29 /* Classifies a SYMBOL_REF, LABEL_REF or UNSPEC address.
31 SYMBOL_GENERAL
32 Used when none of the below apply.
34 SYMBOL_SMALL_DATA
35 The symbol refers to something in a small data section.
37 SYMBOL_CONSTANT_POOL
38 The symbol refers to something in the mips16 constant pool.
40 SYMBOL_GOT_LOCAL
41 The symbol refers to local data that will be found using
42 the global offset table.
44 SYMBOL_GOT_GLOBAL
45 Likewise non-local data.
47 SYMBOL_GOTOFF_PAGE
48 An UNSPEC wrapper around a SYMBOL_GOT_LOCAL. It represents the
49 offset from _gp of a GOT page entry.
51 SYMBOL_GOTOFF_GLOBAL
52 An UNSPEC wrapper around a SYMBOL_GOT_GLOBAL. It represents the
53 the offset from _gp of the symbol's GOT entry.
55 SYMBOL_GOTOFF_CALL
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
58 function itself.
60 SYMBOL_GOTOFF_LOADGP
61 An UNSPEC wrapper around a function's address. It represents the
62 offset of _gp from the start of the function.
64 SYMBOL_64_HIGH
65 For a 64-bit symbolic address X, this is the value of
66 (%highest(X) << 16) + %higher(X).
68 SYMBOL_64_MID
69 For a 64-bit symbolic address X, this is the value of
70 (%higher(X) << 16) + %hi(X).
72 SYMBOL_64_LOW
73 For a 64-bit symbolic address X, this is the value of
74 (%hi(X) << 16) + %lo(X). */
