This adds an alternate debug_dump_context similar to the one for
selftests but for interactive debugging routines. This allows
to share code between user-visible dumping via the dump_* API

now.

GCC 4.2 due to PR33916 miscompiles temp_dump_context ctor, because it doesn't
zero initialize the whole dump_context temporary on which it runs the static
get method and during destruction of the temporary an uninitialized pointer
is deleted.
More recent GCC versions properly zero initialize it and ideally optimize away
the construction/destruction of the temporary, as it isn't used for anything,
but there is no reason to create the temporary, static member functions can
be called without an associated object.

The dump_* API attempts to capture emission location metadata for the
various dump messages, but looking in -fsave-optimization-record shows
that many dump messages are lacking useful impl_location values, instead
having this location within dumpfile.c:
"impl_location": {
"file": "../../src/gcc/dumpfile.c",
"function": "ensure_pending_optinfo",
"line": 1169
},
The problem is that the auto-capturing of dump_impl_location_t is tied to
dump_location_t, and this is tied to the dump_*_loc calls. If a message
comes from a dump_* call without a "_loc" suffix (e.g. dump_printf), the
current code synthesizes the dump_location_t within
dump_context::ensure_pending_optinfo, and thus saves the useless
impl_location seen above.
This patch fixes things by changing the dump_* API so that, rather than
taking a dump_flags_t, they take a new class dump_metadata_t, which is
constructed from a dump_flags_t, but captures the emission location.
Hence e.g.:
dump_printf (MSG_NOTE, "some message\n");
implicitly builds a dump_metadata_t wrapping the MSG_NOTE and the
emission location. If there are several dump_printf calls without
a dump_*_loc call, the emission location within the optinfo is that
of the first dump call within it.
The patch updates selftest::test_capture_of_dump_calls to verify
that the impl location of various dump_* calls is captured. I also
verified things manually.

PR tree-optimization/87025 reports an ICE within
-fsave-optimization-record's optrecord_json_writer.
The issue is that dump_context::begin_scope creates an optinfo
of kind OPTINFO_KIND_SCOPE, but fails to call
dump_context::end_any_optinfo, so the optinfo for the scope remains
pending.
The JSON writer would normally push a JSON array for the "scope" optinfo
when the latter is emitted. However, if a dump_* call happens that
doesn't flush the "scope" optinfo e.g. dump_printf (as opposed to
dump_printf_loc), that dump_ call is added to the pending optinfo, and
optinfo::handle_dump_file_kind changes the pending optinfo's m_kind
(e.g. to OPTINFO_KIND_NOTE). Hence when the pending optinfo is
eventually emitted, it isn't OPTINFO_KIND_SCOPE anymore, and hence
the JSON writer doesn't create and push a JSON array for it, leading
to dump_context's view of scopes getting out-of-sync with that of
the JSON writer's.
Later, dump_context::end_scope unconditionally tries to pop the JSON scope
array, but no JSON scope array was added, leading to an assertion
failure (or crash).
The fix is to call dump_context::end_any_optinfo immediately after
creating the scope optinfo, so that it is emitted immediately, ensuring
that the JSON writer stays in-sync with the dump_context.

As work towards fixing PR tree-optimization/87025, this patch
eliminates global state from optinfo-emit-json.cc in favor
of adding an optional m_json_writer field to dump_context,
replacing the m_forcibly_enable_optinfo flag.
This allows for writing selftests for the interaction of the
JSON-building code with the dumpfile.c code.
In particular, the existing selftest that created optinfo
instances now exercise the JSON-building code (although no
JSON is actually written out).
The patch also simplifies the layering by replacing optinfo::emit ()
with dump_context::emit_optinfo, so that dump_context has
responsibility for keeping track of dump destinations.

If called when !dump_enabled_p, the dump_* functions effectively do
nothing, but as of r263178 this doing "nothing" involves non-trivial
work internally.
I wasn't sure whether the dump_* functions should assert that
dump_enabled_p ()
is true when they're called, or if they should bail out immediately
for this case, so in this patch I implemented both, so that we get
an assertion failure, and otherwise bail out for the case where
!dump_enabled_p when assertions are disabled.
The patch also fixes all of the places I found during testing
(on x86_64-pc-linux-gnu) that call into dump_* but which
weren't guarded by

This patch implements support for %C in dump_printf for dumping
cgraph_node *.
(I would have preferred to have a code for printing symtab_node *
and both subclasses, but there doesn't seem to be a good way for
-Wformat to handle inheritance, so, failing that, I went with
this approach).

