Subject: [CFLAA] Remove tautological comparison
X-Git-Url: http://plrg.eecs.uci.edu/git/?a=commitdiff_plain;h=41b6e327f7dedfb9d3020f60f6c6804efeb75b16;p=oota-llvm.git

[CFLAA] Remove tautological comparison

Fixes this (the warning is right, the unsigned value is not negative):
lib/Analysis/StratifiedSets.h:689:53: warning: comparison of unsigned expression >= 0 is always true [-Wtautological-compare]
  bool inbounds(StratifiedIndex N) const { return N >= 0 && N < Links.size(); }
