[llvm-dev] Can LLVM optimize for a stack machine backend?

[Quentin Colombet via llvm-dev]

Hi Xiaohui,

I think the situation didn’t really change with respect to what you found.
In particular I believe the advice from Chris that you already found (https://lists.llvm.org/pipermail/llvm-dev/2008-November/018626.html <https://lists.llvm.org/pipermail/llvm-dev/2008-November/018626.html>) is the best thing you can do right now.

Cheers,
-Quentin

I have seen several attempts to use it for a stack machine backend, such as this <https://lists.llvm.org/pipermail/llvm-dev/2009-February/020335.html>, this <https://lists.llvm.org/pipermail/llvm-dev/2008-November/018626.html>, and this <https://lists.llvm.org/pipermail/llvm-dev/2006-August/006460.html>. What is the state of the art of using LLVM to optimize for a stack machine? Or LLVM is not a good choice for this job?
