Summary: Pull Request resolved: https://github.com/pytorch/pytorch/pull/29143 THP_CORE macro is a very old macro that appeared to have served two purposes: 1. The torch-python equivalent of CAFFE2_BUILD_MAIN_LIB, to toggle symbol visibility headers 2. Some sort of ad hoc way of hiding certain definitions from headers so external clients can't get at them. It did (2) in a very confusing manner, because we set THP_CORE in both torch and torch-python (it shouldn't do anything in torch). In this PR I just get rid of use case (2) entirely (so everything shows up in headers all the time), and then redo (1) using a new THP_BUILD_MAIN_LIB macro. This cleans up some of the macro definitions and makes my life easier for working on #27215. Signed-off-by: Edward Z.
