The behaviour of the binder when handling command line arguments and exit
codes is simplified so that references to the corresponding runtime symbols
are always generated when the runtime is configured with command line
argument and exit code support. This allows Ada.Command_Line to work with
all runtimes, which was not the case previously.
As a result of this change, configurable runtimes that do not include
Ada.Command_Line and it support files, but are configured with
Command_Line_Args and/or Exit_Status_Supported set to True will need to
provide the symbols required by the binder, as these symbols will no longer
be defined in the binder generated file.

This removes the setting of the Is_Ignored_Transient flag on the temporaries
needing finalization created by Expand_Ctrl_Function_Call when invoked from
within the dependent expressions of conditional expressions.
This flag tells the general finalization machinery to disregard the object.
But temporaries needing finalization present in action lists of dependent
expressions are picked up by Process_Transients_In_Expression, which deals
with their finalization and sets the Is_Finalized_Transient flag on them.
Now this latter flag has exactly the same effect as Is_Ignored_Transient
as far as the general finalization machinery is concerned, so setting the
flag is unnecessary. In the end, the flag can be decoupled entirely from
transient objects and renamed into Is_Ignored_For_Finalization.
This also moves around the declaration of a local variable and turns a
library-level procedure into a nested procedure.

This occurs for an aggregate of a derived tagged type in the body of the

the parent type global, as is the case here.

This patch relaxes the requirement that discriminants values should be
known at compile time for a particular optimization to be applied. That
optimization is the one that treats an unconstrained object as constrained
when the object is of a limited type, in order to reduce the size of the

What makes it possible to relax this requirement is that the set of

If G1 is a generic package and G1.G2 is a child unit (also a generic package)
then it would be illegal if some third generic unit (declared outside of G1)

a- the visibility of a compiler-generated renaming is incorrect;

This streamlines the submachinery that makes it so that the finalization of
temporaries created for EWAs and conditional expressions is deferred to the
enclosing context.
The original implementation was using a deep tree traversal for EWAs, which
was later restricted to immediate subexpressions; this further flattens it
to the traversal of the immediate list of actions of the EWA in keeping with
the implementation for conditional expressions.
This should not change anything because the enclosing context found by the
machinery is the same, whatever the starting position in a nest of EWAs or
conditional expressions.

This patch fixes two issues with the handling of 128-bit TImode integer
constants in the x86_64 backend. The main issue is that GCC always
tries to load 128-bit integer constants via broadcasts to vector SSE
registers, even if the result is required in general registers. This
is seen in the two closely related functions below:
__int128 m;
void foo() { m &= CONST; }
void bar() { m = CONST; }
When compiled with -O2 -mavx, we currently generate:
foo: movabsq $81985529216486895, %rax
vmovq %rax, %xmm0
vpunpcklqdq %xmm0, %xmm0, %xmm0
vmovq %xmm0, %rax
vpextrq $1, %xmm0, %rdx
andq %rax, m(%rip)
andq %rdx, m+8(%rip)
ret
bar: movabsq $81985529216486895, %rax
vmovq %rax, %xmm1
vpunpcklqdq %xmm1, %xmm1, %xmm0
vpextrq $1, %xmm0, %rdx
vmovq %xmm0, m(%rip)
movq %rdx, m+8(%rip)
ret
With this patch we defer the decision to use vector broadcast for
TImode until we know that we actually want a SSE register result,
by moving the call to ix86_convert_const_wide_int_to_broadcast from
the RTL expansion pass, to the scalar-to-vector (STV) pass. With
this change (and a minor tweak described below) we now generate:
foo: movabsq $81985529216486895, %rax
andq %rax, m(%rip)
andq %rax, m+8(%rip)
ret
bar: movabsq $81985529216486895, %rax
vmovq %rax, %xmm0
vpunpcklqdq %xmm0, %xmm0, %xmm0
vmovdqa %xmm0, m(%rip)
ret
showing that we now correctly use vector mode broadcasts (only)
where appropriate.
The one minor tweak mentioned above is to enable the un-cprop hi/lo
optimization, that I originally contributed back in September 2004
https://gcc.gnu.org/pipermail/gcc-patches/2004-September/148756.html
even when not optimizing for size. Without this (and currently with
just -O2) the function foo above generates:
foo: movabsq $81985529216486895, %rax
movabsq $81985529216486895, %rdx
andq %rax, m(%rip)
andq %rdx, m+8(%rip)
ret
I'm not sure why (back in 2004) I thought that avoiding the implicit
"movq %rax, %rdx" instead of a second load was faster, perhaps avoiding
a dependency to allow better scheduling, but nowadays "movq %rax, %rdx"
is either eliminated by GCC's hardreg cprop pass, or special cased by
modern hardware, making the first foo preferrable, not only shorter but
also faster.

