Veverak (Dec 03 2021 at 13:05): Veverak (Dec 03 2021 at 13:05):cranelift_frontend::FunctionBuilder::emit_small_memory_copy(documentation) takes the arguments dest_align and src_align, which it uses only for an assertion and then ignores. It chooses an access size which may be larger than the alignment and calls flags.set_aligned(); and proceeds to doing unaligned memory access. This seems to be a mistake.
bjorn3 (Dec 03 2021 at 13:10):Can you open an issue?
Veverak (Dec 03 2021 at 13:17):I don't have a Github account, so unfortunately that excludes me from the issue tracker. I might create an account that I use only to contribute to Cranelift, but I'm very reluctant after all the bad news about Github.
bjorn3 (Dec 03 2021 at 13:35):No problem. Can I create an issue and copy paste your message?
Veverak (Dec 03 2021 at 13:52):Of course you can. Thank you.
