Description dewayne 2016-02-08 19:45:53 UTC
I repeatedly failed to perform a buildworld using the latest 10.3Beta from svn due to 
c++: error: no such file or directory: '/usr/obj/prod/100202/P/PRESCOTT/i386.i386/pd3/src/tmp/pd3/src/usr.bin/clang/tblgen/../../../lib/clang/libllvmtablegen/libllvmtablegen.a'
c++: error: no such file or directory: '/usr/obj/prod/100202/P/PRESCOTT/i386.i386/pd3/src/tmp/pd3/src/usr.bin/clang/tblgen/../../../lib/clang/libllvmsupport/libllvmsupport.a'

I commented out SUBDIR_PARALLEL= in src/lib/clang/Makefile which was successful but it made the build horrendously slow. Re-ordering the sequence fixed the problem and returned to a speedy build.

Yes, libllvmtablegen also caused a problem.  One build job was, also, trying to use it before it was built...
