std::unique_ptr< llvm::Module > | mlir::translateModuleToLLVMIR (Operation *, llvm::LLVMContext &, StringRef) |
Implementation class for module translation.
Holds a reference to the module being translated, and the mappings between the original and the translated functions, basic blocks and values. It is practically easier to hold these mappings in one class since the conversion of control flow operations needs to look up block and function mappings.
Definition at line 55 of file ModuleTranslation.h.
LogicalResult ModuleTranslation::convertBlock | ( | Block & | bb, |
bool | ignoreArguments, | ||
llvm::IRBuilderBase & | builder | ||
) |
Translates the contents of the given block to LLVM IR using this translator.
Convert block to LLVM IR.
The LLVM IR basic block corresponding to the given block is expected to exist in the mapping of this translator. Uses builder
to translate the IR, leaving it at the end of the block. If ignoreArguments
is set, does not produce PHI nodes for the block arguments. Otherwise, the PHI nodes are constructed for block arguments but are not connected to the predecessors that may not exist yet.
Unless ignoreArguments
is set, emit PHI nodes to define values corresponding to the MLIR block arguments. These nodes are not connected to the source basic blocks, which may not exist yet. Uses builder
to construct the LLVM IR. Expects the LLVM IR basic block to have been created for bb
and included in the block mapping. Inserts new instructions at the end of the block and leaves builder
in a state suitable for further insertion into the end of the block.
