[Qemu-devel] [PATCH 0/2] trace: fix Makefile dependencies

[Stefan Hajnoczi]

Issues with trace/Makefile.objs:

1. Generated code is not recreated when patches modify scripts/tracetool/*.py.
   Typically such patches also modify trace/*.[ch] and the result is build
   failures when new C code compiles against stale generated code.

2. The timestamp mechanism used to avoid unnecessary rebuilding is broken, it
   currently requires two make invocations for a full build.

Stefan Hajnoczi (2):
  trace: fix make foo-timestamp rules
  trace: add make dependencies on tracetool source
