Refactor the perf python module build to instead of building C files
it links libraries. To support this make static libraries for tests,
ui, util and pmu-events. Doing this allows fewer functions to be
stubbed out, importantly parse_events is no longer stubbed out which
will improve the ability to work with heterogeneous cores.
Patches 1 to 5 add static libraries for existing parts of the perf
build.
Patch 6 adds the python build using libraries rather than C source
files.
Patch 7 cleans up the python dependencies and removes the no longer
needed python-ext-sources.
Ian Rogers (7):
perf ui: Make ui its own library
perf pmu-events: Make pmu-events a library
perf test: Make tests its own library
perf bench: Make bench its own library
perf util: Make util its own library
perf python: Switch module to linking libraries from building source
perf python: Clean up build dependencies

Make the ui code its own library. This is done to avoid compiling code
twice, once for the perf tool and once for the perf python module.

Make pmu-events into a library so it may be linked against things like
the python module and not built from source.

Make the benchmark code into a library so it may be linked against
things like the python module to avoid compiling code twice.

Make the util directory into its own library. This is done to avoid
compiling code twice, once for the perf tool and once for the perf
python module. For convenience:
arch/common.c
scripts/perl/Perf-Trace-Util/Context.c
scripts/python/Perf-Trace-Util/Context.c
are made part of this library.

setup.py was building most perf sources causing setup.py to mimic the
Makefile logic as well as flex/bison code to be stubbed out, due to
complexity building. By using libraries fewer functions are stubbed
out, the build is faster and the Makefile logic is reused which should
simplify updating. The libraries are passed through LDFLAGS to avoid
complexity in python.
Force the -fPIC flag for libbpf.a to ensure it is suitable for linking
into the perf python module.

The python build now depends on libraries and doesn't use
python-ext-sources except for the util/python.c dependency. Switch to
just directly depending on that file and util/setup.py. This allows
the removal of python-ext-sources.

It does require a clean build to avoid some -fPIC errors presumably
because not everything that requires it gets rebuilt, for anyone who
gets stuck on that.

We need to find a way to avoid requiring the 'make clean' :-/

Do we need to make it so that if any of the Makefiles are touched it
does a clean? I'm assuming that was the cause of the issue I experienced
here and that the Makefile and/or Build files aren't mentioned as
dependencies of any target.

Perhaps we can do something with the FEATURE_DUMP. It'd be nice to
detect build argument changes and rebuild when that occurs. I'm used
to doing lots of `make clean` due to sanitizer builds, something we
should probably capture through features and/or `perf version
--build-options`. Anyway, out-of-scope for these patches.
I need to cut a v2 due to failing to add the new `.a` files to the clean target.
Thanks for the review,
Ian
