Hi,
I have noticed that in gcc-13, test05 (in the 94749.cc testcase) is still
enabled for simulators, and I have noticed that because of test05, the

our simulator for armv8.1-m.main+mve, even after 3 hours.

Hi all,
it turned out that 'declare target' with 'link' clause was broken in multiple
ways.
The main fix is the attached patch, i.e. namely pushing the variables already to
the offload-vars list already in the FE.
When implementing it, I noticed:
* C has a similar issue when using nested funct
This patch adds
--param=vrp-block-limit=N
When the basic block counter for a function exceeded 'N' , VRP is
invoked with the new fast_vrp algorithm instead. This algorithm uses a
lot less memory and processing power, although it does get a few less
things.
Primary motivation is cases
This patch changes the algorithm for fast VRP. When looking at PR
114855, although VRP is not the main culrpit, it is taking about 600
seconds out of the 10,000.. far more than it should. That test case has
about 400,000 basic blocks, and when we get into that size, some of the
tables and such
I found that I was frequently writing the same hunk of code which checks
the result of set_range_info() and and prints the global range to the
dump_file when it is updated.
This routine only returns true if the value provided improves the
range. Ie, 'old_value' intersect 'new_value' != '
With the earlier rework of VRP which removed the array_bounds pass, it
is now possible to invoke a different VRP for any pass. This patch adds
the ability to call fast_vrp with the final_pass flag set, and remove
invoke the remove_unreachable object to remove __builtin_unreachable

in the parsing of gnu::base64 #embed parameter and emits it as well
in -E -fdirectives-only preprocessing, e.g.

For outer loop vectorization of a data reference in the inner loop
we have to look at both steps to see if they preserve alignment.
What is special for this testcase is that the outer loop step is
one element but the inner loop step four and that we now use SLP
and the vectorization factor is one.
LGTM, thanks :)

This fixes a warning from one of the test allocators:
warning: base class 'class std::allocator<__gnu_test::copy_tracker>' should be
explicitly initialized in the copy constructor [-Wextra]

We set DECL_BIT_FIELD optimistically during the translation of record types

When a non-overridable aspect is explicitly specified for a

The processing of primitive operations is now always uniform for tagged and

This implements modulo reduction for nonbinary modular multiplication with
