing already.
This fixes bugs but is now mainly in preparation for making
COND_EXPRs in GIMPLE assignments no longer have a GENERIC expression
as condition operand like we already transitioned VEC_COND_EXPR earlier.

This adds a flag to CONSTRUCTOR nodes indicating that for
clobbers this marks the end-of-life of storage as opposed to
just ending the lifetime of the object that occupied it.
The dangling pointer diagnostics uses CLOBBERs but is confused
by those emitted by the C++ frontend for example which emits
them for the second purpose at the start of CTORs. The issue
is also appearant for aarch64 in PR104092.
Distinguishing the two cases is also necessary for the PR90348 fix.
Since I'm going to add another flag I added an enum clobber_flags
and a defaulted argument to build_clobber plus a convenient way to
query the enum from the CTOR tree and specify it for gimple_clobber_p.
Since 'CLOBBER' is already taken and I needed a name for the unspecified
clobber we have now I used 'CLOBBER_UNDEF'.

This patch adds:
- gimple_num_args
- gimple_arg
- gimple_arg_ptr
for accessing rhs operands of an assignment, call or PHI. This is
similar to the existing gimple_get_lhs.
I guess there's a danger that these routines could be overused,
such as in cases where gimple_assign_rhs1 etc. would be more
appropriate. I think the routines are still worth having though.
These days, most new operations are added as internal functions rather
than tree codes, so it's useful to be able to handle assignments and
calls in a consistent way.
The patch also generalises the way that SLP child nodes map
to gimple stmt operands. This is useful for later patches.

Extend modref and tree-ssa-structalias to handle retslot flags.
Since retslot it essentially a hidden argument that is known to be write-only
we can do pretty much the same stuff as we do for regular parameters.
I plan to add static chain handling similar way.
We do not handle IPA propagation of retslot flags (where return slot is
initialized via return slot of other function). For this ipa-prop needs
to be extended to understand retslot as well.
Bootstrapped/regtested x86_64-linux, OK for the gimple bits?

This patch implements OpenMP 5.1 atomics (with clarifications from upcoming 5.2).
The most important changes are that it is now possible to write (for C/C++,
for Fortran it was possible before already) min/max atomics and more importantly
compare and exchange in various forms.
Also, acq_rel is now allowed on read/write and acq_rel/acquire are allowed on
update, and there are new compare, weak and fail clauses.

This patch implements the OpenMP 5.1 scope construct, which is similar
to worksharing constructs in many regards, but isn't one of them.
The body of the construct is encountered by all threads though, it can
be nested in itself or intermixed with taskgroup and worksharing etc.
constructs can appear inside of it (but it can't be nested in
worksharing etc. constructs). The main purpose of the construct
is to allow reductions (normal and task ones) without the need to
close the parallel and reopen another one.
If it doesn't have task reductions, it can be implemented without
any new library support, with nowait it just does the privatizations
at the start if any and reductions before the end of the body, with
without nowait emits a normal GOMP_barrier{,_cancel} at the end too.
For task reductions, we need to ensure only one thread initializes
the task reduction library data structures and other threads copy from that,
so a new GOMP_scope_start routine is added to the library for that.
It acts as if the start of the scope construct is a nowait worksharing
construct (that is ok, it can't be nested in other worksharing
constructs and all threads need to encounter the start in the same
order) which does the task reduction initialization, but as the body
can have other scope constructs and/or worksharing constructs, that is
all where we use this dummy worksharing construct. With task reductions,
the construct must not have nowait and ends with a GOMP_barrier{,_cancel},
followed by task reductions followed by GOMP_workshare_task_reduction_unregister.
Only C/C++ FE support is done.

This construct has been introduced as a replacement for master
construct, but unlike that construct is slightly more general,
has an optional clause which allows to choose which thread
will be the one running the region, it can be some other thread
than the master (primary) thread with number 0, or it could be no
threads or multiple threads (then of course one needs to be careful
about data races).
It is way too early to deprecate the master construct though, we don't
even have OpenMP 5.0 fully implemented, it has been deprecated in 5.1,
will be also in 5.2 and removed in 6.0. But even then it will likely
be a good idea to just -Wdeprecated warn about it and still accept it.
The patch also contains something I should have done much earlier,
for clauses that accept some integral expression where we only care
about the value, forces during gimplification that value into
either a min invariant (as before), SSA_NAME or a fresh temporary,
but never e.g. a user VAR_DECL, so that for those clauses we don't
need to worry about adjusting it.

This makes SLP discovery detect backedges by seeding the bst_map with
the node to be analyzed so it can be picked up from recursive calls.
This removes the need to discover backedges in a separate walk.
This enables SLP build to handle PHI nodes in full, continuing
the SLP build to non-backedges. For loop vectorization this
enables outer loop vectorization of nested SLP cycles and for
BB vectorization this enables vectorization of PHIs at CFG merges.
It also turns code generation into a SCC discovery walk to handle
irreducible regions and nodes only reachable via backedges where
we now also fill in vectorized backedge defs.
This requires sanitizing the SLP tree for SLP reduction chains even
more, manually filling the backedge SLP def.
This also exposes the fact that CFG copying (and edge splitting
until I fixed that) ends up with different edge order in the
copy which doesn't play well with the desired 1:1 mapping of
SLP PHI node children and edges for epilogue vectorization.
I've tried to fixup CFG copying here but this really looks
like a dead (or expensive) end there so I've done fixup in
slpeel_tree_duplicate_loop_to_edge_cfg instead for the cases
we can run into.
There's still NULLs in the SLP_TREE_CHILDREN vectors and I'm
not sure it's possible to eliminate them all this stage1 so the
patch has quite some checks for this case all over the place.
Bootstrapped and tested on x86_64-unknown-linux-gnu. SPEC CPU 2017

