Description aryeh.friedman 2019-07-29 08:21:53 UTC 
Using default settings for make (and/or portmaster) cmake goes into an infinite loop on task 1 (running the port configuration script).   Sorry don't have a log showing where it went off the rails I just have a lot of iterations of step 0/1

This is a brand new ryzen 5 2600 machine with the kernel reporting 12 cores (6 real ones with 2 threads each).   To repeat:

[with no ports installed]

svn co svn://svn.freebsd.org/ports/head /usr/ports
cd /usr/ports/ports-mgmt/portmaster
make install
cd /usr/ports
rehash
portmaster -d x11/nvdia-driver
...
lots of output
...
devel/llvm infinite loop

oops devel/llvm80 not devel/llvm fails

I had the same problem once: the clock on my system wasn't correct.
Comment 3 aryeh.friedman 2019-07-29 09:00:22 UTC 
This might be ninja related since the build for graphics/jpeg-turbo went into a similar loop (but gave up after 100 tries)

Not in my case it is correct (set it with ntpdate before I started the port installs):

root@neomarx:/usr/ports/distfiles # date
Mon Jul 29 05:01:15 EDT 2019
root@neomarx:/usr/ports/distfiles # ntpdate pool.ntp.org
29 Jul 05:01:52 ntpdate[563]: adjust time server 108.59.2.24 offset -0.297128 sec

It is for sure related to ninja since I have now had 5 or 6 ports in the xfce4 chain die on the same type of loop with the only commonality between them is they use ninja as their build system... is a default of j 12 on make on a fast processor too fast for ninja?

AFACT this isn't an LLVM issue, but rather a ninja issue.
Comment 7 Brooks Davis freebsd_committer freebsd_triage 2020-01-03 22:19:33 UTC 
There may be a bug here, but I've seen zero other reports and I regularly build llvm with -j32.  Closing this since there isn't anything we can work with.
