Subject: Improve performance of the QML front-end
X-Git-Url: http://git.silmor.de/gitweb/?a=commitdiff_plain;h=c742d2d12122e752a74da3e3f26dff28ff967b9d;p=konrad%2Fqtdeclarative.git

Improve performance of the QML front-end

Introduced a new lexer and a more efficient representation of
the AST. Instead of creating unique name ids, we simply use
QStringRef(s).
