2018-09-27Add Utils.expandPrefixes as Prefix Unique helper (#900)Schuyler Eldridge
This adds a utility, expandPrefixes, that expands a string into all possible prefixes based on a delimiter. Any repeated occurrence of the delimiter is viewed as a contributing to a prefix. E.g., "foo_bar" expands to Seq("foo_", "foo_bar"). This is useful for inlining and keyword mangling on LowForm. You would like to be able to generate a new name that is prefix unique with respect to a namespace. Signed-off-by: Schuyler Eldridge <schuyler.eldridge@ibm.com>
