[PATCH] D73985: [bpf] zero extension is required in BPF implementaiton so remove <<=32 >>=32

[Yonghong Song via Phabricator via llvm-commits]

yonghong-song added a comment.

@jrfastab I added isTruncateFree() callback in BPF IR Lowering (isel) phase. See https://reviews.llvm.org/D74101. This should help with the case where packet data/data_end is truncated with 32bit MOV.
