[LLVMdev] prevent frontend from emitting i64
Generally legalize at IR level is not a good idea.
But if you need legalization on IR code, you can check PNaCl project.
https://chromium.googlesource.com/native_client/pnacl-llvm/
The pass is located at: lib/Transforms/NaCl/ExpandLargeIntegers.cpp
You need make some change, as the pass split large integer into 64bit
integers.

[LLVMdev] prevent frontend from emitting i64
Is it just an optimization pass? Maybe I can cancel it somehow with a flag or by doing some code editing? Can you point me to which passes may do that?
I'm working on editing a backend that can't work with anything larger than 32 bits. Does the legalize stage work on IR code? Maybe i can use that?
