The range infrastructure has code to decompose POLY_INT_CST ranges
to worst-case integer bounds. However, it had the fundamental flaw
(obvious in hindsight) that it applied to anti-ranges too, meaning
that a range 2+2X would end up with a range of ~[2, +INF], i.e.
[-INF, 1]. This patch decays to varying in that case instead.
I'm still a bit uneasy about this. ISTM that in terms of
generality:
SSA_NAME => POLY_INT_CST => INTEGER_CST
=> ADDR_EXPR
I.e. an SSA_NAME could store a POLY_INT_CST and a POLY_INT_CST
could store an INTEGER_CST (before canonicalisation). POLY_INT_CST
is also “as constant as” ADDR_EXPR (well, OK, only some ADDR_EXPRs
are run-time rather than link-time constants, whereas all POLY_INT_CSTs
are, but still). So it seems like we should at least be able to treat
POLY_INT_CST as symbolic. On the other hand, I don't have any examples
in which that would be useful.

C2X adds BOOL_MAX and BOOL_WIDTH macros to <limits.h>. As GCC only
supports values 0 and 1 for _Bool (regardless of the number of bits in
the representation, other bits are padding bits and if any of them are
nonzero, the representation is a trap representation), the values of
those macros can just be hardcoded directly in <limits.h> rather than
needing corresponding predefined macros.
Bootstrapped with no regressions on x86_64-pc-linux-gnu.

Currently if requires_stack_frame_p() returns true for some insn, the

In some cases, expand_expr_real_2 prefers to use the mode of the
caller-suggested target instead of the mode of the expression when
passing values to reduce_to_bit_field_precision. E.g.:
else if (target == 0)
op0 = convert_to_mode (mode, op0,
TYPE_UNSIGNED (TREE_TYPE
(treeop0)));
else
{
convert_move (target, op0,
TYPE_UNSIGNED (TREE_TYPE (treeop0)));
op0 = target;
}
where “op0” might not have “mode” for the “else” branch,
but does for all the others.
reduce_to_bit_field_precision discards the suggested target if it
has the wrong mode. This patch moves that to expand_expr_real_2
instead (conditional on reduce_bit_field).
gcc/
PR middle-end/96151
* expr.c (expand_expr_real_2): When reducing bit fields,

This is an arm version of aarch64 patch r11-1741. The approach
is essentially identical, not much more than s/aarch64/arm/.
To recap, PR95726 is about template look-up for things like:
foo<float vecf __attribute__((vector_size(16)))>
foo<float32x4_t>
The immediate cause of the problem is that the hash function usually
returns different hashes for these types, yet the equality function
thinks they are equal. This then raises the question of how the types
are supposed to be treated.
The answer we chose for AArch64 was that the GNU vector type should
be treated as distinct from float32x4_t, but that each type should
implicitly convert to the other.
This would mean that, as far as the PR is concerned, the hashing
function is right to (sometimes) treat the types differently and
the equality function is wrong to treat them as the same.
The most obvious way to enforce the type difference is to use a
target-specific type attribute. That on its own is enough to fix
the PR. The difficulty is deciding whether the knock-on effects
are acceptable.
One obvious effect is that GCC then rejects:
typedef float vecf __attribute__((vector_size(16)));
vecf x;
float32x4_t &z = x;
on the basis that the types are no longer reference-compatible.
For AArch64 we took the approach that this was the correct behaviour.
It is also consistent with current Clang.
A trickier question is whether:
vecf x;
float32x4_t y;
… c ? x : y …
should be valid, and if so, what its type should be [PR92789].
As explained in the comment in the testcase, GCC and Clang both
accepted this, but GCC chose the “then” type while Clang chose
the “else” type. This can lead to different mangling for (probably
artificial) corner cases, as seen for “sel1” and “sel2” in the
testcase.
Adding the attribute makes GCC reject the conditional expression
as ambiguous. For AArch64 we took the approach that this too is
the correct behaviour, for the reasons described in the testcase.
However, it does seem to have the potential to break existing code.
