My reverse bisect tells me that LLVM commit d17c54d17de2 ("[llvm-ar] Prevent automatic conversion from thin to full archive") in LLVM 15 resolves this problem. It appears that prior to that change, 'llvm-ar m' without 'T' will change the archive type to full. The following diff resolves this problem for me with no additional failures on LLVM 14 and 16. Masahiro, is this an acceptable change to squash in to 6676e2cdd7c339d?
