29 /* Classifies a SYMBOL_REF, LABEL_REF or UNSPEC address.
32 Used when none of the below apply.
35 The symbol refers to something in a small data section.
38 The symbol refers to something in the mips16 constant pool.
41 The symbol refers to local data that will be found using
42 the global offset table.
45 Likewise non-local data.
48 An UNSPEC wrapper around a SYMBOL_GOT_LOCAL. It represents the
49 offset from _gp of a GOT page entry.
52 An UNSPEC wrapper around a SYMBOL_GOT_GLOBAL. It represents the
53 the offset from _gp of the symbol's GOT entry.
56 Like SYMBOL_GOTOFF_GLOBAL, but used when calling a global function.
57 The GOT entry is allowed to point to a stub rather than to the
61 An UNSPEC wrapper around a function's address. It represents the
62 offset of _gp from the start of the function.
65 A thread-local symbol.
72 UNSPEC wrappers around SYMBOL_TLS, corresponding to the
73 thread-local storage relocation operators.
76 For a 64-bit symbolic address X, this is the value of
77 (%highest(X) << 16) + %higher(X).
80 For a 64-bit symbolic address X, this is the value of
81 (%higher(X) << 16) + %hi(X).
84 For a 64-bit symbolic address X, this is the value of
85 (%hi(X) << 16) + %lo(X). */
