Enumeration Type Documentation

◆ TOF

Target Operand Flag enum.

Enumerator
MO_NO_FLAG 
MO_ABSOLUTE_ADDRESS 

On a symbol operand this indicates that the immediate is the absolute address of the symbol.

MO_PC_RELATIVE_ADDRESS 

On a symbol operand this indicates that the immediate is the pc-relative address of the symbol.

MO_GOT 

On a symbol operand this indicates that the immediate is the offset to the GOT entry for the symbol name from the base of the GOT.

name@GOT

MO_GOTOFF 

On a symbol operand this indicates that the immediate is the offset to the location of the symbol name from the base of the GOT.

name@GOTOFF

MO_GOTPCREL 

On a symbol operand this indicates that the immediate is offset to the GOT entry for the symbol name from the current code location.

name@GOTPCREL

MO_PLT 

On a symbol operand this indicates that the immediate is offset to the PLT entry of symbol name from the current code location.

name@PLT

MO_TLSGD 

On a symbol operand, this indicates that the immediate is the offset to the slot in GOT which stores the information for accessing the TLS variable.

This is used when operating in Global Dynamic mode. name@TLSGD

MO_TLSLD 

On a symbol operand, this indicates that the immediate is the offset to variable within the thread local storage when operating in Local Dynamic mode.

name@TLSLD

MO_TLSLDM 

On a symbol operand, this indicates that the immediate is the offset to the slot in GOT which stores the information for accessing the TLS variable.

This is used when operating in Local Dynamic mode. name@TLSLDM

MO_TLSIE 

On a symbol operand, this indicates that the immediate is the offset to the variable within the thread local storage when operating in Initial Exec mode.

name@TLSIE

MO_TLSLE 

On a symbol operand, this indicates that the immediate is the offset to the variable within in the thread local storage when operating in Local Exec mode.

name@TLSLE