The issue mentioned in PR112525 would be able to be handled by

This change moves the lowering pass after the type determination and
the type checking passes. This lets us simplify some of the code that
determines the type of an expression, which previously had to work
correctly both before and after type determination.
I'm doing this to help with future generic support. For example, with
generics, we can see code like
func ident[T any](v T) T { return v }
func F() int32 {
s := int32(1)
return ident(s)
}
Before this change, we would type check return statements in the
lowering pass (see Return_statement::do_lower). With a generic
example like the above, that means we have to determine the type of s,
and use that to infer the type arguments passed to ident, and use that
to determine the result type of ident. That is too much to do at
lowering time. Of course we can change the way that return statements
work, but similar issues arise with index expressions, the types of
closures for function literals, and probably other cases as well.
Rather than try to deal with all those cases, we move the lowering
pass after type checking. This requires a bunch of changes, notably
for determining constant types. We have to add type checking for
various constructs that formerly disappeared in the lowering pass.
So it's a lot of shuffling. Sorry for the size of the patch.

The problem here is that in C++ structs and classes have a
linkage too so the type vertex is not considered local to
the TU but will conflict with the globally defined one
in graphds.h. The simple way to fix this is to wrap the ones
defined locally in gimple-ssa-sccopy.cc inside an anonymous namespace
and they are now considered locally to that TU.

The following improves the manual work needed to make a -gimple dump
valid input to the GIMPLE FE. First of all it recognizes the 'sizetype'
tree and dumps it as __SIZETYPE__, then it changes dumping vector types
without name from 'vector(n) T' to 'T [[gnu::vector_size(n')]]' which
we can parse in most relevant contexts (and that's shorter than
using __attribute__). Third it avoids a NULL_TREE TMR_STEP when
it would be one, an optimization that's re-done when generating RTL.

For 'wv' instructions, e.g. vwadd.wv vd,vs2,vs1.
vs2 has same EEW as vd.
vs1 has smaller than vd.
So, vs2 can overlap with vd, but vs1 can only overlap highest-number of vd
when LMUL of vs1 is greater than 1.
We already have supported overlap for vs1 LMUL >= 1.
But I forget vs1 LMUL < 1, vs2 can overlap vd even though vs1 totally can not overlap vd.

reduc_plus_int (int *__restrict a, int n)
{
int64_t r = 0;
for (int i = 0; i < n; ++i)
r += a[i];
return r;
}
When we use --param=riscv-autovec-lmul=m2, the codegen is good to us because we already supported
overlap for source EEW32 LMUL1 -> dest EEW64 LMUL2.

As written earlier, this test was written with the x86 specifics in mind

If a declare variant call can be resolved in gimple already as in the

tests like that already, the point of the test is that it is not known
during gimplification time which exact call should be chosen as it depends

The following testcase ICEs because we aren't careful enough with
alloc_size attribute. We do check that such an argument exists
(although wouldn't handle correctly functions with more than INT_MAX
arguments), but didn't check that it is scalar integer, the ICE is
trying to fold_convert a structure to sizetype.
Given that the attribute can also appear on non-prototyped functions
where the arguments aren't known, I don't see how the FE could diagnose
that and because we already handle the case where argument doesn't exist,
I think we should also verify the argument is scalar integer convertible
to sizetype. Furthermore, given this is not just in diagnostics but
used for code generation, I think it is better to punt on arguments with
larger precision then sizetype, the upper bits are then truncated.
The patch also fixes some formatting issues and avoids duplication of the
fold_convert, plus removes unnecessary check for if (arg1 >= 0), that is
always the case after if (arg1 < 0) return ...;
