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...

Hi all, Starting from Chapter 4 of the Kaleidoscope tutorial (where the JIT support is added), there's some strange behaviour, ready> def foo(x y) x+y; ready> Read function definition: define double @foo(double %x, double %y) { entry: %addtmp = fadd double %x, %y ret double %addtmp } ready> foo(1, 2); ready> Evaluated to 3.000...

...arked as executable. That happens inside finalizeObject, which also invalidates the code cache. Even so, this will likely only work in cases where code generation is only invoked once. You are correct that MCJIT won't work in this case because of the function-by-function approach used in the Kaleidoscope example. Basically, with MCJIT once code has been generated for a module nothing else can be added to the Module. Making Kaleidoscope work with MCJIT would require introducing some sort of scheme where a new module was created each time a new function was created. In the current implementation...

Hi all, I tried to modify Kaleidoscope Tutorial (toy.cpp from llvm/examples/Kaleidoscope/Chapter7, LLVM 3.3 release branch) in order to use MCJIT instead of JIT. I get segmentation fault when running toy.cpp with fibonacci example from the tutorial. My modified toy.cpp is in attachment and still works with JIT (when #define USE_MCJ...

(cc'ing llvm-dev) Hello Gregory, i just recompiled llvm from scratch, and was able to build the ocaml kaleidoscope bindings. Did you know the llvm's build system already can compile the kaleidoscope tutorials for you? You can run this to build them: make BUILD_EXAMPLES=1 Or just cd into the examples directory in your build directory, and run "make" there. Anyway, I think the problem you're...

Cheers Lang! You were right, I was testing this on Linux. I was planning on committing these changes with the corresponding changes to the Kaleidoscope tutorial walk-through. Might be a bit of a surprise to have no explanation of what MCJITHelper and friends is doing. I'll try and make time to prepare some patches along these lines, as well as updating future chapters with the same fix. Thanks for taking a look :) Charlie. On 16 January 2...

...ionCache. So why lli.cpp does call JMM->invalidInstructionCache() explicitely again ? Also I think there is a bug in MCJIT::getPointerToFunction: ... StringRef BaseName = F->getName(); if (BaseName[0] == '\1') ... When BaseName is empty it triggers assertion. For example in Kaleidoscope tutorial an unnamed function is created. > > Even so, this will likely only work in cases where code generation is only invoked once. > > You are correct that MCJIT won't work in this case because of the function-by-function approach used in the Kaleidoscope example.

Hi, I am building a new JIT compiler for Lua (actually a derivative of Lua), and am planning to use LLVM for this. I have trying out some basic functions using LLVM 3.5.1. I have been puzzled by one aspect of the MCJIT versions of the Kaleidoscope sample, and would hugely appreciate some insight. Can a single MCJIT instance be used to manage several modules? Why is a separate MCJIT instance created for each module? Unfortunately the tutorial text does not explain the rationale for this. At the moment in my implementation I am putting eac...

I didn't update the OCaml documentation or examples yet. It looks like the OCaml bindings don't expose

To try to find out why it was crashing, I followed the trail of function calls: C:\llvm\examples\Kaleidoscope\Orc\initial\toy.cpp auto ExprSymbol = J.findUnmangledSymbol("__anon_expr"); JITSymbol findUnmangledSymbol(const std::string Name) { return findSymbol(mangle(Name)); } JITSymbol findSymbol(const std::string &Name) { return CompileLayer.findSymbol(Name, true);...

...shown in the tutorial, (sin(x)*sin(x) -> sin(x)^2), some attributes need to be set on 'sin'. Patch 'set-attribute' address this. Of course, this is probably not the right way to achieve this in real life with a real programming language / environment, but within the scope of the kaleidoscope, this should be sufficient. This patch updates both the source code & documentation.

Hi all, I am new to LLVM and have been working through the Kaleidoscope tutorial. Everything is working fine so far except for local externs (as opposed to things like the math functions, which are working). Note that I have seen this bug with the reference code listing, as well as my own code. link to code: https://llvm.org/docs/tutorial/LangImpl05.html#full-code-lis...
