Functions | |
std::vector< uint64_t > | llvm::codelayout::computeExtTspLayout (ArrayRef< uint64_t > NodeSizes, ArrayRef< uint64_t > NodeCounts, ArrayRef< EdgeCount > EdgeCounts) |
Find a layout of nodes (basic blocks) of a given CFG optimizing jump locality and thus processor I-cache utilization. | |
double | llvm::codelayout::calcExtTspScore (ArrayRef< uint64_t > Order, ArrayRef< uint64_t > NodeSizes, ArrayRef< uint64_t > NodeCounts, ArrayRef< EdgeCount > EdgeCounts) |
Estimate the "quality" of a given node order in CFG. | |
double | llvm::codelayout::calcExtTspScore (ArrayRef< uint64_t > NodeSizes, ArrayRef< uint64_t > NodeCounts, ArrayRef< EdgeCount > EdgeCounts) |
Estimate the "quality" of the current node order in CFG. | |
std::vector< uint64_t > | llvm::codelayout::computeCacheDirectedLayout (ArrayRef< uint64_t > FuncSizes, ArrayRef< uint64_t > FuncCounts, ArrayRef< EdgeCount > CallCounts, ArrayRef< uint64_t > CallOffsets) |
Apply a Cache-Directed Sort for functions represented by a call graph. | |
std::vector< uint64_t > | llvm::codelayout::computeCacheDirectedLayout (const CDSortConfig &Config, ArrayRef< uint64_t > FuncSizes, ArrayRef< uint64_t > FuncCounts, ArrayRef< EdgeCount > CallCounts, ArrayRef< uint64_t > CallOffsets) |
Apply a Cache-Directed Sort with a custom config. | |
