PR driver/71651 identifies an issue where the driver can make
nonsensical suggestions for options flagged as RejectNegative:

This patch stops breaking up
(side-effect, lval) = rval;
into
side-effect;
lval = rval;
because now the RHS is required to be sequenced before the LHS. And
other complex LHS that were broken out similarly are now turned into
COMPOUND_EXPR.
This revealed a bug in verify_tree's handling of COMPO
While working on C++17 evaluation order, I noticed that
get_target_expr was breaking on bit-fields because it tried to create
a temporary object of bit-field type, which doesn't exist in C++. If
we copy a bit-field into a temporary it should have the real type of
the expression.

Hi!
The following testcase got broken when we started to test compatibility
of argument types of builtins - the fact that omp-low.c emitted
e.g. int or various other types for the last argument of

rewrite_expr_tree tries to reuse SSA_NAMEs if it knows they hold the same

Hi all,
In this PR we get an ICE when trying to emit a conditional move through
noce_convert_multiple_sets.
The comment in the patch explains the situation but we get a two-instruction
sequence like:

(reg:SI 88 [ _4 ])) wice.c:8 82 {*movsi_intern
