enum llvm::AArch64II::TOF

Target Operand Flag enum.

Enumerator
MO_NO_FLAG
MO_FRAGMENT
MO_PAGE	MO_PAGE - A symbol operand with this flag represents the pc-relative offset of the 4K page containing the symbol. This is used with the ADRP instruction.
MO_PAGEOFF	MO_PAGEOFF - A symbol operand with this flag represents the offset of that symbol within a 4K page. This offset is added to the page address to produce the complete address.
MO_G3	MO_G3 - A symbol operand with this flag (granule 3) represents the high 16-bits of a 64-bit address, used in a MOVZ or MOVK instruction.
MO_G2	MO_G2 - A symbol operand with this flag (granule 2) represents the bits 32-47 of a 64-bit address, used in a MOVZ or MOVK instruction.
MO_G1	MO_G1 - A symbol operand with this flag (granule 1) represents the bits 16-31 of a 64-bit address, used in a MOVZ or MOVK instruction.
MO_G0	MO_G0 - A symbol operand with this flag (granule 0) represents the bits 0-15 of a 64-bit address, used in a MOVZ or MOVK instruction.
MO_HI12	MO_HI12 - This flag indicates that a symbol operand represents the bits 13-24 of a 64-bit address, used in a arithmetic immediate-shifted-left- by-12-bits instruction.
MO_COFFSTUB	MO_COFFSTUB - On a symbol operand "FOO", this indicates that the reference is actually to the ".refptr.FOO" symbol. This is used for stub symbols on windows.
MO_GOT	MO_GOT - This flag indicates that a symbol operand represents the address of the GOT entry for the symbol, rather than the address of the symbol itself.
MO_NC	MO_NC - Indicates whether the linker is expected to check the symbol reference for overflow. For example in an ADRP/ADD pair of relocations the ADRP usually does check, but not the ADD.
MO_TLS	MO_TLS - Indicates that the operand being accessed is some kind of thread-local symbol. On Darwin, only one type of thread-local access exists (pre linker-relaxation), but on ELF the TLSModel used for the referee will affect interpretation.
MO_DLLIMPORT	MO_DLLIMPORT - On a symbol operand, this represents that the reference to the symbol is for an import stub. This is used for DLL import storage class indication on Windows.
MO_S	MO_S - Indicates that the bits of the symbol operand represented by MO_G0 etc are signed.
MO_PREL	MO_PREL - Indicates that the bits of the symbol operand represented by MO_G0 etc are PC relative.
MO_TAGGED	MO_TAGGED - With MO_PAGE, indicates that the page includes a memory tag in bits 56-63. On a FrameIndex operand, indicates that the underlying memory is tagged with an unknown tag value (MTE); this needs to be lowered either to an SP-relative load or store instruction (which do not check tags), or to an LDG instruction to obtain the tag value.
MO_ARM64EC_CALLMANGLE	MO_ARM64EC_CALLMANGLE - Operand refers to the Arm64EC-mangled version of a symbol, not the original. For dllimport symbols, this means it uses "__imp_aux". For other symbols, this means it uses the mangled ("#" prefix for C) name.
