This release includes the following significant enhancements
- Support ARM SPE as input for AutoFDO and Propeller by @dhoekwater
- Various fixes for the
create_gcovtool by @erozenfeld - Various fixes to the build system by @shenhanc78 and @dhoekwater
- Internal improvements to Propeller workflows
This release also makes dependencies part of the repository as git submodules. Note that this will be the last release where AutoFDO and Propeller tooling are bundled in the same repository. In the future the Propeller tooling will be moved to https://github.com/google/llvm-propeller and this repository will only host the AutoFDO tooling.
