OptNoneInstrumentation is part of StandardInstrumentations. It skips functions (or loops) that are marked optnone. The feature of skipping optional passes for optnone functions under NPM is gated on a -enable-npm-optnone flag. Currently it is by default false. That is because we still need to mark all required passes to be required. Otherwise optnone functions will start having incorrect semantics. After that is done in following changes, we can remove the flag and always enable this. Reviewed By: ychen Differential Revision: https://reviews.llvm.org/D83519
This directory contains test cases for individual source features of LLVM. It is designed to make sure that the major components of LLVM support all of the features of LLVM, for very small examples. Entire programs should not go here. Regression tests for individual bug fixes should go into the test/Regression dir.