* c-format.c (local_cgraph_node_ptr_node): New variable.
(gcc_dump_printf_char_table): Add entry for %C.
(get_pointer_to_named_type): New function, taken from the handling
code for "gimple *" from...

This is v3 of the patch; previous versions were:
v2: https://gcc.gnu.org/ml/gcc-patches/2018-07/msg00446.html
v1: https://gcc.gnu.org/ml/gcc-patches/2018-06/msg01462.html
This patch introduces a class opt_problem, along with wrapper
classes for bool (opt_result) and for pointers (e.g. opt_loop_vec_info
for loop_vec_info).
opt_problem instances are created when an optimization problem
is encountered, but only if dump_enabled_p. They are manually
propagated up the callstack, and are manually reported at the
"top level" of an optimization if dumping is enabled, to give the user
a concise summary of the problem *after* the failure is reported.
In particular, the location of the problematic statement is
captured and emitted, rather than just the loop's location.
For example:
no-vfa-vect-102.c:24:3: missed: couldn't vectorize loop
no-vfa-vect-102.c:27:7: missed: statement clobbers memory: __asm__ __volatile__("" : : : "memory");
Changed in v3:
* This version bootstraps and passes regression testing (on
x86_64-pc-linux-gnu).
* added selftests, to exercise the opt_problem machinery
* removed the "bool to opt_result" ctor, so that attempts to
use e.g. return a bool from an opt_result-returning function
will fail at compile time
* use formatted printing within opt_problem ctor to replace the
various dump_printf_loc calls
* dropped i18n
* changed the sense of vect_analyze_data_ref_dependence's return
value (see the ChangeLog)
* add MSG_PRIORITY_REEMITTED, so that -fopt-info can show the
messages, without them messing up the counts in scan-tree-dump-times
in DejaGnu tests

This patch introduces a verbosity level to dump messages:
"user-facing" vs "internals".
By default, messages at the top-level dump scope are "user-facing",
whereas those that are in nested scopes are implicitly "internals",
and are filtered out by -fopt-info unless a new "-internals" sub-option
of "-fopt-info" is supplied (intended purely for use by GCC developers).
Dumpfiles are unaffected by the change.
Given that the vectorizer is the only subsystem using AUTO_DUMP_SCOPE
(via DUMP_VECT_SCOPE), this only affects the vectorizer.
Filtering out these implementation-detail messages goes a long way
towards making -fopt-info-vec-all more accessible to advanced end-users;
the follow-up patch restores the most pertinent missing details.

Attempts to dump via -fopt-info from a plugin pass fail, due
to the dfi->alt_state for such passes never being set.
This is because the -fopt-info options were being set up per-pass
during option-parsing (via gcc::dump_manager::opt_info_enable_passes),
but this data was not retained or used it for passes created later
(for plugins and target-specific passes).
This patch fixes the issue by storing the -fopt-info options into
gcc::dump_manager, refactoring the dfi-setup code out of
opt_info_enable_passes, and reusing it for such passes, fixing the
issue. The patch adds a demo plugin to test that dumping from a
plugin works.

