[PATCH] Another small cleanup to the const_and_copies stack
2015-09-11 Jeff Law <law@redhat.com>
PR tree-optimization/47679
* tree-ssa-dom.c (struct cond_equivalence): Update comment.
* tree-ssa-scopedtables.h (class const_and_copies): Prefix data
member with m_. Update inline member functions as necessary. Add
toplevel comment.
* tree-ssa-scopedtables.c: Update const_and_copies's member
functions to use m_ prefix to access the stack.
