Mac: Huge performance regression with qmake on bigger subdirs projects

XMLWordPrintable

    • macOS

      Running qmake -r on Qt Creator takes 2m7.559s with Qt 5.1, while it takes "0m36.715s" with Qt 5.0.2. With the qmake parser in Qt Creator itself (i.e. opening Qt Creator in Qt Creator) the penalty is even bigger (~factor 10, ~1m instead of ~6s).

      The results of xcrun and xcodebuild must be cached instead of running these over and over again in the case of subdirs projects.
