            Status: NEW
          Severity: normal
          Priority: P2

Duncan's patch 51314 regressed WebKit performance by ~5%. I've reverted it for
now 51397.

This probably means there were llvm optimizer deficiencies that was covered up
by running the gcc inliner. We need to identify and fix them.
