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