# This tests miscellaneous features of the emitter that are not tested by the
# fill, matmul, convolution, or pooling tests. The features include:
# - constant defined in the body
# - fix/predefined types
# - some math/arith functions, including abs, ceil, exp, floor, log, and negf
# - custom op names.
