In PR 113476 we have discovered that ipcp_param_lattices is no longer
a POD and should be destructed. In a follow-up discussion it
transpired that their initialization done by memsetting their backing
memory to zero is also invalid because now any write there before
construction can be considered dead. Plus that having them in an
array is a little bit old-school and does not get the extra checking
offered by vector along with automatic construction and destruction
when necessary.
So this patch converts the array to a vector. That however means that
ipcp_param_lattices cannot be just a forward declared type but must be
known to all code that deals with ipa_node_params and thus to all code
that includes ipa-prop.h. Therefore I have moved ipcp_param_lattices
and the type it depends on to a new header ipa-cp.h which now
ipa-prop.h depends on. Because we have the (IMHO not a very wise)
rule that headers don't include what they need themselves, I had to
add inclusions of ipa-cp.h and sreal.h (on which it depends) to very
many files, which made the patch rather ugly.

I went through suspicios %l in format strings of *printf family functions
combined with casts to (long) or (unsigned long) and tried to find out the
types of the original expressions that were cast.
Quite a few had size_t type, so I've used the new HOST_SIZE_T_PRINT_*
macros together with cast to fmt_size_t for those, and then there were
quite a few HOST_WIDE_INTs cast to long, used HOST_WIDE_INT_PRINT_* for
those without casts. There was one case of a weird unsigned int variable
used with %lu and (long) cast too.

GCC 5 and earlier applied array-to-pointer decay too early,
which affected the new attribute namespace code. A reduced
example of the construct that the attribute code uses is:
struct S { template<__SIZE_TYPE__ N> S(int (&)[N]); };
struct T { int a; S b; };
int a[] = { 1 };
T t = { 1, a };
This was fixed by f85e1317f8ea933f5c615680353bd646f480f7d3
(PR 16333 et al).
This patch tries to add a minimally-invasive workaround.

Currently there are four static sources of attributes:
- LANG_HOOKS_ATTRIBUTE_TABLE
- LANG_HOOKS_COMMON_ATTRIBUTE_TABLE
- LANG_HOOKS_FORMAT_ATTRIBUTE_TABLE
- TARGET_ATTRIBUTE_TABLE
All of the attributes in these tables go in the "gnu" namespace.
This means that they can use the traditional GNU __attribute__((...))
syntax and the standard [[gnu::...]] syntax.
Standard attributes are registered dynamically with a null namespace.
There are no supported attributes in other namespaces (clang, vendor
namespaces, etc.).
This patch tries to generalise things by making the namespace
part of the attribute specification.
It's usual for multiple attributes to be defined in the same namespace,
so rather than adding the namespace to each individual definition,
it seemed better to group attributes in the same namespace together.
This would also allow us to reuse the same table for clang attributes
that are written with the GNU syntax, or other similar situations
where the attribute can be accessed via multiple "spellings".
The patch therefore adds a scoped_attribute_specs that contains
a namespace and a list of attributes in that namespace.
It's still possible to have multiple scoped_attribute_specs
for the same namespace. E.g. it makes sense to keep the
C++-specific, C/C++-common, and format-related attributes in
separate tables, even though they're all GNU attributes.
Current lists of attributes are terminated by a null name.
Rather than keep that for the new structure, it seemed neater
to use an array_slice. This also makes the tables slighly more
compact.
In general, a target might want to support attributes in multiple
namespaces. Rather than have a separate hook for each possibility
(like the three langhooks above), it seemed better to make
TARGET_ATTRIBUTE_TABLE a table of tables. Specifically, it's
an array_slice of scoped_attribute_specs.
We can do the same thing for langhooks, which allows the three hooks
above to be merged into a single LANG_HOOKS_ATTRIBUTE_TABLE.
It also allows the standard attributes to be registered statically
and checked by the usual attribs.cc checks.
The patch adds a TARGET_GNU_ATTRIBUTES helper for the common case
in which a target wants a single table of gnu attributes. It can
only be used if the table is free of preprocessor directives.
There are probably other things we need to do to make vendor namespaces
work smoothly. E.g. in principle it would be good to make exclusion
sets namespace-aware. But to some extent we have that with standard
vs. gnu attributes too. This patch is just supposed to be a first step.

