addBlock()

template<typename PredFn = decltype(includeAllBlocks)>

Error llvm::jitlink::BlockAddressMap::addBlock ( Block &  B, PredFn  Pred = includeAllBlocks  )

inline

Add a block to the map.

Returns an error if the block overlaps with any existing block.

addBlocks()

template<typename BlockPtrRange , typename PredFn = decltype(includeAllBlocks)>

Error llvm::jitlink::BlockAddressMap::addBlocks ( BlockPtrRange &&  Blocks, PredFn  Pred = includeAllBlocks  )

inline

Add a range of blocks to the map.

Returns an error if any block in the range overlaps with any other block in the range, or with any existing block in the map.

Definition at line 1599 of file JITLink.h.

addBlocksWithoutChecking()

template<typename BlockPtrRange >

void llvm::jitlink::BlockAddressMap::addBlocksWithoutChecking ( BlockPtrRange &&  Blocks )

inline

Add a range of blocks to the map without checking for overlap with existing blocks.

The client is responsible for ensuring that the block added does not overlap with any existing block.

addBlockWithoutChecking()

void llvm::jitlink::BlockAddressMap::addBlockWithoutChecking ( Block &  B )

inline

Add a block to the map without checking for overlap with existing blocks.

The client is responsible for ensuring that the block added does not overlap with any existing block.

getBlockAt()

Block * llvm::jitlink::BlockAddressMap::getBlockAt ( orc::ExecutorAddr  Addr ) const

inline

Returns the block starting at the given address, or nullptr if no such block exists.

static bool llvm::jitlink::BlockAddressMap::includeAllBlocks ( const Block &  B )

inlinestatic

A block predicate that always adds all blocks.