MSG_{OPTIMIZED_LOCATIONS|MISSED_OPTIMIZATION}
As noted at Cauldron, dumpfile.c currently emits "note: " for all kinds
of dump message, so that (after filtering) there's no distinction between
MSG_OPTIMIZED_LOCATIONS vs MSG_NOTE vs MSG_MISSED_OPTIMIZATION in the
textual output.
This patch changes dumpfile.c so that the "note: " varies to show
which MSG_* was used, with the string prefix matching that used for
filtering in -fopt-info, hence e.g.
directive_unroll_3.f90:24:0: optimized: loop unrolled 7 times
and:
pr19210-1.c:24:3: missed: missed loop optimization: niters analysis ends up with assumptions.
The patch adds "dg-optimized" and "dg-missed" directives for use
in the testsuite for matching these (with -fopt-info on stderr; they
don't help for dumpfile output).
The patch also converts the various problem-reporting dump messages
in coverage.c:get_coverage_counts to use MSG_MISSED_OPTIMIZATION
rather than MSG_OPTIMIZED_LOCATIONS, as the docs call out "optimized"
as
"information when an optimization is successfully applied",
whereas "missed" is for
"information about missed optimizations",
and problems with profile data seem to me to fall much more into the
latter category than the former. Doing so requires converting a few
tests from using "-fopt-info" (which is implicitly
"-fopt-info-optimized-optall") to getting the "missed" optimizations.
Changing them to "-fopt-info-missed" added lots of noise from the
vectorizer, so I changed these tests to use "-fopt-info-missed-ipa".
gcc/ChangeLog:
* coverage.c (get_coverage_counts): Convert problem-reporting dump
messages from MSG_OPTIMIZED_LOCATIONS to MSG_MISSED_OPTIMIZATION.
* dumpfile.c (kind_as_string): New function.
(dump_loc): Rather than a hardcoded prefix of "note: ", use
kind_as_string to vary the prefix based on dump_kind.

In r262891 I reimplemented this call:
dump_printf_loc (MSG_NOTE, loc, "=== %s ===\n", name);
in dump_begin_scope to use direct calls to dump_loc:
if (dump_file)
{
dump_loc (MSG_NOTE, dump_file, loc.get_location_t ());
fprintf (dump_file, "=== %s ===\n", name);
}
if (alt_dump_file)
{
dump_loc (MSG_NOTE, alt_dump_file, loc.get_location_t ());
fprintf (alt_dump_file, "=== %s ===\n", name);
}
However ::dump_loc doesn't filter with pflags and alt_flags.
This lead to stray output of the form:
test.cpp:1:6: note: test.cpp:1:11: note:
when using -fopt-info with "optimized" or "missed".
This patch adds this missing filtering, eliminating the stray partial
note output.

This patch converts dump_print and dump_printf_loc from using
printf (and thus ATTRIBUTE_PRINTF) to using a new pretty-printer
based on pp_format, which supports formatting middle-end types.
In particular, the following codes are implemented (in addition
to the standard pretty_printer ones):
%E: gimple *:
Equivalent to: dump_gimple_expr (MSG_*, TDF_SLIM, stmt, 0)
%G: gimple *:
Equivalent to: dump_gimple_stmt (MSG_*, TDF_SLIM, stmt, 0)
%T: tree:
Equivalent to: dump_generic_expr (MSG_*, arg, TDF_SLIM).
Hence it becomes possible to convert e.g.:
if (dump_enabled_p ())
{
dump_printf_loc (MSG_MISSED_OPTIMIZATION, vect_location,
"not vectorized: different sized vector "
"types in statement, ");
dump_generic_expr (MSG_MISSED_OPTIMIZATION, TDF_SLIM, vectype);
dump_printf (MSG_MISSED_OPTIMIZATION, " and ");
dump_generic_expr (MSG_MISSED_OPTIMIZATION, TDF_SLIM, nunits_vectype);
dump_printf (MSG_MISSED_OPTIMIZATION, "\n");
}
into a one-liner:
if (dump_enabled_p ())
dump_printf_loc (MSG_MISSED_OPTIMIZATION, vect_location,
"not vectorized: different sized vector "
"types in statement, %T and %T\n",
vectype, nunits_vectype);
Unlike regular pretty-printers, this one captures optinfo_item
instances for the formatted chunks as appropriate, so that when
written out to a JSON optimization record, the relevant parts of
the message are labelled by type, and by source location (so that
e.g. %G is entirely equivalent to using dump_gimple_stmt).
dump_printf and dump_printf_loc become marked with
ATTRIBUTE_GCC_DUMP_PRINTF, which the patch also implements.

