halide-cache: hash the builder invocation#3
Merged
Conversation
Some flags can change the builder output even though the builder inputs and dependencies haven't changed. Make the builder invocation part of the hash generation but make paths relative to the base dir if possible. Several of the strings in the builder invocations aren't paths at all, but they are tolerated since stripping the base_dir from them won't succeed like for relative paths.
