Transforms a LaneMask computed for one subregister to the lanemask that would have been computed when composing the subsubregisters with IdxA first. @

Overridden by TableGen in targets that have sub-registers.

Return the subregister index you get from composing two subregister indices. The special null sub-register index composes as the identity. If R:a:b

Overridden by TableGen in targets that have sub-registers.

Summarize node functions for the entire node set.

Return true if the builder has the specified attribute.

Return true if the index is covered by this segment.

Returns true if register \p Reg is contained in the set. This also works if only the super register of \p Reg has been defined, because addReg() alway

Return true if the specified register is included in this register class. This does not include virtual registers.

Return true if the given interval, [S, E), is covered by this segment.

containsValue - Returns true if VNI belongs to this range.

Allocate and initialize an instance of the YAML representation of the MachineFunctionInfo.

This function is used to implement the list slice selection operator. Given a value, it selects the specified list elements, returning them as a new

This function is used to implement the bit range selection operator. Given a value, it selects the specified bits, returning them as a new \p Init of

Return true if a select of constants (select Cond, C1, C2) should be transformed into simple math ops with the condition value. For example: select Co

Use bitwise logic to make pairs of compares more efficient. For example: and (seteq A, B), (seteq C, D) --> seteq (or (xor A, B), (xor C, D)), 0 This

This method must be implemented by targets that set the M_CONVERTIBLE_TO_3_ADDR flag. When this flag is set, the target may be able to convert a two-

Get the cost of a copy from \p B to \p A, or put differently, get the cost of A = COPY B. Since register banks may cover different size, \p Size speci

Propagate the fast-math-flags from an IR FPMathOperator.

Convenience function for copying all fast-math flags. All values in FMF are transferred to this operator.

Copy from the parameter into this VNInfo.

Emit instructions to copy a pair of physical registers. This function should support copies within any legal register class as well as any cross-clas

Copy the underlying value. This should get optimized down to a simple copy. We need to actually construct the value, rather than calling memcpy, to

\brief Count number of 0's from the most significant bit to the least stopping at the first 1. Only unsigned integral types are allowed. \param ZB t

Return the number of operand bundles with the tag Name attached to this instruction.

Return metadata appropriate for an alias scope domain node. Each returned node is distinct from all other metadata and will never be identified (uniqu

Return metadata appropriate for a TBAA root node. Each returned node is distinct from all other metadata and will never be identified (uniqued) with a

Create an expression for a variable that does not have an address, but does have a constant value.

Create a context vector from a given context string and save it in `Context`.

Create a DataLayout.

Allocate and return a default initialized instance of the YAML representation for the MachineFunctionInfo.

This method returns a target specific FastISel object, or null if the target does not support "fast" ISel.

Create an instance of ScheduleDAGInstrs to be run within the standard MachineScheduler pass for this function and target at the current optimization l

During PHI eleimination lets target to make necessary checks and insert the copy to the PHI destination register in a target specific manner.

During PHI eleimination lets target to make necessary checks and insert the copy to the PHI destination register in a target specific manner.

Similar to createMachineScheduler but used when postRA machine scheduling is enabled.

Creates a new empty subregister live range. The range is added at the beginning of the subrange list; subrange iterators stay valid.

Like createSubRange() but the new range is filled with a copy of the liveness information in @p CopyFrom.

Create a copy of the given value. The new value will be identical except for the Value number.
