isCPI - Tests if this is a MO_ConstantPoolIndex operand.

Determine whether the passed iterator points to the callee operand's Use.

Return true if @p UI is the use that defines the callee of this ACS.

Has the callee saved info been calculated yet?

Physical registers that may be modified within a function but are guaranteed to be restored before any uses. This is useful for targets that have call

Return 'true' if the clause and index Idx is a catch clause.

Return 'true' if this landingpad instruction is a cleanup. I.e., it should be run when unwinding even if its landing pad doesn't catch the exception.

Returns true if this is the entry block of a cleanup funclet.

Tests if this is an Order dependence that is marked as "cluster", meaning it is artificial and wants to be adjacent.

Return true if the instruction is a "coalescable" extension instruction. That is, it's like a copy where it's legal for the source to overlap the dest

A collapsed DomainValue has no instructions to twiddle - it simply keeps track of the domains where the registers are already available.

Return true if this may be a 2- or 3-address instruction (of the form "X = op Y, Z, ..."), which produces the same result if Y and Z are exchanged. I

@returns true if the predicate of this ICmpInst is commutative Determine if this relation is commutative.

@returns true if the predicate of this instruction is commutative. Determine if this is a commutative predicate.

Return true if swapping the first two arguments to the intrinsic produces the same result.

Returns true if the opcode is a commutative binary operation.

Return true if this instruction is a comparison.

Returns true if this SDNode represents cmpxchg atomic operation, false otherwise.

\returns true if this memory access is legal with for the access described by \p Other (The alignment is sufficient for the size and result type).

Test if a DataLayout if compatible with the CodeGen for this target. The LLVM Module owns a DataLayout that is used for the target independent optimi

Is this a complete value with no unset (uninitialized) subvalues?

If the PHI node is complete which means all of its parent's predecessors have incoming value in this PHI, return true, otherwise return false.

Returns true if the op does a compression to the vector before storing. The node contiguously stores the active elements (integers or floats) in src (

Returns true if the op does a compression to the vector before storing. The node contiguously stores the active elements (integers or floats) in src (

Is this a concrete and fully resolved value without any references or stuck operations? Unset values are concrete.

Return true if the specified condition code is legal on this target.

Return true if the specified condition code is legal or custom on this target.

Return true if this is a branch which may fall through to the next instruction or may transfer control flow to some other block. The TargetInstrInfo:

If the value is a global constant, its value is immutable throughout the runtime execution of the program. Assigning a value into the constant leads

\returns true if a constant G_UBFX is legal on the target.

\returns true if \p N is any kind of constant or build_vector of constants, int or float. If a vector, it may not necessarily be a splat.

Determine if the call is convergent.

Determine if the invoke is convergent

Return true if this instruction is convergent. Convergent instructions can not be made control-dependent on any additional values.

Return true if this is a 2-address instruction which can be changed into a 3-address instruction if needed. Doing this transformation can be profitab

If the specific machine instruction is a instruction that moves/copies value from one register to another register return destination and source regis

Target-dependent implementation for IsCopyInstr. If the specific machine instruction is a instruction that moves/copies value from one register to ano

Return true if the instruction behaves like a copy. This does not include native copy instructions.

Return true if ctlz instruction is fast.

Tests if this is not an SDep::Data dependence.

Return true if this instruction has a dead def.

Returns true if the specified index corresponds to a dead object.

Test if the DataLayout was constructed from an empty string.

Returns true if the exception handling behavior and rounding mode match what is used in the default floating point environment.

Return true if the currently visible definition of this global (if any) is exactly the definition we will see at runtime. Non-exact linkage types inh

Check if this is deleted member function. Return true if this subprogram is a C++11 special member function declared deleted.

Return true if this is a "deopt" operand bundle.

Returns true if MI is a dependency breaking instruction for the subtarget. Similar in behavior to `isZeroIdiom`. However, it knows how to identify al

Return true if it is profitable to move this shift by a constant amount though its operand, adjusting any immediate operands as necessary to preserve

Return true if it is profitable for dag combiner to transform a floating point op of specified opcode to a equivalent op of an integer type. e.g. f32

Return true if this ACS represents a direct call.

Return true if the LR is currently in an invalid state, and flush() needs to be called.

Whether the definition of this global may be discarded if it is not used in its compilation unit.
