Enumeration Type Documentation

anonymous enum

Enumerator:

Pseudo
RawFrm	Raw - This form is for instructions that don't have any operands, so they are just a fixed opcode value, like 'leave'.
AddRegFrm	AddRegFrm - This form is used for instructions like 'push r32' that have their one register operand added to their opcode.
MRMDestReg	MRMDestReg - This form is used for instructions that use the Mod/RM byte to specify a destination, which in this case is a register.
MRMDestMem	MRMDestMem - This form is used for instructions that use the Mod/RM byte to specify a destination, which in this case is memory.
MRMSrcReg	MRMSrcReg - This form is used for instructions that use the Mod/RM byte to specify a source, which in this case is a register.
MRMSrcMem	MRMSrcMem - This form is used for instructions that use the Mod/RM byte to specify a source, which in this case is memory.
MRM0r	MRM[0-7][rm] - These forms are used to represent instructions that use a Mod/RM byte, and use the middle field to hold extended opcode information. In the intel manual these are represented as /0, /1, ...

enum llvm::X86II::TOF

Target Operand Flag enum.

Enumerator:

MO_NO_FLAG
MO_GOT_ABSOLUTE_ADDRESS	MO_GOT_ABSOLUTE_ADDRESS - On a symbol operand, this represents a relocation of: SYMBOL_LABEL + [. - PICBASELABEL]
MO_PIC_BASE_OFFSET	MO_PIC_BASE_OFFSET - On a symbol operand this indicates that the immediate should get the value of the symbol minus the PIC base label: SYMBOL_LABEL - PICBASELABEL
MO_GOT	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. See the X86-64 ELF ABI supplement for more details. SYMBOL_LABEL
MO_GOTOFF	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. See the X86-64 ELF ABI supplement for more details. SYMBOL_LABEL
MO_GOTPCREL	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. See the X86-64 ELF ABI supplement for more details. SYMBOL_LABEL
MO_PLT	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. See the X86-64 ELF ABI supplement for more details. SYMBOL_LABEL
MO_TLSGD	MO_TLSGD - On a symbol operand this indicates that the immediate is some TLS offset. See 'ELF Handling for Thread-Local Storage' for more details. SYMBOL_LABEL
MO_GOTTPOFF	MO_GOTTPOFF - On a symbol operand this indicates that the immediate is some TLS offset. See 'ELF Handling for Thread-Local Storage' for more details. SYMBOL_LABEL
MO_INDNTPOFF	MO_INDNTPOFF - On a symbol operand this indicates that the immediate is some TLS offset. See 'ELF Handling for Thread-Local Storage' for more details. SYMBOL_LABEL
MO_TPOFF	MO_TPOFF - On a symbol operand this indicates that the immediate is some TLS offset. See 'ELF Handling for Thread-Local Storage' for more details. SYMBOL_LABEL
MO_NTPOFF	MO_NTPOFF - On a symbol operand this indicates that the immediate is some TLS offset. See 'ELF Handling for Thread-Local Storage' for more details. SYMBOL_LABEL
MO_DLLIMPORT	MO_DLLIMPORT - On a symbol operand "FOO", this indicates that the reference is actually to the "__imp_FOO" symbol. This is used for dllimport linkage on windows.
MO_DARWIN_STUB	MO_DARWIN_STUB - On a symbol operand "FOO", this indicates that the reference is actually to the "FOO$stub" symbol. This is used for calls and jumps to external functions on Tiger and before.
MO_DARWIN_NONLAZY	MO_DARWIN_NONLAZY - On a symbol operand "FOO", this indicates that the reference is actually to the "FOO$non_lazy_ptr" symbol, which is a non-PIC-base-relative reference to a non-hidden dyld lazy pointer stub.
MO_DARWIN_NONLAZY_PIC_BASE	MO_DARWIN_NONLAZY_PIC_BASE - On a symbol operand "FOO", this indicates that the reference is actually to "FOO$non_lazy_ptr - PICBASE", which is a PIC-base-relative reference to a non-hidden dyld lazy pointer stub.
MO_DARWIN_HIDDEN_NONLAZY_PIC_BASE	MO_DARWIN_HIDDEN_NONLAZY_PIC_BASE - On a symbol operand "FOO", this indicates that the reference is actually to "FOO$non_lazy_ptr -PICBASE", which is a PIC-base-relative reference to a hidden dyld lazy pointer stub.
