Subject: Use removeDups to find top-level duplicate names
X-Git-Url: http://git.megacz.com/?a=commitdiff_plain;h=116134b1319e60ff38fc3710bd764cff34554837;hp=116134b1319e60ff38fc3710bd764cff34554837;p=ghc-hetmet.git

Use removeDups to find top-level duplicate names
findDupsEq is quadratic, whereas removeDups is n log n.
Fixes T1969 regression.
