◆ EdgeKind_aarch64

enum llvm::jitlink::aarch64::EdgeKind_aarch64 : Edge::Kind

Represents aarch64 fixups and other aarch64-specific edge kinds.

Enumerator
Pointer64	A plain 64-bit pointer value relocation. Fixup expression: Fixup <- Target + Addend : uint64
Pointer64Authenticated	An arm64e authenticated pointer relocation. The addend contains a 64-bit struct containing the authentication parameters: Addend encoding: int32_t addend; uint16_t diversityData; uint16_t hasAddressDiversity : 1; uint16_t key : 2; uint16_t zeroes : 12; uint16_t authenticated : 1; Note: This means that the addend cannot be interpreted as a plain offset prior to lowering. Authenticated pointer edges cannot be fixed up directly by JITLink as the signing keys are held in the executing process. They can be removed from the graph by a combination of the createEmptyPointerSigningFunction pass (post-prune) and the lowerPointer64AuthEdgesToSigningFunction pass (pre-fixup). Together these passes construct a signing function that will be run in the executing process to write the signed pointers to the fixup locations. Fixup expression: NONE Errors: Failure to handle edges of this kind prior to the fixup phase will result in an unsupported error during the fixup phase.
Pointer32	A plain 32-bit pointer value relocation. Fixup expression: Fixup <- Target + Addend : uint32 Errors: The target must reside in the low 32-bits of the address space, otherwise an out-of-range error will be returned.
Delta64	A 64-bit delta. Delta from the fixup to the target. Fixup expression: Fixup <- Target - Fixup + Addend : int64
Delta32	A 32-bit delta. Delta from the fixup to the target. Fixup expression: Fixup <- Target - Fixup + Addend : int64 Errors: The result of the fixup expression must fit into an int32, otherwise an out-of-range error will be returned.
NegDelta64	A 64-bit negative delta. Delta from target back to the fixup. Fixup expression: Fixup <- Fixup - Target + Addend : int64
NegDelta32	A 32-bit negative delta. Delta from the target back to the fixup. Fixup expression: Fixup <- Fixup - Target + Addend : int32 Errors: The result of the fixup expression must fit into an int32, otherwise an out-of-range error will be returned.
Branch26PCRel	A 26-bit PC-relative branch. Represents a PC-relative call or branch to a target within +/-128Mb. The target must be 32-bit aligned. Fixup expression: Fixup <- (Target - Fixup + Addend) >> 2 : int26 Notes: The '26' in the name refers to the number operand bits and follows the naming convention used by the corresponding ELF and MachO relocations. Since the low two bits must be zero (because of the 32-bit alignment of the target) the operand is effectively a signed 28-bit number. Errors: The result of the unshifted part of the fixup expression must be 32-bit aligned otherwise an alignment error will be returned. The result of the fixup expression must fit into an int26 otherwise an out-of-range error will be returned.
TestAndBranch14PCRel	A 14-bit PC-relative test and branch. Represents a PC-relative test and branch to a target within +/-32Kb. The target must be 32-bit aligned. Fixup expression: Fixup <- (Target - Fixup + Addend) >> 2 : int14 Notes: The '14' in the name refers to the number operand bits and follows the naming convention used by the corresponding ELF relocation. Since the low two bits must be zero (because of the 32-bit alignment of the target) the operand is effectively a signed 16-bit number. Errors: The result of the unshifted part of the fixup expression must be 32-bit aligned otherwise an alignment error will be returned. The result of the fixup expression must fit into an int14 otherwise an out-of-range error will be returned.
CondBranch19PCRel	A 19-bit PC-relative conditional branch. Represents a PC-relative conditional branch to a target within +/-1Mb. The target must be 32-bit aligned. Fixup expression: Fixup <- (Target - Fixup + Addend) >> 2 : int19 Notes: The '19' in the name refers to the number operand bits and follows the naming convention used by the corresponding ELF relocation. Since the low two bits must be zero (because of the 32-bit alignment of the target) the operand is effectively a signed 21-bit number. Errors: The result of the unshifted part of the fixup expression must be 32-bit aligned otherwise an alignment error will be returned. The result of the fixup expression must fit into an int19 otherwise an out-of-range error will be returned.
MoveWide16	A 16-bit slice of the target address (which slice depends on the instruction at the fixup location). Used to fix up MOVK/MOVN/MOVZ instructions. Fixup expression: Fixup <- (Target + Addend) >> Shift : uint16 where Shift is encoded in the instruction at the fixup location.
