Hi, Thanks for your patch, Huang. It looks good to me. Just one comment: can you write a testcase, similar to the others used for linker script testing, with your example? Alternatively, you can modify lld/test/elf/linkerscript/sections-with-wildcards.test to test your case. This will make your patch complete and ready for commit, and will ensure we do not regress on this bug if this code is ever

This would also help on systems that are disk-bound in addition to being network and cpu-bound in that it doesn't have to read every block of the file to send checksums. Option 3: Add an option, maybe --checksum-block-bytes=N, that would tell rsync to only checksym the first N bytes of every block. This would probably be used with a very large --block-size. This would be a hint that the file should have no insertions or deletions of data, but only in-place updates with large blocks, or possibly appended additions. This also would help disk-bound systems....
