New Revision: 5656d7971b395b6303661e2ef7c3e6960c715b2a
URL: https://github.com/llvm/llvm-project/commit/5656d7971b395b6303661e2ef7c3e6960c715b2a
DIFF: https://github.com/llvm/llvm-project/commit/5656d7971b395b6303661e2ef7c3e6960c715b2a.diff
LOG: [llvm][tapi-diff] Transition diff-tool to be more general purpose
This is the first of transition tapi-diff to be readtapi.
This tool will eventually replace functionality for Xcode's `xcrun tapi stubify` and
`xcrun tapi archive`.
This patch updates the tool name and is a minor refactor for the driver to handle more options.
