Kaleidoscope is a C++ library typically used in Internet of Things (IoT), Arduino applications. Kaleidoscope has no bugs, it has no vulnerabilities, it has a Strong Copyleft License and it has low support. You can download it from GitHub.

Flexible firmware for Arduino-powered keyboards. This package contains the "core" of Kaleidoscope and a number of example firmware "Sketches". If you're just getting started with the Keyboardio Model 01, the introductory docs are here and the source for the basic firmware package is here: It's probably a good idea to start there, learn how to modify your keymap and maybe turn some modules on or off, and then come back to the full repository when you have more complex changes in mind.

            LLVM printing IR calls
            Asked 2021-May-25 at 17:16

            I am following LLVM Kaleidoscope tutorial, 3rd chapter and it seems that additional information is being printed out on compiled code when an operation is run.

            The reason you're getting a Parsed a top-level expr is because you most likely changed that string yourself.

            If you visit the body for HandleTopLevelExpression, you see where the tutorial prints this message.

            https://llvm.org/docs/tutorial/MyFirstLanguageFrontend/LangImpl03.html#full-code-listing

            The printing of LLVM IR to stderr is done with various llvm::Value::print, called on the line below the one where it writes Read top-level expression.

            To conclude, your code is missing parts from the code listing in the tutorial

            global variable not found in llvm JIT symbol table
            Asked 2020-Dec-10 at 15:42

            I am trying to get a llvm::Module with a global variable to compile with the KaleidoscopeJIT Compiler, however, I get an error in the symbol lookup from the JIT compiler. (KaleidoscopeJIT.h source code from https://github.com/llvm-mirror/llvm/blob/master/examples/Kaleidoscope/include/KaleidoscopeJIT.h )

            Upon inspection of the Symbol Table in the LegacyRTDyldObjectLinkingLayerBase, I indeed see that the global variable has not been added to Symbol table. Is this because the global variable is uninitialized? If so how should I specify an initializer for a struct using the llvm C++ api?

            The problem seems to be that uninitialized global variables are somehow optimized out and not added to the symbol table.

            A quick work around to ensure that the variable gets added to the symbol table is to initialize it with an "Undefined value".

            The following code allows to do such an initialization with the c++ api

            Why operator precedence must be increased by 1 when `TokPrec < NextPrec` in expression parser?
            Asked 2020-Oct-15 at 14:39

            The code in appendix from LLVM tutorial Kaleidoscope: Implementing a Parser and AST -> Chapter 2 -> Binary Expression Parsing is a simple lexer and parser.

            Below is a snippet from the expression parser section:

            ...

            ANSWER

            Answered 2020-Oct-15 at 14:39

            All of Kaleidoscope's operators are left-associative, which allows a simplification in the operator-precedence algorithm, at the cost of a lack of flexibility [Note 1]. So it probably is not a good basis for implementing operator-precedence parsers.

            The main loop in ParseBinOp combines a series of equal-precedence operators, avoiding recursion. When it encounters a higher precedence operator, though, it must recurse, and it needs to do so in a way that will not absorb too much of the rest of the expression. In particular, the recursive call must not absorb an operator of equal precedence. Hence the + 1.

            If you remove the +1 then certain expressions will be parsed as though some of their operators were right-associative. It might be a bit tricky to find a counterexample, particularly since the only non-commutative operators are - and <. Without actually trying, I guess that you would get an incorrect parse of a-b*c-d.

            Notes:
            1. This comes home to roost later, when assignment is added to the language. Assignment is usually right-associative to allow chained assignments, but Kaleidoscope forces the use of parentheses: x = ( y = 0 ).

            Set LLVM assembly output syntax with C++ API
            Asked 2020-Oct-14 at 15:48

            I'm trying to find a way to set the assembly syntax that LLVM outputs (for x86 in particular). Following the Compiling to Object Code section of the Kaleidoscope tutorial, I'm outputting assembly files with

            ...

            ANSWER

            Answered 2020-Oct-14 at 15:48

            Here's a few things I found out by reading the LLVM source:

            • The output assembly syntax is controlled by the AssemblyDialect member in llvm::MCAsmInfo. For x86 the derived classes of llvm::MCAsmInfo can be found in X86MCAsmInfo.h and X86MCAsmInfo.cpp.
            • The member AssemblyDialect is initialized to the value of AsmWriterFlavor, which is set by the command line option x86-asm-syntax.

            As far as I could tell AssemblyDialect isn't referenced anywhere else in the code base, so the only way to set it is by the x86-asm-syntax flag. For that you can use llvm::cl::ParseCommandLineOptions. Minimal example for setting the assembly syntax to intel:

            Linking to external functions in dynamic libraries with LLVM
            Asked 2020-Sep-30 at 21:36

            In my project, I am emitting LLVM IR which makes calls to external functions in dynamic libraries.

            I declare my external functions like:

            ...

            ANSWER

            Answered 2020-Sep-30 at 21:36

            I figured it out— I was missing that I need to call llvmlite.binding.load_library_permanently(filename) in order for the external symbols to become available. Even though the library is already in memory, the function still needs to be invoked. (This corresponds to the LLVM native function llvm::sys::DynamicLibrary::LoadLibraryPermanently()).

            From this answer, it appears calling the above function with nullptr will import all the symbols available to the process.

            Oddly, on OSX, I found that the external symbols were available even though load_library_permanently() had not been explicitly called— I'm not sure why this is (perhaps the OSX build of llvmlite itself happened to call the function with nullptr, as above?).

            ANSWER

            Answered 2020-Jul-21 at 16:37

            I think the problem might be that $(llvm-config --cxxflags) doesn't work properly in macOS. I don't know exactly what it is with --cxxflags, but I personally experienced a problem that $(llvm-config --libfiles) didn't return the correct path to the shared library libLLVM in macOS (that command worked in Linux anyway).

            However, I suggest to use CMake, which you will need anyway when working with LLVM. Below is a sample CMake code copied from the LLVM website. I followed this CMake code and can compile my project in macOS.

            How to assign pixels to each part of the image?
            Asked 2020-Apr-03 at 05:49

            I'm writing a functional that will apply a kaleidoscope effect to an image. So the original image and after applied effect image looks like these two images below respectively (very bottom).

            I cannot import anything else other than importing Image from PIL. But I have already written a few functions that helps with the effects, such as (1)resize_image which resizes the image to a quater size, (2)flip_horizontally which horizontally flips the image(top left quadrant), (3)flip_vertically, which vertically flips the image(bottom right quadrant), and combining the previous two functions to get the top right quadrant image of the second image.

            Install Kaleidoscope

            If you want to use Kaleidoscope to customize or compile a "sketch" to power a supported keyboard, the fastest way to get started is to use the Arduino IDE. You can find setup instructions on kaleidoscope.readthedocs.io. If you prefer to work from the command line or intend to work on Kaleidscope itself, please follow the instructions below. It's important to note that the Arduino IDE needs the source code laid out in a slightly different arrangement than you'll find in this repository. If you want to use the Arduino IDE, you should follow these instructions instead.
