* Fix broken build when LTTng tracing is enabledEirik Aavitsland2021-08-241-0/+10
| | | | | | | | | | | | This change fixes 3c556885f02a93efc34dd439ee9aaea22993a2d6 which was a broken cherry-pick from Qt 6, since it mixed up src/opengl and src/gui/opengl directories. It also cherry-picks 3dcdd89dd158306784159d673a1be76a32036b14 from Qt 6, which fixes the errors in the tracepoints file.

* Don't pass scope args to _exit trace pointsMilian Wolff2019-04-301-1/+1
| | | | | | | | | | | | | | When we trace a scope, then we pass the scope args to the _entry trace point. There is no need to do that also for the _exit trace points, it just blows up the trace data for no obvious gain. Any decent tracing consumer can easily find the args for the _exit call by matching it to its _entry call. Note that this is standard practice in trace points, and also done like this in the Linux Kernel trace points for example.

* Forward declare all types required for compilation with `-trace`Milian Wolff2019-04-051-0/+6
| | | | | | | | | | | | | | | This patch fixes compilation with `-trace lttng` or `-trace etw`. We need to forward declare QEvent, QImageReader etc., otherwise the types will be unknown while compiling the trace points. In order to handle this generically, the tracegen utility is extended to support a 'prefix text' in the `*.tracepoints` input files. Any text within curly braces will be embedded as-is in the generated file. This can then be used to add forward declarations for the types we need, including potential namespaces and such.
