dev-qt/qtscript-5.6.0 can not be compiled because of error: undefined reference to 'cti_vm_throw'. I tried to investigate it a little further but no success. PC ~ # grep -r cti_vm_throw /usr/lib64/ grep: /usr/lib64/libQt5Designer.so.5.5: no such file or directory grep: /usr/lib64/libQt5DesignerComponents.so.5.5: no such file or directory grep: /usr/lib64/libQt5DesignerComponents.so.5.5.1: no such file or directory grep: /usr/lib64/libQt5Designer.so.5.5.1: no such file or directory Let me tell you that from all dev-qt/qt*:5 packages that was to be emerged, qtscript was the first (but not the only one) to fail at compilation. qtcore:5, qtgui:5 etc were built fine with the same {X}FLAGS and toolchain.

Add __attribute__((used)) to the end of cti_vm_throw line in the /var/tmp/portage/dev-qt/qtscript-5.6.0/work/qtscript-opensource-src-5.6.0/src/3rdparty/javascriptcore/JavaScriptCore/jit/JITStubs.h file. Unfortunetly slim LTO build is broken more for qtwebkit-5.5 and 5.6.

I placed at the beggining and it worked. As I recall when I placed at the end it didn't work.
