Hi, Is there a kind of scope mechanism in the instruction lowering pattern language in order to control where instructions are inserted or how they are later reordered during the SelectionDiag linearization? I know the glue chain that stick instructions together. But such mechanism in not provided in instruction lowering pattern. I'm facing many situations where some patterns are lowered into

Hi, I am receiving an LLVM Error from a custom 16-bit backend I am creating. I am having trouble understanding the error/problem and how to go about solving it. The error is: LLVM ERROR: Cannot select: t29: i32,ch = load<LD2[%x.addr], anyext from i16> t14, FrameIndex:i16<0>, undef:i16 t7: i16 = FrameIndex<0> t9: i16 = undef In function: mul_add Can anyone provide any pointers as to what the problem is and potential places I should look to fix it? Thanks and best regards, Mus...

Is there an established way of disabling a DAG combine on a per target basis, where it appears to be detrimental to the generated code? Writing if (!mytarget) in DAGCombiner.cpp works but tends to be erased by git merge and generally doesn't look ideal. Writing the inverse transform in target specific code doesn't work in this instance and in general creates an infinite loop. Guidance

I see we're missing an isel pattern for add producing carry and doing a memory RMW. I'm going to see if adding that helps anything. ~Craig On Mon, Feb 27, 2017 at 8:47 PM, Nirav Davé via llvm-dev < llvm-dev at lists.llvm.org> wrote: > Yes. I'm seeing that as well.

The earlier post had an attached text file that did not go through. I hope this link works. I tested it with a coworker, but that is no guarantee. https://uflorida-my.sharepoint.com/:u:/g/personal/tebert_ufl_edu/EXf5u_CtTwJCrhdfTBIPr7wBefZHx4P_suj4wAWb8i8HFA?e=iQawhh Regards, Tim
