can_duplicate_and_interleave_p checks whether we know a way of
building a particular VLA SLP invariant. g:60034ecf25597bd515f
skipped that test for booleans, to support MASK_LEN_GATHER_LOAD
calls with a dummy all-ones mask. But there's nothing fundamentally
different about VLA masks vs VLA data vectors. If we have a VLA mask
that isn't all-ones, we need some way of loading it. This ultimately
led to the ICE in the PR.
This patch fixes it by applying can_duplicate_and_interleave_p
to masks, while also adding a special path for uniform vectors
(of all kinds) to support the MASK_LEN_GATHER_LOAD usage. This
also fixes an XFAIL in pr36648.cc for SVE.
The patch is mostly Richard's. My only changes were to skip
redundant conversions and to use gimple_build_vector_from_val
for all eligible vectors.

Currently for an unsigned 16-bit comparison between memory and an
immediate where the high bit is set, a clc is emitted. This is because
the constant is created for mode HI and therefore sign extended. This
means constraint D does not hold anymore. Since the mode already
restricts the immediate to 16 bit, it is enough to make use of
constraint n and chop of the high bits in the output template.

in config.gcc, but mips*-sde-elf* is the only target which overwrites
tm_defines shell variable rather than just appending to it (or in one case
prepending), all other targets append something to it, including other
mips* triplets.
I believe (just from looking at config.gcc) that the difference is that
LIBC_GLIBC=1 LIBC_UCLIBC=2 LIBC_BIONIC=3 LIBC_MUSL=4 HEAP_TRAMPOLINES_INIT=0
isn't defined without the patch and is with the patch.

Come back to review the codes of gather/scatter, notice gather_scatter_valid_offset_mode_p looks odd.
gather_scatter_valid_offset_mode_p is supposed to block vluxei64/vsuxei64 in RV32 system.
However, it failed to do that since it is passing data_mode instead of index mode:
riscv_vector::gather_scatter_valid_offset_mode_p (<RATIO2:MODE>mode)
It should be RATIO2I instead of RATIO2.
So we have this following iterators which already can block the this situation:
(define_mode_iterator RATIO8I [
RVVM1QI
RVVM2HI
RVVM4SI
(RVVM8DI "TARGET_VECTOR_ELEN_64 && TARGET_64BIT")
])
We can see TARGET_64BIT to block EEW64 index mode on RV32 system.
So, gather_scatter_valid_offset_mode_p is no longer needed.
After remove it, I find due to incorrect gather_scatter_valid_offset_mode_p.
We failed to vectorize such case in RV32 in the past:
void __attribute__ ((noinline, noclone)) \
f_##DATA_TYPE (DATA_TYPE *restrict dest, DATA_TYPE *restrict src, \
INDEX##BITS *restrict indices, INDEX##BITS *restrict cond) \
{ \
for (int i = 0; i < 128; ++i) \
if (cond[i]) \
dest[i] += src[indices[i]]; \
}
T (int64_t, 8)

https://godbolt.org/z/T3ara3fM3
Checked compiler explorer, we can see GCC failed to vectorize it but Clang can vectorize it.
So adapt the tests checking vectorization cases from 8 -> 11.
Confirm we have same behavior as Clang now.

Since r14-2893, the frontend parser object needs to exist when running in
preprocess-only mode, because pragma_lex() is now called in that mode and
needs to make use of it. This is handled by calling c_init_preprocess() at
startup. If -fpch-preprocess is in effect (commonly, because of
-save-temps), a PCH file may be loaded during preprocessing, in which
case the parser will be destroyed, causing the issue noted in the
PR. Resolve it by reinitializing the frontend parser after loading the PCH.

PR109849 shows that a loop that heavily pushes and pops from a stack
implemented by a C++ std::vec results in slow code, mainly because the
vector structure is not split by SRA and so we end up in many loads
and stores into it. This is because it is passed by reference
to (re)allocation methods and so needs to live in memory, even though
it does not escape from them and so we could SRA it if we
re-constructed it before the call and then separated it to distinct
replacements afterwards.
This patch does exactly that, first relaxing the selection of
candidates to also include those which are addressable but do not
escape and then adding code to deal with the calls. The
micro-benchmark that is also the (scan-dump) testcase in this patch
runs twice as fast with it than with current trunk. Honza measured
its effect on the libjxl benchmark and it almost closes the
performance gap between Clang and GCC while not requiring excessive
inlining and thus code growth.
The patch disallows creation of replacements for such aggregates which
are also accessed with a precision smaller than their size because I
have observed that this led to excessive zero-extending of data
leading to slow-downs of perlbench (on some CPUs). Apart from this
case I have not noticed any regressions, at least not so far.
Gimple call argument flags can tell if an argument is unused (and then
we do not need to generate any statements for it) or if it is not
written to and then we do not need to generate statements loading
replacements from the original aggregate after the call statement.
Unfortunately, we cannot symmetrically use flags that an aggregate is
not read because to avoid re-constructing the aggregate before the
call because flags don't tell which what parts of aggregates were not
written to, so we load all replacements, and so all need to have the
correct value before the call.
This version of the patch also takes care to avoid attempts to modify
abnormal edges, something which was missing in the previosu version.

gcc/ChangeLog:
* config/i386/i386.cc (ix86_expand_split_stack_prologue): Load
function address to a register for ix86_cmodel == CM_LARGE.
gcc/testsuite/ChangeLog:
* gcc.target/i386/pr112686.c: New test.
The new warning has two purposes: First, it makes clearer to the
user that it is about OpenMP and, secondly and more importantly,
it permits to use -Wno-openmp.
The newly added -Wopenmp is enabled by default and replaces the
'0' (always warning) in several OpenMP-related warning calls.
For code shared with OpenACC, it only uses OPT_Wopenmp for
'flag_openmp | flag_openmp_simd'.
gcc/c-family/ChangeLog:
* c.opt (Wopenmp): Add, enable by default.
