Summary
This build attempts to cross-compile the go-sqlite3's _example/simple Go project from a
linux/amd64host to anopenbsd/arm64target. However, clang appears to crash on the generated generated_cgo-exports.catRunning pass 'Post-RA pseudo instruction expansion pass' on function '@callbackTrampoline'.It wasn't clear to me if this is a Go issue or an LLVM issue, but I figured I'd start here since the toolchain asked :). Thank you!
