...worklist. I could match the pattern on A, but the problem remains: when D gets modified, A do not get added back tot he worklist. I also considered ding several round of DAGCombine, but it is very easy to run into infinite loops, even with a fair amount of sanity checks. 2017-05-22 7:30 GMT-07:00 Nirav Davé <niravd at google.com>: > This is a little hard to diagnose in the abstract, but it sounds like > you're having a loop along the lines of visit A -> visit B/C -> visit D -> > visit A and that at each step you're making a real reasonable change to the > DAG a...

I have not been able to find any programs for running vector autoregressions with R. I am interested in running Bayesian VARs and also running VARs that run all combinations of variables in the vector. Is anyone currently developing this? -Nirav Mehta

...X86/xray-attribute-instrumentation.ll What test case are you using? In any case, the issue appears to be that llvm doesn't realize that the target address is resolved and erroneously applies branch relaxation to the jump. I don't know why a linker private symbol would make a difference. -Nirav On Wed, Jun 22, 2016 at 12:14 PM, Dean Michael Berris <dberris at google.com> wrote: > On Wed, Jun 22, 2016 at 6:05 AM Nirav Davé <niravd at google.com> wrote: > >> This appears to work: >> >> auto Target = OutContext.createLinkerPrivateTempSymbol(); >>...

...VM v3.4; but changes between v5.0 and v6.0 have introduced this DAG reduction dependency loop. Is there any advice to Out-of-Tree implementations about how to re-write their lowering code for shuffle so as to avoid this kind of infinite dependency coupling?

Martin: It sounds like you are doing is more akin to shuffle selection than fusion and therefore it's a better fit for instruction selection than DAGCombining. Try movign it to <Target>ISelDAGToDAG's Select (or potentially PreprocessISelDAG). Th -Nirav On Tue, Mar 6, 2018 at 4:05 PM Martin J.

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.

Thanks Nirav, I can confirm that this works when I do the compile with llc, but then when linking to an executable with clang (patched with http://reviews.llvm.org/D20352 and compiler-rt patched with http://reviews.llvm.org/D21612) on Linux, I'm getting something different. Here's a sample of the trans...

...entire register. I suspect it'd be possible to define a 1-bit subregister of eflags and mark the various carry-in ops as only using that. Might be worthwhile doing that, separately, even if fixing #1 makes this particular issue disappear for this test case.

...them up in legalization. You should be able to disable this pass universally by overriding mergeStoresAfterLegalization() or conditionally for cases that shouldn't match with canMergeStoresTo.

Hi LLVM-Devs, I am in the process of updating our out-of-tree implementation from v5.0 to v6.0 RC3, and while it builds and mostly runs, I am having trouble with a small number of tests where the 'WorklistMap' in 'DAGCombiner::Run' never becomes empty. This is resulting in a runaway state of continuous heap allocation until the process exhausts all system memory. But I can't

Hmm. This looks like the backend conservatively giving up early on merging. It looks like you're running clang 5.02. There have been some improvements to the backend's memory aliasing and store merging that have landed since. Can you check if this is fixed in a newer version? -Nirav On Tue, Sep 11, 2018 at 2:21 PM, Andres Freund <andres at anarazel.de> wrote: > Hi, > > On 2018-09-11 11:16:25 -0400, Nirav Davé wrote: > > Andres: > > > > FWIW, codegen will do the merge if you turn on global alias analysis for > it > > "-combiner-...

I have a bit of a riddle: In http://reviews.llvm.org/D19904 I'm trying to spell the following assembly: .palign 2, 0x90 jmp +0x9 nopw 512(%rax,%rax,1) // rest of the code I try the following snippet to accomplish this: OutStreamer->EmitLabel(CurSled); OutStreamer->EmitCodeAlignment(4); auto Target = OutContext.createLinkerPrivateTempSymbol(); // Use a two-byte `jmp`.

...p instruction to bypass the relaxation, so that fixes my immediate problem. The question still stands though whether it should be possible to do through the instruction builder interface.
