So, I've spent some time on this. While wide_int is in the patch a
fixed/variable
number of limbs (aka len) storage depending on precision (precision >
WIDE_INT_MAX_PRECISION means heap allocated limb array, otherwise it is
inline), widest_int has always very large precision
(WIDEST_INT_MAX_PRECISION, currently defined to the INTEGER_CST imposed
limitation of 255 64-bit limbs) but uses inline array for length
corresponding up to WIDE_INT_MAX_PRECISION bits and for larger one uses
similarly to wide_int a heap allocated array of limbs.
These changes make both wide_int and widest_int obviously non-POD, not
trivially default constructible, nor trivially copy constructible, trivially
destructible, trivially copyable, so not a good fit for GC and some vec
operations.
One common use of wide_int in GC structures was in dwarf2out.{h,cc}; but as
large _BitInt constants don't appear in RTL, we really don't need such large
precisions there.
So, for wide_int the patch introduces rwide_int, restricted wide_int, which
acts like the old wide_int (except that it is now trivially default
constructible and has assertions precision isn't set above
WIDE_INT_MAX_PRECISION).
For widest_int, the nastiness is that because it always has huge precision
of 16320 right now,
a) we need to be told upfront in wide-int.h before calling the large
value internal functions in wide-int.cc how many elements we'll need for
the result (some reasonable upper estimate is fine)
b) various of the wide-int.cc functions were lazy and assumed precision is
small enough and often used up to that many elements, which is
undesirable; so, it now tries to decreas that and use xi.len etc. based
estimates instead if possible (sometimes only if precision is above
WIDE_INT_MAX_PRECISION)
c) with the higher precision, behavior changes for lrshift (-1, 2) etc. or
unsigned division with dividend having most significant bit set in
widest_int - while such values were considered to be above or equal to
1 << (WIDE_INT_MAX_PRECISION - 2), now they are with
WIDEST_INT_MAX_PRECISION and so much larger; but lrshift on widest_int
is I think only done in ccp and I'd strongly hope that we treat the
values as unsigned and so usually much smaller length; so it is just
when we call wi::lrshift (-1, 2) or similar that results change.
I've noticed that for wide_int or widest_int references even simple
operations like eq_p liked to allocate and immediately free huge buffers,
which was caused by wide_int doing allocation on creation with a particular
precision and e.g. get_binary_precision running into that. So, I've
duplicated that to avoid the allocations when all we need is just a
precision.
The patch below doesn't actually build anymore since the vec.h asserts
(which point to useful stuff though), so temporarily I've applied it also

hack. The two spots that trigger are tree-ssa-loop-niter.cc doing qsort on
widest_int vector (to be exact, swapping elements in the vector of
widest_int or wide_int by memcpy actually would work, the reason it has
non-trivial destructor and copy assignment/copy constructor is to make sure
distinct objects have (if needed) distinct heap allocations and that those
are freed in the end, but the bitwise memcpy swapping preserves that), and
omp_general.cc using two widest_int members in a GC structure. For some
reason, a more important problem isn't diagnosed, loop and nb_iter_bound
structs (also GC) having widest_int members (first one 2, second one just
one). And then there is e.g. another issue with slsr, which allocates
structs containing widest_int in obstack, not expecting it would need to
construct those (and where to destruct them). Also, ipa_bits contains
2 widest_int members in GC allocated structure. Actually the reason
is quite obvious, my assert has been added just for GC vec of non-trivially
destructible types, neither loop, nor ipa_bits are used in vectors. Bet
we should make wide_int_storage and widest_int_storage GTY ((user)) and
just declare but don't define the handlers or something similar.
And, now the question is what to do about this. I guess for omp_general
I could just use generic_wide_int <fixed_wide_int_storage <1024> > or
something similar, after all the widest_int wasn't really great when it
had maximum precision of WIDE_INT_MAX_PRECISION, different values on
different targets, it has very few uses and is easy to change (thinking
about this, makes me wonder what we do for offloading if offload host
has different WIDE_INT_MAX_PRECISION from offload target).
But the more important question is what to do about loop/niters analysis.
I think for number of iteration analysis it might be ok to punt somehow
(if there is a way to tell that number of iterations is unknown) if we
get some bound which is too large to be expressible in some reasonably small
fixed precision (whether it is WIDE_INT_MAX_PRECISION, or something
different is a question). We could either introduce yet another widest_int
like storage which would have still WIDEST_INT_MAX_PRECISION precision, but
would ICE if length is set to something above its fixed width. One problem
is that the write_val estimations are often just conservatively larger and
could trigger even if the value fits in the end. Or we could use
generic_wide_int <fixed_wide_int_storage <WIDE_INT_MAX_PRECISION> > (perhaps
call that rwidest_int), the drawback would be that it would be slightly harder
to use as it has different precision from widest_int, we'd need to do some
from on it or the like. Plus I really don't know the niters code to know
how to punt.
ipa_bits is even worse, because unlike niter analysis, I think it is very
much desirable to support IPA VRP of all supported _BitInt sizes. Shall
we perhaps use trailing_wide_int storage in there, or conditionally
rwidest_int vs. INTEGER_CSTs for stuff that doesn't fit, something else?
What about slsr? This is after bitint lowering, so it shouldn't be
performing opts on larger BITINT_TYPEs and so could also go with the
rwidest_int.
With the above vec.h hack the short (in number of lines, otherwise
it is large, each 16319 bit decimal constant is huge) testcase below works,
but even make check-gcc RUNTESTFLAGS=dg.exp=bitint* (i.e. the compile only
tests) show some ICEs, some of them due to widest_int in loop, others in
slsr, others to be debugged.
As for the qsort in niters, if we change niters to use some rwidest_int,
either fixed or something new, then the sorting problem could go away.
Another option would be to rename vec_detail::is_trivially_copyable_or_pair
trait to say vec_detail::is_qsort_sortable and allow code to amend that
trait on a type by type basis when needed after analysing it works correctly
for some further type (like wide_int or widest_int). But am not sure it
would work if widest-int.h is included before vec.h etc.
Your thoughts on all of this?