This, in particular, resolves LTO ICEs with big 'machine_mode's, as for RISC-V.
('mode_table' in 'lto_file_decl_data' still is 'unsigned char'; changing that
is still to be done (for use in offloading compilation), but is not trivial.)
For now, get rid of 'lto_mode_identity_table' to resolve the RISC-V LTO ICEs;
we don't need an actual table for a 1-to-1 mapping.

We extend the machine mode from 8 to 16 bits already. But there still
one placing missing from the streamer. It has one hard coded array
for the machine code like size 256.
In the lto pass, we memset the array by MAX_MACHINE_MODE count but the
value of the MAX_MACHINE_MODE will grow as more and more modes are
added. While the machine mode array in tree-streamer still leave 256 as is.
Then, when the MAX_MACHINE_MODE is greater than 256, the memset of
lto_output_init_mode_table will touch the memory out of range unexpected.
This patch would like to take the MAX_MACHINE_MODE as the size of the
array in streamer, to make sure there is no potential unexpected
memory access in future. Meanwhile, this patch also adjust some place
which has MAX_MACHINE_MODE <= 256 assumption.
Care is taken that for offload compilation, we interpret the stream-in
data in terms of the host 'MAX_MACHINE_MODE' ('file_data->mode_bits'),
which very likely is different from the offload device
'MAX_MACHINE_MODE'.

Without LTO, TYPE_POINTER_TO/TYPE_REFERENCE_TO chains are only maintained
inside of build_{pointer,reference}_type_for_mode and those routines
ensure that the pointer/reference type added to the chain is really
without any user attributes (unless something would modify the types
in place, but that would be wrong).
Now, LTO adds stuff to these chains in lto_fixup_prevailing_type but
doesn't guarantee that. The testcase in the PR (which I'm not including
for testsuite because when (I hope) the aarch64 backend bug will be fixed,
the testcase would work either way) shows a case where user has
TYPE_USER_ALIGN type with very high alignment, as there aren't enough
pointers to float in the code left that one becomes the prevailing one
(because types with attributes are created with build_distinct_type_copy
and thus their own TYPE_MAIN_VARIANTs), lto_fixup_prevailing_type puts
it into the TYPE_POINTER_TO chain of float and later on during expansion
of __builtin_cexpif expander uses build_pointer_type (float_type_node)
to emit a sincosf call and instead of getting a normal pointer type gets
this non-standard one.
The following patch fixes that by not adding into those chains
types with TYPE_ATTRIBUTES, and for REFERENCE_TYPEs not even with
TYPE_REF_IS_RVALUE - while the C++ FE adds those into those chains,
it always ensures such a type goes immediately after the corresponding
non-TYPE_REF_IS_RVALUE REFERENCE_TYPE with the same
mode/TYPE_REF_CAN_ALIAS_ALL, so LTO would need to ensure that too, but
TYPE_REF_IS_RVALUE types are looked that way only in the C++ FE.

LTO partitioning does renaming of symbols that ends up in same partition
and clash with assembler name. This is done for "ordinary" symbols (such
as static functions) but also for symbols that are kept only as master
clones holding bodies of functions to be specialized later.
This is done only becuase we stream bodies to named section and clash
in names would mean that ltrans will load wrong body and crash.
Martin recently added bit to stream body for clones that are needed
since this makes it easier to bookeep what summaries are output. THis
however triggers mass renaming of inline clones that is very slow
and unnecesary since their bodies are never streamed.

* lto-partition.cc (may_need_named_section_p): Clones with no body
need no remaning.

When adding a catch-all partition, we map NULL to it. That mapping is
ineffective and unnecessary. Drop it.

mapping.

Update documentation of -fwhole-program which was wrongly
claiming that it is useless with LTO whole it is useful for LTO without plugin
and extends -fwhole-program to also work with incremental linking.
This is useful when building kernel where the incremental link is de-facto fina
binary and only some explicitly marked symbols needs to remain.
