Hi,
This patch fixes PR91137 by finding base objects with walk_tree utility. Note
we specially return
integer_zero_node when a tree expression contains multiple base objects. This
works since the
special node is compared unequal to any real base object, thus skipped in
candidate selection.

Hi,
this is the hunk we omitted from the original patch enabling TBAA for
ODR types. Currently record_component_aliases record all pointers as
void *. This is because canonical type merging handles them this way
and thus it may merge for example
strut a { int *ptr;};
and
struct b { short *ptr
Many places in the parser follow the same pattern of capturing the location
of the last lexed token, either before or after lexing it, and then using
that as the end of a location range; this can be simplified by passing the
lexer to make_location and grabbing the token location there.
