+/* Classifies a SYMBOL_REF, LABEL_REF or UNSPEC address.
+
+ SYMBOL_GENERAL
+ Used when none of the below apply.
+
+ SYMBOL_SMALL_DATA
+ The symbol refers to something in a small data section.
+
+ SYMBOL_CONSTANT_POOL
+ The symbol refers to something in the mips16 constant pool.
+
+ SYMBOL_GOT_LOCAL
+ The symbol refers to local data that will be found using
+ the global offset table.
+
+ SYMBOL_GOT_GLOBAL
+ Likewise non-local data.
+
+ SYMBOL_GOTOFF_PAGE
+ An UNSPEC wrapper around a SYMBOL_GOT_LOCAL. It represents the
+ offset from _gp of a GOT page entry.
+
+ SYMBOL_GOTOFF_GLOBAL
+ An UNSPEC wrapper around a SYMBOL_GOT_GLOBAL. It represents the
+ the offset from _gp of the symbol's GOT entry.
+
+ SYMBOL_GOTOFF_CALL
+ Like SYMBOL_GOTOFF_GLOBAL, but used when calling a global function.
+ The GOT entry is allowed to point to a stub rather than to the
+ function itself.
+
+ SYMBOL_GOTOFF_LOADGP
+ An UNSPEC wrapper around a function's address. It represents the
+ offset of _gp from the start of the function.
+
+ SYMBOL_64_HIGH
+ For a 64-bit symbolic address X, this is the value of
+ (%highest(X) << 16) + %higher(X).
+
+ SYMBOL_64_MID
+ For a 64-bit symbolic address X, this is the value of
+ (%higher(X) << 16) + %hi(X).
+
+ SYMBOL_64_LOW
+ For a 64-bit symbolic address X, this is the value of
+ (%hi(X) << 16) + %lo(X). */
