Rob, I can reproduce the behaviour you observe using llvm top-of-tree. I will try to look into it.

Hi Rob, > I'm using the gvn pass, not sure about basic-aa. if you are using LLVM from svn then you need to specify the basic-aa analysis, otherwise gvn won't unify calls to readonly/readnone functions.

I'm using the gvn pass, not sure about basic-aa. I've copied the code as-is from http://llvm.org/docs/tutorial/LangImpl4.html#code and added "F->addFnAttr( Attribute::ReadOnly )" after "Function *F = Function::Create(FT, Function::ExternalLinkage, Name, TheModule)". The passes it sets up are: // Set up the optimizer pipeline. Start with registering info about

Hi I'm following the excellent Kaleidoscope tutorial to learn how to build an interpreter using LLVM. Apologize if this list is not the best place to post beginner's questions. In Kaleidoscope 2.7 when I run def binary : 1 (x y) y; def testfor (x) (for c = 1, c<2 in x = x +1 ) : x; testfor(1) unexpectadly get 3.000000 instead of 2.000000. This happens, I believe, because the

Hi Dan, The tutorial in r119335 does not build : the basicAA pass creation needs to be declared. This is addressed with the 'missing-include' patch, which updates both source code & documentation. The second point is that beside basicAA, to get the optimizations as shown in the tutorial, (sin(x)*sin(x) -> sin(x)^2), some attributes need to be set on 'sin'. Patch

SUCCESS! Sorry, I had removed the addFnAttr() call by accident. Using the basicAA pass and ReadOnly, as you suggested, works like a charm! :) > -----Original Message----- > From: Rob Pieke > Sent: Monday, November 15, 2010 4:40 PM > To: 'Duncan Sands' > Cc: 'llvmdev at cs.uiuc.edu'; 'Dan Gohman' > Subject: RE: [LLVMdev] Optimization of calls to

In the tutorial, it shows that multiple calls to pure functions (sin, cos) can be optimized. Without the

Still no luck after switching to: theFPM->add( new llvm::TargetData( *theExecutionEngine->getTargetData() ) ); theFPM->add( llvm::createBasicAliasAnalysisPass() ); theFPM->add( llvm::createInstructionCombiningPass() ); theFPM->add( llvm::createReassociatePass() ); theFPM->add( llvm::createGVNPass() ); theFPM->add( llvm::createCFGSimplificationPass() ); Based on output

Hi Rob, You need to set attribute ReadOnly on the sin / cos functions, using Function::addFnAttr(Attribute) for example.

https://llvm.org/docs/tutorial/LangImpl04.html has an example where the function `foo` gets redefined, and the JIT returns evaluation of the latest definition. I thought my code was wrong, but it seems that the binary produced by `ninja Kaleidoscope-Ch4` has the same bug. Granted, my LLVM checkout is from Nov 3 2018 (r346062). Is this a known issue? ~Nick Desaulniers

Hi, The Ocaml Kaleidoscope tutorial code stops compiling at chapter 3. I get $ ocamlbuild toy.byte Finished, 1 target (0 cached) in 00:00:00. + /usr/bin/ocamlc -c -o codegen.cmo codegen.ml File "codegen.ml", line 5, characters 0-9: Error: Unbound module Llvm This is with Llvm 2.7 on ubuntu 10.10. I have the package libllvm-ocaml-2.7-dev installed. The offending line is simply open

I try to understand cmake build configuration. As an example, I copied Kaleidoscope from llvm examples to some other directory (e.g., /tmp/Kaleidoscope). What change(s) that I need to make to "CMakkeLists.txt" in order to build Kaleidoscope from /tmp/Kaleidoscope? Thank you. -------------- next part -------------- An HTML attachment was scrubbed...

I'm doing testing on this at the moment. But to start with: >>Because music represents an analog signal, As I wrote, it would only apply to specific genres, not analog recordings. Electronic music quite often doesn't leave a computer these days. And it mainly consists of drums, synths & vocals/effects. Drums are often samples sequenced at sample (not sub-sample) accuracy,

Hi Nick, I was not aware of it, but it makes sense given the recent switch to ORC2, which has different symbol resolution rules. I am out on vacation this week, but will take a look when I get back and see if I can restore the old behavior. Cheers, Lang.

You'll probably want to take a look at the

Are the Kaleidoscope examples supposed to work on Windows? e.g. C:\llvm\examples\Kaleidoscope\Orc\initial\toy.cpp when I try to compile this with clang it gives compile time error messages, and when I try with Microsoft C++ it generates an executable that runs but crashes when I type in an expression; I get similar results with a few of the other versions. I can give more detailed feedback if

Hi Rob, > Hmm ... I tried setting that right after Function::Create but I still get the same result (though flagged with "readonly") did you run the gvn pass (preceded by basic-aa)? Ciao, Duncan.

Not yet unfortunately. I've had my head down working on a jut-linker replacement. Let me take a look right now...
