Subject: Add PostDominatorTree::getDescendants.
X-Git-Url: http://plrg.eecs.uci.edu/git/?a=commitdiff_plain;h=4e37ce82aaf13385e3113a7e7a68c0b97ef0078b;p=oota-llvm.git

Add PostDominatorTree::getDescendants.

This patch adds the counter-part to DominatorTree::getDescendants.
It also fixes a couple of comments I noticed out of date in the
DominatorTree class.
