# For perfetto maintainers. Pulls out demangling-related sources out of
|
|
# llvm-project and repackages them as a single tar archive. This works around
|
|
# the fact that gitiles, when generating an on-demand archive, uses a current
|
|
# timestamp, so the hash of the archive is different every time you fetch.
|
|
|
|
# Usage example:
|
|
# sh tools/repackage_llvm_demangler.sh 3b4c59c156919902c785ce3cbae0eee2ee53064d
|
|
#
|
|
# Then upload the tar with "gsutil cp -n -a public-read ... gs://perfetto/...",
|
|
# and update install-build-deps.
