+ clang_analyzer_dump_int(p - pn); // expected-warning-re {{0 -
(reg_${{[0-9]+}}<int n>)}}
+ clang_analyzer_dump_int((p + 1) - q); // expected-warning {{Unknown}} //
FIXME: Might point to the same region, we should hold the expression 'p+1+q'
instead.
+ clang_analyzer_dump_int((p + 1) - p); // expected-warning {{1 S32b}}
----------------
The suggested expression should be `p+1-q`.

----------------
The suggested expression should be `q-p+1`.
