Compiling ecocode.cpp with latest clang in Xcode8 incredibly slow #28

Closed cuddlestmonkey closed 5 years ago

I realise this is not a bug with Jerry itself but thought it worth recording in case anyone else hits the issue.

Compiling current release 3.0.6 with latest Qt 5.7 and Xcode 8 on OSX, all is well (barring the odd compiler warning) except when it comes to ecocode.cpp. This sends clang into a long think.

If I chop the static QMap definition down to 100 lines or so it compiles ok, but the compilation time seems to be geometric as the line count grows.

interesting and thanks for reporting. Unfortunately I cannot look into that - my build chain uses the (ancient) Xcode 4.6.3 with Qt 5.6, where this bug does not occur. My machine is too old to run a more recent version of macOS and Xcode (and in any event, I prefer to build on older systems to ensure maximum compatibility)

I've filed a bug report here https://bugreports.qt.io/browse/QTBUG-57672

(not sure where the appropriate place is, Apple, since they apparently use a custom version of clang, Qt, since it happens with QMap, or clang).

If you happen to have the time - does the the behavior happen in general with initializer lists (e.g. with std::map), or just with QMap?

Due to a lack Apple hardware, I will no longer create builds for macOS or support macOS in any way. Previous builds were done on a hacked virtual machine running Mountain Lion, but dev tools are now so old that I cannot use current builds of Qt anymore. Hence this longstanding bug is closed.
