omputed indices to reference locview
extensions to loclists. That would be a significant amount of work for
little to no benefit AFAICT, and only on the short term. In the long
term, I expect/hope some way to represent locviews to be adopted in
standard DWARF.

realize it was supposed to be rejected.

t's good knowledge to have. I've added asserts and comments.
Here's what I'm testing.
[PR86379] do not use TREE_TYPE for USING_DECL_SCOPE
From: Alexandre Oliva
It's too risk to reuse the type field for USING_DECL_SCOPE.
Language-independent parts of the compiler, such as location and
non-lvalue
ymbol naming, e.g. if it appears in an
initializer of a data member.
Here's the patch I'm testing. OK if it passes?

From: Alexandre Oliva
A lambda capture variable initialized with a lambda expr taking more
than one parameter got us confused.
The first problem was that the parameter list was cut short during
tsubsting because we tsubsted it with cp_unevaluated_operand. We
reset it right after, to tsubst

ase, I suppose we should document that, and then we just use

It's (so far) a single use function, so it will likely be inlined even
wit
akes the DECL_CONTEXT of decl and adjusts the properties of
that class. If we followed USING_DECLs in decl that early, we'd adjust
(again?) the member properties of USING_DECL_SCOPE(original using decl),
rather than of DECL_CONTEXT (original using decl) as intended.
