[Ada] Compiler may blow up on array aggregates whose size is very large
The compiler may crash when compiling array aggregates where the
computation of the size produces a very large number that overflows
(possibly producing a small result), such as with an aggregate of a type
that is an array of arrays, where each array range has close to
Integer'Last elements. That can lead to Aggr_Size_OK returning
incorrectly returning True, following on to allocating a very large
array in function Flatten that blows the stack. The size computation
was being performed using type Int, so this was changed to use universal
arithmetic.

[Ada] Eliminate redundant range checks on conversions
This gets rid of redundant range checks generated in 5 out of the 9
cases of scalar conversions, i.e. (integer, fixed-point, floating-point)
converted to (integer, fixed-point, floating-point).
The problem is that the Real_Range_Check routine rewrites the conversion
node into a conversion to the base type so, when its parent node is
analyzed, a new conversion to the subtype may be introduced, depending
on the context, giving rise to a second range check against the subtype
bounds.
This change makes Real_Range_Check rewrite the expression of the
conversion node instead of the node, so that the type of the node is
preserved and no new conversion is introduced. As a matter of fact,
this is exactly what happens in the float-to-float case which goes to
the Generate_Range_Check circuit instead and does not suffer from the
duplication of range checks.
For the following procedure, the compiler must now generate exactly one
range check per nested function:
procedure P is
type I1 is new Integer range -100 .. 100;
type I2 is new Integer range -200 .. 200;
type D1 is delta 0.5 range -100.0 .. 100.0;
type D2 is delta 0.5 range -200.0 .. 200.0;
type F1 is new Long_Float range -100.0 .. 100.0;
type F2 is new Long_Float range -200.0 .. 200.0;
function Conv (A : I2) return I1 is
begin
return I1 (A);
end;
function Conv (A : D2) return I1 is

return I1 (A);
end;

does not necessarily point to the node that was just rewritten, but to

This change prevents the analysis phase of the front-end from setting
the Do_Range_Check flag in the very peculiar case of the source of a

This pattern appears in the ancient DEC Starlet package and it doesn't

The codegen pass would subsequently generate the following invalid code
(int)(double) a = (int)((double) a + 1.0) + 1
The LHS expression `(int)(double) a', represented as a FIX_TRUNC_EXPR

[arm] Recognize thumb2 16-bit variants of the add and compare instructions
The addsi3_compare_op[12] patterns currently only have constraints to
pick the 32-bit variants of the instructions. Although the assembler
may sometimes opportunistically match a 16-bit t2 instruction, there's
no real control over that within the compiler. Consequently we might
emit a 32-bit adds instruction with a 16-bit subs instruction would
serve equally well. We do, of course still have to be careful about
the small number of boundary cases by controlling the order quite
carefully.
This patch adds the constraints and templates to match the t2 16-bit
variants of these instructions. Now, for example, we can generate
subs r0, r0, #1 // 16-bit instruction
instead of
adds r0, r0, #1 // 32-bit instruction.

skip Cholesky decomposition in is>>n_mv_dist
normal_mv_distribution maintains the variance-covariance matrix param
in Cholesky-decomposed form. Existing param_type constructors, when
taking a full or lower-triangle varcov matrix, perform Cholesky
decomposition to convert it to the internal representation. This
internal representation is visible both in the varcov() result, and in
the streamed-out representation of a normal_mv_distribution object.
The problem is that when that representation is streamed back in, the
read-back decomposed varcov matrix is used as a lower-triangle
non-decomposed varcov matrix, and it undergoes Cholesky decomposition
again. So, each cycle of stream-out/stream-in changes the varcov
matrix to its "square root", instead of restoring the original
params.
This patch includes Corentin's changes that introduce verification in
testsuite/ext/random/normal_mv_distribution/operators/serialize.cc and
other similar tests that the object read back in compares equal to the
written-out object: the modified tests pass only if (u == v).

alternate private constructor for param_type, used only by operator>>.

use rand instead of random
rand is in ISO C, whereas random is only in POSIX, so it makes sense
to use the more portable function everywhere instead of falling back
from one to the other on systems that miss the less portable one.

[C] Fix bogus nested enum error message
For:
enum a { A };
enum a { B };
we emit a bogus error about nested definitions before the real error:
foo.c:2:6: error: nested redefinition of ‘enum a’
2 | enum a { B };
| ^
foo.c:2:6: error: redeclaration of ‘enum a’
foo.c:1:6: note: originally defined here
1 | enum a { A };
| ^
This is because we weren't clearing C_TYPE_BEING_DEFINED once the
definition was over.
I think it's OK to clear C_TYPE_BEING_DEFINED even for a definition
that actually is nested (and so whose outer definition is still open),
since we'll already have given an error by then. It means that second
and subsequent attempts to define a nested enum will usually get the
redeclaration error instead of the nested error, but that seems just
as accurate (nested_first and nested_second in the test). The only
exception is if the first nested enum was also invalid by being empty,
but then the enum as a whole has already produced two errors
(nested_empty in the test).
