RemoveJumpTable - Mark the specific index as being dead. This will prevent it from being emitted.

Remove or mark dead a statically sized stack object.

Replace all uses of \c F with \c T, then remove \c F from the DAG.

This callback is invoked when a node result type is illegal for the target, and the operation was registered to use 'custom' lowering for that result

ReplaceUses - replace all uses of the old node F with the use of the new node T.

Move node N in the AllNodes list to be immediately before the given iterator Position. This may be used to update the topological ordering when the li

Create an SDNode. SDNodes are created without any operands, and never own the operand storage. To add operands, see SelectionDAG::createOperands.

Default constructor turns off all optimization flags.

Constructs a null SDep. This is only for use by container classes which require default constructors. SUnits may not/ have null SDep edges.

Constructs an SUnit for pre-regalloc scheduling to represent an SDNode and any nodes flagged to it.

Pending queues extend the ready queues with the same ID and the PendingFlag set.

SelectInlineAsmMemoryOperand - Select the specified address as a target addressing mode, according to the specified constraint. If this does not matc

Set current context and all callee contexts to be synthetic.

If this builder has a current debug location, set it on the specified instruction.

ShouldPreferAnother - This callback may be invoked if getHazardType returns NoHazard. If, even though there is no hazard, it would be better to schedu

If true, then instruction selection should seek to shrink the FP constant of the specified type to a smaller type in order to save space and / or redu
