(In reply to Wen Heping from comment #4)
Thank-you Wen Heping.  I had some challenges because I hadn't yet moved to git
and our portrevision was 1 not 3.  Regardless, on FreeBSD 12.2Stable and
building with gcc10 (gcc-10.2.0), I have 
# swipl -g version.
Welcome to SWI-Prolog (threaded, 32 bits, version 8.4.0)
and
# swipl -g version
Welcome to SWI-Prolog (threaded, 64 bits, version 8.4.0)

We build most of our ports using gcc, because that's what most developers use.

As an FYI, we take advantage of FreeBSD's implementation of ASLR on production
systems where SWI-PL 8.4.0 is now installed, we also build with O3 and LDFLAGS=
-Wl,--strip-debug -Wl,--build-id=md5 -Wl,--hash-style=sysv -pie -Wl,-z,notext
-z notext -z relro -z now -Wl,-rpath=/usr/local/lib/gcc10
-L/usr/local/lib/gcc10

swi-pl passed our tests which includes "extras" like threads, clpfd, external
tables, yaml and now redis :) 

-------------  As an FYI, ...
We attempted to build using clang, but retained the gcc CFLAGS, some of which
don't work with clang.  

On i386 with clang 10.0.1 fails with:

=========== The following were my initial build attempts where I had these
problems, which are probably of my own doing (because I hadn't moved to
portrevision=3

After some minor changes, we're very happy and I'm glad that it works. 
Thank-you.
