Is it because # libsanitizer not supported rv32, but it will break the

Arm 32, x86 (32) and mips has support for Asan[1], so we can
`reference` how they implement that,
but I guess the problem is we need someone to do that.

This patch implements the constant folding optimization(s) described in

So that move_sese_region_to_fn works properly, OpenMP/OpenACC constructs

This simple patch avoids the ICE described in the PR:
internal compiler error: in simd_valid_immediate, at config/arm/arm.cc:12866
with an early exit from simd_valid_immediate if we are trying to
handle a vector of booleans and MVE is not enabled.

The following aligns ISEL VEC_COND_EXPR expansion using VCOND
with the optab query done by vector lowering. Instead of only
allowing the signed optab to provide EQ/NE compares we allow both
here though since there seems to be no documented canonicalization.

Currently, LoongArch ELF psABI is not clear on the handling of zero-
sized fields in aggregates arguments or return values [1]. The behavior
of GCC trunk is puzzling considering the following cases:

float x;

Hi!
cgraph_node has a semantic_interposition flag which should mirror
opt_for_fn (decl, flag_semantic_interposition). But it actually is
initialized not from that, but from flag_semantic_interposition in the
