Hi All,
After rebasing (my MTU patchset) to bpf-next (232164e041e925a) I'm
getting this error when compiling selftests (full error below signature):
"CLNG-BPF [test_maps] atomics.o"
"fatal error: error in backend: line 27: Invalid usage of the XADD return value"
"PLEASE submit a bug report to https://bugs.llvm.org/ [...]"
It looked like a LLVM bug, so I compiled llvm-11.1.0-rc1, but it still fails.
I noticed Brendan Jackman changes... could this be related?

Yes, since bpf-next commit 98d666d05a1d970 ("bpf: Add tests for new
BPF atomic operations") you need llvm-project commit 286daafd6512 (was
https://reviews.llvm.org/D72184) for the selftests, which will be in
Clang 12. You'll need to build LLVM from master.

I ran into this as well, so a (shameless) plug: for folks running
Debian derivatives, there's https://apt.llvm.org/ where you can get
daily Clang snapshot builds.

I'm compiling from LLVM 'main' branch (commit e6d758de82b6) but it
unfortunately fails to compile (see error below).
Any recommended LLVM commit id that works?

I got compiling to work on this commit. But the error below, were
likely caused by my compile machine simply ran out of memory (it "only"
have 16GB RAM).
I reduced the number of parallel jobs (ninja -j6) and have now
successfully compiled devel branch of LLVM.
Now the compile of BPF-selftests is possible again.
