class VPBasicBlock

Declaration

class VPBasicBlock : public VPBlockBase { /* full declaration omitted */ };

Description

VPBasicBlock serves as the leaf of the Hierarchical Control-Flow Graph. It holds a sequence of zero or more VPRecipe's each representing a sequence of output IR instructions. All PHI-like recipes must come before any non-PHI recipes.

Declared at: llvm/lib/Transforms/Vectorize/VPlan.h:2078

Parameters

llvm::VPRecipeBase* Recipe
llvm::VPBasicBlock::iterator InsertPt

bool isExiting() const

Description
