In get_bit_range() we get the following COMPONENT_REF:
(gdb) call debug_generic_stmt(exp)
MEM[(struct io *)0B].e0;
Then we extract the field so we can search for it in the original
record/structure:
field = TREE_OPERAND (exp, 1);
record_type = DECL_FIELD_CONTEXT (field);
But when we iterate through TYPE_FIELDS(record_type), "field" is not found
because the COMPONENT_REF's field "e0" has a different pointer than the "e0" in
the record itself:
(gdb) call debug_generic_stmt (fld)
e0
(gdb) call debug_generic_stmt (field)
e0
(gdb) p fld == field
$12 = 0
I'm not very LTO savvy. Is this supposed to happen? Should we have been
comparing something else than pointer equality here, or is there something else
broken?
