Hello,
The gollvm build with LLVM tip is currently broken; there have been some
upstream LLVM changes that aren't compatible with the Gollvm bridge code
(notably the opaque pointer migration), which causes build failures. This
is a known problem, I haven't had enough free time to fix it recently.
I suggest building with slightly older versions of the LLVM and related
repos. For example, this should work:
gollvm commit: 3452ec6bebaa1b432aabed1991475f4444c1775e
libbacktrace commit: fd9442f7b5413e7788dfcf356f6261afcedb56e8
libffi commit: 2e825e219fa06d308b9a9863d70320606d67490d
gofrontend commit 1c5bfd57131b68b91d8400bb017f35d416f7aa7b
llvm-project commit 09629215c272f09e3ebde6cc7eac9625d28910ff
Let me know if you have issues building with this setup.
Thanks, Than
