Get the cost of using \p ValMapping to decompose a register. This is similar to ::copyCost, except for cases where multiple copy-like operations need

Estimate a cost of Broadcast as an extract and sequence of insert operations.

Return an ISD::BUILD_VECTOR node. The number of elements in VT, which must be a vector type, must match the number of operands in Ops. The operands mu

getBundle - Return the ingoing (Out = false) or outgoing (Out = true) bundle number for basic block #N

Return the index of the last bundle operand in the Use array.

Return the index of the first bundle operand in the Use array.

Retrieve the byref type.

Retrieve the byval type.

Return a new CALLSEQ_END node, which always must have a glue result (to ensure it's not CSE'd). CALLSEQ_END does not have a useful SDLoc.

Return a new CALLSEQ_START node, that starts new call frame, in which InSize bytes are set up inside CALLSEQ_START..CALLSEQ_END sequence and OutSize s

Get index of Calling Convention operand.

Allow the target to override the cost of using a callee-saved register for the first time. Default value of 0 means we will use a callee-saved registe

Returns how many bytes of callee-saved registers the target pushed in the prologue. Only used for debug info.

Return the live range for register unit \p Unit if it has already been computed, or nullptr if it hasn't been computed yet.

Get a cached analysis result or return null.

Return the operand of the underlying instruction associated with @p Arg.

Return the operand index of the underlying instruction associated with @p Arg.

Return the operand index of the underlying instruction associated with the callee of this ACS. Only valid for callback calls!

These methods return the opcode of the frame setup/destroy instructions if they exist (-1 otherwise). Some targets use pseudo instructions in order t

Compute a cost of the given call instruction. Compute the cost of calling function F with return type RetTy and argument types Tys. F might be nullpt

Return a mask of call-preserved registers for the given calling convention on the current function. The mask should include all call-preserved aliases

Get the call site number for a begin label.

Return the pointer to function that is being called.

getCalleeSavedSpillSlots - This method returns a pointer to an array of pairs, that contains an entry for each callee saved register that must be spil

Returns the calling convention

Return the calling convention.

Return the canonical name for a function, taking into account suffix elision policy attributes.

Convenience accessors.

Get the parentPad of this catchret's catchpad's catchswitch. The successor block is implicitly a member of this funclet.

This is the helper function to return the newly negated expression only when the cost is cheaper.

Optional field.

Get the class with the specified name.

Get casted version of extra data. @{

Return the specific clause record wrapped in the Clause class.

Get the value of the clause at index Idx. Use isCatch/isFilter to determine what type of clause this is.

Convenience accessor.

Return the builtin name for the __builtin___clear_cache intrinsic Default is to invoke the clear cache library call

Get the CondCode that's to be used to test the result of the comparison libcall against zero.

Get the column where the common function was defined.

Get the common semantic for two semantics, with the added imposition that saturated padded types retain the padding bit.

Return bitmask of domains that are available and in mask.

The condition block computes whether there is another loop iteration. If yes, branches to the body; otherwise to the exit block.

Return how the condition code should be treated: either it is legal, needs to be expanded to some other code sequence, or the target has a custom expa
