10 // Torture test for weakrefs. The first letter of an identifier
11 // indicates whether/how it is defined; the second letter indicates
12 // whether it is part of a variable or function test; the number that
13 // follows is a test counter, and a letter that may follow enables
14 // multiple identifiers within the same test (e.g., multiple weakrefs
15 // or pointers to the same identifier).
17 // Identifiers starting with W are weakrefs; those with p are
18 // pointers; those with g are global definitions; those with l are
19 // local definitions; those with w are expected to be weak undefined
20 // in the symbol table; those with u are expected to be marked as
21 // non-weak undefined in the symbol table.
