Returns true if the set is empty.

Return true if no instructions have been inserted in this bundle yet. Empty bundles aren't representable in a MachineBasicBlock.

Return true if this DFSResult is uninitialized. resize() initializes DFSResult, while compute() populates it.

empty - Return true if there is any lexical scope information available.

Returns true if the set is empty.

Return true if target always benefits from combining into FMA for a given value type. This must typically return false on targets where FMA takes more

For targets which want to use big-endian can enable it with enableBigEndian() hook

Enable the use of the early if conversion pass.

Return true if the target wants to use the optimization that turns ext(promotableInst1(...(promotableInstN(load)))) into promotedInst1(...(promotedIns

True if the subtarget should run MachinePipeliner

True if the machine scheduler should disable the TLI preference for preRA scheduling with the source level scheduler.

Allow the target to enable a specific standard pass by default.

Returns true if the target will correctly handle shrink wrapping.

Returns true if the stack slot holes in the fixed and callee-save stack area should be used when allocating other stack locations to reduce stack size

Enable tracking of subregister liveness in register allocator. Please use MachineRegisterInfo::subRegLivenessEnabled() instead where possible.

Get an iterator to the end of the symbol table.

Returns an iterator to the bottom of the current scheduling region.

Returns an iterator past the last iteration.

Returns an iterator past the last iteration.

Process end of a basic block during basic block sections.

endNumber - return the maximum point of the range of the whole, exclusive.

Return the end point of the last live range segment to interact with the instruction, if any. The end point is an invalid SlotIndex only if the live

ensureAlignment - Make sure the function is at least A bytes aligned.

Get the synthetic entry count for this function.

Remove a range of instructions from the instruction list and delete them.

eraseNode - Removes a node from the dominator tree. Block must not dominate any other blocks. Removes node from its immediate dominator's children li

Remove an instruction from the instruction list and delete it. If the instruction is part of a bundle, the other instructions in the bundle will stil

Returns true if the given alignment exceeds the natural stack alignment.

Query whether there is equivalent in the remapper which has been inserted.

Expands target specific indirect branch for the case of JumpTable expanasion.

This function is called for all pseudo instructions that remain after register allocation. Many pseudo instructions are created to help register alloc

exposesReturnsTwice - Returns true if the function calls setjmp or any other similar functions with attribute "returns twice" without having the attri

Visit the elements via ExprOperand wrappers. These range iterators visit elements through \a ExprOperand wrappers. This is not guaranteed to be a val

extendInsnRange - Extend the current instruction range covered by this scope.

Create a new AAMDNode that describes this AAMDNode after extending it to apply to a series of bytes of length Len. A size of -1 denotes an unknown siz
