# Note: is uses some of the same facilities that the user API depends on,
# we use a linker script to ensure that the shared library only exposes the
# symbols the compiler needs.
#
# This is currently done as a shared library to make it suitable for being
# loaded by mlir::ExecutionEngine. In e.g. an embedded scenario, we would
# need to create a static library and link that into the binary.
