libstdc++: Install <coroutine> header for freestanding [PR103726]
The standard says that <coroutine> should be present for freestanding.
That was intentionally left out of the initial implementation, but can
be done without much trouble. The header should be moved to libsupc++ at
some point in stage 1.
The standard also says that <coroutine> defines a std::hash
specialization, which was missing from our implementation. That's a
problem for freestanding (see LWG 3653) so only do that for hosted.
We can use concepts to constrain the __coroutine_traits_impl base class
when compiled with concepts enabled. In a pure C++20 implementation we
would not need that base class at all and could just use a constrained
partial specialization of coroutine_traits. But the absence of the
__coroutine_traits_impl<R, void> base would create an ABI difference
between the non-standard C++14/C++17 support for coroutines and the same
code compiled as C++20. If we drop support for <coroutine> pre-C++20 we
should revisit this.

libstdc++: Optimize std::ostream inserters for single characters
On the libsdc++ mailing list Lewis Hyatt pointed out the performance
overhead of using sputn in stream inserters, rather than writing
directly to the streambuf's put area:
https://gcc.gnu.org/pipermail/libstdc++/2021-July/052877.html
As Lewis noted, the standard explicitly requires a call to sputn for
inserting a std::basic_string_view or std::basic_string. But for
inserting single characters or null-terminated strings it is more vague,
and so we can improve performance by not using the __ostream_insert
function.
This is a minimal change that avoids __ostream_insert for single
characters. We can use the unformatted basic_ostream::put(charT)
function when we don't need the additional effects of a formatted output
function (i.e. padding and resetting the width). The put function will
insert into the buffer if possible, and only make a virtual call (to
overflow) if the buffer is full.
We could also avoid sputn when inserting null-terminated character
strings, but that would require using a new function for inserting
null-terminated strings, so the existing code using sputn is still used
for basic_string and basic_string_view. My preference is to leave that
for now, and try to improve the standard. We could either remove the
requirement to call sputn, or allow sputn to write directly to the
buffer instead of calling xsputn.

* include/std/ostream (operator<<(basic_ostream&, charT)):
Use unformatted input if no padding is needed.

Recognize MULT_HIGHPART_EXPR in tree-ssa-math-opts pass.
This is the third iteration of a patch to perceive MULT_HIGHPART_EXPR
in the middle-end. As they say "the third time's a charm". The first
version implemented this in match.pd, which was considered too early.
https://gcc.gnu.org/pipermail/gcc-patches/2020-August/551316.html
The second version attempted to do this during RTL expansion, and was
considered to be too late in the middle-end.
https://gcc.gnu.org/pipermail/gcc-patches/2021-August/576922.html
https://gcc.gnu.org/pipermail/gcc-patches/2021-August/576923.html
This latest version incorporates Richard Biener's feedback/suggestion
to perceive MULT_HIGHPART_EXPR in one of the "instruction selection
passes", specifically tree-ssa-math-opts, where the recognition of
highpart multiplications takes place in the same pass as widening
multiplications.
With each rewrite, the patch is also getting more aggressive in the
set of widening multiplications that it recognizes as highpart multiplies.
Currently any widening multiplication followed by a right shift (either
signed or unsigned) by a bit count sufficient to eliminate the lowpart
is recognized. The result of this shift doesn't need to be truncated.
As previously, this patch confirms the target provides a suitable
optab before introducing the MULT_HIGHPART_EXPR. This is the reason
the testcase is restricted to x86_64, as this pass doesn't do anything
on some platforms, but x86_64 should be sufficient to confirm that the
pass is working/continues to work.

c++: Ensure some more that immediate functions aren't gimplified [PR103912]
Immediate functions should never be emitted into assembly, the FE doesn't
genericize them and does various things to ensure they aren't gimplified.
But the following testcase ICEs anyway due to that, because the consteval
function returns a lambda, and operator() of the lambda has
decl_function_context of the consteval function. cgraphunit.c then
does:
/* Preserve a functions function context node. It will
later be needed to output debug info. */
if (tree fn = decl_function_context (decl))
{
cgraph_node *origin_node = cgraph_node::get_create (fn);
enqueue_node (origin_node);
}
which enqueues the immediate function and then tries to gimplify it,
which results in ICE because it hasn't been genericized.
When I try similar testcase with constexpr instead of consteval and
static constinit auto instead of auto in main, what happens is that
the functions are gimplified, later ipa.c discovers they aren't reachable
and sets body_removed to true for them (and clears other flags) and we end
up with a debug info which has the foo and bar functions without
DW_AT_low_pc and other code specific attributes, just stuff from its BLOCK
structure and in there the lambda with DW_AT_low_pc etc.
The following patch attempts to emulate that behavior early, so that cgraph
doesn't try to gimplify those and pretends they were already gimplified
and found unused and optimized away.

