[llvm-dev] Error Type set is empty for each HW mode

[Arsen Hakobyan via llvm-dev]

Hi all,

I am trying to understand what is causing the following error to be
generated when building LLVM/Clang on macOS:
------------
Type set is empty for each HW mode:
possible type contradiction in the pattern below (use -print-records with
llvm-tblgen to see all expanded records).
------------

This is generated for the custom Target which uses default hardware mode.
I am using -G Xcode configuration option.
Comparing with Linux build, different
TypeInfer::ValidateOnExit::~ValidateOnExit() are called because of the
NDEBUG flag. I would like to understand why/from where NO DEBUG flag is set
on macOS while building tablegen and why it is not set for linux build.

What kind of issues this checking prevents on macOS which is not essential
for Linux ?

Any thought and suggestions are highly appreciated.

Best Regards,
Arsen
