Re: [PATCH v6 0/7] Add AutoFDO and Propeller support for Clang build

Hi Rong,
I tested this series by following the documentation added in the series
using Clang 19 and my standard distribution configuration on an Intel
platform with the combinations of
* AutoFDO
* AutoFDO + ThinLTO
* AutoFDO + Propeller
* AutoFDO + ThinLTO + Propeller
and I noticed no issues (it would be great to see create_llvm_prof
somewhere in LLVM upstream for ease of access but that's a small
complaint).
I did not do any real benchmarking to see if those combinations were
actually quicker but I think it is pretty clear from the cover letter
that any sort of gains are going to depend on the profiling and test
case so for time's sake, I did not bother.