x86_64: Ignore zero width bitfields in ABI and issue -Wpsabi warning about C zero width bitfield ABI changes [PR102024]
For zero-width bitfields current GCC classify_argument does:
if (DECL_BIT_FIELD (field))
{
for (i = (int_bit_position (field)
+ (bit_offset % 64)) / 8 / 8;
i < ((int_bit_position (field) + (bit_offset % 64))

= merge_classes (X86_64_INTEGER_CLASS, classes[i]);
}
which I think means that if the zero-width bitfields are at bit-positions
(in the toplevel aggregate) which are multiples of 64 bits doesn't do
anything, (int_bit_position (field) + (bit_offset % 64)) / 64 and
(int_bit_position (field) + (bit_offset % 64) + 63) / 64 should be equal.
But for zero-width bitfields at other bit positions it will call
merge_classes once. Now, the typical case is that the zero width bitfield
is surrounded by some bitfields and in that case, it doesn't change
anything, but it can be sandwitched in between floats too as the testcases
show.
In C we had this behavior, in C++ previously the FE was removing the
zero-width bitfields and therefore they were ignored.
LLVM and ICC seems to ignore those bitfields both in C and C++ (== passing
struct S in SSE register rather than in GPR).
The x86-64 psABI has been recently clarified by

ira: Handle "soft" conflicts between cap and non-cap allocnos
This patch looks for allocno conflicts of the following form:
- One allocno (X) is a cap allocno for some non-cap allocno X2.
- X2 belongs to some loop L2.
- The other allocno (Y) is a non-cap allocno.
- Y is an ancestor of some allocno Y2 in L2.
- Y2 is not referenced in L2 (that is, ALLOCNO_NREFS (Y2) == 0).
- Y can use a different allocation from Y2.
In this case, Y's register is live across L2 but is not used within it,
whereas X's register is used only within L2. The conflict is therefore
only "soft", in that it can easily be avoided by spilling Y2 inside L2
without affecting any insn references.
In principle we could do this for ALLOCNO_NREFS (Y2) != 0 too, with the
callers then taking Y2's ALLOCNO_MEMORY_COST into account. There would
then be no "cliff edge" between a Y2 that has no references and a Y2 that
has (say) a single cold reference.
However, doing that isn't necessary for the PR and seems to give
variable results in practice. (fotonik3d_r improves slightly but
namd_r regresses slightly.) It therefore seemed better to start
with the higher-value zero-reference case and see how things go.
On top of the previous patches in the series, this fixes the exchange2
regression seen in GCC 11.

ira: Try to avoid propagating conflicts
Suppose that:
- an inner loop L contains an allocno A
- L clobbers hard register R while A is live
- A's parent allocno is AP
Previously, propagate_allocno_info would propagate conflict sets up the
loop tree, so that the conflict between A and R would become a conflict
between AP and R (and so on for ancestors of AP).
However, when IRA treats loops as separate allocation regions, it can
decide on a loop-by-loop basis whether to allocate a register or spill
to memory. Conflicts in inner loops therefore don't need to become
hard conflicts in parent loops. Instead we can record that using the
“conflicting” registers for the parent allocnos has a higher cost.
In the example above, this higher cost is the sum of:
- the cost of saving R on entry to L
- the cost of keeping the pseudo register in memory throughout L
- the cost of reloading R on exit from L
This value is also a cap on the hard register cost that A can contribute
to AP in general (not just for conflicts). Whatever allocation we pick
for AP, there is always the option of spilling that register to memory
throughout L, so the cost to A of allocating a register to AP can't be
more than the cost of spilling A.
To take an extreme example: if allocating a register R2 to A is more
expensive than spilling A to memory, ALLOCNO_HARD_REG_COSTS (A)[R2]
could be (say) 2 times greater than ALLOCNO_MEMORY_COST (A) or 100
times greater than ALLOCNO_MEMORY_COST (A). But this scale factor
doesn't matter to AP. All that matters is that R2 is more expensive
than memory for A, so that allocating R2 to AP should be costed as
spilling A to memory (again assuming that A and AP are in different
allocation regions). Propagating a factor of 100 would distort the
register costs for AP.
move_spill_restore tries to undo the propagation done by
propagate_allocno_info, so we need some extra processing there.

