| /* 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). */ |
