Generating C executable that accesses the shared object file without Python

[tzunghanjuang]

Context:

• Add debug.compiler_functions.compile_cmain to compiler a c main wrapper into an executable.
• (Mainly for testing) Add debug.compiler_functions.run_cmain_executable to run the generate executable with the shared object from MLIR/LLVM.
• Support multi-dimensional arrays in c generation.

Changes

compile_cmain(fn: QJIT, *args) -> str, str takes a qjit decorated function and arguments for that function. It returns a string of LD_LIBRARY_PATH and the path to the output binary file.

run_cmain_executable(ld_env: str, binary_file: str) -> str takes a string of LD_LIBRARY_PATH and the path to the output binary file. The return is a string containing stdout. Users can use debug.print_memref to make values appear there.

@qjit
def f(x):
    y = x*x
    debug.print_memref(y)
    return y
f(5)
>>> MemRef: base@ = 0x64fc9dd5ffc0 rank = 0 offset = 0 sizes = [] strides = [] data =
25
25

ld_env, binary = compile_cmain(f, 1)
result = run_cmain_executable(ld_env, binary)
result.stdout
>>> MemRef: base@ = 0x5df35987b780 rank = 0 offset = 0 sizes = [] strides = [] data =
25