at the end performs various finalizations, like applying %p so that it
works for both %I %p and %p %I orders, or applying century so that both
%C %y and %y %C works, or computation of missing fields from others

As the finalization is quite large and doesn't need to be a template
(doesn't depend on any iterators or char types), I've put it into libstdc++,
and left some padding in the state struct, so that perhaps in the future we
can track some more state without changing ABI.
Unfortunately, there is an ugly problem that the standard mandates that
get method calls the do_get virtual method and I don't see how we can
cary on any state in between those calls (even if we did an ABI change
for the facets, the methods are const, so that I think multiple threads
could use the same time_get objects and we couldn't store state in there).
There is a hack for that for GCC (seems to work with ICC too, doesn't work
with clang++) if the do_get method isn't overriden we can pass the state
around.
For both do_get_year and per IRC discussions also for %y, the behavior is

--with-avrlibc builds, with this change they are also skipped when using
--without-headers. It would be nice if using --disable-hosted-libstdcxx
automatically skipped those checks, but GLIBCXX_ENABLE_HOSTED comes too
late to make the AM_PROG_LIBTOOL checks depend on $is_hosted.
The checks for EOF, SEEK_CUR etc. cause the build to fail if there is no
<stdio.h> available. Unlike most headers, which get a HAVE_FOO_H macro,
<stdio.h> is in autoconf's default includes, so every check tries to
include it unconditionally. This change skips those checks for
freestanding builds.
Similarly, the checks for <stdint.h> types done by GCC_HEADER_STDINT try
to include <stdio.h> and fail for --without-headers builds. This change
skips the use of GCC_HEADER_STDINT for freestanding. We can probably
stop using GCC_HEADER_STDINT entirely, since only one file uses the
gstdint.h header that is generated, and that could easily be changed to
use <stdint.h> instead. That can wait for stage 1.
We also need to skip the GLIBCXX_CROSSCONFIG stage if --without-headers
was used, since we don't have any of the functions it deals with.
The end result of the changes above is that it should not be necessary
for a --disable-hosted-libstdcxx --without-headers build to also use
--with-newlib.
Finally, compile libsupc++ with -ffreestanding when --without-headers is
used, so that <stdint.h> will use <gcc-stdint.h> instead of expecting it
to come from libc.

libstdc++: Add -nostdinc++ for c++17 sources [PR100017]
When building a build!=host compiler, the just-built gcc can't be used
to build the target libstdc++ (because it is built for the host triplet,
not the build triplet). The top-level configure.ac sets up the build
flags for libstdc++ (and other "raw_cxx" libs) like this:
GCC_TARGET_TOOL(c++ for libstdc++, RAW_CXX_FOR_TARGET, CXX,
[gcc/xgcc -shared-libgcc -B$$r/$(HOST_SUBDIR)/gcc -nostdinc++ -L$$r/$(TARGET_SUBDIR)/libstdc++-v3/src -L$$r/$(TARGET_SUBDIR)/libstdc++-v3/src/.libs -L$$r/$(TARGET_SUBDIR)/libstdc++-v3/libsupc++/.libs],
c++)
The -nostdinc++ flag is only used for the IN-TREE-TOOL, i.e. when using
the just-built gcc/xgcc compiler. This means that the cross-compiler
used to build libstdc++ will add its own libstdc++ headers to the
include path. That results in the #include <cfenv> in
src/c++17/floating_to_chars.cc and src/c++17/floating_from_chars.cc
doing #include_next <fenv.h> and finding the libstdc++ fenv.h wrapper
from the host compiler. Because that has the same include guard as the
<fenv.h> in the libstdc++ we're trying to build, we never reach the
underlying <fenv.h> from libc. That results in several errors of the
form:
error: 'fenv_t' has not been declared in '::'
The most correct fix would be to add -nostdinc++ to the
RAW_CXX_FOR_TARGET variable in configure.ac, or the
RAW_CXX_TARGET_EXPORTS variable in Makefile.tpl.
Another solution would be to make the libstdc++ <fenv.h> wrapper use
_GLIBCXX_INCLUDE_NEXT_C_HEADERS like our <stdlib.h> and other C header
wrappers.
For now though, the simplest and safest solution is to just add
-nostdinc++ to the CXXFLAGS used for src/c++17/*.cc, which is what this
does.

