I tried with cbind function but failed, as it only works when two data

[LLVMdev] Question about dag-combine pass
...ion, it's converted to store/load(sext) during
dag-combining,
not legalization. and also, I found that the dag-combining is different for
each architecture.
Q1. where is the correct place in the source code that the truncate
operation is gone during the dag combining pass.
Q2. Why that the dag-combinig is different for each architecture.
Q3. I don't want to use that kind of store/load techiniq to mimic
truncation, but just replace to some instruction such as
'CONVERT_i32_to_i8'. What is good way to do?
Thanks,
Jiin
