            Bug ID: 24360
           Summary: lld missing linkage to libpthread (required for
                    DragonFly)
           Product: lld
           Version: unspecified
          Hardware: PC
                OS: DragonFly BSD
            Status: NEW
          Severity: normal
          Priority: P
         Component: All Bugs

Created attachment 14691
  --> https://llvm.org/bugs/attachment.cgi?id=14691&action=edit
patch to link libpthread with 5 lld libraries.

Starting with LLVM 3.7, LLD is built by default in FreeBSD ports which
DragonFly uses.  It did not build on DragonFly because the pthread_create
symbols could not be found.

The attached patch was required to get it to build (although I assume the fix
would be in a different form).  As DragonFly uses modern GNU binutils linkers
with their defaults, explicit linking is required on DragonFly.

Consider this a "problem report" the provides an illustratory fix.