As mentioned in the PR, when compiling valgrind even on fairly small
testcase where in one larger function the location keeps oscillating
between a small line number and 8000-ish line number in the same file
we very quickly run out of all possible location_t numbers and because of
that emit non-sensical line numbers in .debug_line.
There are ways how to decrease speed of depleting location_t numbers
in libcpp, but the main reason of this is that we use
stream_input_location_now for streaming in location_t for gimple_location
and phi arg locations. libcpp strongly prefers that the locations
it is given are sorted by the different files and by line numbers in
ascending order, otherwise it depletes quickly no matter what and is much
more costly (many extra file changes etc.).
The reason for not caching those were the BLOCKs that were streamed
immediately after the location and encoded into the locations (and for PHIs
we failed to stream the BLOCKs altogether).
This patch enhances the location cache to handle also BLOCKs (but not for
everything, only for the spots we care about the BLOCKs) and also optimizes
the size of the LTO stream by emitting a single bit into a pack whether the
BLOCK changed from last case and only streaming the BLOCK tree if it
changed.

This patch removes the generation of HSAIL from the compiler, the HSA
offloading plugin from libgomp and the associated testsuite tests and
infrastructure bits from the respective testsuites.
Apart from removal of the obvious files, I removed bits that I found
by searching for HSA related terms and by re-tracing my steps and
looking at the patches that introduced HSA in the first place. I did
not remove everything these patches brought in, for example:
- the mechanism to pass offload-target specific info from the application to
the offloading plugin - but the same mechanism is also used to
communicate number of teams and the thread limit to all offload targets.
- run_func hook in gomp_device_descr stays too, although now it is
not used. If some future offload target would like the ability to
refuse to offload some functions, it can use it. It is easy to
remove as a follow-up if it is considered clutter, though.
- configure options --with-hsa-runtime=PATH, -with-hsa-runtime-include=PATH
and --with-hsa-runtime-lib=PATH rmeain because GCN uses them too.
- Surprisingly, GOMP_TARGET_ARG_HSA_KERNEL_ATTRIBUTES (a constant
from gomp-constants.h) appears in the source of the amdgcn libgomp
plugin, although I tend to think that code path is not ever used
and this patch certainly removes it from the compiler.
Nevertheless, it seems it has potential value beyond HSAIL and so
I've kept it, it can of course always be easily removed in the
future of GCN folk abandon it too.
- I assume constants OFFLOAD_TARGET_TYPE_HSA and GOMP_DEVICE_HSA
need to stay indefinitely too just so that no future offload
target picks that number.
- I have kept dg-require-effective-target
offload_device_nonshared_as requirement of thests which have it.
It is quite probable I missed some small HSA artifacts but those
should be easy to remove later as we find them.

The GIMPLE store merging pass doesn't merge STRING_CSTs in the general
case, although they are accepted by native_encode_expr; the reason is
that the pass only works with integral modes, i.e. with chunks whose
size is a power of two.
There are two possible ways of extending it to handle STRING_CSTs:
1) lift the condition of integral modes and treat STRING_CSTs as
other _CST nodes but with arbitrary size; 2) implement a specific
and separate handling for STRING_CSTs.
The attached patch implements 2) for the following reasons: on the
one hand, even in Ada where character strings are first-class citizens,
cases where merging STRING_CSTs with other *_CST nodes would be possible
are quite rare in practice; on the other hand, string concatenations
happen more naturally and frequently thanks to the "&" operator, giving
rise to merging opportunities.

The following testcase FAILs, because gimplify_body adds a GIMPLE_NOP only
when there are no statements in the function and with -g there is a
DEBUG_BEGIN_STMT, so it doesn't add it and due to -fno-tree-dce that never
gets removed afterwards. Similarly, if the body seq after gimplification
contains some DEBUG_BEGIN_STMTs plus a single gbind, then we could behave
differently between -g0 and -g, by using that gbind as the body in the -g0
case and not in the -g case.
This patch fixes that by ignoring DEBUG_BEGIN_STMTs (other debug stmts can't
appear at this point yet thankfully) during decisions and if we pick the
single gbind and there are DEBUG_BEGIN_STMTs next to it, it moves them into
the gbind.
While debugging this, I found also a bug in the gimple_seq_last_nondebug_stmt
function, for a seq that has a single non-DEBUG_BEGIN_STMT statement
followed by one or more DEBUG_BEGIN_STMTs it would return NULL rather than
the first statement.

The `serial' construct (cf. section 2.5.3 of the OpenACC 2.6 standard)
is equivalent to a `parallel' construct with clauses `num_gangs(1)
num_workers(1) vector_length(1)' implied.
These clauses are therefore not supported with the `serial'
construct. All the remaining clauses accepted with `parallel' are also
accepted with `serial'.
The `serial' construct is implemented like `parallel', except for
hardcoding dimensions rather than taking them from the relevant
clauses, in `expand_omp_target'.
Separate codes are used to denote the `serial' construct throughout the
middle end, even though the mapping of `serial' to an equivalent
`parallel' construct could have been done in the individual language
frontends. In particular, this allows to distinguish between compute
constructs in warnings, error messages, dumps etc.
