Keeps track of jump tables referenced by lowered switch instructions.
Declared in <llvm/CodeGen/MachineJumpTableInfo.h>
class MachineJumpTableInfo;Instructions reference the address of these jump tables through MO_JumpTableIndex values. When emitting assembly or machine code, these virtual address references are converted to refer to the address of the function jump tables.
| Name | Description |
|---|---|
JTEntryKind | JTEntryKind - This enum indicates how each entry of the jump table is represented and emitted. |
| Name | Description |
|---|---|
MachineJumpTableInfo [constructor] | Construct jump table info with the given entry encoding kind. |
RemoveJumpTable | RemoveJumpTable - Mark the specific index as being dead. This will prevent it from being emitted. |
RemoveMBBFromJumpTables | RemoveMBBFromJumpTables - If MBB is present in any jump tables, remove it. |
ReplaceMBBInJumpTable | ReplaceMBBInJumpTable - If Old is a target of the jump tables, update the jump table to branch to New instead. |
ReplaceMBBInJumpTables | ReplaceMBBInJumpTables - If Old is the target of any jump tables, update the jump tables to branch to New instead. |