With the addition of optinfo, the various dump_* calls had three parts:
- optionally print to dump_file
- optionally print to alt_dump_file
- optionally make an optinfo_item and add it to the pending optinfo,
creating it for dump_*_loc calls.
However, this split makes it difficult to implement the formatted dumps
later in patch kit, so as enabling work towards that, this patch removes
the above split, so that all dumping within the dump_* API goes through
optinfo_item.
In order to ensure that the dumps to dump_file and alt_dump_file are
processed immediately (rather than being buffered within the pending
optinfo for consolidation), this patch introduces the idea of "immediate"
optinfo_item destinations vs "non-immediate" destinations.
The patch also adds selftest coverage of what's printed, and of scopes.
This adds two allocations per dump_* call when dumping is enabled.
I'm assuming that this isn't a problem, as dump_enabled_p is normally
false. There are ways of optimizing it if it is an issue (by making
optinfo_item instances become temporaries that borrow the underlying
buffer), but they require nontrivial changes, so I'd prefer to leave
that for another patch kit, if it becomes necessary.

leads to a JSON file being written out, recording the dump_* calls
made (via the optinfo infrastructure).

This patch is the main part of PR85694. The aim is to recognise at least:
signed char *a, *b, *c;
...
for (int i = 0; i < 2048; i++)
c[i] = (a[i] + b[i]) >> 1;
as an over-widening pattern, since the addition and shift can be done
on shorts rather than ints. However, it ended up being a lot more
general than that.
The current over-widening pattern detection is limited to a few simple
cases: logical ops with immediate second operands, and shifts by a
constant. These cases are enough for common pixel-format conversion
and can be detected in a peephole way.
The loop above requires two generalisations of the current code: support
for addition as well as logical ops, and support for non-constant second
operands. These are harder to detect in the same peephole way, so the
patch tries to take a more global approach.
The idea is to get information about the minimum operation width
in two ways:
(1) by using the range information attached to the SSA_NAMEs
(effectively a forward walk, since the range info is
context-independent).
(2) by back-propagating the number of output bits required by
users of the result.
As explained in the comments, there's a balance to be struck between
narrowing an individual operation and fitting in with the surrounding
code. The approach is pretty conservative: if we could narrow an
operation to N bits without changing its semantics, it's OK to do that if:
- no operations later in the chain require more than N bits; or
- all internally-defined inputs are extended from N bits or fewer,
and at least one of them is single-use.
See the comments for the rationale.
I didn't bother adding STMT_VINFO_* wrappers for the new fields
since the code seemed more readable without.

This patch adds a concept of nested "scopes" to dumpfile.c's dump_*_loc
calls, and wires it up to the DUMP_VECT_SCOPE macro in tree-vectorizer.h,
so that the nested structure is shown in -fopt-info by indentation.
For example, this converts -fopt-info-all e.g. from:
test.c:8:3: note: === analyzing loop ===
test.c:8:3: note: === analyze_loop_nest ===
test.c:8:3: note: === vect_analyze_loop_form ===
test.c:8:3: note: === get_loop_niters ===
test.c:8:3: note: symbolic number of iterations is (unsigned int) n_9(D)
test.c:8:3: note: not vectorized: loop contains function calls or data references that cannot be analyzed
test.c:8:3: note: vectorized 0 loops in function
to:
test.c:8:3: note: === analyzing loop ===
test.c:8:3: note: === analyze_loop_nest ===
test.c:8:3: note: === vect_analyze_loop_form ===
test.c:8:3: note: === get_loop_niters ===

test.c:8:3: note: not vectorized: loop contains function calls or data references that cannot be analyzed
test.c:8:3: note: vectorized 0 loops in function
showing that the "symbolic number of iterations" message is within
the "=== analyze_loop_nest ===" (and not within the
"=== vect_analyze_loop_form ===").
This is also enabling work for followups involving optimization records
(allowing the records to directly capture the nested structure of the
dump messages).

This patch removes alt_dump_file from dumpfile.h, making it static
within dumpfile.c. This allows for changing how -fopt-info is
implemented, and potentially adding other kinds of dump target, such
as remarks or optimization records.
Doing so requires changing the implementation of dump_enabled_p, so
the patch changes this to a simple lookup of a boolean global, which
is updated any time dump_file or alt_dump_file change.
