Detailed Description

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 58 of file ModuleTranslation.h.

Member Function Documentation

◆ convertBlock()

LogicalResult mlir::LLVM::ModuleTranslation::convertBlock	(	Block &	bb,
		bool	ignoreArguments,
		llvm::IRBuilderBase &	builder
	)

inline

Translates the contents of the given block to LLVM IR using this translator.

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.
