Qbe compiler

  • What is the difference between LLVM and QBE?

    To save its users from having to implement it, LLVM provides stack slots.
    This means that one increment of a variable v will be composed of three LLVM instructions: one load, one add, and one store.
    QBE provides simple non-SSA temporaries, so incrementing v is simply done with one instruction %v =w add %v, 1 ..

  • What is the intermediate language in QBE?

    The intermediate language (IL) is a higher-level language than the machine's assembly language.
    It smoothes most of the irregularities of the underlying hardware and allows an infinite number of temporaries to be used.
    This higher abstraction level lets frontend programmers focus on language design issues..

qbe is an optimizing compiler backend which consumes programs in a simple intermediate language, optimizes them, and emits assembly for x86_64, aarch64, or riscv64, aiming to achieve “70% of the performance” of advanced compilers like LLVM in “10% of the code”.

What is a QBE compiler?

The compiler uses QBE as one of its backends.
A C compiler from Benjamin Rosseaux that reuses the IL design and many passes from QBE.
QBE is used as main practice material for a class on compilers given by the Russian ISPRAS institute.

What is QB64 compiler?

QB64 (originally QB32) is a self-hosting BASIC compiler for Microsoft Windows, Linux and Mac OS X, designed to be compatible with Microsoft QBasic and QuickBASIC.QB64 is a C++ emitter, which is integrated with a C++ compiler to provide compilation via C++ code and GCC optimization.

What is QBE & why should I use it?

Plus:

  • Plan 9 "QBE aims to be a pure C embeddable backend that provides 70% of the performance ofadvanced compilers in 10% of the code.
    Its small size serves both its aspirations ofcorrectness and our ability to understand, x, and improve it.

    • What operating systems does QBE support?

    The current version of QBE can target amd64 (linux and osx), arm64, and riscv64 .
    The snippet below is a self-contained program written in QBE intermediate language that shows how to define simple functions, perform arithmetic on words, and call into a variadic C function.
