            Bug ID: 20327
           Summary: lib/CodeGen/CalcSpillWeights.cpp uses a volatile float
           Product: libraries
           Version: trunk
          Hardware: PC
                OS: All
            Status: NEW
          Severity: normal
          Priority: P
         Component: Global Analyses
          Assignee: unassignedbugs at nondot.org

In r206765 I added a volatile float to work around buildbot failures from
hidden precision in x87.

This is a horrible hack and should be removed somehow, ideally by removing the
use of `float` for spill weights entirely.
