\returns True if instruction \p I can be truncated to a smaller bitwidth for vectorization factor \p VF.

Returns true if the target machine supports all of the reduction variables found for the given VF.

This function is partially responsible for generating the control flow depicted in https://llvm.org/docs/Vectorizers.html#epilogue-vectorization.

Override this function to handle the more complex control flow around the three loops.

Adds the generated MemCheckBlock before \p LoopVectorPreHeader and adjusts the branches to branch to the vector preheader or \p Bypass, depending on t

Adds the generated SCEVCheckBlock before \p LoopVectorPreHeader and adjusts the branches to branch to the vector preheader or \p Bypass, depending on

** open parts that may cause memory-allocation errors */

Returns a range containing only operands needing to be extracted.

Fix up external users of the induction variable. At this point, we are in LCSSA form, with all external PHIs that use the IV having one input value, c

** __gc tag method: calls library's `ll_unloadlib' function with the lib ** handle */

Get the interleaved access group that \p Instr belongs to.

Return the vectorization cost for the given instruction \p I and vector width \p VF.
