[llvm-dev] Compatibility of .ll file among different versions of LLVM

[Peng Yu via llvm-dev]

Hi,

I am wondering what is the compatibility of .ll file. For example, for
a .ll file generated by an older version of LLVM, can it be guaranteed
to be assembled to a bc file using a newer version of LLVM and run
correctly? Thanks.
