Hello, The documentation for llvm-ar says that option 'z' is used to compressed a file before archiving it. I did some tests with different input files (text and LLVM bitcode) and found the archive to be about the same size as the input. When debugging I found that the compressed flag gets passed to several calls and eventually makes it to Archive::writeMember() but this function doesn't do anything with it. Is compression working with llvm-ar? Can someone provide an example of how to use it? My command line looks something like llvm-ar rcz [archive_name] [input_file] Thanks, Javier -------------- next part -------------- An HTML attachment was scrubbed...

Hi, I haven't seen any reply to this. Can someone please point me to the persons maintaining llvm-ar? I can direct my questions to them.
