Provide the LLVM as a compiler backend #73

Closed drhagen closed 2 months ago

drhagen commented 2 months ago

This uses llvmlite to build LLVM code from the Tensora IR. Use of the LLVM backend is controlled with the tensora.compile.BackendCompiler.{llvm,cffi} flag to TensorMethod. This is also exposed as the -l llvm option to the CLI, which prints out LLVM IR.

llvmlite has a ctypes interface, but this PR still uses cffi for the taco tensor structures and invoking the compiled function.

Implements #66.
