Hi Adrian,
We've made tools/perf/check-headers.sh the mechanism to check
for drift on kernel file copies we have in tools/, and it assumes that
if we have tools/a/b/c/d, then it came from a/b/c/d in the kernel
sources, e.g. a copy of the kernel's arch/x86/lib/x86-opcode-map.txt
would be in tools/arch/x86/lib/x86-opcode-map.txt.
That is not the case with the intel-pt-decoder, so I'm thinking
about moving those files to comply with the model used for other copies,
as having it in util/intel-pt-decoder/ isn't strictly required, i.e.
those files could conceivably be used for other purposes besides
decoding intel-pt traces, say for disassembly/annotate, that albeit not
planned (at least by me) for the near future, would be something
interesting to investigate doing.
IIRC Ingo was the one to point me out this, and now I saw the
warning about it being different flying by in the middle of the build,
differently from what is done by check-headers.sh, that is to show
everything that drifted in one single block, at the start of the build.
So unless you have a strong objection to this, I'll continue
investigation about how do do it with tools/perf/check-headers.sh,
Thanks,
- Arnaldo
P.S: See how the check-headers.sh stand out at the start and how the
intel-pt-decoder copies get buried in the middle:

I have no objection but currently it is (theoretically) possible to compile
Intel PT decoding support into perf script and perf report for any
architecture. i.e. decoding Intel PT from a perf.data file does not depend
on the build architecture.

Right, being on the tools/arch/ will not preclude it from being built
and linked in the other arches, I'll make sure it continues being built
there as well.
