The specific case I was researching is in proprietary code, but I can see eBPF verifier/codegen degradations caused by moving from v1 to v3 in many public repos, e.g. try to compile Tracee (https://github.com/aquasecurity/tracee):
```
$ cd tracee/pkg/ebpf/c
$ clang-20 -D__TARGET_ARCH_x86 -I. -I/usr/x86_64-linux-gnu/include -I/lib/modules/`uname -r`/build/include -target bpf -O2 -g -c ./tracee.bpf.c -mcpu=v1 -o /tmp/test-v1.o
$ clang-20 -D__TARGET_ARCH_x86 -I. -I/usr/x86_64-linux-gnu/include -I/lib/modules/`uname -r`/build/include -target bpf -O2 -g -c ./tracee.bpf.c -mcpu=v3 -o /tmp/test-v3.o
$ sudo /root/veristat /tmp/test-v1.o
