Return true if this shuffle returns a vector with a greater number of elements than its source vectors. Example: shufflevector <2 x n> A, <2 x n> B, <

Convert a non-negative frame index to a stack slot register value.

Convert a 0-based index to a virtual register number. This is the inverse operation of VirtReg2IndexFunctor below.

M6809/M6309 indexed mode handler

M6800/1/2/3 indexed mode handler

Use this to iterate over the valid attribute indexes.

(re-)initializes and clears the set.

Initialize and clear the set.

Compute the registers that are live across this Candidate. Used by targets that need this information for cost model calculation. If a target does not

Copy an existing live thru pressure result.

Perform initialization before packetizing an instruction. This function is supposed to be overrided by the target dependent packetizer.

Optionally override the per-region scheduling policy.

Initialize the stack protector descriptor structure for a new basic block.

Initialize available analysis information.

Perform necessary initialization to handle a subset of CSRs explicitly via copies. This function is called at the beginning of instruction selection.

Replace a StackProbe stub (if any) with the actual probe code inline

Mark the \p Pair.LaneMask lanes of \p Pair.Reg as live. Returns the previously live lanes of \p Pair.Reg.

Insert \p MI in the just before ::getPoint()

If I is bundled then insert MI into the instruction list after the end of the bundle, otherwise insert MI immediately after I.

Insert branch code into the end of the specified MachineBasicBlock. The operands to this method are the same as those returned by analyzeBranch. This

Insert explicit copies in entry and exit blocks. We copy a subset of CSRs to virtual registers in the entry block, and copy them back to physical regi

Insert an unconditional indirect branch at the end of \p MBB to \p NewDestBB. Optionally, insert the clobbered register restoring in \p RestoreBB. \p

Add the given MachineBasicBlock into the maps. If it contains any instructions then they must already be in the maps. This is used after a block has b

Insert a call to an outlined function into the program. Returns an iterator to the spot where we inserted the call. This must be implemented by the ta

Insert a select instruction into MBB before I that will copy TrueReg to DstReg when Cond is true, and FalseReg to DstReg when Cond is false. This fun

Get the instruction count recorded for this function.

Given two sets of AAMDNodes that apply to the same pointer, give the best AAMDNodes that are compatible with both (i.e. a set of nodes whose allowable
