If you are familiar with the LLVM tutorial you will see its influence on this compiler which leverages idioms, strategies, and code fragments from the tutorial. The LLVM tutorials are a great starting point for understanding the APIs in the context of compiling. There is lots of great advice ...
llvm 1 use the cc1 for generating IR: clang -cc1 -emit-llvm testfile.c -o testfile.ll http://llvm.org/docs/LangRef.html 2 To convert LLVM IR in test.ll to bitcode format, llvm-as test.ll –o test.bc hexdump -C test.bc http://llvm.org/docs/BitCodeFormat.html#abstract 3 Con...
LLVM IR 有三种表示格式,第一种是 bitcode 这样的存储格式,以 .bc 做后缀,第二种是可读的以 .ll,第三种是用于开发时操作 LLVM IR 的内存格式。 一个编译的单元即一个文件在 IR 里就是一个 Module,Module 里有 Global Variable 和 Function,在 Function里有 Basic Block,Basic Block 里有 指令 Instruction...

The LLVM project has multiple components. The core of the project is itself called “LLVM”. This contains all of the tools, libraries, and header files needed to process intermediate representations and converts it into object files. Tools include an assembler, disassembler, bitcode analyzer, an...
of chapter 1 does conversion of C source to LLVM assembly(IR), converting IR to LLVM bitcode, and converting bitcode to target machine language, and converting back to IR, linking and executing bitcode. then theres a section of clang exercises. Mostly thisis good for command line ...

LLVM is a statically typed intermediate representation and an associated toolchain for manipulating, optimizing and converting this intermediate form into native code. LLVM code comes in two flavors, a binary bitcode format (.bc) and assembly (.ll). The command line tools llvm-dis and 1lvm-as...
