1 # This file holds test cases for the Rust demangler.
2 # Each test case looks like this:
3 # options
4 # input to be demangled
5 # expected output
6 #
7 # See demangle-expected for documentation of supported options.
8 #
9 # A line starting with `#' is ignored.
10 # However, blank lines in this file are NOT ignored.
