29 | /* Classifies a SYMBOL_REF, LABEL_REF or UNSPEC address. |
30 | ||
31 | SYMBOL_GENERAL | |
32 | Used when none of the below apply. | |
33 | ||
34 | SYMBOL_SMALL_DATA | |
35 | The symbol refers to something in a small data section. | |
36 | ||
37 | SYMBOL_CONSTANT_POOL | |
38 | The symbol refers to something in the mips16 constant pool. | |
39 | ||
40 | SYMBOL_GOT_LOCAL | |
41 | The symbol refers to local data that will be found using | |
42 | the global offset table. | |
43 | ||
44 | SYMBOL_GOT_GLOBAL | |
45 | Likewise non-local data. | |
46 | ||
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. | |
50 | ||
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. | |
54 | ||
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. | |
59 | ||
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. | |
63 | ||
69229b81 DJ |
64 | SYMBOL_TLS |
65 | A thread-local symbol. | |
66 | ||
67 | SYMBOL_TLSGD | |
68 | SYMBOL_TLSLDM | |
69 | SYMBOL_DTPREL | |
70 | SYMBOL_GOTTPREL | |
71 | SYMBOL_TPREL | |
72 | UNSPEC wrappers around SYMBOL_TLS, corresponding to the | |
73 | thread-local storage relocation operators. | |
74 | ||
e245bd81 RS |
75 | SYMBOL_64_HIGH |
76 | For a 64-bit symbolic address X, this is the value of | |
77 | (%highest(X) << 16) + %higher(X). | |
78 | ||
79 | SYMBOL_64_MID | |
80 | For a 64-bit symbolic address X, this is the value of | |
81 | (%higher(X) << 16) + %hi(X). | |
82 | ||
83 | SYMBOL_64_LOW | |
84 | For a 64-bit symbolic address X, this is the value of | |
85 | (%hi(X) << 16) + %lo(X). */ | |
