使用LLVM实现一门语言(三)Code Generation to LLVM IR Will Zhang 机器学习框架开发者 34 人赞同了该文章 终于开始codegen了,首先我们include一些LLVM头文件,定义一些全局变量 #include "llvm/ADT/APFloat.h" #include "llvm/ADT/STLExtras.h" #include "llvm/IR/BasicBlock.h" #include "llvm/IR/Constants...
只要保证各函数的名字与用户指定的函数名一致,我们就可以利用LLVM的符号表替我们完成函数名的解析。 拿到待调用的函数之后,就递归地生成传入的各个参数的代码,并创建一条LLVM call指令。注意,LLVM默认采用本地的C调用规范,这样以来,就可以毫不费力地调用标准库中的“sin”、“cos”等函数了。 Kaleidoscope中的四种基...

The LLVM target-independent code generator is a framework that provides a suite of reusable components for translating the LLVM internal representation to the machine code for a specified target—either in assembly form (suitable for a static compiler) or in binary machine code format (usable for ...
MLIR 是一种常见的 IR,也支持硬件特定的操作。因此,对围绕 MLIR 的基础架构的任何投资(例如,对其进行工作的编译器通过),都应该产生良好的回报;许多目标可以使用基础架构受益。 MLIR 是一个强大的表示,但也有非目标。不尝试支持低级机器代码生成算法(如寄存器分配和指令调度)。更适合较低级别的优化器(例如 LLVM)。
We would like to express our gratitude for our beloved Head of the Department Dr.D.Manjula,for providing us with the facilities in our depart- ment that help us in our project. We thank our parents, family, and friends for bearing with us throughout the course of our project and for ...
On linking stage you'd probably need to link some "runtime" libraries, numba ones in this case. You can compile it with clang, just make sure your IR have .bc or .ll extensions. But the proper way is to use llc or LLVM API to compile down to native code, and then link it using...
Rellume is a lifter for x86-64/AArch64/RISC-V64 machine code to LLVM IR with focus on the performance of the lifted code. The generated LLVM IR can be compiled and executed again, for example using LLVM's JIT compiler, ideally having the same (or even better) performance as the origi...
Consequently, any supported high-level programming language is transformed to this IR bytecode as part of the LLVM compilation process. Our metamorphic generator functions at the IR bytecode level, which provides many advantages over morphing at the assembly or source code level. The morphing ...
Alive, a tool by Nuno Lopes from Microsoft Research, is a formal verification tool that was used to ensure the patterns and preconditions are correct before implementing them. It uses a language similar to LLVM IR and the Z3 theorem prover to verify if an input pattern is equivalent to the...
