* scripts/tracetool: Fix dtrace generation for macOSRoman Bolshakov2020-09-091-1/+14
| | | | | | | | | | | | | | | | dtrace USDT is fully supported since OS X 10.6. There are a few peculiarities compared to other dtrace flavors. 1. It doesn't accept empty files. 2. It doesn't recognize bool type but accepts C99 _Bool. 3. It converts int8_t * in probe points to char * in header files and introduces [-Wpointer-sign] warning.

* scripts/tracetool: Update maintainer email addressPhilippe Mathieu-Daudé2020-06-241-1/+1

As I'm not sure this old email is still valid, update it to not produce package with broken maintainer email.

* trace: avoid SystemTap dtrace(1) warnings on empty filesStefan Hajnoczi2019-03-221-0/+5
| | | | | | | | | | | | | | | | | | target/hppa/trace-events only contains disabled events, resulting in a trace-dtrace.dtrace file that says "provider qemu {}". SystemTap's dtrace(1) tool prints a warning when processing this input file. This patch avoids the error by emitting an empty file instead of "provider qemu {}" when there are no enabled trace events.

* trace: introduce a formal group name for trace eventsDaniel P. Berrange2016-10-121-1/+1
| | | | | | | | | | | | | | | | | | | | | | | The declarations in the generated-tracers.h file are assuming there's only ever going to be one instance of this header, as they are not namespaced. When we have one header per event group, if a single source file needs to include multiple sets of trace events, the symbols will all clash. This change thus introduces a '--group NAME' arg to the 'tracetool' program. This will cause all the symbols in the generated header files to be given a unique namespace. If no group is given, the group name 'common' is used, which is suitable for the current usage where there is only one global trace-events file used for code generation.