x86_64: Improve (interunit) moves from TImode to V1TImode.
This patch improves the code generated when moving a 128-bit value
in TImode, represented by two 64-bit registers, to V1TImode, which
is a single SSE register.
Currently, the simple move:
typedef unsigned __int128 uv1ti __attribute__ ((__vector_size__ (16)));
uv1ti foo(__int128 x) { return (uv1ti)x; }
is always transferred via memory, as:
foo: movq %rdi, -24(%rsp)
movq %rsi, -16(%rsp)
movdqa -24(%rsp), %xmm0
ret
with this patch, we now generate (with -msse2):
foo: movq %rdi, %xmm1
movq %rsi, %xmm2
punpcklqdq %xmm2, %xmm1
movdqa %xmm1, %xmm0
ret
and with -mavx2:
foo: vmovq %rdi, %xmm1
vpinsrq $1, %rsi, %xmm1, %xmm0
ret
Even more dramatic is the improvement of zero extended transfers.
uv1ti bar(unsigned char c) { return (uv1ti)(__int128)c; }
Previously generated:
bar: movq $0, -16(%rsp)
movzbl %dil, %eax
movq %rax, -24(%rsp)
vmovdqa -24(%rsp), %xmm0
ret
Now generates:
bar: movzbl %dil, %edi
movq %rdi, %xmm0
ret
My first attempt at this functionality attempted to use a simple
define_split, but unfortunately, this triggers very late during the
compilation preventing some of the simplifications we'd like (in
combine). For example the foo case above becomes:
foo: movq %rsi, -16(%rsp)
movq %rdi, %xmm0
movhps -16(%rsp), %xmm0
transferring half directly, and the other half via memory.
And for the bar case above, GCC fails to appreciate that
movq/vmovq clears the high bits, resulting in:
bar: movzbl %dil, %eax
xorl %edx, %edx
vmovq %rax, %xmm1
vpinsrq $1, %rdx, %xmm1, %xmm0
ret
Hence the solution (i.e. this patch) is to add a special case
to ix86_expand_vector_move for TImode to V1TImode transfers.

c++, match.pd: Evaluate in constant evaluation comparisons like &var1 + 12 == &var2 + 24 [PR89074]
The match.pd address_comparison simplification can only handle
ADDR_EXPR comparisons possibly converted to some other type (I wonder
if we shouldn't restrict it in address_compare to casts to pointer
types or pointer-sized integer types, I think we shouldn't optimize
(short) (&var) == (short) (&var2) because we really don't know whether
it will be true or false). On GIMPLE, most of pointer to pointer
casts are useless and optimized away and further we have in
gimple_fold_stmt_to_constant_1 an optimization that folds
&something p+ const_int
into
&MEM_REF[..., off]
On GENERIC, we don't do that and e.g. for constant evaluation it
could be pretty harmful if e.g. such pointers are dereferenced, because
it can lose what exact field it was starting with etc., all it knows
is the base and offset, type and alias set.
Instead of teaching the match.pd address_compare about 3 extra variants
where one or both compared operands are pointer_plus, this patch attempts
to fold operands of comparisons similarly to gimple_fold_stmt_to_constant_1
before calling fold_binary on it.
There is another thing though, while we do have (x p+ y) p+ z to
x p+ (y + z) simplification which works on GIMPLE well because of the
useless pointer conversions, on GENERIC we can have pointer casts in between
and at that point we can end up with large expressions like
((type3) (((type2) ((type1) (&var + 2) + 2) + 2) + 2))
etc. Pointer-plus doesn't really care what exact pointer type it has as
long as it is a pointer, so the following match.pd simplification for
GENERIC only (it is useless for GIMPLE) also moves the cast so that nested
p+ can be simplified.
Note, I've noticed we don't really diagnose going out of bounds with
pointer_plus (unlike e.g. with ARRAY_REF) during constant evaluation, I
think another patch for cxx_eval_binary_expression with POINTER_PLUS will be
needed. But it isn't clear to me what exactly it should do in case of
subobjects. If we start with address of a whole var, (&var), I guess we
should diagnose if the pointer_plus gets before start of the var (i.e.
"negative") or 1 byte past the end of the var, but what if we start with
&var.field or &var.field[3] ? For &var.field, shall we diagnose out of
bounds of field (except perhaps flexible members?) or the whole var?
For ARRAY_REFs, I assume we must at least strip all the outer ARRAY_REFs
and so start with &var.field too, right?
