%global _description %{expand:
|
|
llvmlite provides a Python binding to LLVM for use in Numba.
|
|
|
|
Numba previously relied on llvmpy. While llvmpy exposed large parts of the
|
|
LLVM C++ API for direct calls into the LLVM library, llvmlite takes an entirely
|
|
different approach. Llvmlite starts from the needs of a JIT compiler and splits
|
|
them into two decoupled tasks:
|
|
|
|
- Construction of a Module, function by function, Instruction by instruction.
|
|
- Compilation and optimization of the module into machine code.
|
|
|
|
The construction of an LLVM module does not call the LLVM C++ API. Rather, it
|
|
constructs the LLVM intermediate representation (IR) in pure Python. This is
|
|
the role of the IR layer.
|
|
|
|
The compilation of an LLVM module takes the IR in textual form and feeds it
|
|
into LLVM's parsing API. It then returns a thin wrapper around LLVM's C++
|
|
module object. This is the role of the binding layer.
|
|
|
|
Once parsed, the module's source code cannot be modified, which loses the
|
|
flexibility of the direct mapping of C++ APIs into Python that was provided by
|
|
llvmpy but saves a great deal of maintenance.}
