# Function names in the Torch compilation unit are systematic -- they
|
|
# are effectively Python dotted paths. E.g. a Python module "foo" with a class
|
|
# "bar" with a method "baz" will result in a function in the compilation unit
|
|
# called "foo.bar.baz" when it gets `torch.jit.script`'ed.
|
|
# (with the exception that `__main__` is replaced with `__torch__`).
|
|
#
|
|
# Given how systematic this is, we don't treat the symbol names as opaque (i.e.
|
|
# we don't need to capture their names when FileCheck testing).
