/* Classifies a SYMBOL_REF, LABEL_REF or UNSPEC address.
|
| 29 |
|
|
|
| 30 |
|
|
SYMBOL_GENERAL
|
| 31 |
|
|
Used when none of the below apply.
|
| 32 |
|
|
|
| 33 |
|
|
SYMBOL_SMALL_DATA
|
| 34 |
|
|
The symbol refers to something in a small data section.
|
| 35 |
|
|
|
| 36 |
|
|
SYMBOL_CONSTANT_POOL
|
| 37 |
|
|
The symbol refers to something in the mips16 constant pool.
|
| 38 |
|
|
|
| 39 |
|
|
SYMBOL_GOT_LOCAL
|
| 40 |
|
|
The symbol refers to local data that will be found using
|
| 41 |
|
|
the global offset table.
|
| 42 |
|
|
|
| 43 |
|
|
SYMBOL_GOT_GLOBAL
|
| 44 |
|
|
Likewise non-local data.
|
| 45 |
|
|
|
| 46 |
|
|
SYMBOL_GOTOFF_PAGE
|
| 47 |
|
|
An UNSPEC wrapper around a SYMBOL_GOT_LOCAL. It represents the
|
| 48 |
|
|
offset from _gp of a GOT page entry.
|
| 49 |
|
|
|
| 50 |
|
|
SYMBOL_GOTOFF_GLOBAL
|
| 51 |
|
|
An UNSPEC wrapper around a SYMBOL_GOT_GLOBAL. It represents the
|
| 52 |
|
|
the offset from _gp of the symbol's GOT entry.
|
| 53 |
|
|
|
| 54 |
|
|
SYMBOL_GOTOFF_CALL
|
| 55 |
|
|
Like SYMBOL_GOTOFF_GLOBAL, but used when calling a global function.
|
| 56 |
|
|
The GOT entry is allowed to point to a stub rather than to the
|
| 57 |
|
|
function itself.
|
| 58 |
|
|
|
| 59 |
|
|
SYMBOL_GOTOFF_LOADGP
|
| 60 |
|
|
An UNSPEC wrapper around a function's address. It represents the
|
| 61 |
|
|
offset of _gp from the start of the function.
|
| 62 |
|
|
|
| 63 |
|
|
SYMBOL_TLS
|
| 64 |
|
|
A thread-local symbol.
|
| 65 |
|
|
|
| 66 |
|
|
SYMBOL_TLSGD
|
| 67 |
|
|
SYMBOL_TLSLDM
|
| 68 |
|
|
SYMBOL_DTPREL
|
| 69 |
|
|
SYMBOL_GOTTPREL
|
| 70 |
|
|
SYMBOL_TPREL
|
| 71 |
|
|
UNSPEC wrappers around SYMBOL_TLS, corresponding to the
|
| 72 |
|
|
thread-local storage relocation operators.
|
| 73 |
|
|
|
| 74 |
|
|
SYMBOL_64_HIGH
|
| 75 |
|
|
For a 64-bit symbolic address X, this is the value of
|
| 76 |
|
|
(%highest(X) << 16) + %higher(X).
|
| 77 |
|
|
|
| 78 |
|
|
SYMBOL_64_MID
|
| 79 |
|
|
For a 64-bit symbolic address X, this is the value of
|
| 80 |
|
|
(%higher(X) << 16) + %hi(X).
|
| 81 |
|
|
|
| 82 |
|
|
SYMBOL_64_LOW
|
| 83 |
|
|
For a 64-bit symbolic address X, this is the value of
|
| 84 |
|
|
(%hi(X) << 16) + %lo(X). */
