Subject: Don't warn about a null live range if the Value is a ConstantIntegral.
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=eb8863db909e1a8383c849c3de23eefa0a1c23b7;p=oota-llvm.git

Don't warn about a null live range if the Value is a ConstantIntegral.
Otherwise, if you're in debugging mode, you get warnings for (apparently)
every immediate constant in the function during reg. allocation.