LDRLiteral19	The signed 21-bit delta from the fixup to the target. Typically used to load a pointers at a PC-relative offset of +/- 1Mb. The target must be 32-bit aligned. Fixup expression: Fixup <- (Target - Fixup + Addend) >> 2 : int19 Notes: The '19' in the name refers to the number operand bits and follows the naming convention used by the corresponding ELF relocation. Since the low two bits must be zero (because of the 32-bit alignment of the target) the operand is effectively a signed 21-bit number. Errors: The result of the unshifted part of the fixup expression must be 32-bit aligned otherwise an alignment error will be returned. The result of the fixup expression must fit into an int19 or an out-of-range error will be returned.
ADRLiteral21	The signed 21-bit delta from the fixup to the target. Fixup expression: Fixup <- Target - Fixup + Addend : int21 Notes: For ADR fixups. Errors: The result of the fixup expression must fit into an int21 otherwise an out-of-range error will be returned.
Page21	The signed 21-bit delta from the fixup page to the page containing the target. Fixup expression: Fixup <- (((Target + Addend) & ~0xfff) - (Fixup & ~0xfff)) >> 12 : int21 Notes: For ADRP fixups. Errors: The result of the fixup expression must fit into an int21 otherwise an out-of-range error will be returned.
PageOffset12	The 12-bit (potentially shifted) offset of the target within its page. Typically used to fix up LDR immediates. Fixup expression: Fixup <- ((Target + Addend) >> Shift) & 0xfff : uint12 where Shift is encoded in the size field of the instruction. Errors: The result of the unshifted part of the fixup expression must be aligned otherwise an alignment error will be returned. The result of the fixup expression must fit into a uint12 otherwise an out-of-range error will be returned.
GotPageOffset15	The 15-bit offset of the GOT entry from the GOT table. Used for load/store instructions addressing a GOT entry. Fixup expression: Fixup <- ((Target + Addend - Page(GOT))) & 0x7fff) >> 3 : uint12 Errors: The result of the unshifted part of the fixup expression must be aligned otherwise an alignment error will be returned. The result of the fixup expression must fit into a uint12 otherwise an out-of-range error will be returned.
RequestGOTAndTransformToPage21	A GOT entry getter/constructor, transformed to Page21 pointing at the GOT entry for the original target. Indicates that this edge should be transformed into a Page21 targeting the GOT entry for the edge's current target, maintaining the same addend. A GOT entry for the target should be created if one does not already exist. Edges of this kind are usually handled by a GOT builder pass inserted by default. Fixup expression: NONE Errors: ASSERTION Failure to handle edges of this kind prior to the fixup phase will result in an assert/unreachable during the fixup phase.
RequestGOTAndTransformToPageOffset12	A GOT entry getter/constructor, transformed to Pageoffset12 pointing at the GOT entry for the original target. Indicates that this edge should be transformed into a PageOffset12 targeting the GOT entry for the edge's current target, maintaining the same addend. A GOT entry for the target should be created if one does not already exist. Edges of this kind are usually handled by a GOT builder pass inserted by default. Fixup expression: NONE Errors: ASSERTION Failure to handle edges of this kind prior to the fixup phase will result in an assert/unreachable during the fixup phase.
RequestGOTAndTransformToPageOffset15	A GOT entry getter/constructor, transformed to Pageoffset15 pointing at the GOT entry for the original target. Indicates that this edge should be transformed into a GotPageOffset15 targeting the GOT entry for the edge's current target, maintaining the same addend. A GOT entry for the target should be created if one does not already exist. Fixup expression: NONE Errors: ASSERTION Failure to handle edges of this kind prior to the fixup phase will result in an assert/unreachable during the fixup phase.

Indicates that this edge should be transformed into a Delta32/ targeting the GOT entry for the edge's current target, maintaining the same addend. A GOT entry for the target should be created if one does not already exist. Edges of this kind are usually handled by a GOT builder pass inserted by default. Fixup expression: NONE Errors: ASSERTION Failure to handle edges of this kind prior to the fixup phase will result in an assert/unreachable during the fixup phase.
RequestTLVPAndTransformToPage21	A TLVP entry getter/constructor, transformed to Page21. Indicates that this edge should be transformed into a Page21 targeting the TLVP entry for the edge's current target. A TLVP entry for the target should be created if one does not already exist. Fixup expression: NONE Errors: ASSERTION Failure to handle edges of this kind prior to the fixup phase will result in an assert/unreachable during the fixup phase.
