[LLVMdev] LLVM Backwards-Compatability

[Eric Cheng]

Hi,

I understand that backend support for Alpha was taken out a few years back,
but I was wondering if anyone was aware of a workaround for the following
use case: I would like to be able to generate Alpha binaries, but I have
transforms that were written using the structure of the latest release
(3.3).

I have tried generating IR using r3.3, and understandably, neither the
static compiler or disassembler from r2.9 supports the newer revision
format. Is there already a tool available that allows for this type of
backwards compatibility either through IR translation or some other means?

Thanks for your help,
Eric
