This callback is used to inspect load/store instructions and add target-specific MachineMemOperand flags to them. The default implementation does not

Targets that have a special convention for their symbols could use this hook to return a specialized symbol.

Return a temporary node. For use in constructing cyclic MDNode structures. A temporary MDNode is not uniqued, may be RAUW'd, and must be manually del

Given an intrinsic, checks if on the target the intrinsic will need to map to a MemIntrinsicNode (touches memory). If this is the case, it returns tru

getThumbImmNonShiftedVal - If V is a value that satisfies isThumbImmShiftedVal, return the non-shiftd value.

Difference in tombstone is that the Optional is meaningful.

Access toplevel manager

Get the total execution count of all instantiations in this group.

getTransientStackAlignment - This method returns the number of bytes to which the stack pointer must be aligned at all times, even between calls.

Try to calculate arithmetic and shuffle op costs for reduction intrinsics. We're assuming that reduction operation are performing the following way:

Returns the llvm::Value containing the number of loop iterations. It must be valid in the preheader and always interpreted as an unsigned integer of a

Get the constant value for i1 true.

This static method gets a VectorType with the same number of elements as the input type, and the element type is an integer or float type which is hal

Get the type of the field value as a RecTy.

Overload to return most specific vector type.

Overload to return most specific vector type.

getType - InlineAsm's are always pointers.

Global values are always pointers.

getType - Specialize the getType() method to always return an IntegerType, which reduces the amount of casting needed in parts of the compiler.

Specialize the getType() method to always return an ArrayType, which reduces the amount of casting needed in parts of the compiler.

Specialization - reduce amount of casting.

Specialize the getType() method to always return a FixedVectorType, which reduces the amount of casting needed in parts of the compiler.

Specialize the getType() method to always return an PointerType, which reduces the amount of casting needed in parts of the compiler.

Specialize the getType() method to always return an ArrayType, which reduces the amount of casting needed in parts of the compiler.

Specialize the getType() method to always return a FixedVectorType, which reduces the amount of casting needed in parts of the compiler.

Get the low-level type of \p Reg or LLT{} if Reg is not a generic (target independent) virtual register.

Returns the offset in bytes between successive objects of the specified type, including alignment padding. If Ty is a scalable vector type, the scala

Return the type that should be used to zero or sign extend a zeroext/signext integer return value. FIXME: Some C calling conventions require the retu

For the given \p TypeId, this returns the TypeIdCompatibleVtableMap entry if present in the summary map. This may be used when importing.

This returns either a pointer to the type id summary (if present in the summary map) or null (if not present). This may be used when importing.

The implementation of this method is provided inline as it is particularly well suited to constant folding when called on a specific Type subclass.

Returns the maximum number of bits that may be overwritten by storing the specified type; always a multiple of 8. If Ty is a scalable vector type, th

For types supported by the target, this is an identity function. For types that must be expanded (i.e. integer types that are larger than the largest

If the action for this operation is to promote, this method returns the ValueType to promote to.

For types supported by the target, this is an identity function. For types that must be promoted to larger types, this returns the larger type to pro

Return an UNDEF node. UNDEF does not have a useful SDLoc.

Return the minimum clearance before an instruction that reads an unused register. For example, AVX instructions may copy part of a register operand i

Return true if unique basic block section names must be generated.

This function returns 0 if the condition is always false if an operand is a NaN, 1 if the condition is always true if the operand is a NaN, and 2 if t

This constructs a pointer to an object of the specified type in the default address space (address space zero).

For example, EQ->EQ, SLE->ULE, UGT->UGT, etc. @returns the predicate that would be the result if the operand were regarded as unsigned. Return the uns

For example, SLT->ULT, SLE->ULE, SGT->UGT, SGE->UGE, ULT->Failed assert @returns the unsigned version of the predicate for this instruction (which has
