getTopMemDGNode()

MemDGNode * llvm::sandboxir::MemDGNodeIntervalBuilder::getTopMemDGNode ( const Interval< Instruction > &  Intvl, const DependencyGraph &  DAG  )

static

Scans the instruction chain in Intvl top-down, returning the top-most MemDGNode, or nullptr.

make()

Interval< MemDGNode > llvm::sandboxir::MemDGNodeIntervalBuilder::make ( const Interval< Instruction > &  Instrs, DependencyGraph &  DAG  )

static

Given Instrs it finds their closest mem nodes in the interval and returns the corresponding mem range.

Note: BotN (or its neighboring mem node) is included in the range.
