From 1d4e8baa9c7f9dfc14156a762d2cd0016ceca034 Mon Sep 17 00:00:00 2001 From: Reid Kleckner Date: Wed, 28 May 2014 22:49:12 +0000 Subject: Add a simple helper function to create a 64-bit integer. Add a function to combine two 32-bit integers into a 64-bit integer. There are no calls to this function yet, although a subsequent change will add some in LLDB.
