Something has definitely gone wrong on your system, but I'm at a lost a to what it it. Here's what I'd expect to see: $ ls -li /usr/local/bin/*lit*37 /usr/local/llvm37/bin/*lit* 1580744 -r-xr-xr-x 4 root wheel 82 Dec 27 05:29 /usr/local/bin/lit37 1580744 -r-xr-xr-x 4 root wheel 82 Dec 27 05:29 /usr/local/bin/llvm-lit37 1580744 -r-xr-xr-x 4 root wheel 82 Dec 27 05:29 /usr/local/llvm37/bin/lit 1580744 -r-xr-xr-x 4 root wheel 82 Dec 27 05:29 /usr/local/llvm37/bin/ll= vm-lit That being said, I could switch them to symlinks. In general I don't like this as a precedent. I'm definitely not willing to support arbitrary filesystem hierarchies so if we're going to do this, we need some sort of principles for splits that we're willing to support. -- Brooks --cNdxnHkX5QqsyA0e Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQEcBAEBAgAGBQJYiv2QAAoJEKzQXbSebgfAGeUIAJGdQ8jJV2JW1EK7yuWndFhi d3IVrOGrg8YdkLpcybyldbgXeKwQJJR2vwaL9WgpPJzgSssWDcSUFSoPIbOmrNLe AkUhQzs0GnA1tB7J+l53QlkamI+HeOyEEBbke6yXY3AQHjR4u+OHHf36WDEVoc24 wdyTdOHkoTpFjvdi07Q0GrU1BNLqoQrji5yYZY+XiBo1+YRXljCCkA99WvlOZdTn Sl1rx3EAc9qIlyPgEOBMbYvjz8kAsyli75+CVlRX6MHbc82JbumHxMzJ7K7CDe1Z Cpm121WD954Sm8ISxW+05cIq2uaNftQxQZV+u39uftp9zv4WzRTL96ryt1Vkh2A= =vAPE -----END PGP SIGNATURE----- --cNdxnHkX5QqsyA0e--
