Subject: Mostly undo r123297, but move the default case in EvaluateAsPCRel to the top
X-Git-Url: http://plrg.eecs.uci.edu/git/?a=commitdiff_plain;h=5f8a917b6558f8fdf31b4a6fa591b396e16b9ff2;p=oota-llvm.git

Mostly undo r123297, but move the default case in EvaluateAsPCRel to the top
of the switch block to appease GCC.
