rtx_equal_p uses:
case SYMBOL_REF:
return XSTR (x, 0) == XSTR (y, 0);
to check whether two symbol_refs are equal. This means that genattrtab,
which uses rtx_equal_p, must create unique strings for them.
attr_rtx has code to create unique strings, and I think it originally

Like the recent MEM_ATTRS changes, this patch is supposed to help the
transition to const_ints with modes. However, like those changes,
I think it makes sense on its own.
At the moment, the canonical way of testing a C condition in an
.md attribute is to use:
(ne (symbol_ref "TEST") (const_i

For now, it changes the return value to "-3" for two cases:

Hello,
this patch fixes PR 50071 where statement labels in a type definition where
hooked to the parent scoping unit instead of the type scoping unit.
From the standard:
- statement label (3.2.5):
The same statement label shall not be given to more than one statement in its
scope.
- scoping u

We were failing to print MODIFY_EXPR properly. I'm surprised that
didn't turn up before now.

While looking at 48370, I noticed that this bit of code in
initialize_reference really ought to be in grok_reference_init instead,
since it only applied to top-level references.
