From 5eea1cdad8a5fa8a96c561248d9dabbc0b848016 Mon Sep 17 00:00:00 2001 From: Colin Walters Date: Wed, 25 Jan 2017 09:25:27 -0500 Subject: lib: Move the bupsplit selftest into our test framework We weren't running it before. Also I switched it to use GLib. Preparation for some oxidation work (having an implementation of bupsplit in Rust). I exported another function to do the raw rollsum operation which is what this test suite uses.
