Debug var, expr and loc were only supported for non-fixed stack objects. This patch adds the following fields to the "fixedStack:" entries, and renames the ones from "stack:" to: * debug-info-variable * debug-info-expression * debug-info-location Differential Revision: https://reviews.llvm.org/D46032 llvm-svn: 330859
